                   Call to Order and Opening Remarks

 

                DR. GOODMAN:  Welcome to day two of this

 

      joint two-day session of the Psychopharmacologic

 

      Drugs Advisory Committee and the Pediatric Advisory

 

      Committee being held on September 14, 2004, here at

 

      the Holiday Inn in Bethesda, Maryland.

 

                We are convened to address recent concerns

 

      about reports of suicidal ideas and behavior

 

      developing in some children and adolescents during

 

      treatment of depression with selective serotonin

 

      reuptake inhibitors and other antidepressants.

 

                Our goal is to gather information from a

 

      variety of sources and perspectives to help us

 

      understand this complex situation and ultimately,

 

      to offer the best possible recommendations to the

 

      FDA.

 

                Now, I would like to turn the microphone

 

      to Anuja Patel of the FDA Center for Drug

 

      Evaluation and Research and Executive Secretary of

 

      this committee to read the conflict the interest

 

      statement into the record.

 

                                                                 6

 

                     Conflict of Interest Statement

 

                MS. PATEL:  Good morning.  The following

 

      announcement addresses the issue of conflict of

 

      interest and is made a part of the record to

 

      preclude even the appearance of such at this

 

      meeting.

 

                The topics to be discussed today are

 

      issues of broad applicability.  Unlike issues

 

      before a committee in which a particular company's

 

      product is discussed, issues of broader

 

      applicability involve many industrial sponsors and

 

      products.

 

                All Special Government Employees and

 

      invited guests have been screened for their

 

      financial interest as they may apply to the general

 

      topics at hand.

 

                The Food and Drug Administration has

 

      granted particular matter of general applicability

 

      waivers under 18 U.S.C. 208(b)(3) to the following

 

      Special Government Employees which permits them to

 

      participate fully in today's discussion and vote:

 

      Jean Bronstein, Dr. Joan Chesney, Dr. Wayne

 

                                                                 7

 

      Goodman, Dr. Lauren Marangell, Dr. James McGough,

 

      Dr. James Perrin, Dr. Bruce Pollock.  In addition,

 

      Dr. Philip Wang has been granted a limited waiver

 

      that permits him to participate in the committee's

 

      discussions.  He is, however, excluded from voting.

 

                A copy of the waiver statements may be

 

      obtained by submitting a written request to the

 

      Agency's Freedom of Information Office, Room 12A-30

 

      of the Parklawn Building.

 

                In addition, Dr. Judith O'Fallon and Dr.

 

      Victor Santana have de minimis financial interests

 

      under 5 CFR Part 2640.202 that are covered by

 

      regulatory waiver under 18 U.S.C. 208(b)(2).

 

                Because general topics impact so many

 

      entities, it is not practical to recite all

 

      potential conflicts of interest as they apply to

 

      each member, consultant, and guest speaker.

 

                FDA acknowledges that there may be

 

      potential conflicts of interest, but because of the

 

      general nature of the discussion before the

 

      committees, these potential conflicts are

 

      mitigated.

 

                                                                 8

 

                With respect to FDA's invited industry

 

      representative, we would like to disclose that Dr.

 

      Dilip Mehta and Dr. Samuel Maldonado are

 

      participating in this meeting as industry

 

      representatives acting on behalf of regulated

 

      industry.  Dr. Mehta is retired from Pfizer and Dr.

 

      Maldonado is employed by Johnson & Johnson.

 

                With respect to all other participants, we

 

      ask in the interest of fairness that they address

 

      any current or previous financial involvement with

 

      any firm whose product they may wish to comment

 

      upon.

 

                Thank you.

 

                DR. GOODMAN:  Thank you, Anuja.

 

                We will be starting off this morning with

 

      a presentation from Tom Laughren who will give us

 

      an overview and also pose the questions, the five

 

      questions to this committee.

 

                Following his presentation, I would invite

 

      questions.  I also think it would be a good time

 

      before we get into the meat of our discussions to

 

      ask representatives from the FDA questions, to

 

                                                                 9

 

      further interrogate some of the data that was

 

      presented yesterday.

 

                Before we get into the actual discussion

 

      of the questions, I would like us to think of the

 

      questions that were carried over from yesterday,

 

      pose those, and then we will take a short break,

 

      reconvene and start the process of discussing the

 

      questions.

 

                Is that clear?  Okay.

 

                Tom, are you ready?

 

                            Opening Comments

 

                         Thomas Laughren, M.D.

 

                DR. LAUGHREN:  Good morning.  I would also

 

      like to welcome everyone back to the meeting today.

 

      I would like to do a couple of things in my few

 

      minutes here.

 

                First of all, what I want to do is to

 

      briefly review what I think are some of the key

 

      findings from Dr. Hammad's presentation yesterday,

 

      so that you have these in mind as you are

 

      considering the questions before you.

 

                Then, I want to talk a little bit about

 

                                                                10

 

      what I think the data mean and talk about what some

 

      of the regulatory options are as you are

 

      considering our questions, and then I want to go

 

      over the questions and the topics again.

 

                These are the 24 trials that we are

 

      considering. Again, 16 of them were in major

 

      depression, and the other 8 trials were in several

 

      various psychiatric disorders - OCD, GAD, 1 in SAD,

 

      and 1 in ADHD.

 

                Again, just for summary, I think these are

 

      the three contributions that the Division made to

 

      this effort. Again, we went to a lot of effort to

 

      make sure that we had complete case finding.  With

 

      the help of Columbia, we accomplished what I think

 

      is a rational classification of these events, and

 

      we both obtained and included patient level data in

 

      our analysis of the suicidality data again to try

 

      and understand some of the differences both between

 

      trials, within programs and across programs.

 

                These are the outcomes that we looked at

 

      again. The focus of the analysis was on two areas,

 

      the suicidality event data and also on the suicide

 

                                                                11

 

      item data.

 

                For the event data, could we have the

 

      other slide up that we had running yesterday?  Our

 

      primary endpoint, as you recall, was the

 

      combination of suicidal behavior and ideation,

 

      Codes 1, 2, and 6, where 1 was suicide attempt, 2

 

      was preparatory actions, and then 6, suicidal

 

      ideation.

 

                So, that was our primary endpoint, but we

 

      also looked at secondary endpoints, at suicidal

 

      behavior, in other words, Codes 1 and 2, and then

 

      suicidal ideation, Code 6, and then for our

 

      sensitivity analysis, we looked at this larger

 

      outcome including 1, 2, and 6, but also adding in 3

 

      and 10, where again, 3 is self-injurious behavior

 

      where the intent is not known, and 10 is not enough

 

      information.  Again, these are the cases where

 

      there is injury, but it is not possible to tell

 

      whether it's self-injury or other injury.

 

                With regard to the suicide item data, we

 

      looked at two measures about worsening suicidality

 

      on that item or emergence, and these again are the

 

                                                                12

 

      cases where the patients are normal at baseline and

 

      have some increase during the trial.

 

                In terms of our analytical plan, the major

 

      focus was on doing risk ratio analyses, both for

 

      the suicidality event data and for the item data.

 

      In both cases, we looked at individual trials, as

 

      well as for the event data, we looked at various

 

      pools.

 

                We looked at both by drug, we combined all

 

      the SSRIs, MDD trials as a group, we looked at all

 

      of the other indications combined as a group and

 

      also did one pooling which included all 24 trials.

 

      For the item data, we looked again at individual

 

      trials and then a pooled analysis over all trials.

 

                Dr. Hammad put a lot of effort into again

 

      trying to explain the differences that we were

 

      seeing between trials within programs and across

 

      programs, and I just want to spend a couple of

 

      minutes talking about exactly what he did.

 

                He looked for confounding within trials

 

      using both the univariate approach and a

 

      multivariate approach.  There were a total of 17

 

                                                                13

 

      covariates that he looked at.  He was not able to

 

      find any evidence for important confounding in that

 

      search.

 

                He also did stratified analysis to explore

 

      for effect modification.  The three variables that

 

      he looked at were age, gender, and history of

 

      suicide attempt or ideation, so basically, what he

 

      did in each of these is to stratify on these

 

      variables within trials to look to see if there was

 

      basically an interaction.

 

                Again, he did not find any evidence for

 

      that, so basically, what that means is that on

 

      these variables, you find the signal both in

 

      children and adolescents, you find it both in males

 

      and females, and you find it both in those with and

 

      without history of suicide attempt or ideation.

 

                Finally, he looked at 12 trial level

 

      covariates, again, as an attempt to try and explain

 

      the differences across trials using a

 

      meta-regression approach.  Again, that approach was

 

      not able to explain the variability.

 

                Now, I would say that one of the problems

 

                                                                14

 

      in doing these kinds of explorations is that there

 

      is very limited power, you have a very small number

 

      of events.  When you use an eyeball approach to the

 

      data, you can't help but thinking that trial

 

      differences might have made a difference.

 

                I just use the TADS, the fluoxetine

 

      situation as an example.  The company had three

 

      trials.  There was no signal coming from those

 

      three trials.  If you look at the careful screening

 

      that was done to obtain the patients for those

 

      samples, and the exclusions of patients with prior

 

      histories of treatment resistance, and so forth,

 

      and then you look at the TADS sample, which is many

 

      ways was probably more representative of the

 

      community of patients who actually get treated,

 

      there is quite a difference.  Again, as you recall,

 

      in the TADS trial, you see quite a striking signal

 

      for suicidality.

 

                So, even though quantitatively, we weren't

 

      able to tease that out and to explain the

 

      differences using various quantitative approaches,

 

      it is hard to think that that may not have made a

 

                                                                15

 

      difference.

 

                In my next three slides, I am going to

 

      present very briefly some of the data.

 

                What this slide is, is presenting the risk

 

      ratios for various poolings.  So, in this column,

 

      you have the risk ratios on our primary endpoint,

 

      which was suicidality ideation or behavior, 1, 2,

 

      and 6.

 

                In the second column, you have this

 

      expanded sensitivity analysis, 1, 2, 6, plus adding

 

      3 and 10.  The first row is all trials, so this is

 

      a pooling across all 24 trials.  In the second row,

 

      you have the pooling of the 11 trials with SSRIs

 

      and major depression.

 

                Now, there are two things I want you to

 

      notice about this slide.  First of all, in every

 

      case, the risk ratios are around 2.  They range

 

      from 1.7 to 2.2, but they are sort of in the

 

      vicinity of 2.

 

                Secondly, if you look at the confidence

 

      intervals on these risk ratios, in every case, it

 

      does not include 1, so in that sense, it is a

 

                                                                16

 

      statistically significant finding. So, this is the

 

      pooled data.

 

                What I have given you in this slide are a

 

      different set of poolings.  Here, what I am doing

 

      is pooling the individual depression trials in the

 

      7 programs that looked at depression, and these are

 

      the 7 programs listed here.  Every row is a

 

      separate depression program.

 

                What I have given you here, first of all,

 

      is the outcome on our primary endpoint a

 

      combination of 1, 2, and 6.  I have also given you,

 

      in the second column, the outcome on suicidal

 

      behavior, and in the third column, the outcome on

 

      suicidal ideation.

 

                There are a couple of things I want you to

 

      notice about this slide.  First of all, in every

 

      instance where we have events, and we had no events

 

      for Serzone, but in the other 6 instances where you

 

      have events, the risk ratio is always greater than

 

      1.

 

                Now, I want to turn to trying to tease

 

      apart where that overall effect is coming from if

 

                                                                17

 

      you break it apart by behavior and ideation.  Dr.

 

      Hammad made this point yesterday, in three cases it

 

      appears as if the overall effect is coming from

 

      behavior, in three cases it looks like it is coming

 

      from ideation.

 

                So, if you look at Celexa, here is the

 

      risk ratio for behavior, 2.23.  There is nothing

 

      happening for ideation.

 

                If you look at Paxil, again, it looks like

 

      it is coming mostly from behavior.

 

                If you look at Prozac, it looks like it is

 

      probably coming more from behavior than from

 

      ideation.

 

                For Effexor, there is a signal coming from

 

      both, but it is clearly coming more from ideation.

 

      Here, the confidence interval is almost

 

      significant.

 

                For Remeron, it is all coming from

 

      ideation, and from Zoloft, there is nothing

 

      happening for behavior, it is all coming from

 

      ideation.

 

                I am not sure what this means.  As Dr.

 

                                                                18

 

      Hammad pointed out, this may simply be a small

 

      numbers problem, but we are not seeing a consistent

 

      finding in terms of where the overall effect is

 

      coming from.

 

                Finally, what I have given you in this

 

      slide is the data from the individual other 8

 

      trials in non-MDD indications.  As you get into

 

      these trials, the number of events you are dealing

 

      with is very small, and just to illustrate that, I

 

      have put the actual number of events in this slide.

 

                So, in each of these parentheses, the

 

      first one is the number of events for drug, and the

 

      second one is for placebo.  So, you can see the

 

      small number of events that we are dealing with.

 

                If you recall from the previous slide, for

 

      Effexor, we were seeing quite a strong signal for

 

      major depression.  These are two GAD studies.

 

      There is nothing at all happening here.

 

                For Luvox, again, Luvox was only studied

 

      in OCD, there was no depression trial.  Just one

 

      study in depression, only two events.  They were

 

      both happening in the drug group.

 

                                                                19

 

                For the two non-MDD Paxil studies, one in

 

      social anxiety, one in OCD, again, small numbers of

 

      events, but in both cases, they were happening in

 

      the drug group.

 

                The same for the Prozac OCD, just one

 

      event, but it happened in the drug group.

 

                No events for Wellbutrin.

 

                For Zoloft, this is the only case where

 

      the one event is happening in placebo, and not in

 

      drug.

 

                It is hard to know what to make of all of

 

      this, although the one thing that you can't help

 

      noticing is that even though there are a small

 

      number of events, where events occurred, they most

 

      happen on the drug side.

 

                Just to summarize these data, again, if

 

      you look at various pooled analyses, the risk

 

      ratios hover around 2.  They range from 1.7 to 2.2.

 

      In all cases for those poolings, it appears to be a

 

      significant finding.

 

                The signal appears to be coming mostly

 

      from major depression, although perhaps not

 

                                                                20

 

      exclusively.  Despite those findings, there still

 

      are these inconsistencies in this risk, both across

 

      trials, within programs and across programs.

 

                On the other hand, my view is--and there

 

      isn't necessarily one consistent view coming out of

 

      FDA on this--but my view is that this is a

 

      reasonably consistent signal for risk.  You are

 

      seeing it in seven of nine programs.  We don't see

 

      any events in Wellbutrin.  On the other hand,

 

      Wellbutrin was only studied in ADHD, just one

 

      trial.

 

                There is no signal coming from Serzone,

 

      which was studied in major depression.  I am not

 

      sure if that means that Serzone is free of risk or

 

      it simply may mean that the events, the

 

      ascertainment in those programs was not good enough

 

      to pick them up.  I don't know the answer.

 

                One other point that Dr. Hammad made

 

      yesterday, that I want to return to, is a way of

 

      thinking about this risk is in terms of risk

 

      difference, and if you look over all these trials

 

      and estimate what the risk difference is, that is

 

                                                                21

 

      the difference in the risk between drug and

 

      placebo, so you are subtracting the placebo risk

 

      from the drug risk, it is in the range of 2 to 3

 

      percent.

 

                What that means is that again, out of 100

 

      patients treated--this is short term now,

 

      short-term treatment--you can expect 2 or 3 out of

 

      that 100 will have some excess of suicidality above

 

      and beyond what would be in the background that is

 

      due to drug.

 

                As a clinician, what you have to do is to

 

      balance that risk against the perceived benefit.

 

      The problem here, of course, is that we only have,

 

      at least from FDA's standpoint, a demonstration of

 

      benefit for Prozac, but if you take the TADS trial

 

      as an example of benefit, there, you can look at

 

      the benefit difference, and the benefit difference

 

      in the TADS trial, difference between drug and

 

      placebo in percent of responders, using that as the

 

      measure of benefit, it is about 25 percent.

 

                Again, you can interpret that in the same

 

      way, so that if you look at 100 patients who are

 

                                                                22

 

      treated with fluoxetine, you can expect that about

 

      25 out of 100 will have that benefit if you are

 

      looking at response as the benefit.

 

                So, you balance that against the risk,

 

      which again in that trial, the risk actually was

 

      greater than the 2 percent, it was probably more on

 

      the order of 7 percent, but you balance that risk

 

      against the benefit.  That is the kind of calculus

 

      that a clinician has to do.

 

                Finally, as was pointed out, there were no

 

      completed suicides in any of these trials.

 

                Again, we did not see the same signal in

 

      looking at the item data.  One exploration we tried

 

      to do to see if that could be explained by patients

 

      dropping out, and unfortunately, that was not an

 

      explanation.  The analysis of completers did not

 

      show really any difference from the analysis of the

 

      patients who dropped out.

 

                So, how should these findings be

 

      interpreted?  I think that this is an indication

 

      that there may be some increased risk for

 

      suicidality during short-term treatment, and I

 

                                                                23

 

      think this is probably a class effect.  Again, you

 

      are not seeing it in every drug that we looked at,

 

      Serzone and Wellbutrin being the two exceptions,

 

      but I think there is enough here to suggest that

 

      this is probably a class effect.

 

                The signal appears to be most compelling

 

      in major depression.  It may not be limited to that

 

      population, but again we are left with this very

 

      unusual variation in the signal across trials,

 

      within programs and across programs that we have

 

      not been able really to explain.

 

                What I want to do next is to talk about

 

      what some of the regulatory options are, and I

 

      first want to talk about possible labeling changes.

 

                As you recall, we already made a fairly

 

      major change to labeling back in March, and all of

 

      those changes have now been implemented.  There is

 

      a fairly prominent warning statement that directs

 

      the attention of prescribers to this possible

 

      event.

 

                Now, that language as it currently is

 

      written suggests that causality has not been

 

                                                                24

 

      established.  One thing that might be done to

 

      modify that, if there is agreement on this, we

 

      could say that causality has now been established

 

      for this risk in pediatric patients.

 

                In addition to that, we could go beyond

 

      that and provide specific suicidality findings in

 

      the labels for different products.  We could also

 

      provide more specific information about the

 

      efficacy findings for specific products in that

 

      language.

 

                There are other things to talk about in

 

      terms of that warning statement including things

 

      like bolding language or putting black boxes.

 

      These are all options that are on the table.

 

                The other option that you need to think

 

      about, and you heard many yesterday in the open

 

      session ask us to do this, you can think about

 

      contraindications.  The one thing I want to point

 

      out is that in this country, for our label, a

 

      contraindication means never.  It means that that

 

      drug will never be used in treating these patients,

 

      it is not an option.

 

                                                                25

 

                The other thing I want to point out is

 

      that the term "contraindication" has different

 

      meanings in different regulatory settings.  In some

 

      settings, it does not mean never.  If you read the

 

      fine print in the UK, for example, there is a

 

      suggestion that specialists may still use that

 

      drug.  So, you need to keep that in mind that in

 

      this country, a contraindication means that that

 

      drug is never an option.

 

                In addition to labeling changes, there are

 

      some other obvious actions that we can and almost

 

      certainly will take.  Our plan at present is to

 

      write a medication guide. This is basically

 

      labeling which ideally would be attached to the

 

      medication when it is prescribed in unit of use

 

      packaging.

 

                In addition to that, we will undoubtedly

 

      have another public health advisory when we decide

 

      on what needs to be done, and we will try and

 

      communicate these findings to our partners.

 

                Now, what I would like to do again is to

 

      quickly go through the questions and the topics. 

 

                                                                26

 

      The first topic is again we would like to have your

 

      comments on our approach to classifying these cases

 

      and to our analysis of the data.

 

                One of the questions for which we really

 

      need to have you vote on is do you feel that the

 

      suicidality data from these trials support the

 

      conclusion that any or all of these drugs increase

 

      the risk of suicidality in pediatric patients.

 

                If the answer to that question is yes, to

 

      which of these nine drugs does this increased risk

 

      apply, in other words, is this a class effect for

 

      all antidepressants, does it apply to certain

 

      subclasses within this broader class, or to

 

      specific drugs?

 

                If this is a class risk or if it applies

 

      to certain drugs, how should this information be

 

      reflected in the labeling for each of these

 

      products, and what, if any, additional regulatory

 

      actions should the agency take?

 

                Finally, there is this question about what

 

      additional research is needed to further delineate

 

      the risks and the benefits of these drugs in

 

                                                                27

 

      pediatric patients with psychiatric illness.

 

                At our last meeting, I suggested one type

 

      of study that you might think about, and I am going

 

      to make that suggestion again, because we think

 

      that this is one study that might get at one of the

 

      deficiencies here, and that is, not only do we not

 

      have enough information about short-term benefit,

 

      we also have little information about longer term

 

      benefit or risk.

 

                One way of getting at longer term benefit

 

      is the randomized withdrawal study.  Basically, the

 

      way the study works is that patients who are

 

      responders or appear to be responding to treating,

 

      at some point in the course of treatment, are

 

      randomized to either continue on drug or randomized

 

      to placebo, and one looks at time to relapse as the

 

      outcome.

 

                Now, I know there are concerns about that

 

      design. You know, one concern is the ethical issue

 

      of taking patients off a medication when they

 

      appear to be responding. I agree that is a concern,

 

      but I think there is a way of dealing with that.

 

                                                                28

 

                The usual randomized withdrawal trial is

 

      done after too short a period of time on treatment.

 

      I mean typically, they are done now after 12 weeks

 

      or so of treatment.  That is too soon.  No

 

      clinician would take a patient off of one of these

 

      medications at that point in time.

 

                On the other hand, at some point in the

 

      course of treatment, whether it is six months or

 

      nine months or a year, it seems to me that it is a

 

      reasonable question.  At some point, you reach

 

      equipoise where the clinician has to ask the

 

      question, well, is this long enough, you know, is

 

      there any benefit in continuing the treatment

 

      beyond this point in time.

 

                Now, that is a much harder study to do, to

 

      keep patients on treatment for nine months or a

 

      year before you randomize them, but that would be a

 

      way of answering that important question of whether

 

      or not there is continuing benefit beyond that

 

      point in time.

 

                The other concern that has been raised

 

      about these trials is the issue of distinguishing

 

                                                                29

 

      between withdrawal symptoms and relapse.  Again, I

 

      agree that this is a reasonable concern, but I

 

      think there is also a way of addressing that.

 

                In clinical practice these days, these

 

      drugs are tapered.  One doesn't stop them cold

 

      turkey.  I think that could also be part of that

 

      design, and that could address that issue.  So,

 

      that is one thing to think about.

 

                Before I end, I want to leave you with two

 

      thoughts.  We clearly have an obligation at FDA to

 

      inform clinicians and patients about the risks that

 

      are associated with these drugs, and we take this

 

      obligation very seriously.

 

                Along those lines, I just want to point

 

      out that our current regulations do not require the

 

      same level of certainty with regard to safety in

 

      terms of causality as is required for efficacy.  In

 

      other words, we can issue warning statements with

 

      somewhat lesser certainty about causality than is

 

      required to support a claim.

 

                Secondly, as I have pointed out several

 

      times, the lack of efficacy data in this setting

 

                                                                30

 

      for most of these drugs needs to be part of this

 

      discussion.  On the other hand, and I am not making

 

      your job easy, please bear in mind that depression,

 

      whether in adults or children, is a very serious

 

      illness that is associated with morbidity and

 

      mortality quite apart from whatever role

 

      antidepressants might have.

 

                As was pointed out yesterday, this is the

 

      major cause of death in this population, the

 

      depression itself, so please bear that in mind.

 

                I have very profound respect and gratitude

 

      for the clinicians who are out there on the front

 

      lines still willing to take care of these patients

 

      despite what has become a very controversial and

 

      difficult environment.

 

                I hope that as we discuss these issues and

 

      make a decision, that we not make it impossible for

 

      them to practice medicine.

 

                Thank you.

 

                DR. GOODMAN:  Thank you, Tom, for a cogent

 

      and clear presentation.

 

                I would like to ask committee members if

 

                                                                31

 

      they have any questions of Tom.

 

                   Committee Questions and Discussion

 

                DR. FOST:  This is for Tom or anyone else

 

      who has a handle on the numbers.  I know there is

 

      no precise answer to it, but it would be helpful to

 

      me to just hear you or someone else, maybe Dr.

 

      Shaffer, if he is still here and is allowed to

 

      talk, this question.

 

                Suppose there were no SSRIs, suppose they

 

      were contraindicated, that is, prohibited,

 

      approximately, let me just ask the question about

 

      suicides, about completed suicides, and I

 

      understand there is no suicides in the FDA data,

 

      but based on everything that we know,

 

      approximately, would there be more suicides, fewer

 

      suicides, or the same amount if there were no SSRIs

 

      in children?

 

                DR. TEMPLE:  There is not going to be any

 

      way to answer that, in part because you can't do

 

      rigorous studies of the kind that would answer

 

      that.  No one is going to let you not treat, not

 

      institutionalize, et cetera, someone who is getting

 

                                                                32

 

      worse and worse, and it would require long-term

 

      studies presumably against no treatment, and it is

 

      not easy to figure out how anybody is going to do

 

      those.

 

                So, you are left with the kind of data

 

      that people have pointed out is always uncertain,

 

      the data on suicide rates and whether they are

 

      going up or down, so it is very hard to answer that

 

      question.

 

                There were no completed suicides in the

 

      pediatric data, so that doesn't give you a clue.

 

      You can form your own judgment about whether

 

      increased suicidal behavior or thinking is going to

 

      lead to suicides in a certain fraction of cases.

 

      It is hard to imagine that it couldn't, but you

 

      don't know what that ratio is.

 

                The success rate of suicidal attempts is

 

      relatively low.  I gather it is higher in males

 

      than females, but I don't think there is going to

 

      be ways to put numbers on that.

 

                You have to form your judgment about

 

      whether you think the overall decline in suicides

 

                                                                33

 

      has got something to do with therapy or has

 

      something to do with other aspects of life in the

 

      United States, and nobody can give you a firm

 

      answer to that, as Dr. Wysowski said and as others

 

      have said.  So, it is very hard to answer that

 

      question.

 

                Certainly, some of the people who spoke

 

      yesterday, some of the treating physicians were

 

      quite sure that they were helping people with the

 

      drugs, and you heard families who said that their

 

      relatives were made much worse by the drugs.

 

      Putting numbers on that, though, isn't feasible

 

      based on the data we have.

 

                DR. FOST:  A related question.  To those,

 

      Dr. Shaffer and others who note a decline in

 

      suicides in the United States, in parallel with the

 

      increased use of SSRIs, and let's just say which

 

      should be an increase in suicidality, suicidal

 

      ideation due to SSRI, what is the hypothesis there,

 

      that there is fewer suicides, but more suicidal

 

      ideation?  That is what the data seemed to suggest,

 

      and I am confused by that.

 

                                                                34

 

                DR. TEMPLE:  Can I make another comment?

 

      The studies you are looking at are all the

 

      short-term studies. As Tom was pointing out, we

 

      have none of the long term sort of relapse

 

      prevention data.  It seems entirely possible that a

 

      drug could be causing early suicidality, but once

 

      you are over that period, it prevents relapse,

 

      which could have an impact.

 

                You know, there is just literally no way

 

      to sort that out with present data.  I mean it has

 

      never been my thought that any benefit these drugs

 

      have consists entirely of their treatment of the

 

      acute episode, because in adults anyway, we have

 

      lots of data showing that the likelihood and timing

 

      of relapse is affected by continued therapy.

 

                As Tom said, most of those studies go

 

      earlier than you would like to do in a pediatric

 

      population, because they consistently show that

 

      quite reliably.  Maybe that is where their

 

      importance is, it is very hard to know.

 

                DR. GOODMAN:  Dr. Pine is next.

 

                DR. PINE:  I have a question about some of

 

                                                                35

 

      the regulatory options.  In thinking both about a

 

      number of the comments that were made yesterday, as

 

      well as your comments at the end about how

 

      difficult the decision that we will have today,

 

      related at least in part to the dearth of data that

 

      we really need.

 

                Are there any options from a

 

      pharmacovigilance standpoint as far as regulatory

 

      actions that might increase the degree to which we

 

      are focusing over the next time period on the

 

      emergence of these events or bring, you know, new

 

      data over the next months to years based on a

 

      regulatory action?

 

                DR. KATZ:  There is the mechanism of Phase

 

      IV requirements that say we can impose requirements

 

      on sponsors to do various studies in Phase IV and

 

      postmarketing environment.  The question would be

 

      what those studies would look like.  I think that

 

      is the question.

 

                There are other obviously entities, the

 

      NIMH and others who were set up obviously to do

 

      large trials, and again the question is what would

 

                                                                36

 

      those trials look like.  You could do I suppose

 

      large long-term, and again, you have heard, I

 

      think, a lot of people say that there is a need for

 

      long-term data.

 

                I suppose you could do long-term

 

      comparative trials, you can't do long-term

 

      placebo-controlled trials, so other than the sort

 

      of randomized withdrawal design I think that Tom

 

      talked about.

 

                So, there is a mechanism to require

 

      studies.

 

                DR. PINE:  I guess I am not so much asking

 

      about studies, and this maybe is a bit of an unfair

 

      analogy, but in New York, for example, as well as

 

      other states, whenever you write a prescription for

 

      a psychostimulant, there are a whole host of

 

      procedures that kind of go with that, that are

 

      designed to allow monitoring of the use of

 

      psychostimulants and the associated effects.

 

                Is there any--again, I realize I am

 

      thinking a little bit out of the box--is there any

 

      form of, I don't know, computer based or monitoring

 

                                                                37

 

      system that might give us a better handle on how

 

      many of these events are actually happening in

 

      regular treatment?

 

                DR. TEMPLE:  ODS should comment on that,

 

      but it is worth just looking at, say, the study Dr.

 

      Jick tried to do. There isn't any no-treatment

 

      group in that.  He is just comparing the risk with

 

      one group of drugs with another, and you can

 

      definitely do studies like that, but if you tried

 

      to compare treated people with untreated people,

 

      there will always be the concern of whether the

 

      groups are fundamentally different, a very

 

      difficult problem because people are treated.

 

                There might be environments in which

 

      treatment is not so common, where there is less

 

      likelihood to treat.  Maybe in those environments,

 

      you could do something like that, but Anne wanted

 

      to talk.

 

                DR. TRONTELL:  Just to expand briefly, you

 

      are talking about using observational data as Dr.

 

      Temple pointed out, where you don't have a control

 

      group, and although you might register patients, we

 

                                                                38

 

      have seen even in clinical trials that we have been

 

      discussing this past day, that the issue of

 

      ascertainment of these events is very complicated

 

      when you actually have a clinical trial mechanism

 

      in place to capture those events.

 

                The other challenge that you face with

 

      observational data, because people don't receive

 

      the drugs randomly, there is a phenomenon called

 

      "confounding by indication," in fact, some of your

 

      sicker patients you might presume are the ones who

 

      are getting the medication.

 

                We try and control for that, but it is

 

      very complex.  I think the better option is to

 

      think of some systematic way, and then you are in

 

      the realm of studies, as Dr. Katz was saying.

 

                DR. MURPHY:  I just wanted to follow up on

 

      one last thing.  Because we already know that using

 

      the system we have now for follow-up

 

      post-exclusivity because it is already mandated

 

      that we do one-year reporting once these products,

 

      whether they are approved or not, so we are looking

 

      at all-use.

 

                                                                39

 

                We do look at that and we report that, and

 

      we know that that is not going to inform us, you

 

      know, to answer the questions we need to answer,

 

      because of all the things that will impact that

 

      reporting.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I just wanted to mention one

 

      related, but not quite on-point matter.  We talked

 

      yesterday about concern that the studies that had

 

      been done to gain exclusivity might have been not

 

      as good as we would like.

 

                We weren't particularly talking about the

 

      design of the studies, which we think is okay, but

 

      let's say the approach to them.  Maybe there was

 

      too much of a rush, and so on.  If we were to put

 

      out a written request now, it would be one that

 

      required a third arm to the study, namely, a Prozac

 

      arm, because we know that Prozac can be shown to be

 

      effective.

 

                So, the study wouldn't count unless it had

 

      been able to show that it had what we call "assay

 

      sensitivity," the ability to tell effective drugs

 

                                                                40

 

      from ineffective drugs. We couldn't do that before

 

      because there wasn't anything at the time we wrote

 

      those requests that was known to be showable in

 

      children, but now there is.  There is three studies

 

      that all seem to show something.

 

                So, we should have much better information

 

      about what the pediatric population does in future

 

      requests.  That doesn't help the present

 

      discussion.

 

                DR. MURPHY:  I wanted to address that

 

      issue again, too, because I think I want the

 

      committee to be very clear on the fact that the

 

      Agency tells the company very clearly the type of

 

      studies that need to be done.

 

                We do give them, you know, a broader

 

      picture of the number of patients.  We tell them

 

      what we know will be the minimum, and, in general,

 

      I think Tom would agree that most of these studies

 

      have come in with the numbers in each arm that we

 

      have seen in other studies where they have shown

 

      effectiveness.

 

                So, the point here being that we do have

 

                                                                41

 

      control over the types of trials that are done, the

 

      number of patients, and the monitoring.  However,

 

      because there is a template up on your web that

 

      basically tells you what we ask for in depression

 

      trials.

 

                When you look at what the safety is, as

 

      has been pointed out many times, these trials were

 

      not set up to answer that question.  So, I think it

 

      is those kinds of issues that we would like to hear

 

      more about today.  As Dr. Temple said, it is how

 

      better to do these trials in the future.

 

                Thank you.

 

                DR. GOODMAN:  Thanks for that statements,

 

      Dianne. I just want to make sure I understand it

 

      completely.

 

                I think what you are saying, that if the

 

      conditions had been different at the time, that is,

 

      that the drug company was required to show, not

 

      only have a study, but a study that was positive.

 

      Then, the design would not have been any different,

 

      the sample size would not have been any different

 

      under those circumstances than the ones that

 

                                                                42

 

      existed at the time.

 

                DR. MURPHY:  I think what we are saying,

 

      that for the trials that we designed, they were the

 

      same for the one that did show some effect, which

 

      is Prozac, as those that did not, and that what we

 

      don't know is if a company is putting a trial

 

      together, and let's say we said that they had to

 

      have 300 patients to get their exclusivity, but for

 

      other reasons they really wanted this product

 

      approved, and they felt the enrollment was not

 

      going the way that they needed, would there be some

 

      other push within that company to then go out and

 

      get more patients, so that their enrollment would

 

      be better versus an exclusivity where all they had

 

      to do was meet that criteria.

 

                I am making that number up.  I think the

 

      issues that people were trying to get at is that is

 

      there a difference that affects behavior when you

 

      just know you have to do certain things versus you

 

      have another goal, which may be approval.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  The requirement for a third

 

                                                                43

 

      arm in evidence of assay sensitivity leaves it up

 

      to the company to decide how they are going to do a

 

      successful study.  They can look at the available

 

      data on Prozac and say, oh, here is the number I

 

      need, here is the kind of patients I need.  That

 

      succeeded in those three trials.

 

                They would then know that the trial would

 

      have to be one that can show the difference between

 

      Prozac and placebo.  That doesn't mean their drug

 

      has to show a difference between drug and placebo.

 

                That would be determined by the results,

 

      and there is no obligation that the drug be

 

      successful, but we would at least know we had a

 

      study that was capable of detecting effective drugs

 

      and distinguishing effective drugs from ineffective

 

      drugs.

 

                That would then become a requirement for

 

      meeting the terms of the written request because

 

      they would have to show that they had an adequate

 

      study.  Before there was an effective drug, there

 

      was no way to do that.  You couldn't tell whether

 

      the study was a good study or not.

 

                                                                44

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  If I could go back and

 

      address the question of what would the hypothesis

 

      be for long term, certainly, in the absence of

 

      data, there is some degree of speculation.  I do

 

      have a question directly to the FDA.  Is it okay if

 

      I respond?

 

                I think the number one hypothesis would be

 

      in the short run when you have depressed patients

 

      who are not yet stabilized, you may see an

 

      increased risk, and you do see certainly in this

 

      population an increased risk of suicidality.

 

                I imagine that what we would see with

 

      longer term data is a substantial decrease in

 

      suicidality over time, and that is what we are

 

      inferring from the cohort and the epidemiologic

 

      data.  I think that clinically makes sense, as well

 

      as mechanistically makes sense.

 

                The question for the FDA, can you give us

 

      a sense, I mean do we feel confident that we

 

      actually have all the available studies now in both

 

      children, adolescents, as well as in adults, and

 

                                                                45

 

      what is the FDA policy on requiring review of those

 

      studies including negative studies, when do they

 

      come to you and when do they become publicly

 

      available?

 

                DR. TEMPLE:  Well, let me start, others

 

      can comment.  When you submit to us an application

 

      to change the labeling, to add a claim, say, for

 

      pediatric use, you are clearly obliged under the

 

      law to provide every study, successful ones,

 

      unsuccessful ones, things that were interrupted,

 

      and so on.

 

                As far as we know, we are getting all

 

      those studies.  Of course, if there were something

 

      that were done that we didn't know about, well,

 

      then, we wouldn't know about it, but as far as we

 

      know, we are getting them all.

 

                So, most of the pediatric submissions to

 

      us were associated with labeling requests or

 

      something like that, so as far as we know, we have

 

      all those data.

 

                Dianne can tell you what is required under

 

      the best BPCA, and I think there, too, they have to

 

                                                                46

 

      provide them.  We have no rule that affects whether

 

      people have to publish results.  Congress is

 

      considering that, so are the journals and everybody

 

      is talking about that.

 

                Under BPCA, however, when we grant

 

      exclusivity, we provide summarized results, and we

 

      have done that for the drugs where the written

 

      requests were written after the BPCA, and we have

 

      gone back and asked the companies for permission to

 

      summarize our analyses for all of the others where

 

      it wasn't totally clear whether we could do it or

 

      not.

 

                So, the summarized result, that is not the

 

      same as a complete study report, the summarized

 

      results are now available publicly on all of those.

 

      I am sure between PhRMA's commitment to provide a

 

      registry between the journals insistence that they

 

      will get a registry, between congressional

 

      interest, I am quite confident that there will be a

 

      change in the way things get published.

 

                DR. MURPHY:  The only thing that I could

 

      add to that is that for the committee, for the

 

                                                                47

 

      routine practice within FDA, if a company submits

 

      an application, we review it, the studies are

 

      negative, there is no public acknowledgment of that

 

      unless the company for some reason wants to make

 

      that knowledge public.  We are not allowed to

 

      comment on that.

 

                Now, under BPCA, it said, it has a

 

      disclosure section that says you, FDA, will

 

      publish, as Dr. Temple is referring to, the

 

      summaries, the medical and pharmacology summaries

 

      up on the web--make them public, and actually, we

 

      have chosen to do that on the web--and we have done

 

      that.

 

                One of the issues that has happened is

 

      that between the enactment of the new legislation

 

      and the old legislation, legally, things were

 

      considered issues under the old legislation, so

 

      even though the studies came in, we had to reissue

 

      all those written requests to be able to say they

 

      now were subject to this new mandate.

 

                So, what again Dr. Temple was telling you

 

      is that unfortunately, many of the antidepressants

 

                                                                48

 

      came in, in that period when we had not yet issued

 

      that letter, but despite that, we have asked the

 

      sponsors to allow us to put those summaries up, and

 

      they have given permission to do so.

 

                That is why yesterday we said up on the

 

      web now are the summaries.  Again, this is not the

 

      data.  There is variations in, you know, some

 

      medical officers will put in more information than

 

      others in how much data is in these summaries, but

 

      they are up now, publicly available.

 

                DR. MARANGELL:  Is that true for adults,

 

      as well?

 

                DR. MURPHY:  No, adults are still under

 

      the same standard.  In other words, if the study is

 

      negative, we don't talk about it.

 

                DR. MARANGELL:  So, as an example, if an

 

      antidepressant manufacturer did a study in a new

 

      indication for a drug that is currently available,

 

      found increased risks of suicidality, no one would

 

      be under any obligation to make that public?

 

                DR. MURPHY:  That is a different issue.

 

                DR. MARANGELL:  But that is the question.

 

                                                                49

 

                DR. MURPHY:  The issue is safety, and the

 

      Agency always has the ability to make public safety

 

      issues that arise.

 

                Bob, do you want to say anything else

 

      about that?

 

                DR. TEMPLE:  We consider, for example, if

 

      someone with an antidepressant comes in for, I

 

      don't know, obsessive compulsive disease, and we

 

      don't buy it, we do not make those data available,

 

      they are considered confidential commercial

 

      information.  Obviously, a lot of the people, a lot

 

      of the public doesn't like that approach.  We think

 

      that is what we are required to do.  I can't

 

      comment on that, I am not the lawyer here.

 

                However, companies have a separate

 

      obligation for drugs that are marketed to report

 

      serious and unexpected, and any serious adverse

 

      reactions to us, and to do so promptly.  A finding

 

      of increased suicidality where that was not known,

 

      clearly meets that test, and they would be obliged

 

      to report it to us.  If we then thought that was

 

      true, we would add it to the label or do whatever

 

                                                                50

 

      we are supposed to do.

 

                So, safety data meets a different

 

      standard.  A new carcinogenicity study or

 

      something, those do have to be reported to us.

 

                Other studies have to be reported in the

 

      annual report, but they are not necessarily

 

      reported in detail, and not that much is

 

      necessarily made of them, and they do not

 

      necessarily become public.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  Yes, the serious safety

 

      issue would have to be reported while the trial is

 

      ongoing to you, right?

 

                DR. TEMPLE:  Well, if it arises from a

 

      trial, it has to be.  Actually, the requirements

 

      for reporting serious unexpected events in a trial

 

      are more or less identical to the requirements

 

      before a drug is marketed.  They have to be

 

      reported to us within 7 or 15 days.

 

                A finding from an epidemiologic study,

 

      there is some judgment involved in whether that

 

      represents the kind of thing that has to be

 

                                                                51

 

      reported promptly, but they basically do.

 

                DR. KATZ:  There is also some judgment

 

      involved in whether or not an event is considered

 

      to be unexpected.  So, for example, suicide in a

 

      study of patients who are at risk anyway might not

 

      be reported to us in real-time, because it might be

 

      considered to be expected, the blind is still

 

      intact, you don't know if it's drug or placebo if

 

      it is in the context of a controlled trial.

 

                Afterwards, though, when the trial is done

 

      and analyzed, and it turns out that there is an

 

      increased incidence on drug compared to placebo,

 

      that is something we would find out about.

 

                DR. GOODMAN:  Go ahead, Dr. Pollock.

 

                DR. POLLOCK:  I actually wanted to explore

 

      your thinking a little bit about the recommendation

 

      for a maintenance trial.  I guess there are a

 

      couple of things. One is if there is this acute

 

      toxicity that we are concerned about, clearly, it

 

      doesn't address that because you are dealing with

 

      the children or the adolescents who have actually

 

      responded, and then are withdrawn.

 

                                                                52

 

                But I wondered if there was implicit in

 

      your request for that, a concern that still that

 

      the shorter half-life SSRIs seem to be, maybe not

 

      statistically, but certainly qualitatively more at

 

      risk in causing this phenomenon.

 

                I was taking that as implicit perhaps in

 

      your suggestion, maybe I am over-interpreting it,

 

      but is there a belief that somehow--I mean it just

 

      seems more than coincidence that signals seem a

 

      little bit higher.

 

                I know it has now emerged with Prozac, but

 

      certainly, Effexor, venlafaxine stands out at one

 

      end, then followed by paroxetine, and if there was

 

      kind of an implicit question that you were asking,

 

      assuming that people are still using after we are

 

      finished, you know, those medications, that you can

 

      require that those manufacturers actually conduct a

 

      serious maintenance trial as part of you were

 

      saying your Phase IV regulatory requirement.

 

                DR. LAUGHREN:  We certainly, you know,

 

      until we saw the TADS data, were entertaining the

 

      notion that discontinuation might be one

 

                                                                53

 

      explanation for the bigger signal, the apparent

 

      signal that we are seeing with Paxil and Effexor.

 

                The TADS finding certainly challenges that

 

      notion as a unitary explanation, since that is the

 

      single trial among the 24 that, by itself, has a

 

      statistically significant finding for that signal.

 

      That doesn't mean that the other explanation isn't

 

      possible.  I mean this could be a much more complex

 

      situation than one might seem at first glance.

 

                But a maintenance trial is not going to

 

      answer all those questions.  I mean a maintenance

 

      trial is only going to answer the question of

 

      longer term benefit, but the reality is that many

 

      clinicians, despite these concerns, are probably

 

      going to continue to use these drugs, and we have a

 

      dearth of information about what the longer term

 

      benefits are.  The maintenance trial is one way, I

 

      think, of getting at that.

 

                Now, there is this issue of how to

 

      interpret emerging symptoms in that setting, you

 

      know, when you take patients off the drug.  Of

 

      course, the drugs like Paxil and Effexor, that are

 

                                                                54

 

      known to have a stronger signal for

 

      discontinuation, obviously are a challenge in doing

 

      that kind of trial, but I think that one could, as

 

      one does in clinical practice, taper those patients

 

      to try and address that, and then look for what

 

      would be considered for relapse.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  There is another reason to do

 

      randomized withdrawal studies.  As everybody knows,

 

      in adults, the failure rate for conventional

 

      clinical trials of the acute episode is about 50

 

      percent.  That is, half the trials can't tell drug

 

      from placebo, and that is true even when you

 

      include a third arm of a drug that is known to

 

      work.  That appears to be the nature of the beast.

 

                Nobody really has a good explanation

 

      because if they did, they would fix it, but we at

 

      least think it has something to do with the

 

      environment and the discussions that go on even

 

      informally, even if it is not planned as part of

 

      the treatment.

 

                In the randomized withdrawal setting, the

 

                                                                55

 

      success rate for drugs that are known to work is

 

      nearly 100 percent. Very few of those trials ever

 

      fail.

 

                There are at least two reasons.  One, only

 

      people who seem to be doing well are in the trial,

 

      so they are enriched with a responder population.

 

      You can make of that what you will.

 

                The other possibility, though, is that the

 

      environmental things that help people get better

 

      aren't really there, they are just out living in

 

      the community, there is nothing nurturing about it.

 

      They are just back in their usual environment.

 

                So, one of the attractiveness of these is

 

      to find out whether the drugs actually provide some

 

      benefit, even in people who seem to be doing well

 

      on them, which seems an important question here.  I

 

      mean, as Tom has pointed out repeatedly, the

 

      failure of most of the drugs to show effectiveness

 

      doesn't mean they don't work.  On the other hand,

 

      we don't have evidence that they do work, and that

 

      is not irrelevant either.

 

                A good way to show that, if they do, is

 

                                                                56

 

      the randomized withdrawal study.  At least that has

 

      been the history in adults, so there is a lot of

 

      attractiveness to it.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  Thank you.  I have two

 

      questions.               The first one is for Dr.

 

      Murphy and Dr. Temple, and the second for Dr.

 

      Laughren.  The first question addresses the

 

      exclusivity issue.  I feel like in this case, we

 

      bypass the Phase I/Phase II stages that we would

 

      normally go through with new drugs, so we never did

 

      do the pharmacokinetic/pharmacodynamic dose finding

 

      in children that we would have done had these been

 

      new drugs.

 

                I wondered, I probably should know this,

 

      but could either of you explain, when we offer

 

      exclusivity with a new drug, if it is a new drug to

 

      children, do we require those studies, or do we

 

      not?  I am sure it is not that straightforward.

 

                DR. MURPHY:  We did required

 

      pharmacokinetic studies.  Actually, on the

 

      template, we outline three types of studies.  They

 

                                                                57

 

      have to do two randomized, double-blind,

 

      placebo-controlled, acute treatment trials with

 

      recommendation at six to eight weeks for safety and

 

      efficacy.  They also are to do a pharmacokinetic

 

      study to provide information pertinent to dosing of

 

      study drug, and they are to do a safety study.

 

                So, all of those were asked for.  Now, if

 

      you are asking do we go back and demand redoing

 

      dose finding again in these, no, they were not

 

      worded that way.  It was said that the PK study

 

      could be a traditional PK or, alternatively, a pop

 

      PK, and actually, I don't think that the study had

 

      any other information that would have, in essence,

 

      told the company that they needed to redo the dose

 

      finding, if that answers your question.

 

                DR. CHESNEY:  So, do we have dose

 

      information on all of these drugs?  Do we know what

 

      the usual ranges are, and what excessive ranges

 

      are, all those things?

 

                DR. GOODMAN:  Go ahead, Dr. Katz.

 

                DR. KATZ:  I think Tom mentioned this in

 

      one of his slides yesterday.  The written requests

 

                                                                58

 

      that we issue now are very different from the

 

      written requests we issued that probably generated

 

      most of the trials that we are talking about here

 

      yesterday and today.

 

                As Dianne pointed out, for example, in

 

      pharmacokinetics, we gave sponsors the opportunity

 

      to generate the kinetics in kids based on so-called

 

      population pharmacokinetic analyses, which is to

 

      say from data generated in the controlled trials.

 

                So, it was sort of after the fact.  It was

 

      just what is the kinetics of the doses you happen

 

      to give in the trials.

 

                In the earlier written requests, it was

 

      sort of the pediatric drug development was sort of

 

      tacked onto the adults, in other words, when the

 

      trials were designed even, the treatment effect

 

      size, for example, was used to calculate sample

 

      size was taken from the treatment effect size seen

 

      in adults.  We had no information, even preliminary

 

      information in kids.

 

                So, we didn't have a lot of preliminary

 

      information in those days that could inform

 

                                                                59

 

      adequate trial design in this population, in this

 

      setting.

 

                Nowadays, we ask for different things.  We

 

      ask for formal PK, so we can learn before the

 

      definitive trial design, what the kinetics are,

 

      what doses give rise to what plasma levels.  We ask

 

      for dose finding studies, so we can determine

 

      before we design the definitive trials what the

 

      tolerated dose range is.

 

                So, the written requests are much

 

      different now than they were at the time that the

 

      requests are generated, these data were written.

 

                DR. MURPHY:  Just to reinforce that is

 

      that these were some of the earliest written

 

      requests that went out, so they really, as has been

 

      stated, and I think we tried to say this earlier

 

      on, we are learning.

 

                I mean because of the lack of prior

 

      research and some fundamental scientific questions

 

      haven't been answered, we are learning from the

 

      trials that we have now about how to do a better

 

      job on designing some of these trials, but these

 

                                                                60

 

      were some of the very earliest ones that were

 

      issued.

 

                DR. CHESNEY:  Dr. Temple, did you want to

 

      comment on that?

 

                DR. TEMPLE:  Well, I just wanted to say

 

      there isn't any pharmacodynamic measure to allow

 

      you to do what is called PK/PD other than

 

      effectiveness itself.  In a lot of cardiovascular

 

      settings, there is at least something you think

 

      relates to the desired effects, so you can do

 

      relatively short-term studies and get a PK/PD

 

      relationship.

 

                Here, your only way to do it is to insist

 

      that every drug, every study be a dose response

 

      study, which is of considerable difficulty.  We

 

      have trouble getting really good data even in

 

      adults actually given the sample sizes involved,

 

      but there isn't any measure yet.  Maybe one of

 

      these days there will be an MRI measurement or

 

      something, but not yet.

 

                DR. CHESNEY:  Well, I don't want to

 

      overstay my welcome, and I do have a question for

 

                                                                61

 

      Dr. Laughren, but one does wonder about some of

 

      these children who didn't even express ideation and

 

      just suddenly, very early on, if they didn't have

 

      excessive levels.  I guess that is one issue I was

 

      getting to.

 

                Dr. Laughren, I wanted to come back to the

 

      point Dr. Pine was making.  I thought Dr.

 

      Reisinger's point in the open session yesterday was

 

      a very interesting one, which is that you would

 

      have to undergo some kind of computer-based

 

      learning program or some kind of program that

 

      authorized you to prescribe psychoactive drugs.

 

                Certainly, we have to do computer-based

 

      CBLs for all kinds of things in our hospitals and

 

      in other areas nowadays.  That had a real

 

      attraction to me, and I guess the question is what

 

      kind of authority does the FDA have in an area like

 

      that, can you say that anybody that prescribes

 

      SSRIs must do a computer-based learning program on

 

      line, or is that something that the professional

 

      societies take on?

 

                You offered several options, black boxes,

 

                                                                62

 

      revised label warning, but is this a potential

 

      option?

 

                DR. TEMPLE:  We can certainly recommend

 

      things like that.  Every labeling for a cancer drug

 

      says that this should only be used by people who

 

      are trained in oncology. That comes with no

 

      enforcement on our part except that people may be

 

      anxious about the consequences if they don't have

 

      that training.

 

                A labeling recommendation is certainly a

 

      possibility.  A step further to limit the drugs to

 

      people who have been given that way, those are very

 

      iffy questions, and it is not clear whether we can,

 

      in fact, do that.  There would have to be a debate

 

      about it.

 

                There are some examples of fairly

 

      interventionist activities.  As you all know, you

 

      can't get clozapine unless you have a white blood

 

      count, so no blood, no drug.

 

                There are not a whole lot of other

 

      examples like that, but there are other cases where

 

      patients must be given a form that lists what some

 

                                                                63

 

      of the adverse effects might be, and things like

 

      that.  You have to weigh the risk you are concerned

 

      about with the burdensomeness to the community and

 

      to the medical profession of those kinds of

 

      interventions.

 

                Putting something in labeling about what

 

      you should know doesn't carry those kinds of

 

      concerns, so if something sensible, suggesting that

 

      people ought to be trained in a certain way seemed

 

      like a reasonable thing, we could certainly

 

      consider that.

 

                DR. TRONTELL:  I would just like to add on

 

      to Dr. Temple's comments, because the FDA regulates

 

      drugs, but doesn't regulate the practice of

 

      medicine, and we walk a fine line in terms of

 

      dealing with some drug products where we may feel,

 

      as with clozapine, that only very tight controls on

 

      prescribing and dispensing and use of the product

 

      are allowed.

 

                There are a very small handful of drugs,

 

      they tend to be the exception rather than the rule,

 

      where training has been required as a condition of

 

                                                                64

 

      approval.  One product in particular is the drug

 

      product dofetilide, where, in fact, training is

 

      required for pharmacists or clinicians.  There is a

 

      highly structured way in which that product can be

 

      used.

 

                Again, those have tended to be reserved

 

      for situations where we feel the drug cannot be

 

      safely used without that very high level of

 

      precaution.  It is extremely difficult to put those

 

      in place for products that have already been

 

      marketed and used by professionals.

 

                DR. CHESNEY:  The public sees your role I

 

      think in a much broader perspective, as we heard

 

      yesterday, and I think that is something that is

 

      useful to clarify as to where your limits are.  You

 

      mentioned there is a fine line, and I think that is

 

      what we are all looking for, is where does your

 

      authority end and that of prescribing physicians

 

      begin, I guess in a sense.

 

                DR. TRONTELL:  I don't think we yet have

 

      an answer.  I think we always have the authority of

 

      our agency and hopefully, our ability to persuade

 

                                                                65

 

      individuals, but I think that the actual legal

 

      authority to do some of these is a matter of debate

 

      within and outside of the agency.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  I would like to return to the

 

      topic of the incentives on the part of industry to

 

      perform well-conducted trials.

 

                There has been a lot of discussion about

 

      the evolution of the written request and about the

 

      improvement with three-arm studies and changes in

 

      the ability to request that, but my understanding,

 

      I am interested to know if this is accurate, is

 

      that there is still two potential linkages that

 

      don't exist that might decrease the incentive to do

 

      a well-conducted study, and that is, absent safety

 

      concerns, there is no tie to putting any efficacy

 

      information in labeling, so that they receive

 

      exclusivity if a labeling change occurs.

 

                Second, is that there is no link of

 

      exclusivity to a well-conducted study unless that

 

      has changed with written request, since I read them

 

      on the current web site, there is one asthma study

 

                                                                66

 

      where there was members of the drug group that had

 

      no drug level, members of the placebo group that

 

      had measurable drug levels, and the FDA concluded

 

      that the data was uninterpretable, but

 

      nevertheless, exclusivity was granted.

 

                I am wondering, is that a problem with the

 

      written request that is now fixed, or is there

 

      other solutions that would need to be put into

 

      place, such as legislation, to address those two,

 

      what I perceive as gaps.

 

                DR. MURPHY:  I think there was significant

 

      discussion about how exclusivity should work,

 

      should it be only if the product is approved.  I

 

      was not privy to those discussions, but I know they

 

      occurred.

 

                The reason for why it was put in place the

 

      way it is, I can't give you, Dr. Nelson, but I can

 

      tell you that one of the explanations I have heard

 

      is that there was such little data, and FDA was

 

      given the authority to define the trials, so again,

 

      as you have heard, we would like to improve, and we

 

      know we have to learn from what trials we have,

 

                                                                67

 

      that by providing FDA the authority to define the

 

      trials, that they hope that the trials would be,

 

      you know, of the best that they could be, and that,

 

      therefore, we would learn from the trials even they

 

      were failed, because that is important information,

 

      failing is important.

 

                So, I guess what you would say, you are

 

      asking if, and that is in a number of our labels,

 

      and that is a whole other discussion, but in

 

      situations, you know, we know that is the only

 

      study we are going to get and this is it, failing

 

      is put, that they failed to show effectiveness has

 

      been put in the label in a number of situations,

 

      and certain dosing or safety information.

 

                As I said, about a fourth of the time, we

 

      are describing, even irrespective of whether the

 

      study is positive or negative, we are finding

 

      safety signals, you know, important dosing

 

      information, and we are able to put that

 

      information in a label.

 

                The intent is that the information that is

 

      obtained, whether the product is proven to be

 

                                                                68

 

      effective or not is important, and that safety

 

      information, et cetera, would be obtained.

 

                So, that is the best explanation I can

 

      give you as to why it is set up the way it is right

 

      now.

 

                DR. NELSON:  I understand, but let me

 

      focus my question, I guess.  Right now the efficacy

 

      or lack of efficacy data is not in the existing

 

      labeling that we are discussing, so, for example,

 

      just to pick one, paroxetine, there is five

 

      studies, and the pediatric use just says it has not

 

      been established.

 

                Although that is a true statement, it is a

 

      bit misleading because many people interpret that

 

      to mean the studies hadn't been done.

 

                The other question is you could ask them

 

      to do a three-arm active control study, but if they

 

      do it badly, do they still get the money?  Even if

 

      they have done it, if they do it badly, do they

 

      still get the money?

 

                DR. GOODMAN:  Dr. Temple wants to respond.

 

                DR. TEMPLE:  If the written request says

 

                                                                69

 

      you need to do a three-arm study and need to show

 

      that the trial has assay sensitivity, that is, the

 

      ability to distinguish active drugs from inactive

 

      drugs, and the Prozac arm doesn't beat placebo,

 

      then, they would have failed to meet the

 

      requirement of the written request.

 

                We couldn't do that before, as I said,

 

      because we didn't have a known active control, so

 

      we wouldn't have known what to say.  So, in that

 

      case, the incentive to do a proper study becomes

 

      quite clear.  If they don't do a proper study, and

 

      succeed in showing that, they would not get

 

      exclusivity.

 

                In other cases, we have insisted that the

 

      variance be such that for, say, a blood pressure

 

      drug, an effect size of 3 or 4 millimeters of

 

      mercury could be detected, so if the whole thing is

 

      done sloppily and they could not have detected such

 

      a thing, then, they would not get exclusivity.

 

                Some of the other things, however, that

 

      you mentioned, don't have an obvious remedy.  I

 

      mean I guess following the example you said, we

 

                                                                70

 

      could say, oh, by the way, people should have blood

 

      levels showing that they took the drug.  Well, we

 

      hadn't been smart enough to think of that, and

 

      maybe that is something we should be adding, that

 

      is, some kind of compliance check.

 

                That, I don't think has been part of

 

      written requests to date.  That doesn't mean it

 

      couldn't be.  The test that Congress imposed is

 

      that if you comply with the terms of the written

 

      request, you get exclusivity.  That means if we

 

      weren't smart enough to ask a question, that is not

 

      considered their fault, and they are supposed to

 

      get it.

 

                DR. MURPHY:  And we have denied

 

      exclusivity where we thought the trials were done

 

      sloppily, and actually, sometimes when the sponsor

 

      said, well, we know you asked for this, but we

 

      didn't think it was correct to keep going, so we

 

      didn't do this for some reason, and we said, no,

 

      you should have come in and talked to us about why

 

      you weren't going to do it, you didn't do it, we

 

      told you, you need to do it, sorry, you don't get

 

                                                                71

 

      it.

 

                So, what I guess we are trying to say is

 

      if it's really sloppy, and they don't do what we

 

      tell them, we deny them exclusivity.  The problem I

 

      think we are dealing with here is that we all are

 

      learning how to better do the trials, and your

 

      other question about whether that should go in the

 

      label, the negative information should go in the

 

      label, is a whole other discussion.

 

                DR. GOODMAN:  I have a list of seven other

 

      committee members who wish to speak.  After we give

 

      them that opportunity, I am going to ask Dr.

 

      Wysowski to come up to the podium.  We had asked

 

      her to follow up on something from yesterday.  Is

 

      there somebody else that has a burning--we have one

 

      more and that is it--two more, that's it.

 

                Dr. Irwin.  His question has been

 

      answered.  Thank you.

 

                Dr. Rudorfer.

 

                DR. RUDORFER:  Yes, thank you.

 

                I would just like to revisit a couple of

 

      issues that concern me at the front end of these

 

                                                                72

 

      studies, and I recognize everyone from the FDA is

 

      pointing out that this is a learning process, on

 

      the other hand, we are faced with the dilemma of

 

      having these particular trials to deal with.

 

                The dosing question that was just

 

      discussed brings to mind a concern I have related

 

      to how the suicidal events we have been looking at

 

      were ascertained.

 

                As I understand it, for the most part,

 

      these were from adverse events questionnaires and

 

      surveys.  Is that correct?  I mean there was no

 

      particular suicidal scale?

 

                DR. LAUGHREN:  Well, all of these trials

 

      included standard depression rating instruments

 

      like HAM-D or CDRS, and so forth, and there is a

 

      suicide item in each of those instruments, and that

 

      is part of what we analyzed.

 

                But the problem is we don't really know

 

      how those were applied.  My guess is that most of

 

      the event data we are dealing with were spontaneous

 

      report or general questioning rather than specific

 

      ascertainment.

 

                                                                73

 

                That is really one of the areas that we

 

      are trying to explore with Columbia to try and work

 

      on a more specific instrument for improving

 

      ascertainment for suicidality, but no, in these

 

      trials, I don't think ascertainment was very

 

      specific.

 

                DR. RUDORFER:  My question, as we deal

 

      with these data, would be this.  I appreciate the

 

      very dedicated and elegant work that both the FDA

 

      and Columbia have applied to these findings.  The

 

      question I have relates to the issue of the active

 

      drug versus placebo groups.

 

                Since it sounds as if much of the data

 

      were spontaneous reports or I assume perhaps

 

      discussion between the raters and subjects, or the

 

      investigators and the subjects, I am wondering if

 

      part of this is not dependent on the assumption

 

      that the blind was kept intact throughout the

 

      studies, and I wonder if we have any measure of

 

      that or any sort of quality control on that issue.

 

                DR. LAUGHREN:  No, we have no idea of

 

      that.  That is typically not something that is

 

                                                                74

 

      really ascertained.  It is the assumption, but how

 

      would you check on that?

 

                DR. RUDORFER:  In some studies, patients

 

      and raters are asked at some point.  I mean here, I

 

      am just wondering if, in fact, if a patient

 

      volunteered that, for instance, they were

 

      experiencing some side effects, they come in, the

 

      rater asks how are you doing this week, and their

 

      first comment relates to GI distress or something

 

      that sounds like a side effect, if they simply

 

      don't get more attention, in other words, maybe

 

      there is more discussion, maybe there are more

 

      questions asked as opposed to a patient that comes

 

      in and say, gee, I am feeling pretty good, I don't

 

      seem to have any side effects.

 

                Again, that would not obviate the fact

 

      that if we find signals, then, the signals are

 

      present.  I guess I am just concerned about the

 

      active drug versus placebo difference.

 

                DR. GOODMAN:  Let me interject.  I don't

 

      think I am as concerned about the unblinding, but

 

      your question raises at least in my mind the

 

                                                                75

 

      possibility that in the data, is it possible that

 

      we would see other somatic symptoms, more side

 

      effects reported in those patients, who also

 

      reported suicidality than in the opposing group,

 

      was there any attempt in the data to look at

 

      whether there were any other--was any other

 

      increase of adverse experience outside the target

 

      symptoms of suicidality in those patients who

 

      reported suicidality, the reason being that if

 

      there was, that would suggest it was part of a

 

      larger behavioral syndrome that was being induced

 

      by the medication.

 

                DR. LAUGHREN:  Our analyses had to be

 

      limited by what we had in our database, and we had

 

      to design this database late last summer.  We

 

      didn't anticipate all of these questions.  As it

 

      was, the database we had was a very time-consuming

 

      process to put together.  It took a number of

 

      months to get it.

 

                They are all good questions, but we don't

 

      have all those answers, but I agree that

 

      ascertainment for suicidality was not optimal here.

 

                                                                76

 

                DR. GOODMAN:  But the question is at this

 

      point, could you go back to that same data and look

 

      to see if there is a higher rate of other adverse

 

      experiences reported in those patients who were

 

      also identified as experiencing or exhibiting

 

      suicidality.

 

                DR. LAUGHREN:  Not without designing

 

      another database and going back to the companies

 

      and waiting for a number of months, and I am not

 

      confident enough in the quality of the data we have

 

      here that that would justify that additional

 

      effort.

 

                I mean again, these are all good

 

      questions, but we are faced with making a decision

 

      at this point in time with what we have, and we are

 

      asking the committee's advice on what you think we

 

      can do now based on what we have done.

 

                DR. GOODMAN:  No, I agree with that, I

 

      understand that, but we were also asked what other

 

      advice we would give in terms of future research or

 

      studies or data that we would like to see.

 

                DR. TEMPLE:  Tom, we did look at the

 

                                                                77

 

      association with certain kinds of things, the

 

      activation syndrome, things like that, right?

 

                DR. LAUGHREN:  We included in our database

 

      two other symptoms, hostility and agitation based

 

      on the preferred terms that the companies used, and

 

      again, we haven't looked, I suspect that there is

 

      variability across different companies in what

 

      actually got subsumed under those two things.

 

                There are the only two other events, and

 

      we don't even have the timing for that.  All we

 

      have is an indication of whether or not, at some

 

      point during treatment, a patient experienced

 

      agitation or hostility.  We don't have all the

 

      other somatic kinds of things that you are alluding

 

      to.  That would mean going back and trying to

 

      create another database.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  Let me just mention one other

 

      thing that has come up briefly and that Dianne

 

      touched on, and that is inclusion of negative

 

      results in labeling.

 

                As Tom has explained at the previous

 

                                                                78

 

      meeting and now, as a general policy, we don't

 

      usually put in labeling the fact that a study

 

      hasn't worked, because we don't think that proves

 

      that it doesn't work.  It just means that that

 

      study failed.

 

                But we are actively thinking about that

 

      policy for the pediatric part, because the whole

 

      point of doing the studies was the possibility that

 

      adults and children are different, otherwise, you

 

      wouldn't even think about doing that whole program.

 

      All I can say is we are actively thinking about it.

 

                It is not an easy to thing to do, however,

 

      because what you would want to say could depend on

 

      how good you thought the study was, and then there

 

      is the conundrum of what do you do if there is one

 

      study that says yes and one study that says no.

 

      That is virtually somebody a claim, which we really

 

      wouldn't want to do if it wasn't merited.

 

                So, I am not going to suggest that this is

 

      easy, but we are reconsidering this whole thing,

 

      because the whole point of the Best Pharmaceuticals

 

      for Children Act is to find the data and see

 

                                                                79

 

      whether drugs work in children, and not putting

 

      anything in seems funny, so we are reconsidering

 

      that.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  Part of my question Dr.

 

      Chesney eloquently asked before, but I wonder if we

 

      can get access to the wording that you used for

 

      cancer drugs as perhaps a guide to us for our

 

      considerations.

 

                My other quick question, I think back to

 

      one of the FDA group is am I hearing you right that

 

      if you have a drug that has been shown to be

 

      efficacious in a particular indication, that all

 

      trials requested in the future require an arm that

 

      includes that drug?

 

                DR. TEMPLE:  I am not ready to say that

 

      one would always do that, there are other ways to

 

      try to assure quality, but in this setting, it is

 

      reasonable to assert that we need to know whether

 

      your trial was an adequate test of whether this

 

      drug worked, and the only way we know to be sure

 

      that it is an adequate test is to have an active

 

                                                                80

 

      control, and to have that active control be

 

      distinguishable from placebo.  Then, you know this

 

      is a trial capable of showing things.

 

                We have determined that our future written

 

      requests will include a requirement for a three-arm

 

      trial, because that's the only way we know to be

 

      sure that the trial is a trial that is capable of

 

      showing what the answer is, and we want to be sure

 

      we get the answer.

 

                This comes up in written requests all the

 

      time, how much assurance do you have to have and

 

      how do you gain that assurance that the trial is a

 

      useful trial, and the reason it comes up is the one

 

      that everyone has alluded to, we don't think people

 

      are deliberately trying to mess things up, but the

 

      incentives to do a really good trial are greater

 

      when you have to win.

 

                DR. PERRIN:  I am a little confused.  As a

 

      clinician, you know, typically, if I am looking at

 

      a new medication, I want to know that it is better

 

      than current therapy.  I mean all of us are really

 

      interested in that.

 

                                                                81

 

                There are a number of pediatric drug

 

      trials, not in the area of antidepressants that I

 

      am aware of, where new drugs come on the market,

 

      approved by the FDA, where there are only

 

      drug/placebo trials, and not trials comparing the

 

      new drug with currently approved FDA medications.

 

      That is where I am confused.

 

                DR. TEMPLE:  Good question.  There are two

 

      possible uses for having an active control.  One is

 

      where you want to compare the two therapies.  Now,

 

      to do that, you would need a very, very large

 

      study, because you would be interested in even

 

      modest differences.  That is not what we are

 

      talking about.

 

                We are talking about the use of the third

 

      arm to show something about trial quality.

 

      Actually, a third arm is extremely common in

 

      depression trials now, because if the trial fails

 

      to show that your drug is better than placebo,

 

      there are two possibilities.

 

                One is that your drug is no good, and the

 

      other is that the study was no good, and it is very

 

                                                                82

 

      important to somebody developing a drug to know

 

      which of those two things it is.

 

                If the trial shows that Prozac, say,

 

      works, and your drug doesn't, you get rid of the

 

      drug.  If the trials shows that neither Prozac nor

 

      your drug works, you do another study.  So, it is

 

      extremely important.  But the two purposes of the

 

      trials are quite different.

 

                To actually do a comparison and try to

 

      detect a small difference, you would need very,

 

      very large groups. That is an unusual thing for

 

      people to do, and usually, the drugs can't be

 

      distinguished.  It is very hard to do that.

 

                DR. GOODMAN:  Dr. Temple, I heard you say

 

      before, if I heard correctly, that incentives are

 

      different when you need to win.  Were you referring

 

      to the conditions of the six-month exclusivity

 

      arrangement, and if you were, if the incentives

 

      were different at that time, would you predict any

 

      difference in the design of those trials or the

 

      conduct of those trials?

 

                The reason, let me say, I think that many

 

                                                                83

 

      of us keep harping on this point, is not so much

 

      because we think that the suicidality data would

 

      have turned out differently. I think it is the

 

      absence of a benefit, the absence of efficacy that

 

      at least I am concerned about, because that is

 

      mostly what we have in assessing benefit or those

 

      trials, and we only have 3 out of 15 that are

 

      positive, so if there was something about the

 

      conditions in which those studies were designed or

 

      conducted that might have negatively impacted the

 

      outcome, I would like to know it.

 

                DR. TEMPLE:  Well, Russ and Tom need to

 

      respond, but we haven't seen anything in the design

 

      of those trials as written in protocols that makes

 

      them look any worse than any other trials.  They

 

      seem to have reasonable size, so there is nothing

 

      obvious.

 

                But, you know, this is an issue that comes

 

      up when you do so-called "non-inferiority" trials.

 

      The incentive, you know, the point of such trials

 

      show no difference between treatments, and as I

 

      have written repeatedly, that is not a good

 

                                                                84

 

      incentive to give people.

 

                It doesn't stimulate the kind of optimal

 

      behavior that you want, which is stimulated by the

 

      need to try to show a difference between

 

      treatments, and that is a problem here if you don't

 

      need to win, to gain exclusivity, and I don't

 

      disagree with the idea that you shouldn't need to

 

      win, the point is to get the data.  That is why the

 

      BPCA was done that way.

 

                On the other hand, you do want a good

 

      trial, and one way to guarantee that the trial is a

 

      good trial, however the drug comes out, is to be

 

      sure that it is capable of showing something we

 

      need to be true, namely, that Prozac seems to work.

 

                DR. KATZ:  Can I just add?  One thing you

 

      need to remember about studies done in response to

 

      written requests is that they are very time

 

      sensitive, or at least it's possible that they are

 

      time sensitive.

 

                What I mean by that is you only get

 

      exclusivity if your study reports, your supplements

 

      containing the data come in while you still have

 

                                                                85

 

      some residual patent life left or exclusivity left.

 

      So, they have to be done within a particular time

 

      frame.  In fact, the letters that we send, the

 

      written requests include a date by which the

 

      studies have to be submitted.

 

                So, in some cases, there is at least

 

      potentially motivation to do studies rapidly, so

 

      that they are done and study reports are written,

 

      and the supplement, which includes these data, are

 

      submitted in time, so that they can still get their

 

      exclusivity.

 

                So, one at least potential question that

 

      has been raised is enrollment so rapid or does it

 

      need to be so rapid into these trials that maybe

 

      not all the patients are adequately diagnosed, and

 

      maybe they have something other than depression.

 

                It is very, very difficult for us, if not

 

      impossible for us, to be able to independently

 

      corroborate diagnoses in something, in conditions

 

      like these, so we, of course, take it on faith that

 

      they got the right patients, but maybe, for

 

      example, because of time constraints, they didn't

 

                                                                86

 

      get the right patients, and that might contribute

 

      to a negative finding even if the drugs were

 

      effective in a true population.  So, that is one

 

      possibility.

 

                DR. GOODMAN:  I think that is a fair

 

      answer.  Anybody that wanted to comment

 

      specifically on that?  Dr. Marangell.

 

                DR. MARANGELL:  Are you aware, is there a

 

      greater proportion of non-academic sites in these

 

      trials?

 

                DR. MURPHY:  I don't know that we have

 

      looked at that.  I mean I know that there are

 

      definitely, in some of these studies, very, you

 

      know, academic sites that have been involved in

 

      numerous or actually well-known to us

 

      investigators.

 

                I do want to make one thing again.  One

 

      thing that every division within FDA is told, when

 

      writing their written requests, they are asked a

 

      number of questions - what is the public health

 

      benefit, what are the trials to get to that public

 

      health benefit, and you are not to take into

 

                                                                87

 

      consideration--and most of the time they don't even

 

      know because you would have to go into a lot of

 

      patent law--they don't know or are told to not pay

 

      any attention to when the patents expire or the

 

      exclusivity marking would go out, they must look at

 

      it only from what are the trials that they need to

 

      have done.

 

                Now, what is being told to you, though, is

 

      that--and we have written requests where the

 

      companies come back and say, well, that is not

 

      going to help us, because you put a date on here

 

      that it was due by 2007, and our patent expires in

 

      2005, and we have said, you know, we are sorry, we

 

      need these kind of trials.

 

                Now, would, in that situation, a company

 

      try to compress by getting more sites or, you know,

 

      whatever, would they try to do that trial in a

 

      different way?  Yes, possibly.

 

                I mean that is what we are trying to

 

      explain the balance between the way the process is

 

      set up, it is not to be driven by the time when the

 

      patents are expiring, the marketing exclusivity is

 

                                                                88

 

      expiring, the divisions are to determine what the

 

      studies are that are needed to the best of their

 

      knowledge at that time.  They are to design those

 

      studies to answer those questions.

 

                Do we try to be reasonable and say, gee,

 

      we would like a 10-year follow-up study, but we

 

      don't ask that for other--you know, we have to be

 

      reasonable within the realm of what we would

 

      normally ask for, for an approval product.

 

                Again, though, maybe we can be--we say we

 

      have to get this information because children grow

 

      and will go through a period where that might be

 

      effective.

 

                DR. GOODMAN:  Thank you, Dianne.

 

                DR. MURPHY:  So, you have to ask for

 

      additional information, you might not, for adults.

 

      I am trying to explain the process.

 

                DR. GOODMAN:  I will accept some questions

 

      out of order if they are on this specific topic.

 

                Dr. Rudorfer, I think  you had one.

 

                DR. RUDORFER:  I just wanted to follow up

 

      on Dr. Katz's comment about whether we are looking

 

                                                                89

 

      at the right patients, which was an issue we

 

      discussed some yesterday.

 

                Just one point that I want to follow up

 

      on.  It is clear that in young people who present

 

      with major depression, there is a disproportionate

 

      number who go on to develop bipolar disorder, and I

 

      think one concern that we expressed yesterday was

 

      that the trials are very inconsistent in that

 

      especially in terms of accounting for family

 

      history, it sounded as if in some trials, a subject

 

      could literally be brought to the clinic by a

 

      parent who has bipolar disorder, and yet the child

 

      could be included in the trial.

 

                I realize this question might be, as we

 

      said, a little out of the box.  I would think that

 

      if there is any way to encourage the companies to

 

      actually try to find some of these thousands of

 

      young people and see what has happened to them in

 

      the 5 or 10 years since they were in the study, it

 

      could be tremendously informative simply in seeing

 

      whose longitudinal course has played out as what we

 

      recognized in young adults as major depression, who

 

                                                                90

 

      developed bipolar disorder, who developed some

 

      other disorder, and go back and re-look at, for

 

      instance, those who after the fact are confirmed to

 

      have the diagnosis that we thought they did on

 

      inclusion.

 

                DR. GOODMAN:  Dr. Pfeffer.

 

                DR. PFEFFER:  Yes, I want to I guess

 

      continue on what Dr. Rudorfer is saying, because I

 

      think diagnosis is critical, and I think we can

 

      learn something about this that we have learned a

 

      little bit about depression in other realms, too,

 

      namely, that children are, in fact, different than

 

      adults.

 

                So, what appears to be adult depression

 

      and what appears to be childhood depression may, in

 

      fact, be quite different, so that perhaps a lack of

 

      efficacy in most of the studies tells us something

 

      about the nature of the developmental course, first

 

      of all.

 

                I agree with what you are saying about the

 

      potential for bipolar.  That is one issue that is

 

      crucial, I think, in terms of maybe the adverse

 

                                                                91

 

      response that children are having, but also if we

 

      think of the number who had some suicidal thinking,

 

      that also might be a subgroup of the children who

 

      are in these studies also.

 

                The other part that I want to mention is

 

      that when I gave that talk last meeting, I talked

 

      about the complexities about what looks like

 

      depression in children, and not only course and

 

      family history, but life event circumstances, and

 

      that has not been looked at.

 

                So, for example, children who might have

 

      been having immediate family turmoil and looked

 

      depressed, that is an issue that might have led to

 

      some resistance in response, for example.

 

                The other point I would like to make is

 

      that we hear from some of our childhood

 

      psychiatrist colleagues yesterday who advocate to

 

      not ban use of these drugs, because they do see

 

      efficacy, and it may very well be that in their

 

      practice, with very careful assessment, careful

 

      diagnosis, they are selecting the subgroup of

 

      youngsters who potentially could respond, and

 

                                                                92

 

      respond very, very well.

 

                So, I think the question of diagnosis is

 

      crucial, which means that in terms of the study

 

      design, in a way, who has the most reliability to

 

      make a diagnosis, and what kinds of questions

 

      really are being asked and what data is being

 

      collected that might help us even look at

 

      predictability of response, and I don't think we

 

      have that, such as life events, such as family

 

      history, such as perhaps other issues that we would

 

      need to come up with and understand.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Gorman.

 

                DR. GORMAN:  A lot of us keep saying that

 

      children are different, and I don't think it should

 

      come to us, then, as a surprise that children may

 

      respond differently to medicines than adults do.

 

                I think I would be more concerned about

 

      the efficacy of these trials if they were all

 

      unidirectional in the sense if they had all failed

 

      or they had all succeeded. I have heard nothing

 

      from the FDA to this point that says that the

 

                                                                93

 

      playing field has been tilted in any way since one

 

      of these drugs in this class, which may not

 

      actually be a class, but it seems like it might be

 

      a class, actually works for children in the bar

 

      that the FDA sets up.

 

                So, I am now going to address my single

 

      question to the rushing hypothesis.  After Monday

 

      Night Football last night, I like the rushing

 

      hypothesis.  There is one small question I have to

 

      ask.

 

                Prozac was the first mover in this field,

 

      therefore, I assumed it came to market first, and

 

      probably then had the least time before its patent

 

      extension.  Is that a safe statement?

 

                So, it came to market first.  Did it have

 

      the smallest amount of time?  It was the first to

 

      go off patent, yes or no?

 

                DR. TEMPLE:  I believe it was the first

 

      one to go off patent by a little bit.  It is off

 

      patent now, and only, I don't know, are any of the

 

      others off patent?  So, we know it was the first

 

      off patent, which happened sort of a year ago.

 

                                                                94

 

                DR. GORMAN:  So, that would run

 

      counterintuitive to the rushing hypothesis, because

 

      Prozac had to get there first, and therefore, seems

 

      to have had the least time and would be the most

 

      likely to be rushed to get labeling.

 

                DR. TEMPLE:  Some of the trials were done

 

      before this program even started, I think, and they

 

      were done a long time ago.

 

                DR. LAUGHREN:  One of the trials was done

 

      by Emslie several years before, and the company

 

      obtained the data and submitted those data as part

 

      of that supplement.  It was done in the early '90s,

 

      though.

 

                DR. KATZ:  Right.  The studies that we

 

      asked for in the written requests don't necessarily

 

      have to be done or initiated after the written

 

      request is written.

 

                If they have a study that is very old, but

 

      that meets the criteria that we put into the

 

      written request, they can use that, so they don't

 

      have to be done specifically in response to the

 

      written request, they have to meet the criteria

 

                                                                95

 

      that we lay out, and it can have been submitted to

 

      us either before the written request.

 

                But they could have done a study many,

 

      many years in advance before we even contemplated

 

      written requests.  If they met the criteria, they

 

      can submit it in response.

 

                DR. TEMPLE:  But, also, remember it's a

 

      hypothesis.  We don't know why those trials fail.

 

      It could be that children really don't respond.  I

 

      mean we don't know the actual answer.

 

                DR. GORMAN:  Well, I would love to be in

 

      the position where I can say something nice about

 

      the pharmaceutical industry, because it sometimes

 

      seems to happen so rarely, but if Lilly did the

 

      trials before there was the potential for financial

 

      gain, because all they were doing was looking for

 

      labeling in children without the congressionally

 

      mandated reward for that particular behavior, and

 

      therefore had these studies in place, maybe the

 

      rushing hypothesis fails, but there is another

 

      hypothesis that could be generated from that.

 

                DR. LAUGHREN:  Again, in fairness, the

 

                                                                96

 

      Emslie trial was funded by NIMH.  This was not

 

      sponsored by Lilly.  They went back and obtained

 

      the data, and they did subsequently an independent

 

      trial that also succeeded.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  I think Dr. Temple did a good

 

      job of explaining why, if you have an active

 

      treatment arm, the trial is likely to be of higher

 

      quality when asked to demonstrate that difference.

 

                I wonder if another approach to motivating

 

      high quality studies would be to require that in

 

      order to get the exclusivity, that the trial be

 

      written up in a way that passes some sort of peer

 

      review and be published.

 

                That way, even published on FDA web site,

 

      that way, if the trial is sloppy and finds the drug

 

      doesn't work, those results would not be buried,

 

      they would become public and that I think would

 

      provide some motivation to do a good job.

 

                I am a little troubled.  I wrote down a

 

      quote from Dr. Murphy.  It said, "If a study is

 

      negative, we don't talk about it."  I think if

 

                                                                97

 

      that's the case, then, there is a lot less

 

      motivation to do a really good job on the study.

 

      Why not require the studies be published, be

 

      written in a way that it is of sufficient quality

 

      that they can be interpreted, and then maybe the

 

      quality would improve.

 

                DR. MURPHY:  But for peds now, we do.

 

      That is the difference.  That statement was for

 

      adults.  For pediatric studies, well, I should say

 

      it is for pediatric studies that aren't done under

 

      exclusivity, but for pediatric studies done in

 

      response to these written requests, we now are

 

      mandated to make them public whether they are

 

      approved, they are not approved, or even if they

 

      are withdrawn.

 

                DR. TEMPLE:  But you are also talking

 

      about a level of detail in the presentation

 

      sufficient for people to really get into was it a

 

      high quality study, and things like that.

 

                DR. NEWMAN:  Why not?

 

                DR. TEMPLE: it is a fairly good question.

 

      We don't believe we have authority to insist that

 

                                                                98

 

      things be published.  We get full details, we get

 

      all the data.

 

                DR. NEWMAN:  But you could peer review,

 

      you could peer review them.  You could send them

 

      out and say is this something that is publishable,

 

      and have people at FDA, who I am sure are very good

 

      at that, say no, this gets an F, you know, this is

 

      not good enough, send it back, or you don't get the

 

      exclusivity.

 

                DR. TEMPLE:  Well, our reviews, when we

 

      approve something, you get on our web site the

 

      contents of our reviews, so you get to see what we

 

      thought of all of the studies.  If we do not

 

      approve, however, we don't believe we have

 

      authority to make those data public, so you don't

 

      get to see our reviews.  That is our legal

 

      interpretation of what confidential commercial

 

      information is, and I can't rebut it or comment on

 

      it.  It's a legal determination.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Just on that point, does the

 

      FDA now have the authority, if you wanted to, to

 

                                                                99

 

      put negative studies in the pediatric label, do you

 

      have the authority or does Congress have to do

 

      something for you to get the authority?

 

                DR. TEMPLE:  We have authority.  What I

 

      was saying before is--and we are, as I said,

 

      considering whether in the pediatric case, we

 

      should do that.  In other cases, we would, too, if

 

      we thought it was important to point out the

 

      negativity, and the negativity was a true bill.

 

                It is just the fact that if one study

 

      fails, doesn't necessarily say that something

 

      doesn't work, so we have been somewhat reluctant to

 

      just do that until it was convincing.

 

                But as Dianne said, we are actively

 

      thinking about amending that policy for the

 

      pediatric setting where the whole point of getting

 

      the studies done was to see how the drugs worked in

 

      children, for the very same things that they have

 

      been studied for in adults.

 

                It is a little different from novel use or

 

      something like that.  The BCPA calls for studies of

 

      the exact same things that have been studied in

 

                                                               100

 

      adults.

 

                DR. MURPHY:  And we are putting negative

 

      information in some of the labels already for other

 

      types of products, but because of the complexities

 

      that you have heard, it has been the policy for

 

      antidepressants for children not to do that at this

 

      point, but I think, as has been mentioned, it is

 

      being reconsidered.

 

                So, we have, and I have got all the labels

 

      here that we have done, we are putting that

 

      information in some of these labels.

 

                DR. POLLOCK:  For the new approvals.

 

                DR. MURPHY:  No.

 

                DR. TEMPLE:  For where we grant

 

      exclusivity.

 

                DR. MURPHY:  Right.  In other words, if a

 

      product comes in and doesn't work, we have put that

 

      information in some labels where we think it is

 

      very clear-cut, you know, eight more studies is not

 

      going to change this for whatever reason, and we

 

      put that in here.

 

                We have also put in information where it

 

                                                               101

 

      hasn't worked where there are safety issues

 

      involved, and we are not clear what those safety

 

      issues are, but we want to tell you about them.

 

      So, those are in the label, too, even when it

 

      wasn't approved for that indication.

 

                DR. GOODMAN:  Dr. Santana.

 

                DR. SANTANA:  I have a comment and then a

 

      question that really relates to a point that Dr.

 

      Chesney made about issues regarding the boundary of

 

      practice and FDA regulation.

 

                My comment is that there was some comment

 

      related to oncology and issues, how we deal with

 

      some prescription and safety issues in oncology,

 

      and I think we have to recognize that pediatric

 

      oncology is unique in this country and that most of

 

      the trials, even the exclusivity trials, of which I

 

      have participated in some in oncology, are really

 

      under the umbrella of research centers and academic

 

      centers. Very little pediatric oncology is done in

 

      the private practice.

 

                So, by force, you are now dealing with a

 

      group of individuals that are more specific and

 

                                                               102

 

      more geared up to looking at issues that

 

      potentially could be relevant, whereas, I think in

 

      the other pediatric arenas that we are talking

 

      about, that doesn't occur.

 

                So, I think it would be a misnomer to use

 

      pediatric oncology, maybe it should be the gold

 

      standard, but I think we need to recognize that it

 

      is kind of unique in the way it is practiced in

 

      this country.

 

                Having participated in some of the

 

      exclusivity oncology trials, I can tell you that

 

      they are at the same caliber and at the same

 

      rigorous structure as any of our other oncology

 

      trials are in the cooperative group setting, et

 

      cetera, et cetera.  So, that was just a comment to

 

      clarify the pediatric oncology issue.

 

                I want to get back to patients and

 

      practicing physicians, because we have been talking

 

      a lot about study design and how to analyze data.

 

      I want to get back to the issue of patients,

 

      parents, and practicing physicians, and this

 

      boundary of what the FDA can regulate and cannot

 

                                                               103

 

      regulate in terms of the practice of medicine.

 

                I was struck yesterday by many of the

 

      testimonies from parents and families, and

 

      actually, there was even a gentleman who showed a

 

      slide, in which his child was given the medication

 

      as a free sample.  I am not sure that all these

 

      whistles and alarms that we put in labels are

 

      really going to work unless somehow that practice

 

      stops for certain medications that we think

 

      potentially have a greater risk.

 

                I wanted the FDA to address the issue

 

      historically.  Is there any ruling that you guys

 

      can impose or potentially think about, about how

 

      these medications are given without prescriptions,

 

      that is, either free samples or in the marketing

 

      world, so you could comment on that.

 

                Secondly, does the FDA have any historical

 

      data on successful programs?  There was a mention

 

      that maybe a med guide to parents and families

 

      would be a way to address some of the safety issues

 

      and bring people to a better level of

 

      understanding.

 

                                                               104

 

                Can the FDA comment on any successful

 

      programs that they can point where this has truly

 

      worked?

 

                DR. TEMPLE:  Just on the free sample

 

      thing, my understanding, but I don't really know,

 

      was that a physician did use a free sample to, you

 

      know, like start the child out.  That is not

 

      without a prescription, it may not have been well

 

      done and may not have had adequate follow up, but I

 

      am not sure that it is the free sample that is

 

      involved, it is the lack of follow up that was

 

      described that seems like the problem.

 

                It is not easy to know how successful our

 

      various endeavors have been, and Anne Trontell may

 

      want to comment on that.  Some of them have effects

 

      that are not entirely what we wanted.  She

 

      mentioned the program on dofetilide.

 

                To start, dofetilide is a drug that is

 

      used to prevent recurrence of atrial fibrillation,

 

      but it is a drug that causes QT prolongation and

 

      Torsade de Pointes, and there is no doubt about it.

 

                The recommendation in labeling, and it is

 

                                                               105

 

      enforced by the need to give out various

 

      information requires that you come into a hospital

 

      or outpatient facility for a couple of days to see

 

      what your creatinine clearance is and to see

 

      whether you are a person who has QT prolongation to

 

      an excessive degree.

 

                Then, after that you can go out and be

 

      treated with it for long-term use in preventing

 

      atrial fibrillation.

 

                What appears to have occurred is that that

 

      is sufficiently difficult, so that people instead

 

      use sotalol, which doesn't have such a program, or

 

      quinidine, neither of which are an improvement of

 

      the situation.

 

                So, people can avoid some of these things

 

      if they are inconsistent across the drug classes,

 

      so you always worry about that.

 

                There is a very rigorous requirement for

 

      periodic measurement of liver tests with a drug

 

      called Bosentan, which is used for pulmonary

 

      hypertension, and although the drug was quite toxic

 

      when it was being developed, my most recent

 

                                                               106

 

      information is that we haven't had any fatal liver

 

      outcomes, perhaps a testimony to the fact that

 

      people are indeed following up these patients.

 

                Of course, this is a class of patients who

 

      are very sick and very closely watched.  You don't

 

      know if that is typical how we are going to do.

 

                Anne, you want to comment on some of the

 

      other programs.

 

                DR. TRONTELL:  Sure.  On the issue of

 

      sampling, first of all, I think in some instances,

 

      at the time of product approval, there have been

 

      informal agreements, but no FDA authority to

 

      restrict sampling exists to my knowledge, but there

 

      may be agreement, you know, certainly, we don't

 

      sample oncology drugs.  There are things that just

 

      don't happen.

 

                On the issue of what is a successful

 

      program, I think we struggle in the agency, because

 

      good evaluations have not been done on a standard

 

      basis.  We have the best information for those

 

      programs that are most restrictive, programs like

 

      clozapine or programs like the one for thalidomide

 

                                                               107

 

      to prevent pregnancy exposures.

 

                So, the available data to us to tell us

 

      what works tends to be only in those extreme cases

 

      where we have put, as Dr. Temple just described,

 

      for Bosentan, you know, very severe restrictions.

 

                If you are asking for specific information

 

      about medication guides, I think we have in the

 

      general literature evidence to suggest that good

 

      education certainly facilitates good behaviors, but

 

      I don't think we have any evidence yet that it

 

      guarantees that they do take place.

 

                So, if you had questions about the

 

      intermediate ones, I think for the most part, we

 

      don't have information about those specific

 

      educational programs or the reminder ones.  Not

 

      uncommonly, education is applied in the context of

 

      these very restrictive programs that I just

 

      described, and again, teasing out what the

 

      education alone does is very difficult.

 

                DR. GOODMAN:  Dr. Katz.

 

                DR. KATZ:  You are hearing the

 

      difficulties that we think we have with regard to

 

                                                               108

 

      imposing various sorts of restrictions although

 

      again, there are ways to do it although they may be

 

      very difficult to implement.

 

                But it occurs to me that it might be

 

      particular difficult in this case because the use

 

      we are contemplating in all but one case is off

 

      label, and I don't even know what the implications

 

      of that are.  Certainly, there are legal questions

 

      about what you can say and what you can restrict

 

      with regard to off-label use, and I don't think

 

      that we have thought through all the implications

 

      of that.

 

                DR. SANTANA:  So, as a follow up to that,

 

      since we last met in February and there was a

 

      recommendation to do something with the label that

 

      occurred and some warnings, has the Agency

 

      monitored the change in practice?

 

                I heard a number yesterday of 10 percent.

 

      That is prescriptions, but has that been rigorously

 

      looked at, that there was an impact of that

 

      modification that translated to something very

 

      tangible?

 

                                                               109

 

                DR. TRONTELL:  I will ask either Michael

 

      Evans or Judy Stafford from the Office of Drug

 

      Safety.  All we have really been able to monitor

 

      since the last advisory committee is volume of use,

 

      but they do have some information on how that has

 

      changed recently.

 

                DR. GOODMAN:  Ms. Griffith.

 

                MS. GRIFFITH:  I would just like to pursue

 

      this for a moment with respect to the patient and

 

      physician relationship.  When Dr. Chesney was

 

      proposing perhaps some sort of a computerized

 

      programming or education, or even with respect to

 

      these med guides, when Dr. Temple suggested that

 

      perhaps there would be, you know, a mechanism much

 

      like you have for other drugs, that the patient and

 

      practitioner would be signing a consent form

 

      outlining the risks and benefits, I want to

 

      understand the reason that you thought that that

 

      might be too great a deterrent to pursue, simply

 

      because from my perspective as patient rep and

 

      parent, it seems to me that in the course of any

 

      treatment process for any severe illness, which as

 

                                                               110

 

      we all understand depression is, you are often

 

      asked to look at the risks and to sign some

 

      statement to the effect that you understand what

 

      these risks are.

 

                You even have to do that if you get a shot

 

      of botox, not that I know, but it just strikes me

 

      you have put the parents now in the position of

 

      actually doing the risk-benefit analysis.  That is

 

      where we all are.

 

                If by providing the families with the

 

      statement that these risks are indeed serious, I

 

      think that what we heard yesterday was how little

 

      awareness there was on the part of the parents that

 

      these drugs could be lethal in certain cases.

 

                I am arguing for more information rather

 

      than less, not more restrictions, and I agree with

 

      the point that Dr. Santana made, that how often

 

      does a parent either open the box and read the

 

      information or understand it.

 

                So, if it is very clearly stated between

 

      the doctor and the patient or the parent, I think

 

      it goes a long way to satisfying the need to know

 

                                                               111

 

      for parents.

 

                DR. TEMPLE:  There are gradations of

 

      information, and we wrestle with how to do that

 

      without being an attempt to be informative, but not

 

      disruptive, so that, for example, a lot of drugs

 

      have what are called med guides.  These are patient

 

      labelings that are actually, under the law,

 

      supposed to be given out by the pharmacist.

 

                My own view is that if you don't make it

 

      part of the unit of use package, you might as well

 

      not bother, but in any case, we know that there are

 

      ways to get that information to patients either

 

      through the proper functioning of the pharmacy or

 

      by making it part of the package.

 

                An enormous additional step, which has

 

      been done in some cases, but, you know, thalidomide

 

      is a level of risk that is sort of in its own

 

      category, where there is a requirement that the

 

      patient and physician discuss all these matters.

 

      That is a very huge step, and what you might think

 

      is reasonable for thalidomide, something that is

 

      used infrequently, you might find more disruptive

 

                                                               112

 

      than you want or more difficult than you want for

 

      drugs that are much more widely used.

 

                As Russ pointed out, it is particularly

 

      tricky when the recommended use isn't even in the

 

      label.  How to write a med guide or something like

 

      that for something you are not really recommending

 

      and don't feel able to recommend yet, that may

 

      sound like a bureaucratic worry, but I think it's a

 

      serious worry.

 

                You don't want to warn people and

 

      simultaneously recommend a use that you don't think

 

      is recommendable, and any discussion like that is

 

      tantamount to recommending the use.  So, we will

 

      need to worry all of those things based on your

 

      conversation.

 

                MS. GRIFFITH:  Could I follow up?  I

 

      understand that and I understand that there are all

 

      sort of issues involved, liability on the part of

 

      the physician, but I am suggesting, from the naive

 

      perspective of the parent, I think of depression as

 

      every bit as serious as the use of thalidomide

 

      posing birth defect risks or, as Dr. Santana said,

 

                                                               113

 

      you know, the cancer example.  Parents need to be

 

      informed about those risks.

 

                I don't think that this is any different,

 

      frankly, and if it is an extraordinary measure to

 

      take, I think that it benefits both the

 

      practitioner and the patient parent.

 

                DR. TEMPLE:  For oncologic drugs, the

 

      label says you should be a properly trained

 

      oncologist.  There isn't anything in there that

 

      says what you need to discuss.  Patient med guides

 

      for oncologic drugs is by far the exception, I

 

      think because it is assumed that there always has

 

      to be such a conversation in the course of therapy.

 

                I guess what is being discussed is whether

 

      there is a common practice of having that kind of

 

      conversation in someone who is depressed, and

 

      obviously, we all think that there should be such a

 

      conversation.  The question is now to induce it and

 

      what to provide people to help them be sure they

 

      ask the right questions.

 

                DR. GOODMAN:  We have a representative

 

      from the Office of Drug Safety at the microphone. 

 

                                                               114

 

      Could you please state your name?

 

                MR. EVANS:  Michael Evans with the Office

 

      of Drug Safety.

 

                With regards to drug use, comparing the

 

      first six months of this year to the first six

 

      months of last year, the market rose with all ages

 

      about 7 percent.  Adolescents and children, in the

 

      first six months of the year, still comprised

 

      between 7 and 8 percent of that total.  So, they

 

      are still widely used in children.

 

                DR. GOODMAN:  How up to date is that data?

 

      There must be some sort of lag time, isn't there,

 

      between when the prescription--

 

                MR. EVANS:  It is according to IMS Health,

 

      and this is January through June is what we looked

 

      at.  This is outpatient prescription data, which

 

      comprises about 45 percent of all pharmacies in the

 

      country.

 

                DR. GOODMAN:  Let me make sure I

 

      understand.  You don't see any significant drop?

 

                MR. EVANS:  No.  I believe a woman

 

      mentioned yesterday that they saw a 10 percent

 

                                                               115

 

      decline.  We did not see that.

 

                DR. GOODMAN:  Dr. Irwin.

 

                DR. IRWIN:  Has the rate of increase

 

      remained the same or has it leveled off, or what is

 

      the direction?

 

                MR. EVANS:  In February, one of our

 

      colleagues, who gave drug use for 2002, that age

 

      group was still 7 to 8 percent of the total.  It is

 

      still the same this year, first six months.

 

                DR. GOODMAN:  So, there has been no great

 

      change.

 

                I will take again other questions out of

 

      order as long as they are directed to a

 

      representative from ODS.

 

                Dr. Marangell.

 

                DR. MARANGELL:  Actually, a comment

 

      directed to this.  I think it is really critical to

 

      this discussion that we keep in mind that our goal

 

      is to protect risk, but also that this is really a

 

      devastating illness, and I am not sure that I

 

      necessarily--I don't want to necessarily see

 

      prescriptions drop.  These people need to be

 

                                                               116

 

      treated.

 

                What we want to do is make sure that

 

      people are educated of what to look for early on in

 

      terms of risk for those people that are at risk,

 

      children or otherwise.  They are not necessarily

 

      the same thing .

 

                DR. GOODMAN:  Other questions for our

 

      speaker?  Dr. Gorman.

 

                DR. GORMAN:  Is the data on the level of

 

      the class or is it on the level of individual

 

      drugs?

 

                MR. EVANS:  We looked at the class as a

 

      whole and then we looked at each individual drug in

 

      the class.  That was according to IMS Health

 

      National Prescription Audit, and we also looked at

 

      the National Disease and Therapeutic Index from IMS

 

      Health, and tried to apply those percentages to

 

      outpatient projected prescriptions.

 

                Only the players changed in that age group

 

      of children 1 through 17.  Paroxetine was knocked

 

      out of the top five, but sertraline still is the

 

      market leader, followed by fluoxetine.

 

                                                               117

 

                DR. GORMAN:  So, the information, there

 

      seems to at this point only be one drug that is

 

      efficacious in this age range, moved it up the

 

      ladder, but didn't make it number one?

 

                MR. EVANS:  Not necessarily.  This is what

 

      we observed when we were just looking at drug use

 

      in prescriptions outpatient, and the National

 

      Disease and Therapeutic Index is an office-based

 

      survey where a drug is mentioned during that survey

 

      and linked to a diagnosis.

 

                DR. GOODMAN:  Can you differentiate

 

      between the prescriber classes, whether it is a

 

      primary care physician versus psychiatrist?

 

                MR. EVANS:  We did look at specialty in

 

      MBA-Plus.  Psychiatry was still about 65 percent of

 

      the specialty, pediatrics, somewhere between 15, 20

 

      percent still.

 

                DR. GOODMAN:  Dr. Fant.

 

                DR. FANT:  Could you comment on the

 

      indications for the prescription, was it all

 

      depression or other off-label--

 

                MR. EVANS:  We looked at mood disorders,

 

                                                               118

 

      anxiety disorders, ADD, and other disorders.  In

 

      age group 12 to 17, it still appears there is not

 

      really any change.  It is still mood disorders,

 

      which includes major depression, is still

 

      two-thirds of the indications.

 

                It looks like in the 1 to 11-year age

 

      group, perhaps more shift to the ADD.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  I heard rather consistently

 

      yesterday a lot of concern about the

 

      direct-to-consumer advertising and the role that

 

      that has played in this, and it may not be the

 

      purview of this committee, but I am asking if we

 

      can address this aspect and how that plays with the

 

      implications of labeling, that if we do put, as was

 

      suggested, a specific negative label in terms of

 

      the indications and certainly as a warning, let

 

      alone a black box warning, that the amplitude of

 

      these warnings are heard.

 

                I mean it is almost a penalty then for the

 

      intense direct-to-consumer advertising, which does

 

      play, as I understand it, a huge role in driving

 

                                                               119

 

      sales for some of these antidepressants.

 

                I just wondered if you could give us some

 

      indication, I mean is there a direct policy with

 

      D.D. Mack how these various gradations get

 

      translated into the few seconds that go on the tail

 

      end of a commercial.

 

                DR. TEMPLE:  They are certainly supposed

 

      to.  The presence of a strong warning or box

 

      warning should be reflected right in the major

 

      statements that are made.  The direct-to-consumer

 

      comes in two flavors, written and TV.

 

                In TV, you can't give as much information

 

      easily, but it has to be available readily.  You

 

      can argue about whether people make use of that

 

      availability.  But the major statement would have

 

      to reflect the balance between those two things.

 

                You know, I am sure people have views

 

      about whether that is done successfully or not.  If

 

      it is written, then, the written statements have to

 

      show that balance.  Any box warning has to be

 

      reflected in it.

 

                So, yes, it is supposed to reflect the

 

                                                               120

 

      balance of information that is in the labeling, so

 

      if the labeling changes, the direct-to-consumer

 

      advertising should change.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  Yes.  Back to the ODS person.

 

      A number of the anecdotes yesterday suggested that

 

      people were put on antidepressants quite off label

 

      and probably not for major depression, but rather

 

      for minor depression and acute depression.

 

                You said that you have the evidence on

 

      mood disorders that includes major depression.  Can

 

      that be disaggregated at all into other non-MDD

 

      forms of mood disorders?

 

                MR. EVANS:  We could look at that.  We

 

      didn't, we lumped them together just for a top-line

 

      statement at this time, because we wanted the focus

 

      to be more on suicidality than drug use.

 

                DR. GOODMAN:  Ms. Griffith.

 

                MS. GRIFFITH:  I wanted to know, since the

 

      data you got was January to June, and the Advisory

 

      didn't come out until late March, is it possible to

 

      look at the data that you got April to June to see

 

                                                               121

 

      if there is a decline?

 

                MR. EVANS:  We did look at it monthly in

 

      those months, and there was not any decline.  I

 

      mean it wasn't a change.

 

                DR. GOODMAN:  Are these new prescriptions?

 

                MR. EVANS:  These were total

 

      prescriptions, new and refill.

 

                DR. GOODMAN:  Did you separate out by new

 

      prescriptions in terms of the monthly rate?

 

                MR. EVANS:  We can, and we did, and we did

 

      not see much of a decline in those, as well.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  On the surface, this looks

 

      not bad in the sense that 65 percent are being

 

      written by psychiatrists, but although I am not

 

      here as a patient representative, I do have a

 

      daughter who has been on these medications, and I

 

      know for a fact that most often psychiatrists do

 

      not prescribe these medications.

 

                My image is that at the end of the day,

 

      they take a whole packet of prescriptions--and I

 

      will be interested to have the psychiatrists

 

                                                               122

 

      respond to this--a whole packet of prescriptions

 

      that have been written by social workers,

 

      pharmacists, psychologists, and sign their name.

 

                So, I think when we are talking about

 

      educating primary care providers, looking at this,

 

      I am reassured, but I know that this does not

 

      represent who is actually writing the

 

      prescriptions.

 

                MR. EVANS:  Yes, this is a limitation of

 

      the data, too, the data is only as good as what the

 

      pharmacist inputs at the computer, and, you know,

 

      if that specialty is on there, hopefully, they will

 

      put that on there.

 

                DR. CHESNEY:  I am sure they don't, but I

 

      think this is very important in the educational

 

      issue, because the people who are prescribing this,

 

      on the whole, are not child psychiatrists, and they

 

      are family practitioners, they are ER physicians,

 

      they are nurse practitioners, they are pharmacists.

 

                I mean I was appalled at what happened

 

      when we visited one of these pharmacists, but no

 

      disrespect to pharmacists, but this is very much

 

                                                               123

 

      happening out there.

 

                DR. GOODMAN:  One last question for ODS

 

      representative from Dr. Wang.

 

                DR. WANG:  I was curious, has anyone

 

      studied what happened after the British

 

      contraindicated these in children, just to get a

 

      sense of what the impact of a labeling change, such

 

      as that, might be?

 

                MR. EVANS:  In February, they looked

 

      through 2002, the market between 2002 and 2003

 

      group, 15 percent with no change really in the

 

      adolescent and children population.  It was still

 

      around 78 percent, so I don't think there was a

 

      change much in this country.

 

                DR. WANG:  But you don't know of any data

 

      in the British--

 

                MR. EVANS:  We didn't look at that.

 

                DR. GOODMAN:  Thank you very much.  You

 

      may step down.

 

                We have six more presenters.  I am not

 

      taking any more, that's it.

 

                Dr. Leslie, do you remember your question?

 

                                                               124

 

                DR. LESLIE:  My question goes way back and

 

      is for the FDA.  I think reading through the

 

      materials that we received from the public, two of

 

      the major concerns about the data that was coming

 

      in were suicidality, et cetera, being captured

 

      under other labels, such as emotional ability, and

 

      then also the issue about dropouts were people

 

      dropping out of either the placebo or the drug

 

      groups, that were having the kinds of adverse

 

      events that were of interest to us, and then not

 

      being counted in the data.

 

                So, I had two questions.  One was do you

 

      feel confident that the data you have received has

 

      addressed those two issues for the analyses that we

 

      looked at yesterday, and the second was what steps

 

      could you potentially take to address those

 

      drawbacks that were raised by the public in the

 

      written requests that proceed from here on out.

 

                DR. LAUGHREN:  I can respond to the first

 

      part of that.  In terms of the data that we

 

      received, if you recall, we issued letters to

 

      companies in July of last year, which specified a

 

                                                               125

 

      very clear research strategy for looking for

 

      adverse events that might be related to

 

      suicidality.

 

                It included both preferred terms and

 

      verbatim terms.  All these data are electronic, so

 

      it was a string search to look for events that

 

      might be possibly related to suicidality.  In

 

      addition to that, we asked companies to look at all

 

      their serious adverse event narratives, any event

 

      that had been classified as a serious adverse

 

      event, they would have to look at and make a

 

      decision whether or not that might represent

 

      suicidality.

 

                Then, later in the year, we issued

 

      additional requests to basically ask them to give

 

      us all the serious adverse event narratives, so

 

      that we could have Columbia themselves look at

 

      those data, and also, all accidental injuries and

 

      accidental overdoses to try and broaden the search,

 

      to make sure that we could capture everything that

 

      might be related.

 

                Now, it is true, despite all of that, it

 

                                                               126

 

      is possible that certain events that didn't rise to

 

      the level of being a series adverse event might

 

      have been captured under some other either verbatim

 

      term or preferred term.

 

                The other question is whether or not the

 

      narratives that we received fully reflected the

 

      case report forms.  The narratives are created by

 

      the companies.  To try and address that, we have

 

      sort of a second level of this contract with

 

      Columbia that is ongoing right now.

 

                We have done a 20 percent sampling of the

 

      case report forms for the narratives we have, to

 

      have them check the narratives against the case

 

      report forms basically to see whether or not they

 

      fully reflected, the narratives fully reflected

 

      what was in the case report form.

 

                In addition to that, we have asked for the

 

      dictionaries.  The dictionaries, basically,

 

      companies, when the code data, they subsume them

 

      under preferred terms, and once they do that, that

 

      creates basically, a dictionary.

 

                So, we have asked for the dictionaries

 

                                                               127

 

      from all these sponsors.  Columbia is currently

 

      looking at those dictionaries to see if there are

 

      any other additional adverse event terms that might

 

      be of interest to look at, again to answer that

 

      question whether or not all relevant events have

 

      been captured.

 

                That is a very tedious, time-consuming

 

      process, but it is ongoing right now.

 

                Dropouts, Dr. Hammad addressed that

 

      yesterday.  We did look at dropouts, and as he

 

      suggested, it is true, many patients were dropping

 

      out for these events.  In a sense, it was almost a

 

      surrogate for that endpoint.

 

                DR. GOODMAN:  Dr. Posner, did you have a

 

      comment?

 

                DR. POSNER:  I just wanted to say that, in

 

      addition, because we asked for all of the

 

      accidental injuries, and that would be the most

 

      likely place, that all of these events involved

 

      some type of injury or another, that you would find

 

      events that were missed, so we can feel reasonably

 

      confident that this body of data represents

 

                                                               128

 

      everything we would want to look for, but we are

 

      doing these additional steps, as well.

 

                DR. GOODMAN:  Dr. O'Fallon.

 

                DR. O'FALLON:  Yes, this sort of follows

 

      up.  We are back to what I am concerned about, the

 

      people who came here, they are worried about the

 

      side effects, the toxicity here.  Right from the

 

      beginning, when you told us back in February about

 

      this study, I was worried about what wasn't

 

      recorded in the drug companies' records, for

 

      whatever reason.

 

                I think that is still, no matter what we

 

      do going forward, we have got to address the issues

 

      there.  So, what I am wondering about, I would like

 

      to propose, and you shoot at and tell me that these

 

      things are not feasible, but it seems to me what we

 

      really need are somehow a standardized suicide

 

      monitoring procedure or whatever for future studies

 

      in mental illness, any kind of a drug that is

 

      targeted toward the mind, we should be looking for

 

      this type of thing, the suicidality side effect.

 

                Then, I think we are going to have to have

 

                                                               129

 

      some sort of standardized suicide coding.  They

 

      have done it in adverse events, not great, but it

 

      could be done better for suicide coding because of

 

      the work that has been done here.

 

                I think this has been a wonderful outcome

 

      in terms of the coding issues.

 

                Now, here is one that is going to kill

 

      everybody, but you can make suicidality a goal, a

 

      primary goal in, say, mental illness or maybe

 

      depression more specifically, where you really

 

      think that this side effect or toxicity, this

 

      adverse event is also a symptom of the disease.

 

                In cancer, they have had to struggle with

 

      the issue of distinguishing side effects from

 

      symptoms of the disease for decades, some way of

 

      going after that.

 

                Just one more comment.  This is a comment.

 

      I believe that there was a 40 percent--in the stuff

 

      I saw before I came out here--I think I saw 40

 

      percent placebo effect in TADS, the TADS study.

 

                If that is true, this is a major issue.

 

      That is one of the reasons why we really do need to

 

                                                               130

 

      have placebo arm in these different studies,

 

      because if 40 percent of this population will have

 

      a beneficial effect due to sugar pills, to try to

 

      tease out true effectiveness of these medications

 

      given their severe side effects, it is very

 

      important that we have a placebo arm even going

 

      forward.

 

                I know that you are not thinking of it,

 

      but I think some of the people in the room are

 

      wondering why we have to go with sugar pills.

 

                DR. LAUGHREN:  Let me comment on the last

 

      point first.  We clearly agree with you about

 

      placebo, but it is not just the act of giving a

 

      pill.  In all of these trials, there is a lot that

 

      happens that results in improvement.

 

                DR. O'FALLON:  Yes, I know that.

 

                DR. LAUGHREN:  There is a lot of

 

      attention, the patients have a lot of interaction

 

      with staff.  That is really the placebo effect.

 

                But the other point you are making, I

 

      completely agree that ascertainment is ultimately

 

      the issue.  If you don't collect the information,

 

                                                               131

 

      it doesn't make any difference how carefully you

 

      search the database, if it wasn't collected, it's

 

      not there, so ascertainment is key.

 

                Again, that is one of the things that we

 

      hope to get out of this effort with Columbia is a

 

      better guidance document for future trials to make

 

      sure that suicidality is properly ascertained, but

 

      it is an evolving thing in the field.  I mean there

 

      is not at this point in time an optimal way of

 

      doing that, so we hope to get an instrument that we

 

      can apply for future trials.

 

                Again, I agree with you that coding of

 

      data needs to be standardized, and again that is

 

      one of the things that we expect to come out of

 

      this.

 

                DR. POSNER:  Could I just add to that?  We

 

      are very committed to addressing the question that

 

      you are referring to.

 

                DR. GOODMAN:  Would you bring the

 

      microphone closer.

 

                DR. POSNER:  I said we are very committed

 

      to addressing this issue in terms of suicidality

 

                                                               132

 

      adverse event monitoring, and Dr. Laughren

 

      mentioned guidelines that we are going to write and

 

      measures that we actually have developed that we

 

      can implement in all trials, that will help us

 

      collect the right data and then be able to use

 

      these consistent definitions to classify events, so

 

      we can make sense across all of these trials.

 

                What is important to note is that we are

 

      working on a National Institute of Mental Health

 

      study called TASA, Treatment of Adolescent Suicide

 

      Attempters, which is very focus on this issue of

 

      adverse event monitoring, and it is wonderful

 

      because it is helping us inform the process, so we

 

      have developed very, very rigorous standards of how

 

      we ask these questions, what measures we use, and

 

      how to do it consistently, and that will help

 

      inform the guidelines and the measures that

 

      industry and everybody else can use.

 

                So, we have made a lot of progress in

 

      that, I think.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I just want to follow up on

 

                                                               133

 

      the last discussion.  It seems to me there are two,

 

      somewhat separate things, and I would be interested

 

      in people's views.

 

                One is to make the periodic routine

 

      question better than it is.  There is a suicide

 

      item on the score, but that didn't show anything.

 

      Maybe that will never show anything because when it

 

      happens, it happens abruptly and you don't happen

 

      to pick it up at the two-week period, but it does

 

      seem as if a better questionnaire on that question,

 

      done routinely, might be useful.

 

                The second part of it is how to

 

      characterize events, what questions to ask about

 

      those, what to write down.  Is that what you are

 

      thinking, they are two somewhat different things?

 

                DR. LAUGHREN:  I agree, they are two

 

      separate things.  There is the suicide item that is

 

      part of every one of these instruments and sort of

 

      standardizing how that routine information is

 

      elicited, but then when an event occurs, you have

 

      to ensure that the appropriate questions are asked

 

      to flesh out that situation, so that someone down

 

                                                               134

 

      the road who is looking at the data is able to make

 

      sense of it.

 

                DR. O'FALLON:  But I would like to point

 

      out that the monitoring procedures, especially for,

 

      say, the first two weeks or something like  this,

 

      should include a real collaboration with the

 

      children and their caregivers, their parents,

 

      whoever they are living with, to be on the watch

 

      for those and to report them immediately, and that

 

      those things would be part of the data.

 

                DR. LAUGHREN:  Let me just respond to that

 

      quickly.  Basically, you are switching gears to a

 

      clinical setting, I think, other than a clinical

 

      trial.

 

                DR. O'FALLON:  You guys can write the

 

      regulations for the clinical trial, right?

 

                DR. LAUGHREN:  Right, but obviously, the

 

      points that you are making apply to clinical

 

      practice, as well.

 

                DR. O'FALLON:  Yes, but they would apply I

 

      would say in the clinical trial, because I think

 

      that you are not possibly getting all your

 

                                                               135

 

      information.  If you don't come in for two more

 

      weeks, people forget that they were scared 10 days

 

      ago.

 

                DR. LAUGHREN:  Absolutely, I agree.

 

                DR. POSNER:  I just wanted to add that we

 

      are also working with the CDC just on this

 

      question, what are the right one or two questions

 

      that need to be asked in any trial or clinical

 

      setting to get this information to be able to

 

      classify it appropriately, which is exactly what we

 

      are talking about, and it is not necessarily the

 

      best questions on the measures that were used in

 

      this trials, but that is exactly the pertinent

 

      point in clinical setting or in research settings

 

      with the increased monitoring that you are

 

      referring to.

 

                DR. GOODMAN:  I am going to need to wrap

 

      up the remaining questions in the next five

 

      minutes.

 

                Dr. Irwin.

 

                DR. IRWIN:  The question I wanted to ask

 

      specifically was related to the one that is on the

 

                                                               136

 

      table right now.  Yesterday, we heard from several

 

      families and individuals about really homicidal

 

      behavior and more violent behavior outwardly

 

      directed, not internally directed.

 

                Of concern to me is that the focus has

 

      been so much on suicide, but what I wanted to know

 

      is what kind of monitoring or what kind of tools

 

      are in place to really measure that phenomenon in

 

      these trials, because it seems to me that we don't

 

      have any data that has been shown to us at least on

 

      adverse experience or events with the clinical

 

      trials.

 

                DR. LAUGHREN:  Our focus here clearly has

 

      been on suicidality, and not on hostility and

 

      violence.  There was a lot less of that in these

 

      trials than we had suicidality, and we have not

 

      come to grips with that yet, but it is a whole

 

      other area that needs to be fleshed out and

 

      developed in the same way that suicidality has been

 

      fleshed out because again we have included in our

 

      database information on whether or not these

 

      individual patients at some time during the course

 

                                                               137

 

      of treatment were coded as having hostility or

 

      agitation as a preferred term.

 

                If you go back and look at what got

 

      subsumed under that, I am sure it is going to be

 

      quite different depending on different sponsors,

 

      and it really requires a parallel development to

 

      try and understand what that means.

 

                Again, all the things we have been talking

 

      about for suicidality apply to that domain, you

 

      know, how do you ascertain for it, what kind of

 

      questions do you ask to flesh it out, it is a real

 

      problem.

 

                DR. GOODMAN:  By the way, the placebo

 

      response rate from the TADS trial is 35 percent.

 

      Looking at the paper again, I see 35 percent.

 

                DR. O'FALLON:  Okay.

 

                DR. NEWMAN:  Just to clarify, that is much

 

      or very much improved in the TADS trial.

 

                DR. GOODMAN:  I don't think that one is

 

      based on the CDRS, right, that is what you are

 

      saying, it is based on the CGI?

 

                DR. NEWMAN:  The dichotomous outcome was

 

                                                               138

 

      were they much or very much improved, so if you

 

      said just improved, reasonably, it would have been

 

      a lot more.

 

                DR. GOODMAN:  But that is the standard, I

 

      mean it has to be much or very much improved to be

 

      a responder.  That is pretty much across all

 

      clinical trials.

 

                Dr. Pine, please.

 

                DR. PINE:  I want to return to a point

 

      that was raised by Dr. Goodman and just call the

 

      committee's attention to a couple things that he

 

      said and then also raised a couple other issue

 

      relevant to the discussion about 10 or 15 minutes

 

      ago with FDA.

 

                That is the issue of both how perplexing,

 

      but also how important it is to think very

 

      carefully about the efficacy data and the

 

      difference between the data for fluoxetine, on the

 

      one hand, and all the other antidepressants, on the

 

      other hand, and how do we understand that.

 

                Number one, just to underline that I agree

 

      that the importance of that point cannot be

 

                                                               139

 

      overstated.  I guess there is a couple of issues

 

      that were not discussed 10 or so minutes ago in

 

      sufficient detail, and really two points to raise.

 

                One is that I do appreciate from a

 

      regulatory standpoint that it is very difficult to

 

      specify exactly how one is to do an appropriate

 

      study.  We talked about a lot of the details that

 

      we don't need to go over again except one thing was

 

      not discussed, and that was a discussion of the

 

      level of rigor that goes into both the training of

 

      the investigators who are going to ascertain the

 

      samples and document the diagnosis, on the one

 

      hand, but then also follow the response of the

 

      patients throughout the trial.

 

                Then, I think the last thing to say about

 

      that specific point is that when we look at the

 

      data that have been published, and probably the

 

      most extensive data are from the sertraline trial

 

      as opposed to the TADS trial, with the sertraline

 

      trial being a pharmaceutical-sponsored study that

 

      appeared in JAMA, and the TADS trial being an

 

      NIH-sponsored trial that was also published in JAMA.

 

                                                               140

 

                There are some fairly clear signs that the

 

      manner in which investigators were trained, that

 

      the criteria for enrolling patients for the process

 

      of evaluating the response as it was manifest

 

      throughout the trial was quite different in those

 

      two studies.

 

                Again, when we come to the issue of how

 

      important it is to compare the data for fluoxetine

 

      and the data for the other agents, I think we need

 

      to acknowledge that there are already signs in the

 

      data that have been published in the reports that

 

      have appeared in peer review, that the quality of

 

      the studies appears to be different.

 

                I think it is also important to note that

 

      if we were to look at the efficacy data by industry

 

      sponsor versus federally funded, there have been,

 

      to the best that I can recall right off the top of

 

      my head, two federally funded SSRI trials, both are

 

      positive.

 

                So, we are 2 out of 2 on that score,

 

      whereas, if we look at all the others, we are

 

      basically 1 out of 13 or 1 out of 14.

 

                                                               141

 

                DR. GOODMAN:  Those two are both in

 

      fluoxetine, isn't that correct?

 

                DR. PINE:  That's true, so, you know, we

 

      have a confound between federally sponsored and the

 

      compound, but those are the data that we do have,

 

      and I think given the issues that I just discussed,

 

      you know, we are going to be very hard pressed to

 

      say this is a funding or design feature issue,

 

      which it might be, or that this is a medication

 

      issue, which again it might be.

 

                DR. GOODMAN:  I want to make sure I am

 

      clear on the source of the fluoxetine data for the

 

      clinical trials.  I think it was mentioned before

 

      that some of the data that contributed, I don't

 

      know which of the positive studies, but one of the

 

      positive studies at least, was actually a study

 

      that had been conducted by Dr. Emslie, and that, in

 

      fact, was a federally funded study, is that

 

      correct?

 

                DR. LAUGHREN:  Yes, the Emslie study was

 

      funded by NIMH, but there was another independent

 

      trial that was funded by Lilly, that was also

 

                                                               142

 

      positive.  The TADS trial was not part of our

 

      decisionmaking, that came later.  So, there was

 

      another positive fluoxetine study that was done

 

      entirely under Lilly's sponsorship.

 

                DR. GOODMAN:  Dr. Rudorfer, did you have a

 

      comment?

 

                DR. RUDORFER:  Just on this last point, I

 

      think that was back in '80s, am I correct, that the

 

      Emslie study was first done?

 

                DR. GOODMAN:  No, '97.

 

                DR. RUDORFER:  Because we have in our

 

      material, a fluoxetine clinical trial that goes

 

      back to the '80s.

 

                DR. PINE:  That was a very small study, at

 

      least as I understand it from reviewing the

 

      material.  Maybe you want to comment on the 1980

 

      study.

 

                DR. LAUGHREN:  I am not familiar with that

 

      one.  I think the Emslie study was maybe early

 

      '90s, but we can probably check.  I am sure it is

 

      in Dr. Dubitsky's review.

 

                DR. PINE:  Well, in the material that we

 

                                                               143

 

      received, there was a study that was described,

 

      that I recognized just from the description as a

 

      study that was published in 1990 by Simian as the

 

      first author.

 

                DR. LAUGHREN:  That was probably, I think

 

      it was HCCJ.  That was the study that was

 

      terminated early.  I think there were only 40

 

      patients in that trial.  That was not one of the

 

      trials that was the basis of our approval of the

 

      claim in fluoxetine.

 

                DR. RUDORFER:  Could I insert just another

 

      quick safety-related question?  We were talking

 

      before about if there is a way to judge the impact

 

      of the label change that was made in March, since

 

      that would seem important to us in terms of whether

 

      an additional change would be helpful.

 

                I am wondering if the Med Watch Program

 

      offers any clues there in terms of reports from the

 

      clinical community of adverse events, whether there

 

      has been a change in 2004 versus last year, for

 

      instance.

 

                DR. TRONTELL:  We haven't looked at that. 

 

                                                               144

 

      The Med Watch Program, just to be very precise, has

 

      two components. Med Watch itself involves reports

 

      that come directly to the FDA, and don't come

 

      through the pharmaceutical manufacturers.  That is

 

      actually a minority of the reports, 5 or 6 percent.

 

                The Adverse Event Reporting System, which

 

      Med Watch and the manufacturers feed into, is much

 

      larger.  The challenge was reports that came to the

 

      agency spontaneously, that you actually can, in

 

      fact, see a paradoxical increase in reports when

 

      these events become known to the public, so it is

 

      not a reliable way to tell you whether or not

 

      things are changing, because we know not every

 

      report comes to us and the factors that influence

 

      reporting are changing dependent on scientific and

 

      media attention.

 

                DR. RUDORFER:  So, within the agency, do

 

      you see any index that you can use to judge the

 

      impact of the label change in March?

 

                DR. TEMPLE:  The only thing that you could

 

      measure properly is use, so if the warning sort of

 

      made people think twice, and decided to watch and

 

                                                               145

 

      wait instead of treat, you could detect that

 

      through the data that have been described.

 

                But the adverse events are unpredictable.

 

      We know that not all serious events are reported,

 

      you know, various estimates go from 1 percent to 10

 

      percent to higher, but as Anne said, if you change

 

      public attention to something, you can get

 

      increased reports without having increased numbers.

 

                It is very hard to know that, to know

 

      about those things.  What you can think about is

 

      looking at databases that have reports of these

 

      things, the kind of thing that Jick did and others,

 

      but the events in question, first of all, you are

 

      not sure how well they are described, you are not

 

      sure whether they get into the reporting system.

 

      It is very difficult territory.  You know,

 

      epidemiology is difficult enough, this is

 

      particularly difficult, because you don't know how

 

      they are classified and it is really hard.

 

                DR. TRONTELL:  Just to follow up, if you

 

      want to see a change, you may actually have to wait

 

      some time before you see a change in the outcome. 

 

                                                               146

 

      If you wanted simply to see if prescribing

 

      practices are different, I think you might have to

 

      go even beyond the use data we have, even beyond,

 

      say, new prescription to see if starts on these

 

      products are changed, to actually do some active

 

      surveillance and survey clinicians or survey

 

      patients to find out if, in fact, there is a

 

      different process for introducing these products.

 

                DR. GOODMAN:  Dr. Marangell, did you have

 

      a question?  Okay.

 

                Dr. Fant.

 

                DR. FANT:  I just want to follow up on

 

      that and the comments and questions that were

 

      raised by Dr. Chesney earlier.

 

                One of the things that I was struck by

 

      yesterday and hearing the testimony of the

 

      families, and from my own personal experiences with

 

      friends and family members, much of the discussion

 

      here has been focused on the use and efficacy and

 

      outcomes of these drugs related to major depression

 

      in the trials that have looked at that, but the

 

      off-label use of these medications is fairly

 

                                                               147

 

      promiscuous, and the prescribers extend well beyond

 

      those that are trained in the care of the mentally

 

      ill.

 

                I think that is a real problem when you

 

      have ob-gyns prescribing it and giving it away for

 

      ladies who just may be a little moody, you know,

 

      when they come in, or feeling a little down, and

 

      without having any consultation or evaluation by

 

      someone who is specifically trained to evaluate

 

      that, I think that is a problem and I don't think

 

      that represents an isolated incident.

 

                I think any labeling change considerations

 

      really need to not necessarily be directed to

 

      regulate how medicine is practiced, but to somehow

 

      influence or disincentivize that kind of

 

      unrestricted free-lance approach to how these

 

      medicines are used.

 

                I think that has to be kept in mind, and I

 

      would just like to emphasize that.

 

                DR. GOODMAN:  Dr. Perrin?  Dr. Irwin.

 

                DR. IRWIN:  I would just like to respond

 

      to that. I mean I agree with you that the

 

                                                               148

 

      distribution of these medications by individuals

 

      who aren't trained is really a worrisome fact, but

 

      I will tell you in San Francisco County, to find an

 

      individual who is trained to see a child with a

 

      mental health disorder is virtually impossible

 

      unless someone walks through the door with $175 in

 

      hand to give to a psychiatrist.

 

                So, I think that what has happened, and

 

      it's a fundamental problem that we are dealing

 

      with, and it is not the purview of this committee,

 

      that the issue of mental health problems in

 

      children and identifying individuals to care for

 

      them or finding individuals to care for them is

 

      really very, very difficult, and it pushes primary

 

      care clinicians to prescribe and make judgments,

 

      and provide medications when they probably should

 

      not be without appropriate consultation.

 

                So, I think it is a real major crisis.

 

                DR. FANT:  I agree 100 percent, and I make

 

      those comments fully cognizant of the fact that the

 

      mental health arm of health care in this country is

 

      probably in worse shape than health care in the

 

                                                               149

 

      broader context.

 

                Certainly, in terms of its availability,

 

      certainly in terms of its coverage by health

 

      insurance plans, it is not sufficient to do what it

 

      needs to do.  But I think it is important not to

 

      make it easier for bad medicine to be practiced

 

      under those conditions, but to somehow create

 

      conditions that kind of force, at least under those

 

      suboptimal conditions, some better protections and

 

      better practices.

 

                DR. GOODMAN:  Drs. Pfeffer and Wang, and

 

      then we are going to take a break.

 

                DR. PFEFFER:  I would like to just go to

 

      another area of our discussion and that is to focus

 

      on what I will call the real world issues.  I think

 

      that the speakers yesterday in their own way gave

 

      us a representative view to some degree of that,

 

      and I am wondering, someone mentioned, I think Dr.

 

      Pine, about prescriptions and can they be a little

 

      bit more either regulated or I will say focused.

 

                I am wondering if we might consider the

 

      option of when a physician writes a prescription

 

                                                               150

 

      for a medicine, such as an SSRI, that what is also

 

      included on the prescription is the diagnosis, so

 

      that we would have the kind of data that we just

 

      heard, but amplified by some knowledge at least of

 

      what the clinician is thinking about the rationale

 

      for the prescription.

 

                I know we do that in New York relative to

 

      controlled substances at times, or other, in the

 

      clinics, for example, the prescription forms

 

      actually have that on their forms.  So, I don't

 

      think it's any greater violation of patient's

 

      privacy than to say a patient is already on a

 

      medication.

 

                It might provide us with some additional

 

      national-like real world practice ideas.

 

                The other comment I would like to make is

 

      that I think it was Dr. Zito who mentioned

 

      yesterday about a proposal of having sort of a more

 

      widespread, sort of service oriented approach to

 

      study the issues also.

 

                So, I think while we are talking about

 

      constructing drug trials that are carefully

 

                                                               151

 

      controlled and carefully defined in terms of the

 

      population, given the fact that the prescriptions

 

      are being used much more widely, it might be

 

      helpful for us to have a view, a focus, and how can

 

      we study these issues also, and the studies need to

 

      be done obviously in different ways.

 

                DR. GOODMAN:  Dr. Wang, did you have a

 

      question?

 

                DR. WANG:  No, it was covered.

 

                DR. GOODMAN:  I would like to take a

 

      10-minute break and then we are going to return for

 

      a presentation, and we need to at least handle one

 

      of the questions before we break for lunch.

 

                [Break.]

 

                DR. GOODMAN:  We are about to begin.

 

      Please take your seats.

 

                If you recall from yesterday, when Dr.

 

      Wysowski was presenting, she said she had some

 

      additional data that was provided on the Jick

 

      study, and we asked her to defer until today to

 

      present it.  I think she should be able to do that

 

      pretty quickly, also give you an opportunity to ask

 

                                                               152

 

      her any other questions that you think are relevant

 

      to today's discussion.

 

                At the close of that presentation, we are

 

      going to get down to business in addressing these

 

      questions sequentially.  In the course of doing so,

 

      I am going to ask you to, as best as possible, to

 

      restrict your comments and the discussion to the

 

      question at hand.  Otherwise, I may defer that to

 

      later in the course of our discussions.

 

                So, with that, Dr. Wysowski, could you go

 

      ahead and present the data.  Maybe you want to give

 

      us a little bit of a sense of the context first.

 

                         Diane Wysowski, Ph.D.

 

                DR. WYSOWSKI:  Right.  I don't know how

 

      important or relevant this is at this point in

 

      time, but I am going to ask you to switch gears

 

      from the clinical trial data and think back to my

 

      presentation yesterday morning, which was on

 

      patient level controlled observational studies.

 

                I talked about two studies, the Jick study

 

      that was published in JAMA, and the Valuck study,

 

      but I am going to have you focus on the Jick study

 

                                                               153

 

      and recall that it was a case-controlled study.  It

 

      was done in the United Kingdom and the General

 

      Practice Research Database, and it examined the use

 

      of four antidepressants - amitriptyline,

 

      fluoxetine, paroxetine, and dothiepin in suicidal

 

      cases versus non-suicidal controls.

 

                In their original analysis, Dr. Jick and

 

      his colleagues used dothiepin as the reference

 

      category.

 

                At FDA's request, Dr. Jick and colleagues

 

      kindly re-analyzed their multivariate data for

 

      nonfatal suicidal behavior using amitriptyline

 

      rather than dothiepin as a reference category.

 

                The data are controlled for age, sex,

 

      calendar time, and time from first antidepressant

 

      prescription to onset of suicidal behavior.  Now,

 

      in the lefthand portion of the slide, you see their

 

      original analysis with the risk ratios and 95

 

      percent confidence intervals with dothiepin as a

 

      reference category.

 

                On the right, with amitriptyline as a

 

      reference category, the risk ratios for both SSRIs

 

                                                               154

 

      increased and became statistically significant at

 

      the 0.05 level.  The risk ratio for dothiepin was

 

      1.21 with a 95 percent confidence interval that

 

      included 1.

 

                For fluoxetine, it was 1.40 with a 95

 

      percent confidence interval of 1.03 to 1.91, and

 

      for paroxetine, it was 1.55 with a 95 percent

 

      confidence interval of 1.11 to 2.16.

 

                Now, the investigators asked that their

 

      interpretation of these results be presented

 

      verbatim to the committee.  We advised that these

 

      post-hoc analyses be interpreted with caution.

 

      They were not the preplanned primary analysis, and

 

      the p-value and confidence intervals are not

 

      adjusted for multiple hypothesis testing.

 

                We think conservative interpretation

 

      requires that p-values lower than 0.05 or

 

      confidence intervals with coverage greater than 95

 

      percent would be necessary to assert that these

 

      results are statistically significant with overall

 

      5 percent Type 1 error.

 

                These results are consistent with the

 

                                                               155

 

      interpretation in our report that the risk of

 

      suicidal behavior after starting antidepressant

 

      treatment is similar among users of amitriptyline,

 

      fluoxetine, and paroxetine compared with the risk

 

      among users of dothiepin, and that a possible small

 

      increase in risk bordering statistical significance

 

      among those starting the newest antidepressant

 

      paroxetine is of a magnitude that could readily be

 

      due to uncontrolled confounding by severity of

 

      depression.

 

                Moreover, we did not observe an increased

 

      risk of suicide itself for the users of

 

      amitriptyline, fluoxetine, or paroxetine compared

 

      to users of dothiepin.

 

                So, that is their supplementary analysis,

 

      it was a post-hoc analysis, and that is their

 

      interpretation of the results.  It did increase the

 

      two SSRIs to the level of statistical significance

 

      at the 0.05 level.

 

                DR. GOODMAN:  Now, dothiepin is not a

 

      medication available in this country.  It is also a

 

      tricyclic antidepressant, as is amitriptyline,

 

                                                               156

 

      isn't that true?

 

                DR. WYSOWSKI:  That is correct, but again,

 

      the choice of the reference category makes a

 

      difference in the results.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  I think it is very helpful to

 

      have these additional analyses.  I really had,

 

      though, a couple methodologic questions about this

 

      and the Valuck study that I think are fairly quick.

 

                One is, in the British database, how valid

 

      or reliable are these measures of suicidal

 

      behaviors, not achieved suicide, and similarly, how

 

      good were the measures in the Valuck study of--I

 

      can't remember the terminology they used off the

 

      top of my head--but of suicidal behaviors given the

 

      kind of database they had to work from?

 

                DR. WYSOWSKI:  Well, one of the concerns

 

      that I had, which I expressed yesterday, was that

 

      the possibility of missing data and incomplete

 

      ascertainment, and misclassification, and when you

 

      are talking about suicide ideation, which is a

 

      softer, more subjective diagnosis, it is difficult

 

                                                               157

 

      to know how many people actually come forward and

 

      report that.  I guess if it's a serious concern,

 

      they come forward and report it.

 

                One of the things that I think Dr. Jick

 

      says is that there is some possibility--the general

 

      practitioners on which the data are based, they

 

      make these notes, and it looks like they get

 

      entered into the computer about 90 percent of the

 

      time is what I figure from what Dr. Jick says here.

 

                So, if there is some misclassification in

 

      that way for the 10 percent that don't get entered,

 

      of the missing data, you would be concerned.

 

                DR. PERRIN:  But it requires that the

 

      general practitioner actually puts it in his or her

 

      notes for it to get even possibly entered.  There

 

      must be substantial variability in that phenomenon.

 

                DR. WYSOWSKI:  Well, they do have

 

      computers, and these people were trained, and so

 

      they achieved a level of training success to be

 

      entered and qualified for this database, but it

 

      sounds to me like--it says here, "Information on

 

      patient referrals and hospitalizations available in

 

                                                               158

 

      the manual medical records in the general

 

      practitioners' offices was recorded on the computer

 

      more than 90 percent of the time."

 

                So, that implies that about 10 percent of

 

      the time you are not going to find the data there.

 

      It was in the manual record, but not on the

 

      computer.  So, there is some possibility for some

 

      error there.

 

                Now, how that actually works out into the

 

      results, don't know really.

 

                DR. PERRIN:  For the Valuck study, do you

 

      have information on their measure of suicide

 

      attempt?

 

                DR. WYSOWSKI:  The Valuck study was based

 

      on paid medical claims data and of 70 managed

 

      health care organizations.  I talked to Dr. Valuck

 

      about that, and he said that he thought that the

 

      PharMetrics integrated outcomes research database

 

      that he used, which is the 70 managed health plans,

 

      that the data was very good and very complete, but

 

      one of the things that is a problem with his study

 

      is that he cannot go back and validate through

 

                                                               159

 

      medical records the information that he has on the

 

      computer, so that is one problem, but he said that

 

      was better than most Medicaid databases.

 

                DR. PERRIN:  Most Medicaid databases are

 

      very poor for analyzing children's mental health

 

      services.

 

                DR. WYSOWSKI:  Right.

 

                DR. GOODMAN:  Dr. Ortiz, did you have a

 

      question?

 

                DR. ORTIZ:  I just was wondering if Dr.

 

      Wysowski could clarify the risk ratio for this.  Is

 

      it suicidal behavior, suicide attempts?

 

                DR. WYSOWSKI:  It is nonfatal suicidal

 

      behavior, which includes ideation and attempts.

 

                DR. GOODMAN:  I believe in reading the

 

      Jick paper, there was reference made to 15

 

      completed suicides in the entire population.

 

                DR. WYSOWSKI:  Right.

 

                DR. GOODMAN:  And they go on to point out,

 

      those 15 were within the 10 to 19 age group, in

 

      fact.  There were others obviously outside that

 

      range, but that none of the 15 in that younger age

 

                                                               160

 

      group were on antidepressants.

 

                DR. WYSOWSKI:  Right.  Actually, they

 

      include suicides in their study, and there were 17

 

      cases and 157 controls, but also I think Dr.

 

      Goodman is referring to the fact that, yeah, there

 

      is some information on children that committed

 

      suicide, and it was somewhere on the order of about

 

      15.

 

                But that makes me wonder.  I wasn't able

 

      to determine whether that 15 is a reasonable rate

 

      or not, so, you know, whether that is

 

      under-ascertainment or not, we don't really know.

 

                DR. GOODMAN:  That, in part, was my

 

      question.  I wasn't sure from reading the paper how

 

      they ascertained it, but it still was striking that

 

      none of them were on antidepressants.

 

                DR. WYSOWSKI:  However, they do say here

 

      that causes of death in particular are routinely

 

      recorded, so you would think that they would have

 

      pretty good data on deaths, but you don't know, and

 

      all the suicides, but you don't know.

 

                DR. GOODMAN:  Dr. Gibbons.

 

                                                               161

 

                DR. GIBBONS:  Most statisticians view

 

      large-scale naturalistic observational studies as

 

      statistical atrocities.  I am not one of them.  I

 

      think there is a great deal to be learned from

 

      naturalistic observational data.

 

                Having said that, I think it is very, very

 

      important to protect oneself from bias due to

 

      selection, and it appeared to me here that, you

 

      know, there is all kinds of selection bias as to

 

      who gets on to what kind of medication.

 

                I guess, first, there is a question, well,

 

      first, there is a statement.  These are sorts of

 

      cases where things like propensity score matching

 

      and other sorts of methods that have been around

 

      for a long time for the analysis of observational

 

      data are critically important.

 

                Covariate adjustment typically, which I

 

      imagine was done here, can be very misleading,

 

      because it assumes linearity, and many of these

 

      relations aren't linear, and, in fact, the biases

 

      cannot be overlapping.  You could have situations

 

      where the people who got on to one drug, don't look

 

                                                               162

 

      anything like the people in the other, and, in

 

      fact, the use of covariates in a general linear

 

      model will be more misleading than helpful.

 

                Have they made any attempt to do this

 

      simple analysis using some form of propensity score

 

      matching to ensure that the likelihood of taking

 

      the drugs is consistent between the two groups?

 

                DR. WYSOWSKI:  Yes.  Dr. Jick did not, but

 

      Dr. Valuck did, and I presented those results

 

      yesterday.  In the poster, there was no increase in

 

      risk for any of the antidepressants, but they had

 

      classes of antidepressants, as you recall.  They

 

      are not individual antidepressants.

 

                For the expanded study, which was based on

 

      24,000 patients with diagnosis of major depressive

 

      disorder, they did find a relative risk of about

 

      1.58 for the SSRIs, but it was not statistically

 

      significant.  They did include a propensity

 

      matching adjustment.

 

                DR. GIBBONS:  Given that we are seeing

 

      this consistent 1.4, 1.4 through a lot of the

 

      analyses, it would be very interesting either to

 

                                                               163

 

      have them do those analyses or perhaps the

 

      committee would think about performing such

 

      analyses if we could acquire the data.

 

                DR. GOODMAN:  Thank you very much.

 

                DR. WYSOWSKI:  You are welcome.

 

                    Discussion of Questions and Vote

 

                DR. GOODMAN:  It is time to roll up our

 

      sleeves.  I would like you to pull out the

 

      questions before us.  It was given out attached to

 

      the agenda for the meeting, on one page, or you can

 

      use it as represented in the slide handout that Dr.

 

      Laughren gave earlier today.

 

                Let me make a few comments first, before

 

      we begin to address these questions.  For the most

 

      part, they are focusing on risk, specifically, risk

 

      of suicidality, and it seems to me it is not until

 

      Question 4 that we need to be thinking about ratio

 

      of benefit to risk.

 

                So, I think for the most part, the first

 

      three questions focus entirely on risk, but in

 

      order to come up with some recommendations in terms

 

      of regulatory actions, we do need to consider the

 

                                                               164

 

      balance between risk and benefit.

 

                Also, in talking about suicidality, there

 

      are some definitional questions that have come up

 

      all along, and I think we need to be, among

 

      ourselves, as clear as possible what we mean when

 

      we say suicidality.  Maybe there will be some

 

      benefit from the work that the Columbia group has

 

      done to help us make sure that we are using the

 

      same language.

 

                Also, I think it behooves us to try to

 

      translate what suicidality means to the general

 

      public.  In looking at some samples of the morning

 

      papers, front page New York Times, front page USA

 

      Today, there are headlines about how it has been

 

      concluded already, based on yesterday's discussion,

 

      that the antidepressants increase suicidality in

 

      children.

 

                I am trying to imagine.  I would be

 

      interested in how a parent, in reading that, what

 

      they would think, what do they mean by suicidality.

 

      My guess is that they are going to think that it is

 

      suicide.  As we discussed yesterday, this includes

 

                                                               165

 

      suicide, it includes suicide attempts, but our

 

      definitions also includes preparatory actions and

 

      ideation.

 

                So, I think we need to be very clear that

 

      we are using the same terminology, and maybe Dr.

 

      Posner will be able to help us along the way in

 

      that.

 

                As I said a little bit earlier, that we

 

      are going to try to keep very focused on the

 

      question at hand, so I may defer some of your

 

      questions until later in the day.  I would like

 

      very much to be able to answer at least one,

 

      perhaps two, questions before breaking for lunch,

 

      so that the reward will be lunch to get some of

 

      this work done.

 

                My sense is that Question 1 may be the

 

      easiest question, and then they may get

 

      increasingly more difficult, so I think we need to

 

      pace ourselves accordingly.

 

                Also, just as another kind of overarching

 

      statement is that for the most part, at least in

 

      the beginning, we are asked to focus exclusively on

 

                                                               166

 

      the clinical trials, but as we begin to deliberate

 

      on issues of risk and benefit, then, we have to

 

      then begin to consider data from outside those

 

      clinical trials and therefore, our task becomes

 

      more difficult and more complex.

 

                Any questions about process before we

 

      begin our comments?

 

                MS. DOKKEN:  Just before we start on the

 

      specifics of Question 1 or 2, as someone new to the

 

      committee, who is trying to listen and learn about,

 

      I do have a question related to guidance from both

 

      the Chair and the staff, and I would feel more

 

      comfortable hearing about this, I guess, before we

 

      even get into Question 1, which is I hear still

 

      some discomfort about the data.

 

                On the one hand, the options of labeling

 

      and black boxes, et cetera, but I hear another

 

      theme, too, which was articulated in particular by

 

      Ms. Griffith, and that is, even though we are two

 

      advisory committees only, and even though the FDA

 

      is regulatory, is it within our purview, and more

 

      so, do we have a responsibility to go beyond

 

                                                               167

 

      something narrow like that, like labeling, and also

 

      talk about the issues.

 

                As I said, Ms. Griffith referred to

 

      education, not just of clinicians but of the

 

      public, and how much time, you know, can we

 

      allocate time to that, as well.

 

                DR. GOODMAN:  Dr. Katz.

 

                DR. KATZ:  One response to the last part.

 

      I think when we get to the appropriate time in the

 

      meeting, I think  you should discuss in a very

 

      freely ranging way what provisions you think would

 

      be a good idea to institute in order to use these

 

      drugs safely.

 

                I wouldn't worry so much about the nuances

 

      of what your responsibility is or what we can do

 

      from a regulatory point of view.  If there is

 

      something that you recommend, and we have already

 

      talked a little bit about this, if there are things

 

      that are outside our purview and we are incapable

 

      legally of instituting, we will get back to you on

 

      that or will let you know, but I think we really

 

      want to hear a relatively wide-ranging conversation

 

                                                               168

 

      about what sorts of things you think might be

 

      useful.  If we can't do it, we will let you know,

 

      but we would like to hear about it.

 

                DR. GOODMAN:  Any other comments about

 

      process?

 

                I also noticed behind me that we have

 

      Question No. 1 projected, so you don't need your

 

      reading glasses to address it.

 

                Let me read it.  Please comment on our

 

      approach to classification of the possible cases of

 

      suicidality.  Here, by parentheses, that word has

 

      been defined.  Suicidal thinking and/or behaviors,

 

      and/or analysis of the resulting data from the 23

 

      plus 1 pediatric trials involving 9 antidepressant

 

      drugs.

 

                Another thing I probably should mention is

 

      that in terms of the questions we vote on, clearly,

 

      No. 2 is one we are going to vote on, and a yes

 

      vote then would lead us into No. 3.  I am not sure

 

      that No. 1 requires a vote.  You are asking for

 

      comment.

 

                Are you asking for a vote on this

 

                                                               169

 

      question?

 

                DR. KATZ:  No, we are not asking for a

 

      vote, just  comments, just a general sense of the

 

      committee.

 

                DR. GOODMAN:  I was going to actually

 

      start and try to answer the question first, to go

 

      out on a limb, since this is the easiest question,

 

      I thought I would take a stab at it, in my opinion.

 

      But if there are other comments, and I will be

 

      going around the table, so that each of you will

 

      have a chance to comment, so unless it's really a

 

      process question, you will get your chance.

 

                It is a process question.

 

                DR. NEWMAN:  This is a process question.

 

      It seems to me it might not be a good use of time

 

      to go around the table and have everybody comment

 

      on it.  I mean I just think they did a great job,

 

      we should praise them, and move on to some more

 

      substantive issues that are important.

 

                DR. GOODMAN:  You stole my words, now what

 

      am I going to say.  I do like to go around the

 

      table even if the comment is ditto, just to give

 

                                                               170

 

      everybody a chance to speak.

 

                Let me start.  I would agree that I think

 

      that given the inherent limitations of the data, it

 

      was a very rigorous examination, very carefully

 

      planned, involved leading experts.  There was

 

      appropriate blinding, more than adequate training.

 

      We saw, too, that we had further vetting by

 

      agreement with an independent study that was

 

      conducted by the FDA in a subsample.

 

                I think there is always room for

 

      criticism, but I think most of my criticisms would

 

      be regarding the inherent limitations of the data

 

      itself, not what was accomplished by first the

 

      Columbia group and then the FDA's re-analysis of

 

      the data.

 

                So, my comments are very favorable and I

 

      can't see that there is much room for improvement.

 

      In fact, I am impressed with how much they

 

      accomplished, and I was somewhat skeptical in our

 

      last meeting, and very impressed with the outcome

 

      and attention to detail.

 

                So, let me now go around the room starting

 

                                                               171

 

      with Dr. Fant.

 

                DR. FANT:  My only comment, I agree with

 

      everything that you just said, my only comment is

 

      in the same spirit of my father, when I would come

 

      home with a 98 on my test, and he would wonder why

 

      I didn't get 100, and I guess my question to Dr.

 

      Posner is, is this scale applicable across various

 

      cultures and racial groups in terms of behaviors

 

      and actions that may be significant with respect to

 

      the endpoint that may differentiate one group from

 

      another, that may be useful in trying to explore

 

      and develop those, validate this tool in different

 

      groups?

 

                DR. POSNER:  The answer is yes, and most

 

      of the studies that these concepts are based on

 

      have a lot of heterogeneity in terms of race and

 

      general populations, so absolutely.

 

                DR. FANT:  So you feel comfortable that

 

      this tool would be just as useful in an inner city,

 

      predominantly African-American clinic, as well as

 

      one that serves Southwest Hispanic community versus

 

      one that serves Native American kids on the

 

                                                               172

 

      reservation?

 

                DR. POSNER:  I think that the definitions

 

      and the classification, the underlying concepts in

 

      the classification that were represented in what

 

      you saw yesterday, absolutely, and again were based

 

      in just those populations.

 

                In the NIMH study that I referred to

 

      earlier, for example, there is a range of all of

 

      the populations that you just mentioned, and those

 

      are exactly the kind of behaviors we are looking at

 

      and the samples that we are looking at.

 

                Again, it's overarching concepts and the

 

      behaviors are similar across all those groups.

 

                DR. GOODMAN:  Dr. Pfeffer.

 

                DR. PFEFFER:  I think this is an excellent

 

      scale  as a classification.  I think that it's a

 

      wonderful beginning and carried out with real data

 

      regardless of the quality of the data.

 

                I wanted to make some points just for

 

      clarification, and I think that is what Kelly was

 

      just pointing out, too, in a way.  This is a

 

      classification, and I don't know that one can yet

 

                                                               173

 

      extrapolate this to, let's say, use with patients.

 

                This is a secondary means of focusing

 

      individuals in terms of their behaviors or

 

      thoughts, but not yet to gather the data about

 

      them, and I think that is important to emphasize,

 

      so that much work I think needs to be done to

 

      create the kind of an instrument that could be used

 

      reliably and validly to assess directly from the

 

      patients what the nature of their thinking is and

 

      the nature of their intent, as well as the behavior

 

      itself.

 

                The other point I would like to make is

 

      that this classification does hold across all age

 

      groups generally, but in creating a method of

 

      interviewing and establishing the information, what

 

      is also necessary is to consider developmental

 

      perspective, because we do know that children's

 

      cognitive capacities of understanding the nature of

 

      their planned behaviors are quite different than

 

      adults.

 

                I will go back to the example that tends

 

      to be thrown out, and I would agree it should be

 

                                                               174

 

      thrown out, but the child who slapped herself, for

 

      example, that was one of the illustrations.

 

                You know, if you have a child that has

 

      problems or immaturity and cognition, one might not

 

      quite know what she was intending to do, and a slap

 

      or a hit with a piece of glass or whatever, it all

 

      can mean something quite different in the mind of a

 

      child, so that much work needs to be done to tease

 

      this out I think from a developmental perspective.

 

                DR. GOODMAN:  Dr. Pfeffer, I would

 

      certainly agree with your point that the

 

      assessment, the prospective assessment of the

 

      patient is a different matter, but with regard to

 

      the narrower question, as I interpret it, in terms

 

      of the classification data, the process of

 

      classification, would you have any additional

 

      comments?

 

                I think yours are more comments in terms

 

      of what would be the next steps in implementing the

 

      system, administering it to subjects in a

 

      prospective study.

 

                DR. PFEFFER:  I think the classification

 

                                                               175

 

      is excellent.  I would also raise the question, the

 

      children and adolescents who couldn't be evaluated,

 

      was it due to the data itself, was it due to

 

      questions about what category the child might fit

 

      into, which I tend to doubt because they actually

 

      solved those issues by discussions.

 

                I think, generally, this is a wonderful

 

      classification.

 

                DR. GOODMAN:  Dr. Posner, you had a

 

      comment?

 

                DR. POSNER:  I just wanted to respond to

 

      your first point, which is you are absolutely

 

      right, and all of that work has been going on

 

      simultaneously.  So, we are quite well prepared and

 

      enthusiastic actually about putting helpful

 

      assessment tools into future studies now that ask

 

      the right questions to be able to put events into

 

      these kind of categories.  So, there are two

 

      separate questions and both being addressed, I

 

      think.

 

                I think your next question has to do with

 

      our No. 3, the kids where we knew they hurt

 

                                                               176

 

      themselves, but we couldn't say why--am I

 

      correct--and the reason was because of the limited

 

      data about suicidal intent.

 

                So, these were narratives that said

 

      superficial scratch on wrist, and that's it, and,

 

      of course, not enough surrounding information to

 

      infer any kind of intent, so again, that is why

 

      that category was warranted.  This is important, we

 

      know they hurt themselves, but we just don't know

 

      why.  As the FDA told you, they put that into a

 

      worst case scenario, sensitivity analysis, which I

 

      guess looked very similar to the primary outcome.

 

                Did that answer your question about those

 

      cases?

 

                DR. GOODMAN:  Yes.  Dr. Fost.

 

                DR. FOST:  No further comment, thank you.

 

                DR. GOODMAN:  Dr. Ortiz.

 

                DR. ORTIZ:  My comments I think are more

 

      on the line of what Dr. Pfeffer had to say.  I

 

      think what Columbia has done is a wonderful start

 

      for the pharmaceutical companies to improve their

 

      identification of suicidal behaviors, and I think

 

                                                               177

 

      the FDA has done a superb job of further analyzing

 

      the 24 studies.

 

                However, the 24 studies excluded children

 

      who had suicidal ideation with the exception of 4

 

      studies, and the vast majority excluded children

 

      with history of family bipolar.

 

                So, again, my concern is in regards to the

 

      testimony yesterday that we also need to think

 

      about families and the clinician out there

 

      practicing, the pediatrician in Farmington, New

 

      Mexico, who has a mother with a 12-year-old who

 

      comes in, who says, "I want to die."

 

                I think we need to also be thinking about

 

      issues of side effects, of agitation, hostility,

 

      delusions, mania, and violence, which this

 

      particular population, I mean I think for a

 

      classification system, it is great, but there is

 

      other issues related to side effects and clinical

 

      practice that I think affect suicidality

 

      profoundly.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Malone.

 

                                                               178

 

                DR. MALONE:  I agree that the combined

 

      study was done very well, and I think it is

 

      encouraging that the original FDA study pretty much

 

      agrees with the second study, and I think gives it

 

      more validity that way.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Nelson.

 

                DR. NELSON:  I just have one comment, that

 

      I think a reasonable topic for discussion going

 

      forward by the Pediatric Advisory Committee might

 

      be to think through what lessons have been learned

 

      by this experience for the ability to compare

 

      information across different drug development

 

      programs within drug classes, because I suspect

 

      this issue might exist in other areas.

 

                So, I think that is worthy of focusing on

 

      at some point in the future, just to get that on to

 

      the docket.

 

                DR. GOODMAN:  Thank you very much.

 

                Dr. Perrin.

 

                DR. PERRIN:  I think the classification is

 

      great, and I would like to know a little more about

 

                                                               179

 

      the discordant cases between the FDA and Columbia,

 

      but I think that knowing more about the discordant

 

      cases would not change the findings at all.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Grady.

 

                DR. GRADY-WELIKY:  I agree with everything

 

      that has been said.  I would just like to follow up

 

      a bit on what Dr. Nelson said, which is that the

 

      Columbia study actually showed us a great deal

 

      about the role of narrative reporting, and I would

 

      think it is very important that we look at, for

 

      future studies, guidelines for those narratives so

 

      we have further information.

 

                DR. GOODMAN:  Thank you very much, Tana.

 

                Dr. Ebert.

 

                DR. EBERT:  I also agree, that the

 

      classification I think was reasonable, and I

 

      commend the investigators on that.  As far as the

 

      analysis, just one brief comment, and that again I

 

      think the analysis was appropriate, but again we

 

      have the caveat of the studies themselves being of

 

      somewhat questionable quality, and the variability

 

                                                               180

 

      of quality probably is hard to establish.

 

                Having said that, when the studies are

 

      analyzed, they are analyzed based on weighting

 

      those studies on their size, which therefore gives

 

      the greatest weight to the larger studies, not

 

      necessarily knowing whether those are the highest

 

      quality studies.

 

                DR. GOODMAN:  I like your last point.

 

                Dr. Gibbons.

 

                DR. GIBBONS:  Clearly, there has been a

 

      lot of excellent work done both in terms of the

 

      classification and in terms of the analyses.  I

 

      think in terms of the integrity of these data, the

 

      classification has gone about as far as you can

 

      milk the data for, and I am not sure that we really

 

      need to do much more in that regard.

 

                In terms of the analysis, I think that the

 

      analyses are very thoughtful, but I don't think

 

      they have addressed the critical question that they

 

      were intended to address.

 

                I am reading from the summary minutes of

 

      the February meeting, that "Since we are in the

 

                                                               181

 

      preliminary stages of designing an appropriate

 

      analysis of patient level data"--blah, blah, and

 

      then it goes on, the analyses that are presented so

 

      far are not really analyses of patient level data.

 

      They are combinations of risk ratios in a

 

      meta-analytic framework from study to study.  They

 

      are not patient level data.

 

                The survival analyses that were done, to

 

      some extent, are patient level analyses, but those

 

      analyses are not adjusted for the effects of

 

      covariates, and I really think there may be more to

 

      these data than what we have seen, and would offer

 

      that we should have a look at the data, and I would

 

      be happy to do that.

 

                DR. GOODMAN:  So, you are making a

 

      suggestion that there is opportunity for continued

 

      mining of the data, and maybe we can put that in

 

      sort of our parking lot and return to it as we get

 

      to the recommendations.

 

                DR. GIBBONS:  Yes.

 

                DR. GOODMAN:  Any comments from the FDA

 

      regarding the analytic questions that were raised

 

                                                               182

 

      just now?

 

                DR. LAUGHREN:  We would be happy to share

 

      the database, it is not a problem.

 

                DR. HAMMAD:  Regarding the fact that there

 

      is no apparent patient level data, examining the

 

      confounding on trial level was done based on the

 

      patient level data, and also, as you said, time to

 

      event also utilized the patient level data.  Also,

 

      examining the interaction in all trials by the

 

      certified analysis used the patient level data, but

 

      there might be some other things to be done putting

 

      everything together.

 

                DR. GIBBONS:  I don't have necessarily any

 

      expectation that a different analysis would yield a

 

      different result, and I don't have any criticism of

 

      the analyses that have been done.  In fact, given

 

      the time frame that were available, you have gone

 

      way beyond any of my expectations, but I do have a

 

      few ideas of how the data could be analyzed in a

 

      different way, that might shed a slightly different

 

      light.

 

                DR. GOODMAN:  Thank you.

 

                                                               183

 

                Dr. Pine.

 

                DR. PINE:  Beyond the general comments

 

      about the outstanding nature of the work, I guess I

 

      would make only one other comment, and that relates

 

      to some discussion between the last meeting and

 

      this meeting, about the degree to which these

 

      analyses were necessary or appropriate, and I guess

 

      I would only just speak for myself to say that I

 

      found them both helpful and in some ways necessary

 

      to really inform on the next question that we are

 

      going to deal with.

 

                Again, just speaking for myself, I feel

 

      far more comfortable being able to talk about the

 

      second issue concerning is there or is there not a

 

      signal, having seen the outstanding quality of the

 

      work that was done.

 

                DR. GOODMAN:  Jean Bronstein.

 

                MS. BRONSTEIN:  I have nothing further to

 

      comment about the study although I really thought

 

      the analyses done with Columbia really helped me

 

      better understand this issue than I did in

 

      February.

 

                                                               184

 

                I do at some point want to speak about

 

      warnings and what I heard from yesterday's

 

      testimony, and I think it really comes under the

 

      next question rather than this one, so I will hold

 

      that for then.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Rudorfer.

 

                DR. RUDORFER:  I would like to second the

 

      excellent quality of the classification project.  I

 

      wonder if there is room to more formally include

 

      informant information.

 

                I am thinking particularly in some of the

 

      coding, which have been described as softer, for

 

      instance, suicidal ideation, should there be a

 

      subcategory of suicidal ideation that is validated

 

      by a family member as having been expressed as

 

      opposed to just expressed by the patient.

 

                DR. POSNER:  Ideation is not typically one

 

      of the categories that you would feel even the need

 

      to be validated by a family member, because it is

 

      what is going on in their head, so usually, the

 

      most valid indicator of it is the child or

 

                                                               185

 

      adolescent.

 

                I understand what your comment is in the

 

      narrative.  Some of the narratives said, you know,

 

      mom said that he said this, or the doctor just

 

      said, you know, indicated what was said, but there

 

      is no way to further break that down at this point

 

      with the limited information that we have.

 

                Again, I think it becomes more relevant

 

      just from our assessment standpoint in terms of

 

      behavior than ideation, having the supplementary

 

      informants.

 

                DR. RUDORFER:  Thanks.  The only other

 

      thing I would add is just to re-emphasize--and

 

      again this is not a problem with the

 

      classification, this was a problem with the

 

      underlying data--that your outcome was only as good

 

      as the data that were available, and I think we are

 

      all faced with that conundrum that those data seem

 

      to be rather incomplete and inconsistent.

 

                DR. POSNER:  It is true, but I wanted to

 

      highlight, in your handouts, you see the first

 

      example I gave yesterday of the suicide attempt

 

                                                               186

 

      that was clinically impressive, where the patient

 

      took 100 pills, you have a very detailed narrative

 

      in your handouts.

 

                It is important to note that every one of

 

      these narratives, many of the narratives had a lot

 

      of supplementary information, and that was what was

 

      so crucial about having suicidal experts, because

 

      they can take all of that supplementary information

 

      and say, yeah, this looks like a suicide attempt

 

      given everything that we have.

 

                So, I just think it is important to

 

      highlight that there was a significant amount of

 

      surrounding information even though stated intent

 

      was very often not there.

 

                DR. RUDORFER:  Right.  No, I appreciate

 

      that, and I commend you for that.  My concern

 

      remains with, say, the placebo-treated subject who

 

      walks in and verbalizes no complaints, and then the

 

      rating process goes on and no one ever discusses

 

      any surrounding issues because there doesn't seem

 

      to be any cause for it.

 

                DR. POSNER:  Right, we can never make

 

                                                               187

 

      sense of something that is not there.

 

                DR. RUDORFER:  Right.

 

                DR. GOODMAN:  I have already rendered my

 

      opinion, I will just add by saying that I was not

 

      prepared to answer Question 2 at the last meeting,

 

      but I am now based upon the reclassification.

 

                Dr. Chesney.

 

                DR. CHESNEY:  The good news is that I have

 

      no further comments about the analyses other than

 

      what the rest of the panel has said.

 

                I was struck yesterday, as I was in

 

      February, by the reports of the parents of a number

 

      of children who never expressed suicidal behavior

 

      or ideation, and yet proceeded to commit suicide,

 

      and my second point has to do with other injurious

 

      behavior.

 

                We have looked at self-injurious behavior,

 

      we have looked at obviously suicidal, but we

 

      haven't looked at aggression, hostility, all of

 

      those aspects of the activation syndrome that we

 

      talked about in February.

 

                The thing I feel relatively good about,

 

                                                               188

 

      however, is that I think, had we looked at those,

 

      it would have only strengthened the results that we

 

      have already seen, so those are my only comments.

 

                DR. GOODMAN:  Thank you.

 

                Dr. McGough.

 

                DR. McGOUGH:  I just agree with the

 

      Chair's comments.

 

                DR. GOODMAN:  Ms. Griffith.

 

                MS. GRIFFITH:  I would endorse that, too,

 

      and I agreed with Dr. Gibbons that the

 

      classification has gone about as far as it could,

 

      but I have a very quick question for Dr. Hammad,

 

      because at the February meeting, you raised the

 

      possibility that the data might not be robust

 

      enough to render any conclusions, and your

 

      formidable presentation yesterday, I suspect gives

 

      you confidence, but I would just like to know if

 

      you, indeed, feel that this is robust enough.  I am

 

      asking you a very subjective question, I am sorry

 

      to put you on the spot.

 

                DR. HAMMAD:  Yes, you are right, it is

 

      subjective. Of course, it depends on what do you

 

                                                               189

 

      mean actually by "robust" here.  I think if you

 

      look at the individual trials, for example, you

 

      feel that there is nothing going on, there is

 

      nothing significant on its own, but when you see

 

      how consistent the signal is coming from most

 

      trials, putting this in the context of what the

 

      rest of the process is, which is the fact that we

 

      know now we have every event that is out there, as

 

      well the public testified, and you still see it,

 

      then, you can feel more comfortable about the

 

      findings.

 

                So, I agree with the comment that were

 

      said before about the level of comfort that is

 

      definitely much better than it was in February.

 

                Also, the sort of things like the

 

      information we have on discontinuation, for

 

      example, also about the history of seratin [?], I

 

      mean these two factors alone could have made the

 

      results one way or the other, and if we did not

 

      have information about those, and we had not tested

 

      them, we would have spent a long time trying to

 

      speculate how much actually impact we have.

 

                                                               190

 

                So, we also got this out of the way, the

 

      obvious, clear potential explanation for the

 

      apparent risk.  So, I think what we are saying now

 

      is true.

 

                MS. GRIFFITH:  Thank you.

 

                DR. GOODMAN:  Dr. Leslie.

 

                DR. LESLIE:  I just want to say thank you

 

      for the work you did.

 

                DR. GOODMAN:  Dr. Robinson.

 

                DR. ROBINSON:  In terms of classification,

 

      I just want to second what most of us have said,

 

      which is that I think the FDA and the Columbia

 

      group did as good as they can with the data that

 

      they had.

 

                Just two comments.  One is that in terms

 

      of going forward, and Dr. Posner might obviously

 

      have ideas about this, is that the Columbia

 

      classification was obviously done in terms of what

 

      you could get out of very limited data, and in the

 

      future, sort of going forward in a prospective sort

 

      of manner, you might have a different

 

      classification or you might have a scale that had

 

                                                               191

 

      additional items which might be very important,

 

      which you couldn't get from retrospective data.

 

                So, I think we still need to think about

 

      that you can, for prospective studies, do something

 

      maybe that is even better.

 

                DR. POSNER:  I just want to clarify one

 

      thing, and it is a very important point.  This

 

      classification scale and scheme really is about

 

      concepts and definitions, so we defined, suicidal

 

      attempts were defined like this.  We took the data

 

      and put it into that category using that

 

      definition.

 

                Then, there are the measures that you use,

 

      the tools, to ask the questions to ascertain that

 

      information to be able to know whether that

 

      definition applies.  So, we do have those measures

 

      and tools that aid in this classification that will

 

      hopefully inform all of the studies going forward,

 

      as you are pointing out.

 

                So, the whole system really involves two

 

      elements, right, the tools in which people and

 

      clinicians and industry need to use to ask these

 

                                                               192

 

      questions of these patients and families to find

 

      out whether or not, where they go in this

 

      classification scheme.

 

                Does that clarify it somewhat?

 

                DR. ROBINSON:  Yes, but, for example, like

 

      in preparatory acts, you have preparatory acts

 

      where the person stops themselves versus somebody

 

      else stops themselves, and often from a clinical

 

      point of view, you know, it is like my child had

 

      the rope up and I saw them and I stopped them, as a

 

      clinician, that has a very different thing than

 

      somebody saying, well, I was going to do this, and

 

      I got the gun out, but then I told myself, no, that

 

      is wrong, and I went to my family.

 

                Again, for going forward, you might make

 

      some refinements.  I am just saying not necessarily

 

      have this set in stone, because this is obviously

 

      done for something that is sort of retrospective.

 

                DR. POSNER:  But what I am saying is we

 

      have an assessment tool, for example, where all of

 

      those questions, the clinician has those questions

 

      in front of them, so have you ever done anything to

 

                                                               193

 

      hurt yourself where you wanted to die, have you

 

      ever started to do something and stopped yourself,

 

      and then they get that information with those

 

      definitions and the probes and the questions, and

 

      then they can then go and decide there was a

 

      preparatory behavior or there was a suicide

 

      attempt.

 

                So, all of those distinctions and

 

      questions and helpful aids, we have certainly been

 

      working on and intend to hopefully distribute and

 

      even have guidelines and training days, so that

 

      people can start to use these in their studies.

 

                I just wanted to add to two comments I

 

      heard about we have to look broader at more of the

 

      other symptoms that we are talking about and

 

      worrying about, like akathisia, agitation, and

 

      aggression.

 

                The study that I keep talking about, for

 

      example, the Adolescent Suicide Attempter study,

 

      that is NIMH-sponsored, we are working very hard on

 

      measures and tools to look at all of these side

 

      effects that are associated possibly with SSRIs

 

                                                               194

 

      including all of those things - how to ask the

 

      questions, how to collect it, so hopefully, we can

 

      have tools and we can also answer some of these

 

      related questions.

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  I would agree that the

 

      reclassification and analysis were both clinically

 

      and scientifically appropriate.  I found them to be

 

      rigorous.  I was impressed with the blinding

 

      procedures and would echo the thought for future

 

      randomized, controlled trials, in conjunction with

 

      the FDA, that there be some type of standardized

 

      classification that is mandated across all studies.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Irwin.

 

                DR. IRWIN:  I agree and I would just like

 

      to second what Dr. Chesney raised in terms of the

 

      issues of aggression and violent behavior.  They

 

      don't seem to be a part of this instrument right

 

      now.  Thanks.

 

                DR. GOODMAN:  Ms. Dokken.

 

                MS. DOKKEN:  I agree with the intent of

 

                                                               195

 

      the previous comments.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  I do, too.

 

                DR. GOODMAN:  Dr. Wells.

 

                DR. WELLS:  I think we have done about as

 

      well as we can do with the reclassification and

 

      with the re-analysis.  We recognize, of course,

 

      that the data aren't perfect, having largely to do

 

      with how they were elicited.

 

                I don't think that there is very much more

 

      that we can do with the data, although there may be

 

      a little bit more.  I recall that Dr. Mosholder,

 

      for instance, had recommended that we might want to

 

      do an analysis using inpatient hospitalization as a

 

      primary outcome and see what is picked up there.

 

                We remain troubled by the inconsistencies

 

      across the studies, even for specific drugs, we

 

      don't understand what accounts for those

 

      inconsistencies, but I think at this point, we need

 

      to move forward and see if there is some decisions

 

      that we can make with the data that we have.

 

                DR. GOODMAN:  Thank you.

 

                                                               196

 

                Dr. Pollock.

 

                DR. POLLOCK:  Yes, it's a question was

 

      there ever or is there any plan for this kind of

 

      patient level, at least to sample, because of the

 

      concerns about ascertainment in the adult studies,

 

      if there was any contemplation or has there been

 

      any probing at all of the quality of that data.

 

                I mean we have some confidence in your

 

      overall conclusion, but we don't have confidence,

 

      or at least the public doesn't have confidence for

 

      some of those adult studies, what was actually

 

      recorded, and if it might be certainly in the

 

      public's interest to conduct at least a quality

 

      sampling using the same methodology in the adult

 

      studies.

 

                DR. LAUGHREN:  As I indicated yesterday,

 

      right now our focus is on the completed suicides

 

      that we have in this very large database, and we

 

      can consider this second issue, but I think right

 

      now we are going to try and finish up with looking

 

      at the completed suicide data.

 

                DR. GOODMAN:  Dr. O'Fallon.

 

                                                               197

 

                DR. O'FALLON:  I agree with what has been

 

      said by the rest of you, I am not going to argue

 

      with any of you, but I am still--I think there are

 

      a couple of issues here.

 

                One of them is that I don't think that

 

      this re-analysis has done very much about looking

 

      at that question about the association between

 

      adverse events and dose changes.  I think there may

 

      have been problems.  At least I didn't see very

 

      much about that.  Maybe I was missing it.

 

                I think I am still very concerned about

 

      the possibility that we might be underestimating

 

      the incidence of these adverse events, the suicidal

 

      ones.  I am afraid of it because if we get the

 

      answer wrong, we could have a very bad effect upon

 

      medical practice.  That is always the issue here

 

      with doing research.

 

                Obviously, there wasn't very much power to

 

      detect, I mean it's a rare event, thank God it's a

 

      rare event, suicidality, but there isn't a whole

 

      lot of power to pick it up under the best of

 

      circumstances even with the meta-analysis.

 

                                                               198

 

                I think I have asked this question twice,

 

      and I think the FDA needs to address upfront the

 

      charges that I heard over and over again that the

 

      FDA doesn't have all the data, that somehow or

 

      another the companies are holding back data or

 

      suppressing it from you.

 

                I think that is something that has to be

 

      made clear to the public.  You have said no, if

 

      they put in an application, we get every shred of

 

      data they ever had even if it was 25 years old.

 

      But there is a perception out there that I think

 

      the FDA has to address.

 

                DR. GOODMAN:  I am not sure if those

 

      comments are germane to the question at hand.  You

 

      may want to hold them for later.

 

                DR. O'FALLON:  Okay.

 

                DR. GOODMAN:  Dr. Santana.

 

                DR. SANTANA:  I also agree that clinically

 

      and scientifically, you have done the best that you

 

      can with the data that you have.  I do want to move

 

      forward, though.  I mean this classification system

 

      is an event-based, outcome system, but it really

 

                                                               199

 

      doesn't get to the issue that I would have if I was

 

      a practicing physician in this area, which is, is

 

      this toxicity or is this lack of response, does

 

      that lead to that common outcome.

 

                So, as you develop your new tools, your

 

      new questionnaires, whatever you are going to do to

 

      validate this classification and take it forward to

 

      new studies, I would want you to pay some attention

 

      to try to dissect how that common outcome is

 

      related to either toxicity or lack of response,

 

      because I think that would be important and would

 

      address some of the issues that the parents and

 

      families had, you know, that they were attributing

 

      it to toxicity, whereas, some of us may interpret

 

      that it actually was a lack of response.

 

                DR. GOODMAN:  Thank you very much.

 

                Dr. Wang.

 

                DR. WANG:  I agree these were very strong

 

      process and results.  I do have two small

 

      suggestions to bound the lingering questions we

 

      have about case ascertainment.  The first is how

 

      many cases may have been missed by the sponsor's

 

                                                               200

 

      screen and never sent, and for that, you might

 

      consider an audit of what was not sent, you know, a

 

      sample of that.

 

                The second is the potential ascertainment

 

      bias due to this unblinding by side effects, and

 

      you could check for this by seeing whether an

 

      adverse event known to be unrelated to

 

      antidepressants was elevated in the antidepressant

 

      versus placebo arms.  It would just at least give

 

      us a sense of the potential magnitude of either of

 

      these two problems.

 

                DR. GOODMAN:  Dr. Gorman.

 

                DR. GORMAN:  I would like to echo the

 

      generally positive comments about the

 

      reclassification as being helpful to especially

 

      myself to understand the data, and that would then

 

      lead to a compliment to the Office of Drug Safety

 

      both at the global level and the individual level

 

      for recognizing the signal through all the noise

 

      when the data was not classified in a way to make

 

      it as clear to them as it is now to us.

 

                The ascertainment of the cases, I think

 

                                                               201

 

      would make the signal stronger in general.  I think

 

      all the errors we are worried about, in general,

 

      about how much information has been presented in

 

      the narrative, might, in fact, make the signal

 

      stronger and therefore, while I recommend to the

 

      FDA as a comment to this that I hope this

 

      classification system becomes generalized across

 

      all your therapeutic areas, that the active

 

      ascertainment for suspected or serious adverse

 

      events in all classes become active and done in a

 

      way that allows us to not be arguing whether we

 

      have got as much of the signal as there is to get.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Maldonado.

 

                DR. MALDONADO:  I just have a couple of

 

      questions, but I agree with the general consensus,

 

      and the questions are based on these tools that

 

      have been developed.  As you know, the tools are as

 

      good as the ones who use the tools. It is still not

 

      very clear to me who is going to be the end user of

 

      the tool.

 

                I actually congratulate Dr. Iyasu for

 

                                                               202

 

      doing the reproducibility and reliability within

 

      the FDA.  I am glad to see that the FDA is doing

 

      its own studies, too.  And then who are going to be

 

      the end users, is it going to be the medical

 

      officers on DDP who are going to be doing this

 

      classification, or is it going to be the requesters

 

      from the sponsors, or even primary investigators?

 

                The more you spread that, the more

 

      variability you have to expect, and then the study

 

      that Dr. Iyasu did might not be relevant depending

 

      on the user.

 

                The other thing, maybe Dr. Posner can tell

 

      us, where the publications for the validity of

 

      these questionnaires and classifications are,

 

      because again these tools are so dependent on their

 

      validity.  I am not in this field, so they may be

 

      published and people know, but I have never seen

 

      them, or maybe if they are not published, are they

 

      going to be published, so people know the validity

 

      of these two tools.

 

                I am not just referring to a

 

      classification, but also to the questionnaires that

 

                                                               203

 

      you mentioned.

 

                Thank you.

 

                DR. GOODMAN:  Dr. Mehta.

 

                DR. MEHTA:  I think the FDA has done a

 

      great job of classifying data with very poor case

 

      of confirming information.  I would go one step

 

      further, and that is, request FDA to design a case

 

      that could confirm suicidality and also together

 

      with a set of instructions, and give it out to

 

      every sponsor from now on, because I suspect that

 

      this issue we will be revisiting 10 years from now.

 

                I think Dr. Gorman and Dr. Posner also

 

      commented essentially the same thing.

 

                DR. GOODMAN:  Are you going to give the

 

      references?

 

                DR. POSNER:  No, I was just going to

 

      reiterate that we have commented many times that we

 

      are going to write guidelines just to do that for

 

      industry and everybody else.

 

                DR. GOODMAN:  We can't hear you.

 

                DR. POSNER:  I was just reiterating again

 

      that we, in collaboration with the FDA, are going

 

                                                               204

 

      to write guidelines for better ascertainment.  I

 

      think we should also have training meetings.  We

 

      discussed this yesterday.  Whatever we can do to

 

      make this consistent across everybody who is going

 

      to be doing this kind of work.

 

                DR. LAUGHREN:  Right, and that applies to

 

      both the classification and the ascertainment.

 

                DR. POSNER:  Right.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  A classification scheme like

 

      that is presumably what a company would do,

 

      probably with a special group set aside to do it in

 

      a blinded way, to evaluate the data they have got.

 

                One other observation I want to make is

 

      that one of the ways we try to focus on things that

 

      are important is to look closely at all the people

 

      who leave a study prematurely in association with

 

      an adverse reaction, and the narratives associated

 

      with that are one of the things medical reviewers

 

      look at most closely.

 

                We also get a fair sample of dropouts that

 

      were said to be for administrative reasons to see

 

                                                               205

 

      if underlying those there is actually an adverse

 

      reaction, because sometimes you want to check those

 

      things.

 

                So, that is one of the ways you go looking

 

      for things you don't know enough to expect, see

 

      what happened in those people.

 

                DR. GOODMAN:  Thank you.

 

                I want to conclude our discussion.  You

 

      can take a seat.  Thank you.

 

                There, you have our comments.  I think it

 

      is pretty straightforward.  There was a great deal

 

      of agreement that you can't imagine a better job

 

      being done given the starting point.

 

                Naturally led to discussion about what to

 

      do in the future, and I think there are some

 

      excellent suggestions there, not only for the FDA,

 

      but the field in general in terms of improving our

 

      ability to detect, ascertain suicidality and

 

      perhaps other symptoms that might be relevant and

 

      help us sort out whether we are dealing, as was

 

      said before, with toxicity versus an indication of

 

      ineffectiveness.

 

                                                               206

 

                So, I think that in the future, hopefully,

 

      we will be ascertaining and classifying these data

 

      in a prospective fashion, and obviously, a lot of

 

      the details need to be worked out about who will be

 

      doing what part of that job.

 

                With that, we should head to lunch, return

 

      at 1:00 p.m. to tackle the remaining questions.  A

 

      reminder, once again, this should be ingrained.  Do

 

      not discuss meeting questions during the lunch.

 

                Thank you.

 

                [Whereupon, at 12:02 p.m., the proceedings

 

      were recessed, to be resumed at 1:00 p.m.

 

                                                               207

 

                A F T E R N O O N  P R O C E E D I N G S

 

                                                       [1:00 p.m.]

 

                DR. GOODMAN:  Would everyone take your

 

      seats.

 

                First, a housekeeping matter.  Anuja Patel

 

      will be passing around a sign-up sheet, so that we

 

      can know if you need a taxi and at what time.  I

 

      assume you want that returned to you, Anuja, after

 

      it has made its way around the table.

 

                We are now entertaining the second

 

      question before us.  It is presented there up on

 

      the screen.  I will read it.

 

                Do the suicidality data from these trials

 

      support the conclusion that any or all of these

 

      drugs increase the risk of suicidality in pediatric

 

      patients?

 

                Now, what I would like to do is first have

 

      a discussion of the question, give you an

 

      opportunity to ask any further questions of

 

      individuals from the FDA who presented yesterday

 

      that have bearing on this question.

 

                Then, we will, following that discussion,

 

                                                               208

 

      go around and ask for your votes.  You choices are

 

      Yes, No, or Abstain, and you are permitted to have

 

      30 seconds, not much more, to explain the rationale

 

      for your vote.

 

                So, first, we are going to have a

 

      discussion.  This will be the opportunity to see if

 

      we can extract any additional information.  I also

 

      wish to point out that there are four members of

 

      the committee at the table who are non-voting

 

      members.  We welcome them to participate in the

 

      discussion phase, but obviously, will not be

 

      participating once the vote commences.

 

                Their names are Dr. Mehta, Dr. Maldonado,

 

      Dr. Gorman, and Dr. Wang.

 

                In posing this question, I had a few

 

      comments, and maybe a question to the FDA in terms

 

      of clarification.

 

                First, I had mentioned earlier that there

 

      is some lack of clarity about the definition of

 

      suicidality.  In fact, as we can see on the other

 

      screen, although there is quite clarity there, you

 

      can set the brackets either narrowly or broadly in

 

                                                               209

 

      terms of what we mean by suicidality.

 

                For the most part, in the analysis that

 

      was presented yesterday, the definition of

 

      suicidality corresponded to Outcome 3, which

 

      included evidence of suicide attempt, preparatory

 

      actions or suicidal ideation.

 

                So, I think before we take a vote on that

 

      question, there should be some discussion and maybe

 

      some guidance from the FDA, as well, is which

 

      definition of suicidality are we adopting for the

 

      purpose of that vote.

 

                Second, I wanted to note that if we are

 

      basing the information exclusively on the clinical

 

      trials, as stated explicitly in the question, we

 

      have no instances of suicide, so we would not be

 

      concluding anything about suicide, only the risks

 

      of suicidality, not completed suicide.

 

                My feeling is--again, I pose this to the

 

      FDA--we cannot ignore the other information we

 

      heard from the public testimony about cases of

 

      completed suicide, and obviously, those are not

 

      from the trial, yet we can in some ways extrapolate

 

                                                               210

 

      from the ideation and behaviors in the trials to

 

      the risk of completed suicide that perhaps would

 

      exist in the absence of a carefully controlled

 

      environment, such as is the case in a clinical

 

      trial.

 

                So, maybe I could start by posing the two

 

      questions to the FDA.  One has to do with which

 

      definition of suicidality should we be

 

      entertaining, and, secondly, should we limit this

 

      answer to what we know from the clinical trials.

 

                DR. LAUGHREN:  Our intent was that you

 

      focus on Outcome 3.  That was our primary endpoint

 

      in the trials, so that is what we intended by

 

      suicidality.  I think for the purposes of this

 

      question, we would like you to focus on the

 

      clinical trials.

 

                I mean you can subsequently address data

 

      from other sources, but we are primarily interested

 

      with regard to this question on the clinical

 

      trials.  I agree with you that it applies to

 

      suicidality, not completed suicide, because

 

      obviously, there weren't any completed suicides in

 

                                                               211

 

      these trials.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  The difficulty in dealing

 

      with the question of completed suicides is that

 

      while, unquestionably, some of the cases reported

 

      sound pretty interesting and persuasive on the

 

      point, you have no idea how persuasive the decrease

 

      in suicide that other people alleged, how large

 

      that is.

 

                So, how to say whether there is a net

 

      benefit or harm on completed suicides certainly is

 

      unclear to me.  Those data are very hard to analyze

 

      quantitatively.  That is not the same as saying

 

      that some people don't seem to get worse when they

 

      are on these drugs, but some people seem to get

 

      better also.  So, how to put that in numbers that

 

      addresses that question, increasing, say, the risk

 

      of suicide, that seems very hard to do.

 

                DR. LAUGHREN:  I guess another

 

      qualification here is that obviously, this is a

 

      very small window in time that we are looking at.

 

      These are short-term trials.  I think it has to be

 

                                                               212

 

      focused on that window in time for which we have

 

      data.  I mean in my view, that is really the

 

      question.

 

                DR. GOODMAN:  Other comments from the

 

      committee?

 

                Dr. Nelson.

 

                DR. NELSON:  The question I had, let me

 

      just be clear, because I think might have been

 

      answered by your response, because the way the

 

      question is framed doesn't say anything about the

 

      timing of the suicidality and some of the

 

      discussions of early versus late, and questions of

 

      late decreases, et cetera.

 

                So, by restricting the answer to this

 

      question to the data at hand, the way I would

 

      interpret it is it is to speak directly to the

 

      early possible increase in signal that is seen, not

 

      to the broader questions, which then would come in

 

      to play perhaps in tackling Question 4, where the

 

      risk-benefit becomes an issue.

 

                So, I state that as a comment, I guess, in

 

      order to make sure that I am interpreting what you

 

                                                               213

 

      have said correctly, because I was going to ask

 

      about how this would be focused on the early versus

 

      late kind of issue that has been part of this

 

      discussion.

 

                DR. GOODMAN:  Dr. Ebert.

 

                DR. EBERT:  Just another clarification for

 

      my purposes, and when we talk about this, I am

 

      assuming we are talking about an increasing risk

 

      compared with placebo as opposed to an absolute

 

      increase in risk, because obviously, that would

 

      also take into account the potential efficacy of

 

      the drug.

 

                So, in fact, we might be, if the drug is

 

      efficacious, seeing a net reduction in suicidality,

 

      but we are talking here about comparing it with a

 

      placebo.

 

                DR. GOODMAN:  I would agree with that

 

      interpretation.

 

                Dr. Irwin.

 

                DR. IRWIN:  Is there a word suicidality?

 

                DR. GOODMAN:  Every time I write it in

 

      Word, it gets red underlined.

 

                                                               214

 

                DR. IRWIN:  It seems to me, I mean to me,

 

      I am not certain anyone really knows what it is

 

      that we are saying and what you are voting on, or,

 

      to me, I would like to know what suicidality is.

 

                DR. GOODMAN:  I don't think it is in an

 

      Oxford Dictionary either.

 

                MS. GRIFFITH:  It is not in Webster's.

 

                DR. IRWIN:  In a sense, it confounds

 

      things by, you know, the front page of the paper

 

      today, I think may lead to kind of a

 

      misrepresentation.

 

                DR. POLLOCK:  Can't we just use the

 

      explicit language?

 

                DR. GOODMAN:  That is, in part, what I

 

      would favor, is that if we use it, I think we need

 

      to at least parenthetically define what we mean

 

      when we are answering the question.

 

                Dr. Temple.

 

                DR. TEMPLE:  Yes, that is what we do.  I

 

      think that is what we actually did in labeling.

 

      Whether we should coin a new word is debatable,

 

      obviously, but it means suicidal behavior plus

 

                                                               215

 

      suicidal ideation.  That is what we use it to mean

 

      as those items.

 

                DR. GOODMAN:  Would it be fair for us to

 

      slightly modify the question, or do we have to take

 

      it as it is, because what I would say, if we could

 

      use the definition that corresponds to Outcome 3, I

 

      would feel most comfortable, because that

 

      corresponds to the reclassification and the way you

 

      approach the dataset.

 

                So, suicidality, suicide attempt,

 

      preparatory action/or suicidal ideation.

 

                DR. KATZ:  Yes, you can certain amend the

 

      question.  We called it suicidal behavior and

 

      ideation, but it is clearly what is embodied in

 

      Codes 1, 2, and 6.

 

                DR. GOODMAN:  I think we have a

 

      clarification on that and hopefully, the public

 

      will understand what we mean, too, and that, I

 

      think we will leave it to the press to do their job

 

      in trying to best define what we mean and don't

 

      mean by that term, specifically, that we are not

 

      talking about actual completed suicide if we are

 

                                                               216

 

      restricting our deliberations to the clinical

 

      trials, because there weren't any instances.

 

                Dr. Perrin.

 

                DR. PERRIN:  I would like to ask a related

 

      question to help me understand how to approach this

 

      vote, which is really not the analysis, but the

 

      trials themselves and some I think fairly brief

 

      questions.

 

                My understanding from reading the reviews

 

      in Dr. Dubitsky's presentation yesterday, and from

 

      Dr. Hammad's review, that these are very diverse

 

      populations in these trials, only variably well

 

      described, so we don't really know what percentage

 

      of these young people actually had major depressive

 

      disorders even in the MDD trials.

 

                We know very little about comorbid or

 

      co-existing conditions in them.  Although they

 

      describe what the inclusion/exclusion criteria are,

 

      we know relatively little about the concomitant

 

      treatments for them.

 

                Again, as I read the descriptions, they

 

      are a lot of drugs that they might have been on

 

                                                               217

 

      were excluded, on the other hand, about

 

      three-quarters of all the samples were on some

 

      concomitant treatment of some sort or other.

 

                So, I take it, if I am reading this right,

 

      a very diverse, hard to consider similar

 

      populations across the multiple trials, which might

 

      be the explanation for why nefazodone had

 

      absolutely no events in 450 subjects.

 

                I am really asking the question, am I

 

      right in this reading, and, if so, because that

 

      would help me understand more about the strength of

 

      the signal given incredibly diverse samples.

 

                DR. GOODMAN:  Perhaps Dr. Dubitsky, is he

 

      here, could answer that.

 

                DR. DUBITSKY:  I am not quite sure how to

 

      even begin.  It is a very complex question, and it

 

      is very relevant.  The diagnostic criteria did span

 

      anywhere from DSM-III up to DSM-IV, including

 

      DSM-IIIR, but beyond that, I think as I alluded to

 

      yesterday, you know, some studies did use more

 

      extensive diagnostic screening procedures, and it

 

      is to me very unclear as to what role that may have

 

                                                               218

 

      played in creating some diversity among the trials.

 

                I think you mentioned the issue of

 

      concomitant treatments, and it is true that most of

 

      the patients did receive some kind of treatment, be

 

      it something as simple as aspirin or another

 

      antidepressant during the trial.

 

                I think, in general, the treatment with

 

      concomitant antidepressants other than the study

 

      drug was fairly rare, but you can go on from there,

 

      because you do have antipsychotics and all kinds of

 

      other non-psychotropic medications, non-psychiatric

 

      medications that do have psychotropic effects, and

 

      it becomes very, very complex trying to sort that

 

      out in terms of what the medication was, what the

 

      actual psychotropic effect was, what the timing

 

      was, how that may have influenced the outcome of

 

      interest.

 

                So, I don't have a good answer for that.

 

                DR. GOODMAN:  I think there were some

 

      differences you pointed out and the degree of

 

      structured interviews that were conducted, so that

 

      may account for some heterogeneity.

 

                                                               219

 

                I think even if the criteria were uniform,

 

      the inclusion/exclusion criteria were uniform

 

      across the studies, which they weren't, I do think

 

      there is a great deal of heterogeneity, which has

 

      to do with the limits of our ability to

 

      characterize major depression in children.

 

                DR. PERRIN:  In that context, I think it

 

      is also, we have heard the real difficulties in

 

      distinguishing major depression and bipolar

 

      disorder in these populations.

 

                I guess the point that I think you are

 

      supporting is very diverse populations,

 

      nonetheless, a very persistent signal despite very

 

      different populations.

 

                DR. DUBITSKY:  I think it is quite

 

      possible that the population was very

 

      heterogeneous.  Again, to what extent that is

 

      actually the fact, I don't really know, but there

 

      is a distinct possibility.

 

                DR. GOODMAN:  Thank you.

 

                I want it to be clear and make sure that

 

      we all agree at this point and understand that as

 

                                                               220

 

      we answer this question, we are restricting our

 

      data to the clinical trials.  I think that is the

 

      intention of the FDA.  I think that is reasonable

 

      as long as we understand which question we are

 

      asking.

 

                We are not asking the broader question

 

      based upon other data that has been brought to our

 

      attention, strictly what can be gleaned from the

 

      clinical trial data.

 

                But I will entertain any discussion of

 

      that point.

 

                MS. BRONSTEIN:  As I listened to the

 

      reports on the studies and also listened to the

 

      public testimony, I think some of the public

 

      testimony really highlights the necessity to look

 

      carefully at the trials.

 

                The public is asking us very succinctly to

 

      warn them, and I think we have done some since last

 

      February, and I think we need to even do more in

 

      the way of maybe even informed consent and using

 

      family members as partners even more than we have

 

      in the past.

 

                                                               221

 

                But I want to harken on what Nami talked

 

      about a little bit yesterday and some of the

 

      clinicians that spoke.  I am most concerned about

 

      access for children to all of the kinds of things

 

      that are available even with the known risks.

 

                I guess, as somebody who is very concerned

 

      about the consumer, I really want to focus on what

 

      the signal is in terms of giving warning, not

 

      necessarily restriction.

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  I certainly agree with,

 

      for example, the next question focusing on the

 

      clinical trials, that really is a clinical trial

 

      question of what we know from the current data.

 

                I think when we get to broader questions,

 

      for example, should these antidepressants be

 

      contraindicated in children, I think it is almost

 

      impossible to address that question without

 

      bringing in a broader database beyond the current

 

      clinical trial.

 

                DR. GOODMAN:  I think that is a fair

 

      statement.

 

                                                               222

 

                I want to make sure before we try to

 

      answer the question that we are clear about the

 

      question.  I think we are at this point.

 

                Any further clarification needed?

 

                [No response.]

 

                DR. GOODMAN:  Dr. Newman, I think you

 

      wanted to add a little bit to our dataset.  I will

 

      give you an opportunity to do that.

 

                DR. NEWMAN: I made a slide during lunch.

 

      If I could have the pointer, too.  When the FDA

 

      staff presented the results of the pooled analysis

 

      of the clinical trials, what they presented were

 

      the relative risks and the 95 percent confidence

 

      intervals, and although if you have a lot of

 

      practice, you can look at those confidence

 

      intervals and see what the p-value is, that does

 

      take some mental arithmetic.

 

                It is kind of hard to do those logs in

 

      your head.  So, these are the four risk ratios.

 

      They are all about two, meaning that people who

 

      were assigned to SSRI treatment in these trials had

 

      about double the risk of these suicidality events,

 

                                                               223

 

      and these are the lower and the upper 95 percent

 

      confidence intervals, and the p-value is sort of

 

      the measure of the strength of the signal meaning

 

      how, if SSRIs did not cause suicidality, how often

 

      would you see a signal this strong or stronger.

 

                Just to show you that my little

 

      spreadsheet way of doing it works for the people

 

      who know some statistics, if the 95 percent

 

      confidence interval just exactly hits 1, the lower

 

      limit, then, that means the p-value is 0.05, which

 

      it is here or reasonably close.

 

                You can see that the p-value, that is the

 

      chance of observing a signal this strong or

 

      stronger, the highest one is about 0.04, and this

 

      one here, which is the lowest p-value, because the

 

      sample size is the biggest, because we are looking

 

      at the possible events, as well as the definite

 

      ones.  This is Outcome 4, and in all the trials,

 

      not just the MDD trials, is about 5 in 100,000, so

 

      this is a signal strength that would occur by

 

      chance about 1 in 20,000 times.

 

                I think this is important because many of

 

                                                               224

 

      the concerns that have been expressed by members of

 

      the committee would be to a loss of power, they

 

      would lead to we are not capturing all the

 

      suicides, we are not sure that all we have is

 

      suicidality, and heterogeneity, and maybe they

 

      didn't even have the right disease and sloppiness,

 

      all of those would tend to make the p-value higher.

 

                So, I actually think the way the question

 

      is phrased, which is does it support the conclusion

 

      is actually a little bit weak.  I think we could

 

      phrase the question, it would be much stronger

 

      about the data.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Nelson.

 

                DR. NELSON:  Thank you for doing that, but

 

      I got the impression yesterday when you suggested

 

      that, that a little statistical skirmish broke out,

 

      so I am interested in hearing from the other

 

      statisticians around the table just what they think

 

      of this approach.

 

                DR. NEWMAN:  Actually, I talked to Dr.

 

      Hammad ahead of time.  Did you want to comment? 

 

                                                               225

 

      Okay.  If the other statisticians would like to

 

      look at this, or I could open up the spreadsheet

 

      and show them, but I really, I don't view this as

 

      controversial.  If there are people that do, then,

 

      I would like to hear from them.

 

                DR. GOODMAN:  Dr. Gibbons.

 

                DR. GIBBONS:  The computation is based on

 

      the fact that these are asymptotic confidence

 

      intervals, that is, you are assuming large sample

 

      theory and assuming normality of the risk ratio,

 

      and that is how Dr. Hammad did the computation, so

 

      the probability values fall directly out of it.

 

                Of course, it makes sense that when you

 

      are right on the boundary of 1, the probability

 

      should be 0.05 or close to it based on the 95

 

      percent confidence of the asymptotic normal limit.

 

                So, these p-values are reasonable, but be

 

      careful about p-values.  One of the reasons why

 

      people use confidence intervals is to describe an

 

      effect size, and a very small difference in an

 

      effect size in a large sample will give you a

 

      probability value that is very, very tiny.

 

                                                               226

 

                So, don't interpret the difference between

 

      0.05 and 5 times 10                                                      

       -5 as being a huge difference in

 

      effect size, but at the same time, if you are

 

      worried about things like multiple comparisons,

 

      like, hey, they went out and did a bunch of tests

 

      and some of these are probably happening by chance

 

      alone, you look at a value of 10                                         

                                          -5, you can do an

 

      awful lot of comparisons.

 

                We are all born with a fixed number of

 

      degrees of freedom, and if you use them up too

 

      quickly, you die a painful death, but that protects

 

      you pretty well.

 

                DR. GOODMAN:  Thank you very much.  That

 

      is the best explanation I have heard of that yet.

 

      Thank you.

 

                Other committee members?  Dr. Katz.

 

                DR. KATZ:  I just want to comment on the

 

      last comment.  It is true, I suppose, that 5 times

 

      10                                  -4 or 10-5 protects you against a lot

of multiple

 

      comparisons, but 0.04, which is the p-value, the

 

      normal p-value for Outcome 3 for SSRIs and MDD, and

 

      we haven't yet gotten to the point to which a

 

                                                               227

 

      population should any conclusion apply, but the

 

      0.04, in the face of lots of multiple comparisons

 

      perhaps is a different kettle of fish.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Tom, maybe a follow-up.  As

 

      far as the p-values go, if I humbly understand it,

 

      you know, worrying about Type 1 error, we are

 

      worrying about calling something different when it

 

      is not, but I think the problem is the other way.

 

                I mean I am more concerned of missing

 

      something that is there.  I am more concerned about

 

      Type 2 error, and is there any light to be shed on

 

      that, or are we just comfortable enough that we

 

      have got a signal, we keep the signal, or is there

 

      some way we can infer if we are missing a signal?

 

                DR. NEWMAN:  The Type 2 error refers to

 

      that you have failed to find something which is

 

      really there, and I would submit that these

 

      p-values are very, very low, and so we have found

 

      it, and it is there.  When the p-value is 5 times

 

      10                                  -5, power is not the issue at all.

You had

 

      abundant, abundant power to find that because you

 

                                                               228

 

      found it with such a very, very high level of

 

      statistical significance.

 

                DR. GOODMAN:  Is there any more data that

 

      people feel they need to see before answering this

 

      question?  Again, the data from the clinical

 

      trials, not research you would like to see

 

      conducted.

 

                Dr. Pine.

 

                DR. PINE:  Just two brief comments, one

 

      related to what you just asked and another related

 

      to the other issue, and it relates to a conclusion

 

      that Dr. Laughren gave when he was summarizing his

 

      kind of directions to the committee, and that is

 

      the idea that one might use a different statistical

 

      threshold when making conclusions about safety as

 

      opposed to when making conclusions about efficacy,

 

      so while 0.05 has become kind of a magical number

 

      for whatever reason, that is usually in the

 

      discussions about efficacy, and I just wondered if

 

      he would, you know, comment if his statements

 

      really apply to this exact situation.

 

                DR. LAUGHREN:  My interpretation of the

 

                                                               229

 

      regulations is that we don't need the same level of

 

      certainty, so I think it applies directly here.

 

                DR. PINE:  Then, the only other comment I

 

      would make, and this might affect the question or

 

      it might not, and it relates to your statement

 

      about other data from other trials.

 

                As far as I know, there are no other

 

      randomized, controlled trials of SSRIs in pediatric

 

      depression.  There are other trials of pediatric

 

      anxiety disorders, and, you know, discussing them

 

      for safety right now, I know is not really the

 

      issue before the committee, but I think that there

 

      has been a hint from the analyses that have been

 

      done that perhaps the signal, so to speak, is

 

      particularly strong in children who are suffering

 

      from major depressive disorder.

 

                I would just think it would be important,

 

      if we were to go beyond major depressive disorder,

 

      to be sure to look at trials that have not been

 

      discussed, that are federally-funded trials in

 

      particular as opposed to industry-sponsored trials.

 

                DR. GOODMAN:  Dr. Temple.

 

                                                               230

 

                DR. TEMPLE:  The analyses that Dr. Hammad

 

      presented include all of the trials we know about

 

      including trials that are not in major depressive

 

      disorder, only 15 of them, or one more with TADS,

 

      and the signal, as the previous slide showed,

 

      actually looked slightly stronger when you add the

 

      trials that are not in major depressive disorder.

 

                What that means, I have no idea, but that

 

      is how the numbers sort of come out.

 

                DR. GOODMAN:  Basically, I want to echo

 

      that.  Maybe I should clarify this point.  As I

 

      understand this question, it applies to all the

 

      clinical trials, not just the major depression

 

      ones.

 

                Although the numbers were admittedly small

 

      for some of the other anxiety disorders, like OCD,

 

      they were very small numbers, but when you

 

      aggregate the data, it adds to the evidence of

 

      suicidality.

 

                DR. TEMPLE:  One of the things the

 

      committee could think about is whether some of

 

      those trials are more germane to this question than

 

                                                               231

 

      others.  The main analyses Dr. Hammad did included

 

      them all.

 

                For one thing, there is a lot of overlap

 

      in these things, and maybe the people have more

 

      than one disease, but that was the primary

 

      analysis, and there are, of course, more data, more

 

      numbers, more trials, so you have somewhat more

 

      information on those than you do on the others.

 

      Those are all good questions.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  I just wondered if before

 

      you bring this to a vote, if it is possible to

 

      rewrite this, so that we are absolutely clear what

 

      we are voting on, and it is not only--my concern is

 

      not only that you define suicidality, but also this

 

      may to some members appear redundant, but

 

      pediatric, as well, that we actually talk about

 

      clinical trials between ages of, you know, we fixed

 

      that, because the way the warning came out, at

 

      least into the field and into practice, in the last

 

      few months, was all patients, that there is a risk

 

      of increased suicidality sort of across the age

 

                                                               232

 

      spectrum, and this caused a little bit of

 

      consternation.

 

                While it is important that the efforts

 

      towards monitoring and that people be alert in all

 

      ages, where we have the evidence and where we are

 

      specifically voting, I think today is about the

 

      evidence base that we have in those specific trials

 

      conducted between certain ages, and that is where

 

      the data is.

 

                I would just again feel better if we could

 

      just frame this question very explicitly, so it is

 

      not subject to distortion.

 

                DR. GOODMAN:  I certainly agree that we

 

      should further reference what is meant by "these

 

      trials" in the question.  Perhaps this list that

 

      was supplied by Dr. Dubitsky covers it, but let me

 

      make sure that we are voting on the right set of

 

      trials, are they the ones that are listed here?  I

 

      am interested in a little bit of guidance about how

 

      to properly reference the studies.

 

                DR. TEMPLE:  It is clearly the trials we

 

      have presented to you.  They are all pediatric

 

                                                               233

 

      trials.  If you feel that you have to say that in

 

      there, go ahead and say it, but we will understand

 

      it.

 

                Those are the trials you are talking

 

      about, and the database relates to suicidality in

 

      pediatric patients, however, the warning you are

 

      referring to was quite deliberately not intended to

 

      apply only to pediatric patients, because it didn't

 

      have anything to do with whether there is an

 

      increased risk of suicidality.  That was considered

 

      good advice for any person getting these drugs.

 

      You should know that sometimes people get worse and

 

      you should monitor them closely.

 

                So, you might want to comment on that, but

 

      that was our intent.

 

                DR. POLLOCK:  It was conflated with this

 

      stuff.

 

                DR. TEMPLE:  No doubt.

 

                DR. GOODMAN:  Any other data you want to

 

      see, or discussion, before bringing it to a vote?

 

      Dr. Laughren.

 

                DR. LAUGHREN:  Just again for

 

                                                               234

 

      clarification, Question 2 is intended to follow

 

      Question 1.  Question 1 clearly states that it's

 

      the 23 plus 1, 24 trials.

 

                DR. GOODMAN:  I apologize, I wasn't paying

 

      attention.

 

                DR. LAUGHREN:  I am just pointing out that

 

      Question 2 is intended to follow directly from

 

      Discussion Point 1, which focuses on the 24 trials

 

      for which we have presented data.

 

                DR. GOODMAN:  So, you know what we are

 

      referring to, we now know what we are referring to,

 

      so I think we are okay.

 

                Ms. Griffith.

 

                MS. GRIFFITH:  But will the public know

 

      what we are referring to, and when this is

 

      extracted for the press, it better be as clear as

 

      it can possibly be.  Also, if I could just

 

      reference your web site, you need to have something

 

      very directly speaking to this and outlining it in

 

      detail on the web site ASAP.

 

                DR. GOODMAN:  Further discussion before we

 

      bring it to a vote?

 

                                                               235

 

                Dr. Pfeffer.

 

                DR. PFEFFER:  Yes, I would agree with what

 

      you just said in the sense that the question almost

 

      alludes to a generalizability, and I am not yet

 

      sure, given the discussions we had this morning,

 

      that we are fully ready to have very generalizable

 

      statements about the last part of the question,

 

      suicidality in pediatric patients.

 

                I think we have some datasets now, and we

 

      have discussed how much they have potential

 

      problems, but this is the existing data that we

 

      currently have.  So, as of today, this is our

 

      knowledge base, so to speak, and we feel from what

 

      we said this morning that we need more information

 

      ultimately and gathered in different ways.

 

                So, I am not sure we can say this is a

 

      generalizable issue yet.  So, that is the caveat I

 

      would like to address.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I am not sure what the

 

      reference to generalizability is.  This question

 

      refers to the 23 plus 1 trials and to the evidence

 

                                                               236

 

      that they do or don't provide about the risk of

 

      suicidality, defined properly, in pediatric

 

      patients who were the subject of those trials.

 

                We don't think those trials have any

 

      reference for adults.  We don't know about the risk

 

      of actual suicides, it is a fairly narrow question

 

      because those are the new data we got.  Those are

 

      the result of the pediatric trials, and the

 

      question is have they told us something.

 

                DR. GOODMAN:  I understand.

 

                Dr. Pfeffer.

 

                DR. PFEFFER:  I guess what I am trying to

 

      say is that what I mean by generalizability, I am

 

      not talking about other ages, but specifically, I

 

      don't yet think that it clarifies all pediatric

 

      patients would be at risk.

 

                DR. GOODMAN:  I don't think that is the

 

      implication of the question.

 

                DR. PFEFFER:  I am talking about the

 

      general public.

 

                DR. GOODMAN:  It means in the trials that

 

      were listed and presented to us.

 

                                                               237

 

                DR. TEMPLE:  And there could be

 

      differences among patients in the trials.  That is

 

      true for every effectiveness trial that has ever

 

      been done.  You don't know as much as you would

 

      like to.  It's in the pediatric patients that were

 

      in these studies, not all pediatric patients.

 

                DR. GOODMAN:  Tana.

 

                DR. GRADY-WELIKY:  I just wanted to

 

      comment that the amount of discussion we are having

 

      about what the question means or doesn't mean is

 

      important to at least acknowledge and, you know, we

 

      are a group of experts in this area, so when it

 

      comes to the public, I think the fact that we are

 

      struggling with it is needed to be commented on,

 

      and I would agree with Dr. Pollock that I would

 

      like to see the final version of the question

 

      before voting.

 

                DR. GOODMAN:  Dr. Katz.

 

                DR. KATZ:  I just want to get back to this

 

      question of generalizability, because we do clearly

 

      want to be able to say something at the end of the

 

      day about whether or not these results apply to any

 

                                                               238

 

      identifiable population of pediatric patients.

 

                If you were to conclude that, yes, the

 

      data show that there is an increased risk of

 

      suicidality in these specific particular pediatric

 

      patients who enrolled, but we can say nothing

 

      about, for example, pediatric patients with MDD, in

 

      general, or patients with psychiatric disorders,

 

      that would be quite problematic.

 

                Generally speaking, we do take control

 

      trial data and we convince ourselves that the

 

      results apply to some relevant population that was

 

      not studied in the trials.  If all our conclusions

 

      only applied to people in trials, we wouldn't have

 

      very much to say about drugs.

 

                So, there is a question we are asking.

 

      You can take this stepwise if you like, but we will

 

      ultimately want to know whether or not you think

 

      that these data demonstrate that there is a risk of

 

      suicidal behaviors or suicidality, as defined, in

 

      some identifiable population who in the future or

 

      who are currently being treated with the drug or

 

      drugs.

 

                                                               239

 

                DR. GOODMAN:  I don't think the main text

 

      of the question needs to be changed, but I do say

 

      that it needs to be footnoted, so that what I would

 

      suggest is that the statement--the question we are

 

      answering reads as follows:

 

                Do the suicide data from these trials--and

 

      we should put Footnote 1--as listed in--what shall

 

      we call this, Dr. Dubitsky?  Appendix A, presented

 

      by Dr. Dubitsky? Somebody give me another way of

 

      describing that.

 

                DR. TEMPLE:  You could refer to it as the

 

      23 plus 1 trials referred to in Question 1.

 

                DR. GOODMAN:  Okay, that is fine with me.

 

                So, the 23 plus 1 trials referred to in

 

      Question 1.  Somebody is bound to ask me which 23

 

      plus 1 trials those are, and those are in Appendix

 

      A listed, provided by Dr. Dubitsky.  We are getting

 

      like lawyers here.

 

                DR. MARANGELL:  All available randomized

 

      control trials in pediatrics involving

 

      antidepressants.

 

                DR. GOODMAN:  I think we are beating a

 

                                                               240

 

      dead horse, frankly.  I think we all know at this

 

      point what we are voting on, and hopefully, when it

 

      gets translated somewhere that the press and others

 

      will be attentive to exactly the appropriate

 

      references.

 

                Any other discussion?  I want to get off

 

      the question and on to information relevant to

 

      arriving at an answer.

 

                Any other discussion that we need to have

 

      before you are prepared to make your vote?

 

                If not, I am going to start, not with

 

      myself this time, I am going to start from that end

 

      of the room from my first voting member, Dr.

 

      Santana, and then I am going to remind you--yes,

 

      it's you--yes, no, you can abstain, but obviously

 

      we would encourage you to be definitive with a yes

 

      or a no, and up to 30 seconds in comment although

 

      that is not necessary, a simple yes or no would be

 

      sufficient, and we are going to be recording your

 

      vote.

 

                DR. SANTANA:  That is why I am here.  My

 

      vote is yes, and I have no further comment.

 

                                                               241

 

                DR. GOODMAN:  Dr. O'Fallon.

 

                DR. O'FALLON:  I am going to abstain.  I

 

      am looking at this data, and I don't see that clear

 

      signal that everybody sees.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  Yes.

 

                DR. GOODMAN:  Dr. Wells.

 

                DR. WELLS:  Yes.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  I would vote yes and I would

 

      even say that I think this particular question is

 

      weakly phrased to say support the conclusion, and I

 

      would also vote yes if it said do the suicidality

 

      data from these trials prove beyond a reasonable

 

      doubt--

 

                DR. GOODMAN:  Now, we are really becoming

 

      lawyers.

 

                DR. NEWMAN:  -- increase the risk of

 

      suicidality, because I really think it is

 

      definitively shown.

 

                DR. GOODMAN:  Ms. Dokken.

 

                MS. DOKKEN:  Yes.

 

                                                               242

 

                DR. GOODMAN:  Dr. Irwin.

 

                DR. IRWIN:  Yes.

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  Yes.

 

                DR. GOODMAN:  Dr. Robinson.

 

                DR. ROBINSON:  Yes.

 

                DR. LESLIE:  Yes.

 

                DR. GOODMAN:  That was Dr. Leslie.

 

                Gail Griffith.

 

                MS. GRIFFITH:  Yes, and I was convinced by

 

      the signal exposed in the TADS data.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Yes.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  Yes.

 

                DR. GOODMAN:  Dr. Goodman, yes.

 

                Dr. Rudorfer.

 

                DR. RUDORFER:  No.  May I take my 30

 

      seconds, please?

 

                DR. GOODMAN:  Yes, please.

 

                DR. RUDORFER:  In my opinion, most of the

 

      trials we reviewed were scientifically flawed. 

 

                                                               243

 

      None were designed to address the question of

 

      suicidality.  What they were designed and powered

 

      to address, namely, efficacy, most failed to do in

 

      the major depressive studies.

 

                I believe that we saw evidence of many

 

      suicidal-related events, however, to assign

 

      causality, I think that was not shown.  I think

 

      that, as we have discussed, to show a

 

      differentiation between active drug and placebo, I

 

      don't believe that the studies were properly

 

      designed to do so, and we have no other

 

      corroboration that the ascertainment of events was

 

      equivalent, and the question of switch into mania

 

      and akathisia, and whether those adverse events and

 

      complications could, in fact, have resulted in or

 

      coded as suicidal events, I think remains a real

 

      possibility, and we simply don't have the data to

 

      disprove that.

 

                DR. GOODMAN:  Jean Bronstein.

 

                MS. BRONSTEIN:  Yes.

 

                DR. GOODMAN:  Dr. Pine.

 

                DR. PINE:  Yes.

 

                                                               244

 

                DR. GOODMAN:  Dr. Gibbons.

 

                DR. GIBBONS:  Yes with a brief statement.

 

      I think the effects are very small.  I think they

 

      are consistent across the studies, but no more so

 

      than the actual data show in the simplest of views.

 

      The rate of these events, Outcome No. 3 is about

 

      double in the drug arms relative to the placebo

 

      arm, and most of the analyses tend to corroborate

 

      that.

 

                Nevertheless, looking across these

 

      studies, looking at the TADS studies, looking at

 

      the naturalistic studies, we see a preponderance of

 

      evidence in favor of rejecting the null hypothesis

 

      of no difference.

 

                I would not be totally surprised, though,

 

      that in further analysis, we might find some

 

      confounding factor, such as initial suicidal

 

      ideation that might be biased across these studies.

 

      Nevertheless, these are randomized studies, and

 

      randomization is a very important tool, hard to

 

      ignore.

 

                Thank you.

 

                                                               245

 

                DR. GOODMAN:  Dr. Ebert.

 

                DR. EBERT:  Yes, with a footnote that we

 

      are looking at the data collectively as a whole.

 

                DR. GOODMAN:  Dr. Grady-Weliky.

 

                DR. GRADY-WELIKY:  I also say yes with a

 

      brief statement that yes to the question as revised

 

      with the appropriate footnotes and definition of

 

      suicidality as suicidal behavior and/or ideation,

 

      and I would agree with Dr. Gibbons' eloquent

 

      comments about the fact that it seems to be a

 

      minimal risk, but something that we should agree

 

      to.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  Yes, and I feel that the data

 

      are really quite compelling given the incredibly

 

      diverse, relatively poor studies, and that we find

 

      a strong signal arising despite the inadequacy of

 

      the studies is very compelling to me.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Nelson.

 

                DR. NELSON:  Yes.

 

                DR. GOODMAN:  Dr. Malone.

 

                                                               246

 

                DR. MALONE:  Yes, although I would like to

 

      add the caveat that I think if you look at some of

 

      the data we saw, that, in general, both drug and

 

      placebo had a decrease in suicidality over the

 

      course of the trials.

 

                DR. GOODMAN:  Dr. Ortiz.

 

                DR. ORTIZ:  Yes.

 

                DR. GOODMAN:  Dr. Fost.

 

                DR. FOST:  Yes.

 

                DR. GOODMAN:  Dr. Pfeffer.

 

                DR. PFEFFER:  Yes.

 

                DR. GOODMAN:  Dr. Fant.

 

                DR. FANT:  Yes.

 

                DR. GOODMAN:  Anuja is going to tally the

 

      votes.

 

                You don't get to vote, Dr. Temple.

 

                DR. TEMPLE:  I don't want to vote, but I

 

      would like to ask a question.

 

                DR. GOODMAN:  Let me give the tally first.

 

                A total of 27 voting.  25 Yes.  1 No.  1

 

      Abstention.

 

                Dr. Temple.

 

                                                               247

 

                DR. TEMPLE:  The committee obviously finds

 

      these data quite convincing.  I was just curious

 

      about Dr. Rudorfer's reservation.

 

                Do I understand that you think there may

 

      have been an ascertainment bias, that certain clues

 

      might make people more inclined to call this in the

 

      treated group than the other group, is that the

 

      nature of it?

 

                DR. RUDORFER:  That is part of it.  In

 

      terms of ascertainment, as I was mentioning at the

 

      end of this morning, there was no systematic way of

 

      collecting these data.  We have no idea what

 

      questions were asked in which study.

 

                It seems to me plausible that a

 

      placebo-treated patient, who was not volunteering,

 

      say, somatic or other complaints, might be

 

      subjected to less interrogation beyond the rating

 

      scales than someone, for instance, who came in

 

      complaining of GI side effects or other SSRI

 

      typical side effects, and I was concerned about the

 

      blind there.

 

                My other larger reservation is that I

 

                                                               248

 

      thought we can't have it both ways.  Either we

 

      think that these drugs are effective or they are

 

      not, and if they are effective, then, we are

 

      looking at a collection of studies which, for the

 

      most part, are showing a lack of efficacy, and I

 

      thought that is not the appropriate context in

 

      which to evaluate the adverse effects, especially

 

      one which we know is integral to the illness under

 

      study.

 

                For instance, if we were looking at, say,

 

      a cardiovascular measure where the illness date

 

      wouldn't necessarily be relevant, I would be less

 

      concerned.

 

                DR. TEMPLE:  The TADS study, of course,

 

      showed both effectiveness and an increase.  That is

 

      just one study, though.

 

                DR. RUDORFER:  I agree with you, on one

 

      hand, yes, it is just one study.  The other is that

 

      TADS is specifically designed as an effectiveness

 

      study, meaning very few exclusion criteria, with

 

      the aim of following upon, but not replacing,

 

      efficacy trials, and I am concerned that we really

 

                                                               249

 

      don't have a collection of good efficacy trials to

 

      evaluate.

 

                DR. GOODMAN:  Because of the overwhelming

 

      affirmative vote to the last question, we don't get

 

      to skip the next one.

 

                Let me turn to Question No. 3 and read

 

      that.

 

                If the answer to the previous question is

 

      yes, to which of these nine drugs does this

 

      increased risk of suicidality apply?  Please

 

      discuss, for example, whether the increased risk

 

      applies to all antidepressants, only certain

 

      classes of antidepressants, or only certain

 

      antidepressants.

 

                Dr. Katz, do you want to clarify?

 

                DR. KATZ:  Yes, I do.  The other grouping,

 

      which we haven't explicitly described in this

 

      question, would be what indications, as well.

 

                DR. GOODMAN:  I was going to add that.  I

 

      agree that I think that the other possibilities

 

      would be the sorted or quarantine indication.

 

                In terms of how to approach this, this is

 

                                                               250

 

      a little bit more data intensive.  In order to come

 

      with an affirmative answer to the last one, you

 

      only had to be convinced that the association was

 

      true for one of the drugs.  Now, we need to I think

 

      have some reference and I wonder again if the

 

      handout from Dr. Dubitsky would be appropriate to

 

      make sure you all have handy as we take a look at

 

      individual compounds and trials.

 

                Again, I think this is going to be a

 

      little bit more labor intensive.

 

                Dr. Nelson.

 

                DR. NELSON:  It would just be helpful for

 

      me to clarify the intent behind No. 3/4, because

 

      one way of answering 3, when you get down to small

 

      numbers in single trials, is to make a pragmatic

 

      decision that you should then apply the grouped

 

      data to individual drugs rather than just a

 

      database decision that, in fact, you have enough

 

      evidence, because I think we are going to take a

 

      big group divided up into many small groups, and

 

      the answer may be no, no, no, no for a number of

 

      drugs where you would still decide that you would

 

                                                               251

 

      want to have a class risk assessment.

 

                So, it would be helpful.  I guess I am

 

      concerned that we don't get to the real question,

 

      which is what to do, if we just spend time on nine

 

      different drugs and three different indications.

 

                DR. GOODMAN:  I think that is a good

 

      point.  I also think there is a statistical

 

      question embedded in it, in that I think it is

 

      easier to answer in the aggregate, because that is

 

      where we still have the stronger significance, but

 

      if I am not mistaken, when you get down to

 

      individual drugs or individual trials, although the

 

      numbers may be higher, the relative risks may be

 

      higher in the drug versus placebo group, it doesn't

 

      reach the levels of statistical significance.

 

                So, I would also like to have some input

 

      from our statisticians on how we should approach

 

      the individual trials or studies.

 

                Dr. Katz first.

 

                DR. KATZ:  I just want to reiterate that

 

      that is exactly what we are asking.  We are asking

 

      about the individual drugs.  We want to know, the

 

                                                               252

 

      numbers are small, the estimates are variable, none

 

      of them really, for the most part, are

 

      statistically significant on their own, but you

 

      have already heard two sponsors with different

 

      drugs.

 

                One said everybody ought to get the same

 

      label. One said the labels ought to be

 

      drug-specific.  So, we anticipated that outcome by

 

      asking the question as we did.

 

                DR. TEMPLE:  We are asking for your best

 

      interpretation of the data.  We already know each

 

      of the drugs is different, each of them can't be

 

      considered statistically significant, but in the

 

      face of that, given the whole data, what do you

 

      think the best interpretation is.

 

                DR. GOODMAN:  I think, generally, when I

 

      hear a class, I am thinking chemical class rather

 

      than particularly how they are used.  There is

 

      certainly a great deal of similarity among the

 

      SSRIs in terms of they all share high affinity for

 

      the serotonin transporter.

 

                When you get to the different

 

                                                               253

 

      antidepressants, there is some variability.  Some

 

      have direct interactions with the serotonin

 

      receptor, some do not, but then some experts in the

 

      mechanism of action of antidepressants might argue

 

      it doesn't matter what their acute receptor binding

 

      profiles look like.

 

                It has to do with what changes they induce

 

      in the nervous system during chronic

 

      administration, and some would argue that a

 

      commonality or changes in serotonin system is

 

      independent of the beginning.

 

                So, I think we could get very much bogged

 

      down on exactly what we mean by chemical class, so

 

      perhaps, I think we are going to have to do it by

 

      individual drug and maybe by indication, but I

 

      would be open to other suggestions.

 

                Dr. Pine.

 

                DR. PINE:  I guess I have a couple

 

      thoughts, two main ones.  Looking at the known

 

      effects on brain neurochemistry of all the

 

      medications that we have before us, one of them is

 

      definitely a bit of an outlier in that Wellbutrin,

 

                                                               254

 

      by most accounts, has clearly different chemical

 

      effects than all the others, and I think that is

 

      the only strong point I would make in that regard,

 

      number one.

 

                Number two, I think a number of people,

 

      both yesterday and today, said the following, which

 

      I would agree with both from the FDA and also on

 

      the committee, that I think a lot of people had a

 

      reasonable sense that fluoxetine was the one

 

      medication for a lot of reasons that, you know,

 

      might not have this effect, and yet we see the data

 

      from the TADS trial that suggests that might be the

 

      case.

 

                So, to the extent that you are really

 

      going to force us to say anything specific about

 

      any medication, at least me personally, my feeling

 

      was that the only feeling that one might have had

 

      coming into the meeting was that the outlier,

 

      besides Wellbutrin, would be fluoxetine, and I

 

      think at least with respect to fluoxetine, the data

 

      from the TADS trial, you know, takes that away at

 

      least from my opinion.

 

                                                               255

 

                DR. GOODMAN:  Well, maybe this raises also

 

      a question.  We said that we were going to focus on

 

      the clinical trials.  Does that mean we should not

 

      include the data from the TADS study?  That's the

 

      Plus 1.  You were right, Tana, we should have been

 

      very explicit.  That's the Plus 1.  I was

 

      forgetting that that was the Plus 1.

 

                Dr. Fant.

 

                DR. FANT:  You spoke to the question in

 

      terms of defining what do we mean by class and how

 

      to address the drug issues, because, you know, one

 

      looks at Wellbutrin, but if it was an SSRI, I might

 

      be inclined to be biased in a direction of safety

 

      to sort of lump it in with the others, and look at

 

      it as a class effect, but I am not sure if I am

 

      willing to sort of roll that in without any input

 

      from anyone else to tell me that that's off base

 

      with the effects that we are seeing with Effexor.

 

                DR. POLLOCK:  Right, exactly, and going

 

      the other way, Remeron is clearly not an SSRI also,

 

      and we have data on that.

 

                DR. GOODMAN:  You have to wait until you

 

                                                               256

 

      get called, because I have got other people waiting

 

      here.

 

                DR. POLLOCK:  I am sorry.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  I think we, in approaching

 

      this question, need to be clear.  Are we answering

 

      this question as an interpretation of data issue

 

      where you could simply take out the slides that

 

      were provided and look at confidence intervals,

 

      much as what we did as opposed to do we think

 

      regardless of the data, we should apply a class

 

      label for warning against suicidality, however that

 

      is defined, which is really Question 4.

 

                In answering this question, I think we

 

      just need to be clear that it is an interpretation

 

      of data.  Even if I said that the data doesn't

 

      support it for one drug, I may still support a

 

      class warning.  In the interests of efficiency, I

 

      think we just need to run to get to the real

 

      question, which is what to then do.

 

                DR. FANT:  Again, how are you defining

 

      class, are you defining class as "antidepressant"

 

                                                               257

 

      or chemical class?

 

                DR. NELSON:  All of the drugs we have been

 

      talking about.  I mean I am not a psychiatrist, so

 

      all of the SSRIs.

 

                DR. FANT:  The reason I asked that is

 

      because, like the Chair, I mean when I think of

 

      class, I think of class based on mechanism of

 

      action as opposed to therapeutic.

 

                DR. NELSON:  Correct.  Simplistically, I

 

      think of class when I go into Hippocrates or My

 

      Palm, and it says SSRIs and has a name next to it.

 

      That is how I think of class.

 

                DR. GOODMAN:  But there is overlap.  The

 

      point I was trying to make is that there is some

 

      overlap.

 

                Certainly, there are some differences and

 

      that the SNRIs, like venlafaxine, also have potent

 

      effects on the norepinephrine system, but they

 

      share, they overlap, at least at some dosages, have

 

      high affinity for the serotonin receptor, or we

 

      don't understand exactly how bupropion works.

 

                What I was alluding to also is their acute

 

                                                               258

 

      properties may not be as relevant as what their

 

      impact is on the adaptation of the nervous system

 

      during chronic administration, so there may be some

 

      independence between the initial effects and the

 

      ultimate final pathway of the effect, because

 

      obviously, the nervous system is functionally

 

      coupled.  These are not distinct systems for the

 

      most part.

 

                Dr. Marangell.

 

                DR. MARANGELL:  I think all those comments

 

      are quite valid.  I imagine that many people group

 

      SSRIs together and will probably want a class

 

      statement of SSRI Yes/No, antidepressants Yes/No,

 

      and then whether or not you want to break out SNRIs

 

      and Remeron and Wellbutrin as others.

 

                DR. GOODMAN:  I would be comfortable with

 

      that approach.

 

                Dr. Perrin.

 

                DR. PERRIN:  I would encourage that

 

      approach.  It seems to me, looking at the data,

 

      that the ones that raise questions to us--to me, I

 

      am sorry--are Wellbutrin and the nefazodone data

 

                                                               259

 

      where there are basically no events.

 

                You might argue that these are really

 

      different drugs in that context, but my sense is

 

      the Wellbutrin one, probably simply because this is

 

      only kids with ADHD, and there are no kids with

 

      depression in that population, at least to the

 

      degree we can define it, we can't define it very

 

      well.  There certainly could have been some kids

 

      with co-existing depression.

 

                The nefazodone, I would like to have us

 

      understand more about it.  That is why I have asked

 

      about it, but my guess is it is also a

 

      population-based finding that has nothing to do

 

      with the drug, because there were no events in the

 

      placebo group either.

 

                DR. GOODMAN:  Dr. Gibbons.

 

                DR. GIBBONS:  I think that really this

 

      ends up being a statistical issue.  Dr. Hammad has

 

      shown very clearly that these studies, even

 

      combined within drug classes, are insufficient to

 

      have reasonable power of rejecting the null

 

      hypothesis for even a fairly major effect.  You

 

                                                               260

 

      know, we are out at about a risk ratio of about 4

 

      to have reasonable power, and so I really don't

 

      think that we have the data to be able to make

 

      drug-specific statements, period.

 

                Now, if the committee wants to make

 

      statements that there is clear heterogeneity among

 

      the effects across drugs, and even point to those

 

      drugs that show less of a signal than others, that

 

      seems totally reasonable to do, but to use these

 

      limited data for a particular drug to make an

 

      informed decision about whether or not this already

 

      small signal has anything to do with one drug, but

 

      not another drug, I think is reaching beyond the

 

      available data.

 

                DR. GOODMAN:  Dr. Malone.

 

                DR. MALONE:  Yes, I agree that we have to

 

      look at all the drugs, and I think if you look at,

 

      say, the difference between the TADS study and the

 

      other studies, I think the other studies were not

 

      set up to look at suicidality very specifically,

 

      but my impression was that the TADS study did look

 

      at it more systematically.

 

                                                               261

 

                When it was looked at more systematically,

 

      you came up with a finding in fluoxetine that you

 

      didn't have in the less systematic studies.  So,

 

      missing a signal or having a lower signal might

 

      really just be ascertainment, and I think for that

 

      reason, you have to look at it as a class.

 

                DR. GOODMAN:  Could somebody remind me, in

 

      the analysis of SSRIs alone in major depression,

 

      did that reach the level of statistical

 

      significance for showing elevated risk level?

 

                Could you please come to the microphone,

 

      Dr. Hammad.

 

                DR. HAMMAD:  Yes, it did.  I can get you

 

      the actual number.  Yes, the overall risk for

 

      SSRI/MDD, it was 1.66, and the confidence interval

 

      was 1.02, the lower limit, and the upper limit is

 

      2.68.

 

                DR. GOODMAN:  So, that included

 

      fluoxetine, paroxetine, sertraline.  What am I

 

      missing?  It wouldn't be venlafaxine, it's SSRI,

 

      right?  Citalopram, I am sorry, citalopram.

 

                Let me go back to Dr. Gibbons for a

 

                                                               262

 

      moment.  Given that, assuming we were just voting,

 

      not voting, but we were just commenting on a class

 

      of SSRIs in major depression, would you be

 

      comfortable drawing a conclusion based upon the

 

      data we have?

 

                DR. GIBBONS:  I think you can make the

 

      statement within this class, you have reached

 

      statistical significance, but I don't think you

 

      have the data to make the statement that among the

 

      other drugs you don't have statistical

 

      significance.  So, that's the rub.

 

                Again, I think in all of this, you have to

 

      explain as clearly as possible what are the

 

      limitations of the data, so that you are not

 

      misinterpreted as saying there isn't an effect or

 

      there is an effect.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  I was taught 20 years ago

 

      when we were in the tricyclic era that when you

 

      initiate treatment of depression, there is an

 

      increased risk of suicidality, and I think since

 

      the SSRIs don't cause cardiac arrest when you

 

                                                               263

 

      overdose, everybody forgot that need, and that is

 

      one big problem.

 

                As many other people have said, I think we

 

      don't have the data based on these small, miserable

 

      studies to say that they are safe.

 

                The last thing that I thought of, we had a

 

      strong argument yesterday for differential

 

      labeling, and I think companies go to great lengths

 

      once things are marketed to show an advantage of

 

      their drug over their competitors, and there are

 

      always pretty much sham studies that are set up, so

 

      drug reps go around that can say one is better than

 

      the other.

 

                I don't want to let the wolf into the

 

      henhouse by letting any company say that since my

 

      drug hasn't been shown to cause suicidality, there

 

      is an advantage to it compared to that other drug

 

      over there.  I think that would be a terrible,

 

      terrible mistake.

 

                DR. GOODMAN:  Dr. Fost.

 

                DR. FOST:  Just a point of order.  I am

 

      not clear whether we are discussing Question 3 or

 

                                                               264

 

      Question 4, and I want to second Skip Nelson's

 

      suggestion that we focus on Question 4, because if

 

      there is agreement on that, then, I don't think

 

      there would be much value in going through it drug

 

      by drug, condition by condition, unless somebody

 

      wants to subtract--

 

                DR. GOODMAN:  You may be right.  Let's all

 

      take a moment to look at that.

 

                I think the heart of the next question is

 

      what recommendations we are making.  Isn't that

 

      really the thrust of No. 4, is the regulatory

 

      recommendations.

 

                DR. KATZ:  Yes, I think including, more or

 

      less, some specific recommendation.  We don't need

 

      exact language, but, in general, what concepts

 

      ought to be conveyed in labeling, and then, of

 

      course, any additional regulatory actions besides

 

      just changing labeling are on the table.

 

                DR. GOODMAN:  I still think we need to

 

      answer Question No. 3.

 

                DR. TEMPLE:  I think you are having the

 

      right discussion about 3.  Three is asking you, in

 

                                                               265

 

      the face of limited data, what is the best

 

      interpretation of these results.  We already know

 

      you don't have enough data on Effexor or any

 

      individual drug, we knew that, and if that was the

 

      question, we wouldn't have asked you.

 

                The question is in the face of these

 

      limitations, what is the best interpretation, and I

 

      think you are having a good discussion of that

 

      question.

 

                DR. KATZ:  But for our purposes, it is

 

      useful if you are going to say something like,

 

      well, we believe the findings generalize to all the

 

      drugs, it would be useful to have some comment on,

 

      for example, some of the drugs that have no events.

 

      It would be useful to consider why you think those

 

      should be included, as well.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  I guess as a summary

 

      position, I certainly don't see any reason to

 

      question the data that has been put before us, and

 

      I would probably just follow the confidence

 

      intervals as a fair neophyte.

 

                                                               266

 

                So, I have to defer those to my

 

      psychiatric colleagues about the other drugs

 

      without events and how those may or may not be

 

      included.  That is really an issue that I wouldn't

 

      be able to address, but I think if we are going to

 

      just follow the confidence intervals, like most of

 

      us did last time, we should just sort of say that

 

      and then move on.

 

                DR. GOODMAN:  Could I ask Dr. Hammad or

 

      Dr. Laughren, which of the medications were free of

 

      a signal, just remind us?

 

                DR. LAUGHREN:  Do you have my slides from

 

      this morning?  Slide 8 shows that there were no

 

      events in the Serzone, the two Serzone trials.

 

      These were trials in major depression.  There were

 

      no events in the Wellbutrin, the one Wellbutrin

 

      trial, which was an ADHD trial.

 

                DR. GOODMAN:  Dr. Gorman.

 

                DR. GORMAN:  As one of the least

 

      sophisticated statisticians around the table, I

 

      harken back, as someone else did, to their early

 

      training.  I once asked a statistician what to do

 

                                                               267

 

      with a zero numerator, and they said whenever you

 

      see a zero numerator, you can always write a 3 in

 

      there, because mathematically, it works out that

 

      way.  Don't ask me for the mathematical proof, I am

 

      sure someone here can do it for me.

 

                So, even in the small trials, when there

 

      is a zero numerator, I think we can do some

 

      interpretations.  I will bring the reference for

 

      the next committee meeting.

 

                DR. GOODMAN:  There are special

 

      circumstances surrounding the Serzone trial that

 

      could explain it besides the drug itself.  Are

 

      there any that could explain that outcome?

 

                Dr. Malone.

 

                DR. MALONE:  I think we have already

 

      talked about these studies not being designed to

 

      look at suicide, so ascertainment could have been

 

      different in that study than any other study, and

 

      lack of ascertainment could be the reason they have

 

      no events.  It is really hard to know.

 

                DR. GOODMAN:  And the Wellbutrin study was

 

      in ADD, wasn't it?

 

                                                               268

 

                DR. MALONE:  Yes, and I don't think in

 

      ADHD, I am a child psychiatrist, I am not sure that

 

      suicidality becomes a clinical focus, so in the

 

      visits, it may not have been asked about as much,

 

      or even paid attention to as much.  I am not

 

      surprised that in the Wellbutrin you didn't have

 

      any events.

 

                DR. GOODMAN:  Dr. O'Fallon.

 

                DR. O'FALLON:  I looked in the back of

 

      this book. We didn't see all those follow-up

 

      slides, but I looked at them last night, and they

 

      are rather useful.  On page 35, the diagram, for

 

      SSRIs, as a class in the MDD trials, and those are

 

      the four, and you take a look in here, and it comes

 

      up with the right confidence interval down at the

 

      bottom.

 

                But you can take a look and see that the

 

      confidence interval for the whole class just barely

 

      clears 1, so we are looking at a 0.05 level here.

 

      Actually, the verification using the other modeling

 

      doesn't quite even--it kind of takes away from that

 

      a little bit.

 

                                                               269

 

                DR. GIBBONS:  I believe the random effect

 

      in this case a little more than the fixed effects.

 

                DR. O'FALLON:  So, that puts the 0.05 up a

 

      bit, like 0.052, or something like that, but at any

 

      rate, you can take a look at that.  It does show

 

      you where your signal is in the SSRI trials in MDD.

 

                If you look on the next page, at the top,

 

      there is a similar diagram for I believe it's the

 

      SSRIs in the other indications, and you can see the

 

      signal there.  That signal fails to be significant

 

      in suicide, and that is on the key endpoint that

 

      you were talking about, 1, 2, and 6 as the

 

      endpoint.  Does that help?

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  A couple of points in

 

      response to recent comments.  One is what is

 

      different about Serzone. Perhaps it's not the

 

      methodology.  I mean you could hypothesize that

 

      mechanistically, Serzone has a 5HT2 antagonist

 

      which has been at least theoretically associated

 

      with a decreased early agitation and early anxiety

 

      realm of side effects, but pragmatically speaking,

 

                                                               270

 

      the manufacturer has stopped producing that drug

 

      because of other issues.

 

                So, in terms of the use of our time, it

 

      might be of academic interest, but I am not sure it

 

      is going to make a clinical difference to the

 

      people that we are trying to help.

 

                The other point is that one of the things

 

      I think the TADS trial very clearly indicates is if

 

      we had the same discussion prior to that single,

 

      relatively small, but very helpful study, we would

 

      have said fluoxetine looks like it doesn't have a

 

      signal.

 

                So, the point is that one very small group

 

      of patients can dramatically alter these numbers

 

      that we are talking about.  So, I think to finally

 

      dissect them at the level of whether there is or is

 

      not a statistically significant signal with these

 

      very small numbers is likely to lead us in the

 

      wrong direction.

 

                The public and the FDA want something

 

      about SSRIs versus all antidepressants, if you just

 

      look at statistical significance of that, you could

 

                                                               271

 

      probably pick any four of these drugs at random and

 

      come up with something similar, I mean since you

 

      have drugs that have a signal and don't within that

 

      same class.

 

                DR. GOODMAN:  As it has been discussed, in

 

      fact, this led to at least one of the abstentions,

 

      and also some of the other comments, is that even

 

      in aggregate, there are limitations in these data.

 

      When you break it down to the individual drug, the

 

      numbers get vanishingly small.

 

                It would seem to me, my sense at this

 

      point, it would be premature to identify a

 

      particular drug that should be exempted from this

 

      warning, the reason being, in part, that if we were

 

      to exempt one, it would conceivably have the

 

      unintended consequence of steering traffic in that

 

      direction prior to us having sufficient knowledge

 

      about the true risk, and we may inadvertently then

 

      learn that there was a risk there at our next

 

      meeting.

 

                So, I think given the statistical

 

      concerns, the small numbers, and my own clinical

 

                                                               272

 

      impressions, that for the most part, when I have

 

      seen at least--thank God I haven't seen

 

      suicide--but I have seen suicidal behavior,

 

      suicidal ideation, I have seen the activation

 

      syndrome, for the most part, I have seen it with

 

      most, I am not saying all, but with most of the

 

      antidepressants, and I have not seen it limited to

 

      major depression.

 

                I have seen it in the treatment of

 

      children with OCD, and there is, in fact, evidence

 

      of that in these trials, that it occurred in the

 

      OCD patients, as well, with fluvoxamine, although

 

      the numbers were very small.

 

                So, unless I think there is a very good

 

      reason for us to do it, I think we are best off

 

      talking about the class, not on a chemical basis,

 

      but as antidepressants used in the pediatric

 

      population.

 

                But you can take shots at that position

 

      now, but that is where I am leaning.

 

                Dr. Pfeffer.

 

                DR. PFEFFER:  I would agree with that, and

 

                                                               273

 

      I would just like to highlight again, on the blue

 

      pages that we have, two issues that I would like to

 

      highlight.

 

                First, many of the studies did not exclude

 

      a family history of bipolar disorder, and I think

 

      that is an important design issue that we need to

 

      keep in mind in even considering comparing, first

 

      of all.  In relation to Serzone, to be specific,

 

      interestingly, they did exclude a family history,

 

      but they also excluded history of a suicide

 

      attempt.

 

                So, there may be other issues besides the

 

      chemistry, as you are saying, but could be

 

      confounding this. When you put everything together

 

      as a class, I think that is an interesting and

 

      important issue, because it may say to practicing

 

      clinicians, be wary of the SSRIs in general, but

 

      there may be specific populations, then, that they

 

      need to identify, for example, family history.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  Also, even mechanistically,

 

      mirtazapine also has a 5HT2 blocking effect, and it

 

                                                               274

 

      is clearly in our group, and I am concerned about

 

      the sloppiness of saying SSRIs, because

 

      practitioners will say, you know, in a telegraphic

 

      fashion, that, well, does that mean since I know

 

      that mirtazapine and Effexor are not SSRIs, that

 

      that might be safer.

 

                So, I just second your idea that if we are

 

      going to do it, then, I think on the basis of the

 

      available evidence, I would rather not see it as,

 

      quotes "SSRIs," unless you are entirely explicit

 

      about the other couple of drugs, or if you just say

 

      antidepressants, my preference is for the class in

 

      that terms rather than trying to make it

 

      mechanistic.

 

                DR. GOODMAN:  Dr. Ortiz.

 

                DR. ORTIZ:  My comment is that I also

 

      agree that I think we don't have enough information

 

      to say that particularly the bupropion is safe and

 

      that we should stick to antidepressants.  I am

 

      wondering if we are not moving into kind of

 

      research design recommendations, and if we

 

      shouldn't at this point.  It seems like we have

 

                                                               275

 

      talked enough about 3 and 4 to vote on them.

 

                DR. GOODMAN:  Just procedurally, I am not

 

      sure we need to take a vote on this.  We haven't

 

      been asked to take a vote on it, but I am open to

 

      discussion.

 

                Dr. Katz.

 

                DR. KATZ:  I think it would be useful to

 

      have a vote.  I mean the sentiment, at least the

 

      few people who have expressed one explicitly, seems

 

      to be that this signal should be considered to

 

      apply to all of the drugs, for all of the

 

      indications.

 

                But  I think it would be very useful for

 

      us to actually get a vote on that particular

 

      proposal.

 

                DR. GOODMAN:  Would you like to pose the

 

      question, Dr. Katz?

 

                DR. KATZ:  Well, I think I sort of did.

 

                DR. GOODMAN:  We need to hear it again.

 

      See if you can do it again.

 

                DR. KATZ:  I will see if I can do it under

 

      pressure now.

 

                                                               276

 

                DR. GOODMAN:  We will give you a few

 

      minutes.

 

                DR. KATZ:  Should the signal of increased

 

      risk apply to all drugs studied or all

 

      antidepressants including all indications studied,

 

      words to that effect.

 

                DR. TEMPLE:  You actually proposed it.  I

 

      don't remember your exact words, but probably

 

      someone does.  I think you said something like the

 

      best interpretation of these data is that it should

 

      be applied to all drugs used for pediatric

 

      depression and other conditions.

 

                DR. GOODMAN:  All antidepressants.

 

                DR. TEMPLE:  All antidepressants when used

 

      for all of these conditions, not that we know that

 

      to be true obviously.

 

                DR. GOODMAN:  Psychiatric conditions.  We

 

      have heard I think some examples from the open

 

      public forum where it was used for non-psychiatric.

 

      It may be when used in the pediatric population for

 

      all indications, and, of course, there are very few

 

      indications.

 

                                                               277

 

                DR. TEMPLE:  All the studies were for

 

      indications pretty much that the drugs have.

 

                DR. GOODMAN:  Okay.  So, we will limit it

 

      to the indications that are under study, all the

 

      indications, psychiatric indications.

 

                Would somebody put that question together

 

      for me?

 

                In the meantime, Dr. Marangell, as we try

 

      to draft it.

 

                DR. MARANGELL:  I was going to try and

 

      draft it for you.

 

                DR. GOODMAN:  Please.

 

                DR. MARANGELL:  I move that we vote that

 

      the committee's opinion is that the increased

 

      suicidality, as previously defined, pertains to the

 

      use of the nine antidepressants listed for all

 

      indications studied to date.

 

                DR. GOODMAN:  I like that.

 

                DR. McGOUGH:  Can I ask a question?  I

 

      don't want to lose sight of other drugs approved

 

      for depression.  There are tricyclic

 

      antidepressants, there are MAOIs, and I think part

 

                                                               278

 

      of the decision is do we include all those, as

 

      well, and is this a general recommendation for any

 

      drug that is indicated for depression.

 

                DR. PINE:  Can I make a comment, too,

 

      about both of those comments?

 

                DR. GOODMAN:  Dr. Pine, go ahead.

 

                DR. PINE:  I would feel more comfortable,

 

      and again maybe nobody agrees with this, but I

 

      would be interested in your thoughts, if you made

 

      the statement more of a negative, since I think it

 

      more accurately reflects the data.

 

                In other words, none of the agents should

 

      be excluded from this warning, because I feel more

 

      comfortable and can confidently make that

 

      statement, whereas, when you make the statement

 

      that it applies to all, you know, particularly

 

      agents where there is no event, I am kind of left--

 

                DR. GOODMAN:  I think that is the

 

      corollary, but I think it would be hard to

 

      translate the corollary into practice.

 

                DR. PINE:  The first statement was

 

      something about a warning that we just voted on

 

                                                               279

 

      already, Question No. 2, and then the second one

 

      was no agent should be excluded from this warning--

 

                DR. GOODMAN:  Let me return to Dr.

 

      McGough's comment for a moment in terms of whether

 

      we should be expanding our considerations to

 

      tricyclics and MAOIs.  I don't think we can because

 

      if we look at the history of this process today, we

 

      are focusing on the clinical trials, although I

 

      would agree with you that based upon clinical

 

      experience, one would suspect similar kinds of

 

      problems with tricyclics.

 

                In fact, we saw that in one of the studies

 

      based upon the British sample showed no significant

 

      difference in relative risk between dothiepin,

 

      which is a tricyclic.

 

                DR. McGOUGH:  I think there are actually

 

      other reasons in addition not to use those other

 

      classes, and I don't even think they are used very

 

      commonly.

 

                DR. GOODMAN:  Because of cardiovascular

 

      concerns, yes.  I hear your point from a clinical

 

      standpoint, but I think based upon the data under

 

                                                               280

 

      consideration, I would agree with Dr. Marangell's

 

      rendering of the question.

 

                Other comments?  Dr. Newman.

 

                DR. NEWMAN:  I like the phrasing except

 

      that I wouldn't restrict it to when the drugs are

 

      used for the indications for which they were

 

      studied, because we heard of one girl who got one

 

      of these drugs for migraines, and I would just say

 

      when given to pediatric patients, and not restrict

 

      it to the indication studies, because, you know,

 

      also, people are getting it for sleep.

 

                So, I would just make it very broad, when

 

      given to children, they can increase suicidality.

 

                DR. GOODMAN:  I have to agree with that.

 

                Dr. Gorman.

 

                DR. GORMAN:  Agree.

 

                DR. GOODMAN:  Dr. Gorman, you agree also?

 

                DR. GORMAN:  Agree.

 

                DR. GOODMAN:  Tom.

 

                DR. LAUGHREN:  Just a thought.  Clearly,

 

      when you are moving from Questions 1 through 2

 

      through 3, going from 1 to 2, clearly the focus is

 

                                                               281

 

      on the 24 trials that we looked at.  I think as you

 

      move towards 3 and 4, I personally don't see any

 

      problem.

 

                I mean if you have reached a conclusion

 

      that you can expand this claim to the

 

      antidepressant class, in other words, you are

 

      willing to ignore findings of no events for certain

 

      trials, I don't think it is so unreasonable to

 

      consider expanding it to the whole class, and here

 

      is my reasoning for that.

 

                I think there is a great risk in steering

 

      clinicians back to using the tricyclics as an

 

      alternative to a safe group of drugs, which all of

 

      us know are not, so it is just something to think

 

      about.

 

                DR. GOODMAN:  Dr. Marangell, could you

 

      restate that question now including all

 

      antidepressants in the pediatric population, could

 

      you try it?

 

                DR. MARANGELL:  I can try.  I move that

 

      the committee adopt the position that

 

      antidepressant agents, when given to pediatric

 

                                                               282

 

      patients, defined 7 to 17 years old, increases the

 

      risk of suicidality as previously--no?

 

                DR. GOODMAN:  Let her finish and we will

 

      get back to the age range.

 

                DR. MARANGELL:  I move that the committee

 

      consensus is that the risk of suicidality, as

 

      previously defined, applies to all antidepressants

 

      when used in pediatric patients.

 

                DR. GOODMAN:  I like that.  Was there a

 

      desire to not qualify what we mean by pediatric, or

 

      to qualify differently?

 

                Dr. Leslie.

 

                DR. LESLIE:  I just feel that 7 to 17 is

 

      not a good direction to go in.

 

                DR. GOODMAN:  So, it is sufficient to say

 

      pediatric?

 

                DR. LESLIE:  And I just wanted to add the

 

      other reason I would say that this is important to

 

      say broadly is we have got Cimbalta and other

 

      things coming out, and you don't want someone

 

      saying, well, Cimbalta doesn't have this warning,

 

      so you ought to use it instead of Luvox, et cetera.

 

                                                               283

 

                DR. GOODMAN:  Did anybody transcribe that?

 

      I am comfortable with the statement.  They are on

 

      it.  We are about to project it.

 

                Dr. Katz.

 

                DR. KATZ:  I would just like to hear a

 

      little bit more discussion about applying the

 

      warning, whatever it is that we apply, at least

 

      applying the result to non-psychiatric indications.

 

                We don't have any trial data in that

 

      population. We have reports of individual cases,

 

      and clearly they are used for other things, but I

 

      would just like a little more discussion or hear

 

      what people think about extending it to all

 

      possible indications for which these drugs might be

 

      used.

 

                DR. GOODMAN:  Once Tom gave us some

 

      freedom to not confine ourselves to the clinical

 

      trials, I think led us to consideration of all

 

      antidepressants and all possible indications, but,

 

      sure.

 

                Dr. Nelson.

 

                DR. NELSON:  In looking, for example, at

 

                                                               284

 

      the current labeling, I think the restriction to

 

      major depressive disorder is potentially falsely

 

      reassuring, and it would concern me if it was

 

      listed only for psychiatric conditions, that the

 

      same thing would happen with the off-label use in

 

      non-psychiatric conditions.

 

                Even though there is no data suggesting

 

      that, by having a warning associated with the drug,

 

      and not with the condition, the way a clinician

 

      could possibly read this would be here, I am giving

 

      you this drug, but since you are not depressed, it

 

      is not going to happen in you, so therefore, it is

 

      safe, and we can't say that.

 

                That is the way it would be read, so I

 

      think by not listing it to the drug, you open up

 

      that possible interpretation to a clinician, which,

 

      in the absence of evidence, I think would be a

 

      danger.

 

                DR. GOODMAN:  I agree completely, and I

 

      think, although we haven't discussed this at great

 

      length, and I don't know how many people would

 

      agree with this statement, but I think at least I

 

                                                               285

 

      do, and I have heard some other mention the fact

 

      that our hypothesis of the mechanism here is some

 

      sort of behavior toxicity that may be compounded by

 

      an interaction with an underlying proclivity, such

 

      as bipolar diathesis.

 

                It may have to do something about

 

      metabolism or drug levels.  There are a number of

 

      other factors that can contribute, but once I saw

 

      the data in the OCD trials, although it is only a

 

      few cases, I began to think, and also based on my

 

      own experience, that this isn't strictly worsening

 

      of depression or ineffectiveness in treating

 

      depression, especially since in a number of the

 

      cases, it seems to happen so early in the course.

 

                So, I would agree completely that I think,

 

      in part, our recommendations reflect a working

 

      hypothesis that what we are seeing, although a rare

 

      event, may represent behavioral toxicity that can

 

      occur in individuals other than those already

 

      diagnosed with depression.

 

                We have the revised question up on the

 

      screen--no, we don't.

 

                                                               286

 

                DR. TEMPLE:  That is my revision, it is

 

      not exactly the same as others, and you don't have

 

      to take it.

 

                DR. GOODMAN:  We are going to have to

 

      change it.

 

                Dr. Marangell, what do you think?

 

                DR. MARANGELL:  If you say the best

 

      interpretation of the results of the 23 plus 1,

 

      then, it would be the indication studied.  If you

 

      say what is our, you know, kind of interpretation

 

      of where we go with those results, then, it is a

 

      little bit broader.

 

                DR. GOODMAN:  I would like to go with

 

      broader.  I don't know if we can change it on

 

      there.

 

                Other comments?  Dr. Chesney.

 

                DR. CHESNEY:  When you introduced applying

 

      this principle to all antidepressants, this is a

 

      whole new ballpark for me, because I don't know

 

      anything about them, and we don't have any data,

 

      and maybe I misunderstood, but if I didn't

 

      misunderstand, could somebody explain to me why we

 

                                                               287

 

      should extend whatever we decide about what we have

 

      heard about, to things that we have heard nothing

 

      about?

 

                DR. GOODMAN:  What is it that we haven't

 

      heard about?

 

                DR. CHESNEY:  All the other

 

      antidepressants.  What I heard was that we extend

 

      this, not just to SSRIs, that we know about, but to

 

      all other antidepressants, and I don't know

 

      anything about them.

 

                DR. GOODMAN:  We have covered most of the

 

      field, but I would let others--

 

                DR. MARANGELL:  There are two areas of

 

      extension in regard to the revised Question 3.

 

      What I was actually just referring to was the

 

      extension to pediatric use or any use in pediatric

 

      patients as opposed to just the uses that were

 

      studied, and the rationale for that portion is, you

 

      know, clearly it is beyond major depression for

 

      those of us that think that there is a consistent

 

      signal, you see that also in some of the non-major

 

      depression indications, such as the OCD trials.

 

                                                               288

 

                So, that is the reason to extend that, and

 

      then the feedback we got, that I heard from the

 

      rest of the committee was that even beyond those

 

      trials, there may be other indications, and we

 

      don't want to try and give the signal that it is

 

      limited to, you know, if a doc wants to use an

 

      agent for a pain condition, that we wouldn't expect

 

      to see it there.

 

                In terms of other antidepressants, the

 

      tricyclics and the MAOIs are older agents, and my

 

      understanding is that they have never been studied

 

      in pediatric patients, so we have no data, is that

 

      correct?

 

                DR. TEMPLE:  It is not a bad idea to take

 

      those questions in sequence.  First, think about

 

      the drugs that were studied and what is the best

 

      interpretation of them, and then, you know, we

 

      might approve a new antidepressant, and is it going

 

      to be the only one that doesn't bear that label?

 

      Do you like that idea?  We will get to that.

 

                DR. LAUGHREN:  Actually, a clarification.

 

      Some of the older drugs have, in fact, been

 

                                                               289

 

      studied, but FDA has not seen the data, they have

 

      never been submitted.  There are at least 12 trials

 

      in tricyclic antidepressants in pediatric

 

      depression that I am aware of, but I don't know how

 

      well those patients were ascertained or

 

      suicidality, I know nothing about the safety in

 

      those trials.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Again, I think when you

 

      treat depression, there is an increased risk of

 

      suicide.  Most of this is off-label, so to restrict

 

      it to indications is kind of an illogical event,

 

      that somebody would get Zoloft for insomnia is

 

      beyond anything I can understand.

 

                So, I think really the purpose of this, I

 

      think is to really put physicians on notice that

 

      this group of medicines can cause these problems

 

      for whatever they think of.  To be safe, I think we

 

      are really putting the physicians, you know, the

 

      real attempt is to inform them that they need to be

 

      concerned, they need to monitor for whatever they

 

      are using this for.

 

                                                               290

 

                DR. GOODMAN:  Dr. Robinson.

 

                DR. ROBINSON:  One of the things that I

 

      took away from a lot of the public testimony

 

      yesterday was how much the people said they wanted

 

      to have known things before they got into a

 

      treatment.

 

                I think one of the things that we have to

 

      deal with is that we do not know a lot about some

 

      of the other drugs, like the tricyclics, the MAOIs,

 

      we just don't have the information because they

 

      were done so long ago.

 

                Now, I personally think that it would be a

 

      great tragedy if clinicians went from using SSRIs

 

      to tricyclics, which have a much lower overdose.

 

      You can kill yourself taking much, much fewer

 

      pills.

 

                But I think we also have to be humble

 

      enough to say, you know, there are certain things

 

      we don't know.  We don't know about the risks for

 

      tricyclics, we don't know about the risks of SSRIs

 

      used for these off-label non-psychiatric

 

      indications.  We just don't know, and there is no

 

                                                               291

 

      information.

 

                In some ways, that is the most accurate

 

      thing to tell a prospective family thinking about

 

      these drugs, is we know for certain indications, it

 

      has an increased risk of suicide.  For this stuff,

 

      we don't know, it might be a lot worse, it might be

 

      better, we just don't know, but take this into

 

      consideration.

 

                DR. GOODMAN:  Before I get to you, Dr.

 

      Temple, I actually don't think it is such a bad

 

      question.  I think that by answering this question,

 

      it allows us to put Question 3 behind us, and then

 

      I think a lot of the discussion that we are having

 

      is then what should we recommend in terms of

 

      further regulatory action, and I think that is

 

      really getting it to Question 4.

 

                Would that be a reasonable way of sorting

 

      out where we are right now, to try to maybe answer

 

      the one that is up there, and then we can talk

 

      about whether, in our recommendations in terms of

 

      further warnings, that maybe that issue should be

 

      expanded further, but this would be a good

 

                                                               292

 

      transitional question, as I see it.

 

                Dr. Temple.

 

                DR. TEMPLE:  There really are two parts.

 

      The first part in some ways is I think what most

 

      people have given their answer to that.  The second

 

      part I just was writing quickly referred to

 

      tricyclics, but it is worth thinking a little bit

 

      here about whether the best interpretation is that

 

      it applies to some study, some new drug like we

 

      just approved one that hasn't been tested yet.

 

                We are going to surely have to come to

 

      grips with that question, too, so it says

 

      tricyclics, it could have said MAO inhibitors, it

 

      could have said duloxetine.

 

                That is the second question, but I think

 

      that follows the first.

 

                DR. GOODMAN:  I would like to take off

 

      after the second bullet for a moment.  Unless there

 

      is further discussion, I would actually like to

 

      vote on that question that is up there.

 

                Dr. O'Fallon.

 

                DR. O'FALLON:  Again, on page 34 of the

 

                                                               293

 

      thing we got yesterday, there is a nice diagram

 

      that shows the relative risks and their confidence

 

      intervals for all of the nine drugs, all of the

 

      indications, and what you will see, when you look

 

      at it, is that every drug has at least one trial

 

      that shows an increased drug.

 

                You can make the argument that there is

 

      some evidence for every single one of these.

 

                DR. POLLOCK:  If we are saying the nine

 

      drugs, it includes Wellbutrin, which isn't one of

 

      these.

 

                DR. O'FALLON:  Perhaps, but what I wanted

 

      to point is that every single one of these drugs

 

      has at least one, some more, that show an

 

      increased--okay, eight, whatever--it says all

 

      drugs.

 

                DR. GOODMAN:  Unless there is further

 

      discussion, I would like to put this to a vote.

 

      The reason, why do I want to answer this, because

 

      it is our job to try to answer the questions that

 

      were presented before us.

 

                I think that if we don't answer this, it

 

                                                               294

 

      is not clear from our last vote whether we were

 

      thinking of just one drug or many drugs.  So, this

 

      is the natural sequence that we are making it clear

 

      by this that we are talking about in aggregate when

 

      we look at the data.  We are not exempting any of

 

      the drugs for any of these pediatric indications.

 

                So, I think we need to answer this

 

      question, and it should be put to a vote.

 

                Yes.

 

                DR. FANT:  Just another way of phrasing

 

      that which may be more palatable.  If things are

 

      just transposed a bit, to say is the best

 

      interpretation of the results of the 23 plus 1

 

      trials, that none of the drugs examined can be

 

      excluded from the increased suicidality risks that

 

      has been shown da-da-da.

 

                DR. GOODMAN:  Let me ask a statistician

 

      and then a wordsmith.  Any statistician want to

 

      weigh in on that?

 

                DR. GIBBONS:  I don't think you want to

 

      draw an inference beyond the data that you have.

 

                DR. GOODMAN:  So, are you supporting the

 

                                                               295

 

      way it is currently phrased or suggesting it be

 

      different?

 

                DR. GIBBONS:  I am supporting the last

 

      statement.

 

                DR. FANT:  Basically, what it says is that

 

      the data--it is more difficult to say the data

 

      applies to all nine, and for me, it is easier to

 

      say that based on the data we can't exclude any of

 

      the drugs.

 

                DR. GIBBONS:  The non-exclusion, yes.

 

                DR. GOODMAN:  I would find that more

 

      palatable, too, I would agree.

 

                Does somebody want to try that?

 

                DR. NEWMAN:  I will take a stab.

 

                DR. GOODMAN:  Okay, we are working on it.

 

      In the meantime, we will entertain other comments.

 

                Dr. Newman.

 

                DR. NEWMAN:  I guess I will have to see

 

      it, but I am concerned that that does sound quite a

 

      bit weaker to say that we can't tell for sure that

 

      this drug doesn't cause suicide or suicidality.  It

 

      is true, we need to apply this warning to the whole

 

                                                               296

 

      class, but there is sort of a double negative

 

      there, and I think it would be clearer to say the

 

      warning applies to the whole class.

 

                DR. GOODMAN:  What I was suggesting before

 

      is that this isn't the warning per se.  I think we

 

      can still construct the warning.  I think it would

 

      be more along the lines of what Dr. Marangell had

 

      drafted earlier.  This is just to answer the

 

      specific question to indicate that we are not

 

      talking about just one drug and then we can get

 

      beyond Question 3.

 

                Lauren, do you have something?

 

                DR. MARANGELL:  The data in aggregate

 

      indicate an increased risk of suicidality.

 

      Although there is variability in the results, we

 

      are unable to conclude that any single agent is

 

      free from risk at this time.

 

                DR. GOODMAN:  That's good.  Do you want to

 

      do that one more time?  You may get the Chair of

 

      this committee soon, you know that.

 

                DR. MARANGELL:  No, thanks.

 

                Okay.  Data in aggregate indicate an

 

                                                               297

 

      increased risk of suicidality as previously

 

      defined.  Although there is variability in the

 

      results, we are unable to conclude that any single

 

      agent is free from risk at this time.

 

                DR. GOODMAN:  Give it a chance to be keyed

 

      in.

 

                DR. TEMPLE:  From our point of view, any

 

      of those are fine, because they point directly to

 

      what the next question is going to address, so it's

 

      okay.

 

                DR. LAUGHREN:  As long as it includes a

 

      mention--it would be better to see it in writing,

 

      but I didn't hear mention of pediatric patients in

 

      all indications.

 

                DR. GOODMAN:  We are working on it over

 

      here.

 

                Tana.

 

                DR. GRADY-WELIKY:  Along those lines, I

 

      wanted a point of clarification about are we

 

      talking pediatric use indications or are we talking

 

      pediatric use?

 

                DR. GOODMAN:  We are talking about the

 

                                                               298

 

      studies.  We are back to talking about the studies.

 

      In a sense, this is the second part of the previous

 

      vote, and what we are indicating here is that are

 

      affirmative as already voted by the majority of the

 

      committee, indicates concern about all the drugs in

 

      aggregate or at least that we can't exempt any one

 

      of them individually.  Otherwise, as left, the vote

 

      could look like we were just concerned about one of

 

      the drugs.

 

                DR. MURPHY:  You could just say the data

 

      in pediatric patients.

 

                DR. GOODMAN:  Dr. Irwin.

 

                DR. IRWIN:  I just wanted to be certain in

 

      terms of the definition of pediatrics, what do we

 

      include with that, because it can vary.  Does FDA

 

      have a definition of that?

 

                DR. MURPHY:  Yes, we have a definition

 

      that allows you to be very flexible depending on

 

      the state and country from which your data is

 

      derived.  Again, later, when we get to the warning,

 

      we can be more specific, but I think right now the

 

      phrase "pediatric data" would be sufficient.

 

                                                               299

 

                DR. GOODMAN:  Isn't the NIH definition up

 

      to 21?

 

                DR. PINE:  It matters what it is being

 

      applied for, less than 18 for some definitions, and

 

      less than 21 for others.

 

                DR. MURPHY:  Ours is not up to 21.

 

                DR. GOODMAN:  Yours is not up to 21?

 

                DR. MURPHY:  It is up to 18 in some

 

      guidances.

 

                DR. GOODMAN:  In these particular studies,

 

      were they all up to, but not exceeding, age 18?

 

                DR. MURPHY:  Yes, they were.  Most of

 

      these studies included 17.

 

                DR. GOODMAN:  They included 17, but not

 

      18?

 

                DR. MURPHY:  Is there an 18 in one of

 

      them?

 

                DR. GOODMAN:  I am sorry, I can't hear.

 

                DR. MURPHY:  I think they say to 18.  That

 

      is where you get into argument.

 

                DR. PERRIN:  There were a couple of

 

      studies where a couple kids got in over age 18 by

 

                                                               300

 

      mistake.

 

                DR. HAMMAD:  May I say something?

 

                DR. GOODMAN:  Yes, please.

 

                DR. HAMMAD:  I think I had 85 patients

 

      that were 18 years old out of 4,000, but I did have

 

      it up to 18.

 

                DR. GOODMAN:  Up to and including 18?

 

                DR. HAMMAD:  Exactly, including 18.

 

                DR. IRWIN:  The reason I asked that is

 

      because much of testimony we heard from the public,

 

      a lot of that was in young adults that were beyond

 

      their 18th birthday.

 

                DR. GOODMAN:  Again, that is for our next

 

      statement.

 

                Ms. Griffith.

 

                MS. GRIFFITH:  I agree.  I think that is

 

      problematic in that it varies from state to state.

 

      There are legal definitions of how long a parent

 

      can have control over a child in terms of what that

 

      child will not have to agree to by way of

 

      intervention.

 

                So, I would even recommend we go up to 21

 

                                                               301

 

      because, as of 18, in most of the states in the

 

      U.S., children no longer have to comply with

 

      pharmaceutical interventions, and I think a lot of

 

      people would dismiss the advice once a child turns

 

      18, and it is not warranted.

 

                DR. GOODMAN:  Any further wordsmithing of

 

      the question?  I am satisfied with it.

 

                Dr. Newman.

 

                DR. NEWMAN:  I just think this phrasing is

 

      quite a bit weaker than it was before because when

 

      you say you can't conclude that an agent is free of

 

      risk, you can never ever conclude that any agent is

 

      free of risk, so this just doesn't say very much.

 

                I would rather state it more

 

      affirmatively.  Although there is variability in

 

      the results, we believe these results apply to all

 

      antidepressants in this class.

 

                DR. GOODMAN:  Before you change it, we

 

      need to have some other input on that.

 

                DR. ORTIZ:  This is not the warning.  This

 

      is what we are going to vote on, and it seems like

 

      there is a lot of consensus that this is what we

 

                                                               302

 

      can vote on.

 

                DR. GOODMAN:  Right.

 

                Dr. Fant.

 

                DR. FANT:  If we put the comment in there

 

      "within this class," I am just concerned, you know,

 

      it is going to restrict it to say SSRIs, and the

 

      whole point of this is to include, you know, to be

 

      cognizant of potential risks in drugs that really,

 

      as poor as the data is with other drugs, there is

 

      even less data.

 

                So, the increased risk, we can be as

 

      strong as we want in affirming that and emphasizing

 

      that, but I agree with the whole concept that no

 

      company can enroll 70 kids and say we didn't see

 

      anything, therefore, you guys ought to use us

 

      instead of the other guy.  I think we should not

 

      facilitate that.

 

                DR. GOODMAN:  Dr. Katz.

 

                DR. KATZ:  A couple of things.  First of

 

      all, I think you have to say something about what

 

      kind of agent we are talking about.  I think if you

 

      said any single antidepressant agent, we would know

 

                                                               303

 

      what you mean, which brings me to my second point,

 

      which is this is not language for labeling or

 

      anything else, as someone said.  This is to guide

 

      us, to give us a sense of what you believe about

 

      which sorts of classes and indications the risk

 

      applies to.

 

                I believe it is fair to say that if you

 

      vote on this question, and you add the word

 

      "antidepressant agent," we will know what you mean.

 

                So, I don't know that we need much more

 

      extensive discussion on fine-tuning the question.

 

      We know what you are getting at, I believe, and if

 

      you vote on this with just the addition of the word

 

      "any single antidepressant agent," I think that

 

      would be perfectly fine for our purposes.

 

                DR. GOODMAN:  That is the change I would

 

      recommend, if we could just punch in that "any

 

      single antidepressant agent."

 

                DR. MURPHY:  Dr. Goodman, when you go

 

      around and each person votes again that 30-second

 

      statement, they can make it clear if they have a

 

      problem with the statement.

 

                                                               304

 

                DR. GOODMAN:  That is correct, and we are

 

      talking about the antidepressants that were in the

 

      trials.

 

                DR. TEMPLE:  That's correct.  I thought

 

      that is what you were referring to.

 

                DR. GOODMAN:  That is what we were

 

      referring to.

 

                DR. TEMPLE:  So, we will have a second

 

      question either now or in the next one, it doesn't

 

      really matter about what to do with the drugs that

 

      weren't in the studies.

 

                DR. GOODMAN:  Right.

 

                That is going to be the last comment

 

      before the vote.

 

                Dr. Perrin.

 

                DR. PERRIN:  I am just wondering whether a

 

      slight variation on that issue of risk could be,

 

      and I can't quite have it in front of me now, that

 

      we are unable to conclude that any single

 

      antidepressant agent has particularly low risk of

 

      suicidality at this time.  It might be a more

 

      accurate statement of where we are.

 

                                                               305

 

                DR. GOODMAN:  Is free of increased risk

 

      maybe.  It is free of increased risk.

 

                DR. TEMPLE:  Fine.  That is what that

 

      means.  When say "free of risk," it means free of

 

      increased risk, otherwise, it has no meaning.

 

                DR. GOODMAN:  That's it.  We are going to

 

      go for a vote, and if you have further comments

 

      including about the wording of the question, you

 

      can state them in the 30 seconds that I am going to

 

      allow to be included.

 

                Let's start at the opposite end of the

 

      table this time, first, with Dr. Fant, could you

 

      indicate Yes/No.

 

                We did not add increase because Dr. Temple

 

      said it was implied.

 

                DR. FANT:  Yes.  No additional comments.

 

                DR. PFEFFER:  Yes.  No other comments.

 

                DR. FOST:  Yes.

 

                DR. ORTIZ:  Yes.

 

                DR. MALONE:  Yes.

 

                DR. NELSON:  Yes.

 

                DR. PERRIN:  Yes.

 

                                                               306

 

                DR. GRADY-WELIKY:  Yes.

 

                DR. GOODMAN:  Wait, slow down.  Let me do

 

      the name first.  I think we are eager to cast a

 

      vote.

 

                We have Fant Yes, Pfeffer Yes, Fost Yes,

 

      Ortiz Yes, Malone Yes, Nelson Yes, Perrin Yes,

 

      Grady-Weliky Yes.

 

                Ebert.

 

                DR. EBERT:  Yes.

 

                DR. GOODMAN:  Gibbons.

 

                DR. GIBBONS:  Yes.

 

                DR. GOODMAN:  Pine.

 

                DR. PINE:  Yes.

 

                DR. GOODMAN:  Bronstein.

 

                MS. BRONSTEIN:  Yes.

 

                DR. GOODMAN:  Rudorfer.

 

                DR. RUDORFER:  Yes with a comment.  First

 

      of all, I wonder if--I guess it's too late to go

 

      back, but--

 

                DR. GOODMAN:  You guessed right.

 

                DR. RUDORFER:  --if a clarification of the

 

      phrase "increased risk" would be helpful.  Again, I

 

                                                               307

 

      think we have agreed that an increased risk is

 

      likely to be small, and I wonder how that should be

 

      conveyed, because "increased" covers a fairly wide

 

      range.

 

                The other thing, if I have a few seconds

 

      left, just to reiterate my concerns.  I agree

 

      certainly with the spirit of this statement, that

 

      we have seen that signal across all the drugs.

 

                My concern relates, if I may use an

 

      example, to the two citalopram studies we reviewed.

 

      An American study found efficacy in major

 

      depression in a pediatric sample, and found no

 

      suicidality signal.

 

                The European study combined data from

 

      seven different countries, which I did not find

 

      methodologically attractive, found no efficacy

 

      compared to placebo, and did find a positive

 

      suicidality signal.

 

                S-citalopram, we have no data on the

 

      related compound.  So, again, my overarching

 

      concern remains the fact that I think this is very

 

      much still a work-in-progress.

 

                                                               308

 

                Thank you.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Goodman, Yes.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  Yes with the understanding

 

      that this statement applies only to the SSRI agents

 

      that we have been discussing.  It doesn't say SSRI

 

      anywhere.

 

                DR. GOODMAN:  Let me clarify.  It applies

 

      to all the compounds that were studied in the

 

      trials, which includes several non-SSRIs.  When you

 

      add the non-SSRIs, the hazard ratio gets bigger,

 

      for what that is worth.

 

                DR. CHESNEY:  In other words, we are

 

      including imipramine and--

 

                DR. GOODMAN:  No, no, just the ones that

 

      were involved in the clinical trials that we

 

      reviewed, that were part of Hammad re-analysis.

 

                DR. CHESNEY:  Which were the non-SSRIs?

 

                DR. GOODMAN:  Venlafaxine.

 

                DR. CHESNEY:  All right.  The answer is

 

      Yes.

 

                                                               309

 

                DR. GOODMAN:  I am sorry.  Let me re-ask

 

      your vote, Dr. Chesney, based upon that

 

      clarification.

 

                DR. CHESNEY:  Yes.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Yes.

 

                DR. GOODMAN:  Griffith.

 

                MS. GRIFFITH:  Yes.

 

                DR. GOODMAN:  Leslie.

 

                DR. LESLIE:  Yes.

 

                DR. GOODMAN:  Robinson.

 

                DR. ROBINSON:  Yes.

 

                DR. GOODMAN:  Marangell.

 

                DR. MARANGELL:  Yes.

 

                DR. GOODMAN:  Irwin.

 

                DR. IRWIN:  Yes.

 

                DR. GOODMAN:  Dokken.

 

                MS. DOKKEN:  Yes.

 

                DR. GOODMAN:  Newman.

 

                DR. NEWMAN:  Yes.

 

                DR. GOODMAN:  Wells.

 

                DR. WELLS:  Yes.

 

                                                               310

 

                DR. GOODMAN:  Pollock.

 

                DR. POLLOCK:  Yes.

 

                DR. GOODMAN:  O'Fallon.

 

                DR. O'FALLON:  Yes.

 

                DR. GOODMAN:  Santana.

 

                DR. SANTANA:  Yes.

 

                DR. GOODMAN:  It was unanimous this time.

 

      We had 27 respondents, all Yes.

 

                Do people want a short break?  Yes.

 

                [Break.]

 

                DR. GOODMAN:  I think we have made a great

 

      deal of progress.  We have two remaining questions.

 

                As currently constructed, neither of those

 

      questions require a vote.

 

                Dr. Katz.

 

                DR. KATZ:  Yes, it is very important for

 

      us to have you vote on an extension of the question

 

      you just voted on, which is whether or not this

 

      should apply to all other antidepressants or

 

      whether you simply want to limit whatever warning

 

      or whatever conclusion we draw to just the ones

 

      that were studied.

 

                                                               311

 

                My understanding is that in this question,

 

      the one you voted on, you limited it to

 

      consideration of the drugs studied.

 

                DR. GOODMAN:  That is correct.  Let's have

 

      a discussion and see if others around the table

 

      agree.

 

                Dr. Gorman.

 

                DR. GORMAN:  For future drugs that are

 

      coming down the pike, the Food and Drug

 

      Administration, under the Pediatric Research Equity

 

      Act, has the ability to demand antidepressant

 

      studies in children prior to their release.

 

                I don't think there can be any doubt after

 

      the numbers we heard today that they will be used

 

      in more than 50,000 patients and have the potential

 

      to give a significant therapeutic advance, because

 

      at this point, we only have one drug that is

 

      approved.

 

                So, I think for drugs coming down the

 

      pike, I think there is the ability within the FDA

 

      to ask for that information, and since I am not a

 

      voting member of the committee, I will leave the

 

                                                               312

 

      discussion about what to do with the previously

 

      approved drugs alone.

 

                DR. GOODMAN:  Dr. Wang.

 

                DR. WANG:  Yes.  It seems if you exempt

 

      any drugs, new or otherwise, you set up this

 

      perverse incentive, particularly for the new drugs,

 

      to either do no studies or to do poorly conducted

 

      studies where they don't ascertain cases or

 

      underpower them, so I think to prevent that

 

      perverse incentive, you have to put the onus on

 

      them to show that they are the exception.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  While I might want to have a

 

      similar strategy across all antidepressants, I

 

      think it is really not appropriate for this

 

      committee to take a stand against antidepressants

 

      for which we have not reviewed the data.

 

                I am very uncomfortable saying that we

 

      know much about them when we really haven't seen

 

      the data on them.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  Although agreeing with the

 

                                                               313

 

      prior point, my concern would be the message that

 

      would be sent if you didn't apply this across all

 

      drugs, and my own preference would be to have a

 

      class risk warning and then any preferential

 

      treatment ought to be on the efficacy side, so that

 

      you then have drug-specific labeling under the

 

      efficacy component, which would then begin to

 

      differentiate, so that individuals can be informed

 

      about the risk-benefit ratio by looking and

 

      comparing those two sections, which would be one

 

      way to direct people appropriately as opposed to

 

      inappropriately.

 

                DR. GOODMAN:  Dr. McGough.

 

                DR. McGOUGH:  Just again, what we are

 

      talking about here is patient safety, and I think

 

      it is appropriate that we err on the side of being

 

      in favor of that, and even though we haven't

 

      reviewed data specifically, I think it is an

 

      unanswered question, and as such, I think it is

 

      appropriate to apply it generally to the class of

 

      antidepressant drugs.

 

                DR. GOODMAN:  Dr. Laughren.

 

                                                               314

 

                DR. LAUGHREN:  Just to clarify what we are

 

      planning to do with the general warning that we

 

      have already implemented for 10 newer generation

 

      antidepressants, we are planning on extending this.

 

      In fact, it has already been extended to some of

 

      the older drugs, some of the tricyclics.

 

                Our plan is to extend it to all, and the

 

      question here is whether or not we should also, if

 

      we are thinking about adding new language to that

 

      warning, suggesting that we have now established

 

      causality, whether that new language should also

 

      apply to all antidepressants.

 

                Again, I think this concern has been

 

      expressed by several members, that if you don't do

 

      that, you are, in effect, directing clinicians to

 

      use those older drugs.

 

                DR. GOODMAN:  Dr. Leslie.

 

                DR. LESLIE:  Again, my concern is not just

 

      the older drugs, but the newer drugs, because

 

      Cimbalta, which is coming out, is most comparable

 

      to Effexor, which had the highest relative risk,

 

      and I again would be very concerned with the

 

                                                               315

 

      marketing directly to patients and the heavy

 

      marketing to clinicians, that it would be marketed

 

      as the only drug of this class without a label, and

 

      would thus again push clinicians in that direction.

 

                DR. GOODMAN:  Dr. Marangell, did you have

 

      a draft of the question that we were composing

 

      before, that represented more of a general warning?

 

      I don't think we keyed it in.  I don't think it was

 

      saved.

 

                I think where we are in the discussion,

 

      let me remind people, we are in Question 4, and we

 

      are talking about recommendations regarding

 

      additional regulatory actions.

 

                Since the last meeting, warnings were

 

      issued about a group of symptoms that may be part

 

      of what some have labeled inactivation syndrome,

 

      that were proven to be precursors of suicidality.

 

                So, I think, in part, the question before

 

      us is whether we want to extend that now to

 

      conclude that there is a suicidality risk.  In the

 

      last warning that was issued, it said that there

 

      was no established connection between the

 

                                                               316

 

      medications and suicidality, and we have obviously

 

      been deliberating and voting on that question.

 

                We are really talking about what

 

      additional warnings need to be posed that go beyond

 

      the activation symptoms or syndrome that was

 

      defined previously.

 

                Dr. Temple.

 

                DR. TEMPLE:  Whether you do it as part of

 

      Question 3 or part of Question 4, we unequivocally,

 

      as you have already indicated, need to know whether

 

      the warning, if it is modified, needs to be in the

 

      labeling for all antidepressants or just the ones

 

      that were in the study including tricyclics, MAO

 

      inhibitors, duloxetine, and so on.

 

                So, I don't know whether that is a 3

 

      question or a 4 question, but once you answer the

 

      question about any additional warning language, we

 

      have to know who you think that applies to.

 

                DR. GOODMAN:  Dr. Malone.

 

                DR. MALONE:  I think it applies to all of

 

      the drugs.  Was it the Jick study that really

 

      didn't find any difference between the risk for

 

                                                               317

 

      different classes of drugs. I think that is one

 

      reason to apply it to, say, the tricyclics which

 

      were included in that study.

 

                Also, some of the older drugs, like the

 

      tricyclics and MAO inhibitors, are much more

 

      dangerous, so if you did become suicidal, you would

 

      actually have the drug with you, that you could use

 

      to commit suicide easily.

 

                I agree that new drugs, as they come on

 

      the market, you wouldn't want to automatically give

 

      them this undue edge that they don't have this

 

      warning.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  I would just like to say

 

      that when I made my comment before the break, I

 

      wasn't thinking of all these other factors, and on

 

      reconsideration, I think that these are excellent

 

      points.

 

                I think that the wording was correct that

 

      it is well recognized that suicide and suicidal

 

      behavior emerges during the early stages after

 

      treatment, and because we don't have the specific

 

                                                               318

 

      studies that address this issue, it may be

 

      reasonable to assume that this would apply to all

 

      antidepressants at this point in time until proven

 

      otherwise.

 

                Somebody made that point, put the onus on

 

      the company to show that they did not fall in that

 

      ballpark.  So, whereas before the break, I was very

 

      alarmed that we were going to be asked to do some

 

      things we knew nothing about, I think I now

 

      understand the reasoning.

 

                Thank you.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Pine.

 

                DR. PINE:  I think it is important to

 

      recognize, speaking again as a child psychiatrist,

 

      that there is a very legitimate concern about

 

      discouraging people, and physicians in particular,

 

      from moving away from the 23 plus 1, the agents

 

      that we have been discussing, to tricyclics

 

      antidepressants.

 

                I think that, at least from my own

 

      perspective, I think we want to think kind of

 

                                                               319

 

      ahead, and I think we do obviously based on what

 

      the FDA said, and based on other information, say

 

      something about the use of those agents.

 

                Historically, there actually is a fair

 

      amount of data on those agents, although not nearly

 

      the amount of data as we have reviewed for SSRIs,

 

      and it is current standard of care in child

 

      psychiatry not to use those agents, and that is

 

      really based on two things.

 

                That is based on, number one, the fact

 

      that a number of meta-analyses have shown that the

 

      agents are not effective over placebo, and there

 

      has not been a single study that demonstrated

 

      efficacy for a tricyclic antidepressant or an MAOI,

 

      number one.

 

                Number two, there was a lot of concern in

 

      the 1990s about the cardiotoxicity of these agents

 

      in children, not only the cardiotoxicity in

 

      overdose, which I think there is little debate

 

      about, but even questions about cardiotoxicity when

 

      the agents were used appropriately in therapeutic

 

      doses.

 

                                                               320

 

                So, I think, on the one hand, it is very

 

      important to say that it would not be good if

 

      physicians were to move from the newer agents to

 

      the older agents, on the one hand, on the other

 

      hand, probably the strongest thing we could say

 

      would not be to say, well, we don't know whether

 

      these drugs cause suicidality or not, the strongest

 

      thing we could say is that there are plenty of

 

      reasons to discourage this.

 

                One of the might be that the agents are

 

      associated with suicidality like the SSRIs,

 

      however, the cardiotoxicity and the lack of

 

      efficacy data, I think are stronger reasons not to

 

      move that way.

 

                DR. GOODMAN:  Dr. Gibbons, did you have

 

      another question or comment?

 

                DR. GIBBONS:  This is a very tricky issue.

 

      The issue is we don't want to go beyond the data

 

      that we have, but on the other hand, with the

 

      exception of one of these agents, we haven't shown

 

      any adverse effects on a drug-by-drug basis.

 

                Now, a new drug comes out on the market. 

 

                                                               321

 

      Given current regulatory practices, there will not

 

      be enough data to show a risk ratio of 1.5 in that

 

      drug, so the conclusion will be that there is no

 

      association, and they may get an exemption.

 

                On the other hand, you know, so what you

 

      are doing is you are holding a much higher standard

 

      to the drugs that were looked at in these 21

 

      studies, for which we were able to pool over drugs

 

      and show an effect.

 

                I suppose you could set up a situation in

 

      which a new drug or an old drug that was not part

 

      of the 21 could, in fact, be removed from the list

 

      if the study was powered, if there was enough data,

 

      so that they could, in fact, identify a risk ratio

 

      in the magnitude that we are looking at here, in

 

      the 1.5 range or so, but they would have to get a

 

      hell of a lot of patients to do it.  It might not

 

      even be practical to do that.

 

                So, it is really a conundrum of what to

 

      do.

 

                DR. GOODMAN:  Dr. Fant.

 

                DR. FANT:  To address the question that

 

                                                               322

 

      was posed about extending to other drugs, I think

 

      based on the data that we have looked at here, at

 

      least from what I have seen it is impossible to

 

      tell if the endpoints that we saw, if the signals

 

      that we saw were due to drug-specific effects or if

 

      they were due to factors intrinsic to the disease

 

      process in the patient that was perturbed by

 

      treatment by whatever mechanism.

 

                It is kind of hard to sort out which is

 

      the major factor in that regard.  Until that can be

 

      sorted out, until you have some information that

 

      suggests, on a mechanistic basis, that it is

 

      related to a drug-specific effect, I don't think

 

      you can exclude any drug that impacts on

 

      depression.

 

                DR. GOODMAN:  Take a moment and look at

 

      the question or the statement, not a question, but

 

      the statement as it is proposed.

 

                DR. TEMPLE:  Is that intended to be

 

      labeling language?

 

                DR. GOODMAN:  My understanding is that it

 

      is not our job to write the labeling language for

 

                                                               323

 

      the FDA.  That is one of the reasons I wasn't sure

 

      that we needed to take a vote, because I don't

 

      think that we should be writing these for you, but

 

      I think it does help to have something in writing

 

      here to communicate to the FDA how broad our

 

      concerns are.

 

                Dr. Temple.

 

                DR. TEMPLE:  So, is this your proposal?

 

                DR. GOODMAN:  Two committee members have

 

      proposed this.

 

                DR. TEMPLE:  My initial response to that

 

      is it doesn't really say that you should assume

 

      this risk applies to all drugs.  It says you should

 

      use caution in pediatric patients.  Well, we have

 

      sort of said that already.  It doesn't quite say

 

      you should worry about that risk in pediatric

 

      patients.

 

                We can work on it, too, but we are

 

      interested in some view of how explicit we really

 

      should try to be even if you don't write the exact

 

      words.  That one is not so explicit perhaps.

 

                DR. MARANGELL:  I think we are just trying

 

                                                               324

 

      to put forward, kind of the broadening concept of

 

      including both prior agents and future agents that

 

      are categorized as antidepressants and where to go

 

      from there.

 

                DR. GOODMAN:  Dr. Katz.

 

                DR. KATZ:  Fine.  I think we certainly get

 

      the thrust of that, we appreciate it.  One question

 

      that I think we would like you to explicitly

 

      address is whether or not you think this is the

 

      sort of thing that belongs in a black box, which is

 

      sort of another level of communicating risk.

 

                Right now it is a warning, the major

 

      language is in the warning--the language is another

 

      section--but the major language is in the Warning

 

      Section.  Do you think this arises to the level of

 

      a black box warning?

 

                DR. GOODMAN:  Let me ask Dr. Nelson to

 

      comment.

 

                DR. NELSON:  Let me comment on that, and

 

      then just make a comment on the language of the

 

      second sentence.  I think the difficulty with a

 

      black box warning, at least my interpretation, and

 

                                                               325

 

      maybe it is based on my practice, is if I see a

 

      black box warning, I just don't do it, for example,

 

      propofol for long-term sedation in pediatric ICUs,

 

      no longer done because of the warning.

 

                So, I think a black box warning may drive

 

      people away from drugs that they might otherwise

 

      appropriately use as opposed to a warning that is

 

      placed upfront in the Warning Section.

 

                My difficulty with this language, and I

 

      know we are not going to talk language, but I would

 

      try to be more specific.  I mean one of the more

 

      difficult things to communicate, I think even to

 

      physicians, is risk data, and I kind of liked the

 

      slide that we were provided, that could even in

 

      this case, communicate data where you could have

 

      something like out of 100 patients treated, 2 to 3

 

      patients on average will have an increase in

 

      suicidal behavior or ideation after initiation or

 

      changes in treatment, period.

 

                So, people say, well, what does this

 

      really mean, it means that if they give 100 people

 

      the drug, they have got to watch out 2 or 3 times. 

 

                                                               326

 

      That, to me, is useful information, and I would

 

      advocate labeling that provides that kind of

 

      information.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I am just trying to interpret

 

      the last statement, which is that we should give

 

      some quantitative estimate of what the nature of

 

      the risk is.

 

                DR. NELSON:  Well, it is more than that,

 

      because I think it is an issue of percentage.  I

 

      mean there is a lot of literature on whether risk

 

      is best communicated as numbers out of 100 versus

 

      percentages versus other things, so I am explicitly

 

      saying I find the most useful thing is real people

 

      out of a real cohort of people helps me know what

 

      the universe is.

 

                DR. TEMPLE:  I would add that we should

 

      probably tell people what the baseline risk is and

 

      what the increase compared to baseline is.

 

                DR. NELSON:  I would also link this to

 

      similar kind of data under the efficacy, so you are

 

      right.

 

                                                               327

 

                DR. GOODMAN:  Dr. Rudorfer.

 

                DR. RUDORFER:  A couple of questions.

 

      First, about the tricyclic issue.  My recollection

 

      is there is some language already for the older

 

      antidepressants related to risk of possible

 

      clinical worsening early in the course of

 

      treatment.  I mean I am just wondering, if

 

      something doesn't exist, or even if it could be

 

      moved within the labeling to be comparable to

 

      placement, say, of the newer--

 

                DR. GOODMAN:  Tom.

 

                DR. LAUGHREN:  Again, let me reiterate

 

      what I suggested earlier.  Our plan is to extend

 

      this current, much broader warning statement that

 

      is now only in these 10 current generation drugs to

 

      all antidepressants including all the tricyclics,

 

      all the MAOIs.  Some of them actually already have

 

      it.

 

                So,  you are right, there is that old

 

      language in the tricyclics.  That is going to be

 

      changed to the newer language, and really the

 

      question here is whether you are comfortable with

 

                                                               328

 

      us extending this additional view, that now we have

 

      established causality for suicidality to all

 

      antidepressants, not just these nine drugs that

 

      were studied in these trials, and pediatric

 

      patients.

 

                DR. RUDORFER:  Do I understand correctly,

 

      Tom, in the newer warning, that is where the

 

      description of the behavioral activation is

 

      mentioned, because again, what I am wondering is,

 

      if that specific language really should be

 

      applicable to the tricyclics.

 

                I mean at our February meeting, we were

 

      describing a syndrome that I think the sense of the

 

      committees was that that was more specific to the

 

      newer generation drugs.

 

                DR. LAUGHREN:  The same kinds of behaviors

 

      are seen in SSRIs, in SNRIs.  I think an argument

 

      could be made. I mean obviously, there is a lot of

 

      anecdotal data that the older drugs in some

 

      patients have the same kinds of symptoms, so I mean

 

      my inclination, in fact, some companies have

 

      already done it on their own.  They have added this

 

                                                               329

 

      new language to certain older drugs.  It has

 

      already happened voluntarily by companies.

 

                DR. RUDORFER:  Just a follow-up question,

 

      semi-rhetorical.  I had asked this morning about

 

      whether we know yet the impact of the label changes

 

      from March, and my understanding is we don't know

 

      yet.

 

                Is there any rationale to giving that

 

      additional time to see the impact of that change

 

      before we make another change?

 

                DR. LAUGHREN:  You mean before we extend

 

      the language to the older drugs?

 

                DR. RUDORFER:  No, I mean before we change

 

      the warning on the newer drugs.

 

                DR. GOODMAN:  Let me try it.  My opinion

 

      on that would be that now that the committee has

 

      decided that there is an association, at least

 

      within the trials, that I think the language needs

 

      to be extended to association has been established

 

      for suicidal ideation and behavior, however we want

 

      to say it.  I think it has to be very careful how

 

      we say it apropos of the earlier discussion.  I

 

                                                               330

 

      think we need to define what we mean by

 

      suicidality.

 

                I think our present discussion is whether

 

      it should be extended to the other and to the

 

      present, and I don't think our discussion is over

 

      yet, but I think probably we are leaning in the

 

      direction of yes, extending it and erring on the

 

      side of safety.

 

                DR. LAUGHREN:  Just to clarify, the

 

      current language in this warning that was

 

      implemented as of our March advisory, states as

 

      follows:  "A causal role for antidepressants in

 

      inducing such behaviors has not been established."

 

                So, the question that we have been

 

      addressing here this afternoon is whether or not we

 

      can now say that the causality has been

 

      established, and the further question of whether we

 

      should extend that beyond these nine drugs to all

 

      antidepressants.

 

                DR. GOODMAN:  Tana.

 

                DR. GRADY-WELIKY:  I just wanted to

 

      comment on the question of the warning or black box

 

                                                               331

 

      with whatever we decide on this, and I would like

 

      to agree with Dr. Nelson that certainly having a

 

      warning, and my preference would be for all

 

      antidepressants, would be an important thing to do,

 

      but I would caution against using a black box

 

      warning because it would steer many clinicians away

 

      from using these agents, and as we heard yesterday

 

      from both patients and clinicians, that for many

 

      people, antidepressants are very useful treatment.

 

                DR. GOODMAN:  Dr. Mehta.

 

                DR. MEHTA:  Just a clarification from Dr.

 

      Laughren.  If you are going to extend it to the old

 

      drugs, I guess you will also extend the same

 

      warning to all the new drugs, is that right?

 

                DR. LAUGHREN:  Yes.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I just want to remind

 

      everybody that one of the major reasons for using a

 

      black box or a box is that you think there is

 

      something that can be done to avoid the trouble

 

      that you are telling people about.

 

                Just telling people that something

 

                                                               332

 

      horrible has its own value, but it seems

 

      particularly important to get people's attention

 

      when there is something we want you to do.

 

                In this case, there is something that we

 

      want you to do.  We want you to pay attention, not

 

      put the people out to pasture for three weeks and

 

      never see them again.

 

                So, we certainly are cognizant of the

 

      effect this can have on prescribing, and certainly

 

      don't want to do harm, but I just want to remind

 

      everybody that this is potentially remediable by

 

      seeing the patient, talking to them, being alert

 

      for these things, one of the main reasons for

 

      thinking that you should emphasize things by a box.

 

      I just want to be sure that is on the table.

 

                DR. GOODMAN:  How do you deal with the

 

      fact that with the exception of fluoxetine and some

 

      of the other medications in some of the anxiety

 

      disorders, these are off-label uses, how does that

 

      gibe with the general use of a black box where, in

 

      fact, you don't have an indication to start with?

 

                DR. TEMPLE:  It's a really good question

 

                                                               333

 

      and requires great delicacy, but the box is about

 

      the warning, and we have on occasions warned people

 

      about things even though the use wasn't approved,

 

      so you have to be very careful.  But if it's--what

 

      is an example--the hyperpyrexia syndrome.

 

                DR. KATZ:  One example, we have done this,

 

      as Bob says, in cases, and usually, what we say is

 

      here is a risk--specifically in pediatric

 

      patients--here is a risk in pediatric patients.  We

 

      remind you that this drug is not approved for use

 

      in pediatric patients, effectiveness has not been

 

      demonstrated.

 

                So, we tell people it is not approved, we

 

      don't know if it works, but here is a particular

 

      risk.  So, there is certainly precedent for doing

 

      that, and we have done that.

 

                DR. GOODMAN:  Ms. Bronstein.

 

                MS. BRONSTEIN:  If I heard nothing from

 

      the public, it was they want to be warned.  They

 

      want to hear the risk.  I was thinking of big bold

 

      letters, not the black box.  From what I have

 

      understood, the black box is used for really dire

 

                                                               334

 

      situations, and while suicide is a dire situation,

 

      what we are asking is that they monitor patients

 

      closely, that they ask their families to

 

      participate in that monitoring process.

 

                So, I see this more in the realm of

 

      informed consent, and I don't know what we have

 

      done in the past for more of an informed consent

 

      process.  Have we any drugs that we require an

 

      informed consent?

 

                DR. TEMPLE:  We had a few where we did

 

      that.  My own personal view is that gaining

 

      consent, after all, you have to open your mouth to

 

      take it, is a little funny.  What we have moved

 

      more toward, but not entirely, is something where

 

      there is a required distribution of a piece of

 

      paper that says these things to the patient and

 

      some acknowledgment that they have read it.  It's a

 

      little different concept for consent.

 

                But we have done that in particular cases.

 

      It is very burdensome.  If people are worried about

 

      discouraging the use of the drugs, they need to put

 

      that in--

 

                                                               335

 

                DR. GOODMAN:  We are talking about

 

      children.  It's assent, isn't it, and it is more

 

      complicated?

 

                DR. TEMPLE:  Well, whether it is a matter

 

      of displaying what the risk is in a piece of paper

 

      that someone acknowledges having received, or you

 

      want to call it consent, it is sort of the same

 

      thing, but it's a big step.

 

                We have done it for thalidomide and things

 

      like that, but it is a very big step.  You have to

 

      balance what effect you think it has on the use of

 

      the drug.

 

                DR. GOODMAN:  Dr. Trontell.

 

                DR. TRONTELL:  Just to expand on Dr.

 

      Temple's remarks, informed consent has been used by

 

      the Agency for drugs other than ones with the

 

      extensive systems like thalidomide and clozapine.

 

      It is used for several Parkinson's disease agents,

 

      as I recall.

 

                It is often called, some call it a patient

 

      agreement.  It is some way of setting forward some

 

      kind of written system recorded often in the

 

                                                               336

 

      patient's chart, that basically, tries to again

 

      assure that this conversation occurs between the

 

      provider and the patient.

 

                So, again, it clearly is one area where we

 

      are again stepping into that therapeutic

 

      relationship, where some people take exception to

 

      the Agency doing that.

 

                I had actually one additional remark, if I

 

      could make, relative to boxed warnings.  In

 

      general, the Agency often uses those in context

 

      where the adverse event is associated with

 

      fatalities.  Clearly, suicidal behavior can result

 

      in that.

 

                An incidental consequence of that is that

 

      products that carry boxed warnings also have to

 

      carry that in their advertising, and quite

 

      frequently, that makes it quite difficult to

 

      explicitly advertise that product in

 

      direct-to-consumer advertising.

 

                DR. GOODMAN:  That you for that ad

 

      information.  How about in sampling, would it

 

      affect detailing, sampling?

 

                                                               337

 

                DR. TRONTELL:  The requirement is if you

 

      carry a boxed warning, that boxed warning has to go

 

      on all the materials that are used for advertising.

 

      I am not aware that it would impede sampling, but

 

      effectively, the advertising that goes into popular

 

      magazines or on the television can't easily

 

      accommodate that, so you don't get specific

 

      products typically advertised that have those

 

      warnings.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Temple.

 

                DR. TEMPLE:  You can't use reminder ads

 

      either.

 

                DR. GOODMAN:  I am sorry, I missed that.

 

                DR. TEMPLE:  You can't do something called

 

      a reminder ad.  That is where you just give the

 

      name and don't say much about the drug.  You can't

 

      do those anymore if there is a box.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  I think those would be big

 

      pluses.  As we move into the effects of the boxes

 

      and what effects that might have on prescribing, I

 

                                                               338

 

      think we have to come back to the issue of

 

      efficacy.

 

                We have I think very strong evidence of

 

      harm and really not very good evidence of efficacy,

 

      and although I know many practitioners are

 

      convinced that these drugs work, if you look very

 

      closely at the TADS trial, just as an example, at

 

      the Childhood Depression Rating Scale, the

 

      improvement with placebo was 19 points, and the

 

      improvement with the drug was 23.4 points.

 

                You bring people in, you start a

 

      medication, and you see an improvement, you are

 

      very, very likely to believe that the drug is

 

      effective, and the reason why we do randomized,

 

      double-blind trials is because personal experience,

 

      however compelling, is not a reliable way to tell

 

      whether drugs work.

 

                In the study where they worked, in the

 

      TADS, the improvement over placebo was really very,

 

      very small, and I would say not detectable by a

 

      clinician treating individual patients.

 

                So, it would not be that bad if use of

 

                                                               339

 

      these drugs were diminished, I think, because we

 

      don't know whether they actually help most patients

 

      when you put together all the data, and I think it

 

      is very important that this conversation about the

 

      risks take place, so I would favor some sort of

 

      informed consent process.

 

                DR. GOODMAN:  I think it was appropriate

 

      for you to remind us of the efficacy issue as we

 

      are starting to look about benefit, as well as

 

      risk, as we make recommendations and regulatory

 

      actions.

 

                I agree and I think many of us, including

 

      myself, have said this in the room today and

 

      yesterday, that there is a dearth of data on

 

      efficacy.  We do have the positive trials that were

 

      submitted, that led to the indication for

 

      fluoxetine in major depression.

 

                We do have the TADS data, and actually, I

 

      may have misspoken yesterday when I said that there

 

      was no difference between fluoxetine and placebo on

 

      the Children's Depression Rating Scale.  That is

 

      only true by one analysis, but if you look at mean

 

                                                               340

 

      comparisons, although they are small, you are quite

 

      right, that the magnitude of the difference is

 

      small, I think they still reach statistical

 

      significance.

 

                Where we lack the most data is on

 

      long-term benefit.  I think what you are hearing,

 

      what we heard yesterday from some of the

 

      clinicians, what you are hearing from some of the

 

      people in this room who have treated children with

 

      antidepressants, sure, it is contaminated by bias

 

      and expectation.  There is no question.

 

                I have been humbled before in terms of the

 

      limitations of my own ability to discern an effect

 

      in the absence of a placebo-controlled study, I

 

      grant you that, but at the same time, we are

 

      dealing with drugs that have been out there a long

 

      time, numerous seasoned clinicians, and there is a

 

      very powerful impression among many, and from the

 

      consumers themselves, that in some cases, this has

 

      made a huge difference.

 

                So, I worry that if we ignore that

 

      information, even though it is not good data in the

 

                                                               341

 

      way we would like to see it, that we may risk a new

 

      increase of suicidality on the back end.

 

                We are doing a lot here to protect it on

 

      the front end, but we haven't done the kind of

 

      studies that were recommended before, earlier by

 

      Dr. Temple, and doing a discontinuation study, and

 

      I agree we don't know the answer, but it is

 

      conceivable that there will be some patients that

 

      will be deprived of those medications that may be

 

      life-saving and may even be inclined to come off

 

      medications and have a relapse that will lead to

 

      suicidal behavior.

 

                I welcome other comments.

 

                Dr. Nelson.

 

                DR. NELSON:  Although I agree with you,

 

      Tom, I would be concerned that saying that alone

 

      without including drug-specific efficacy data will

 

      send the wrong message, and i think there needs to

 

      be a balance, and I would be curious how my

 

      psychiatric colleagues would react to the following

 

      suggestion, that if perhaps in fluoxetine, you

 

      included the efficacy data, which is the only drug

 

                                                               342

 

      that, in fact, has passed that bar, would it be a

 

      bad thing if, in fact, practitioners, who are not

 

      child psychiatrists, who lack the knowledge to be

 

      able to then, if someone fails fluoxetine, to make

 

      an appropriate choice of any of the other agents.

 

                If, in fact, what happened in general

 

      practice, family practice, general pediatrics, is

 

      fluoxetine was the first drug that would always be

 

      chosen, hopefully, under appropriate monitoring

 

      given the risk, but then if you failed that, you

 

      need help, that it is not something where you will

 

      go to multiple other drugs and start running down

 

      the list, thinking that if you just found the right

 

      one, you would be okay.

 

                So, my question is can we custom craft the

 

      labeling where you might drive that kind of medical

 

      practice, and if we could, would that be a good

 

      thing?

 

                DR. GOODMAN:  Dr. Malone.

 

                DR. MALONE:  I think it would be a good

 

      idea to customize the labeling.

 

                DR. GOODMAN:  I am sorry, I missed your

 

                                                               343

 

      point.

 

                DR. MALONE:  I think it would be good to

 

      customize the labeling, but in addition, fluoxetine

 

      is a positive study.  As a clinician, when you look

 

      at the PDR, I think it would be very helpful to

 

      have some balanced statement regarding the number

 

      of studies that were done, say, for depression with

 

      a given agent, and the number of studies that were

 

      positive and negative, because I mean I think it

 

      has been said before, when you look at the PDR and

 

      you see a statement that it is not indicated for

 

      under 18, it is quite a different thing than to

 

      know that there were five studies done and none of

 

      them were positive.

 

                You could add statements that negative

 

      studies don't mean it doesn't work, but it would be

 

      helpful for me, as a clinician, to be able to read

 

      that information.

 

                DR. GOODMAN:  Dr. Pine.

 

                DR. PINE:  I just have a couple of

 

      comments related to the discussions that have been

 

      going on, the first of which is, you know, we

 

                                                               344

 

      really have not talked about the efficacy data, and

 

      I think it is very important to spend a fair amount

 

      of time talking about that.

 

                The second thing is, for reasons that I

 

      will go into in a second, I would agree with some

 

      of the sentiments related to concern about adding a

 

      black box warning, that I would be concerned about

 

      that, and I think probably some of the most

 

      compelling data, at least to think about, is to

 

      look carefully at the efficacy data for fluoxetine.

 

                There are a couple of things to say.  The

 

      first is to remember that based on the efficacy

 

      data alone, even before we had the TADS trial, that

 

      those data were felt to be sufficiently compelling

 

      to justify an indication in pediatric depression.

 

                Now, the second thing to say about the

 

      fluoxetine data in general is at least when I look

 

      at the magnitude of the effect in that study,

 

      relative not only to other effects in pediatric

 

      depression, but relative to other effects of

 

      psychotropic agents in many disorders, I think one

 

      would not call that to be a small effect.

 

                                                               345

 

                In fact, I think the investigators and the

 

      journal itself called it a moderate effect, which I

 

      think is a fair summary of that effect.

 

                The third thing to say is, if I am

 

      correct, although I would like to hear from the FDA

 

      about this, thus far the only warnings that have

 

      been given make no explicit statements about

 

      causality, number one, and then number two, make no

 

      explicit differentiation between the potential for

 

      the risk being greater in children relative to in

 

      adults.

 

                I think just based on what I have heard,

 

      clearly those two statements could be made

 

      relatively strongly that there is something

 

      different going on in kids than adults, at least

 

      based on the level of review that we have had that

 

      hasn't been said, and it is pointing to causality.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  Well, we still believe the

 

      general warning about paying attention to people

 

      still should apply to adults and children, we don't

 

      want to change that, but as was said, it now says

 

                                                               346

 

      causal relationships not established, and you don't

 

      think and we don't think that that is a true

 

      statement anymore about the pediatric population.

 

                So, the thought would be to add, modify,

 

      something to convey what the new findings are.

 

                I want to make one other comment.  There

 

      are various ways of communicating with patients and

 

      their families.  Some kind of form to sign is one,

 

      but there also is patient labeling that can be made

 

      to go to every patient who gets prescribed one of

 

      these drugs.

 

                We have done that for a very large number

 

      of drugs.  They are called Med Guides at present,

 

      and they can be focused on the particular concerns

 

      that one has and the risks that there are, and we

 

      would obviously have to dance around the fact that

 

      the drug isn't indicated for children, but there

 

      are still ways of doing that.

 

                So, that is not causing a form to be

 

      handed out in the office, but it is a way of

 

      communicating.  As I said before, the probability

 

      that that will be distributed, we think goes up

 

                                                               347

 

      when it becomes part of a package, part of a unit

 

      of use package.

 

                DR. MURPHY:  But we need to make clear

 

      that the Med Guide is different than the patient

 

      package insert, that people often think about that

 

      comes with the regular label.

 

                What might be helpful to think about,

 

      there is two things, what you want to warn about,

 

      where you want to put it or how you want to put in

 

      the label, black box, warnings, precautions, people

 

      talk about bolding versus how do you want to get

 

      the information out to others besides the learned

 

      intermediary.

 

                That is where Dr. Temple is talking about,

 

      you know, do you want it just to be in our standard

 

      patient information in the label, which does not

 

      have to be given to a patient.  A Med Guide would

 

      require that it be given to the patient.

 

                That does not address the issue that I

 

      have heard also from you about where does the

 

      communication between the learned intermediary and

 

      the patient occur.

 

                                                               348

 

                So, if you could think of that in three

 

      different places, there is the learned intermediary

 

      information, there is the information for the

 

      caretakers between the learned intermediary, and

 

      then there is the Med Guide where the patient gets

 

      the information whether that person has had that

 

      conversation with them or not.

 

                DR. GOODMAN:  One way of testing the

 

      confidence of this group in the efficacy, albeit

 

      unproven, of the antidepressants in the pediatric

 

      population--here I speak specifically of

 

      depression--is to go the next step, the step that

 

      the British counterpart of the FDA made.

 

                We haven't talked about that, but it

 

      certainly has been mentioned, suggested in the

 

      public hearings, or I would like to engage this

 

      group in some discussion to see if there would be a

 

      recommendation to ban the use of all the

 

      antidepressants with the exception of fluoxetine in

 

      the pediatric population.

 

                I am not saying I agree with that, but I

 

      think we should air a discussion.

 

                                                               349

 

                Dr. Nelson.

 

                DR. NELSON:  A question for FDA

 

      colleagues.  One of the presentations, it might

 

      have been Dr. Laughren might have mentioned that

 

      contraindication means different things to

 

      different regulatory agencies, and I would be

 

      curious if you could just be specific and say what

 

      does contraindication mean in Great Britain, what

 

      does contraindication mean in the United States to

 

      help answer that question.

 

                DR. LAUGHREN:  My understanding of what it

 

      means in the UK is that, in general, the drug

 

      cannot be used, but under specific circumstances,

 

      for example, by certain specialists it may be used,

 

      so it doesn't mean quite the same thing as it does

 

      in this country where if we put a contraindication

 

      in the labeling for a product, that means nobody

 

      under any circumstances should use that.  There are

 

      no circumstances where it would be appropriate to

 

      use that drug.  That is generally the way it is

 

      interpreted by clinicians.

 

                DR. GOODMAN:  Let's go with that for a

 

                                                               350

 

      moment, a discussion of whether these drugs should

 

      be contraindicated with the exception of fluoxetine

 

      in pediatric depression.

 

                Dr. Malone.

 

                DR. MALONE:  You just said it in pediatric

 

      depression.  I was going to say that two of them

 

      are already indicated in some childhood anxiety

 

      disorders, but apart from that, I would be against

 

      banning the drugs.  I think that would be a big

 

      different step.

 

                As has been said, just because studies

 

      have not proven efficacy doesn't mean that there is

 

      not efficacy, and if you failed on Prozac in

 

      depression, you wouldn't have many other options.

 

      So, I would really be against banning them.

 

                DR. GOODMAN:  Dr. Wells.

 

                DR. WELLS:  I agree with Dr. Malone, I

 

      would not favor banning the other antidepressants

 

      other than fluoxetine, because many of these

 

      children will not respond to fluoxetine, and they

 

      certainly deserve to have access to other drugs

 

      should that occur.

 

                                                               351

 

                However, I do believe that the labeling of

 

      Paxil should provide information consistent with

 

      the June 19th, 2003 FDA talk paper recommending

 

      that Paxil not be used in children and adolescents

 

      with MDD in light of the lack of proven efficacy

 

      and the troublesome documented signal for

 

      suicidality in that population.

 

                I further believe that we should recommend

 

      a similar labeling change for venlafaxine.

 

                DR. GOODMAN:  Dr. Gorman.

 

                DR. GORMAN:  I think that the black box

 

      warnings in terms of labeling makes a lot of sense

 

      especially since I think there is a way to also

 

      increase transparency to the learned

 

      intermediaries, as well as the people who use the

 

      medicine.

 

                I would strongly recommend that the Food

 

      and Drug Administration reconsider an active

 

      labeling in the pediatric section where a single

 

      sentence where it says Pediatric Usage, "After 3

 

      randomized, controlled clinical trials including

 

      600 patients, this medicine was not proven to be

 

                                                               352

 

      effective."

 

                I don't think that takes a lot of space, I

 

      don't think it's very confusing, and if you need to

 

      then reference the summary that is available for

 

      these pediatric studies at another place on your

 

      web site, I think that is perfectly appropriate.

 

                I understand that creates some other

 

      difficulties for you, but I think that if you put

 

      it in the Pediatric Use Section, it increases the

 

      transparency.

 

                So, then someone can say who wants to use

 

      Paxil, this drug has been used in 700 children in

 

      controlled trials, and it did not meet the bar the

 

      FDA said, but I think it has some potential benefit

 

      for my patient, then, they have the data to at

 

      least start to make a decision about that.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  Do you have a view on what we

 

      should do with a drug that had one positive and one

 

      negative study?

 

                DR. GORMAN:  I do.

 

                DR. TEMPLE:  That's not wise guy, I mean

 

                                                               353

 

      we are going to face that problem.

 

                DR. GORMAN:  I think you will face that

 

      problem because there is one of those drugs already

 

      there.

 

                DR. TEMPLE:  That is why I asked.

 

                DR. GORMAN:  I think you should say there

 

      has been one positive and one negative, and that

 

      doesn't meet the bar the FDA sets.  You can then

 

      argue.  Then, people will start to argue with you

 

      whether the bar is too high or too low, but I think

 

      that if you make it transparent, which is my

 

      understanding, speaking for myself and not my

 

      academy, my understanding of the intent of the Best

 

      Pharmaceutical for Children's Act, that this should

 

      make--the public is paying for these drug trials

 

      with increased consumer prices, and therefore, they

 

      have the right to the results of that data.

 

                I think that data should be reflected in

 

      the label even if it's troublesome to the Agency.

 

                DR. TEMPLE:  As I said, we are moving in

 

      that direction.  We haven't quite gotten there yet,

 

      but we have had many of the same thoughts you have

 

                                                               354

 

      expressed.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  I would strongly support what

 

      Dr. Gorman just said.  It seems to me that what we

 

      know at this point is there is a drug for which

 

      there is moderate evidence of efficacy and a whole

 

      bunch of drugs for which there isn't, but we don't

 

      really think we have good enough data on those

 

      latter drugs, both in the sense of short-term

 

      efficacy trials, and more importantly, long-term

 

      efficacy trials, and somehow or other we need to

 

      get that information out in some useful way.

 

                Second, I think we know that there are no

 

      trials for these drugs in things like migraine,

 

      headaches, minor acute depression, and other things

 

      that could be very, very risky.

 

                Third, we know something about causality,

 

      but we know causality, unfortunately, only in the

 

      SSRIs, but we have no evidence that other

 

      antidepressants have any likelihood of being less

 

      causal.

 

                DR. GOODMAN:  "Causal" with regard to

 

                                                               355

 

      suicidality?

 

                DR. PERRIN:  Suicidality.

 

                DR. GOODMAN:  It isn't just the SSRIs.

 

                DR. PERRIN:  I am sorry, the nine drugs

 

      that we are studying, my apologies.  But we don't

 

      know that it covers all antidepressants.  I think

 

      we can leave that out and say basically, we have no

 

      evidence that any other antidepressant is better or

 

      has less risk or whatever.

 

                I think finally, we should say as

 

      explicitly as we can some of the comments that Jean

 

      has raised and others have raised about the

 

      explicit elements where people should be particular

 

      vigilant about risk, the timing issues, the type of

 

      patient issues, et cetera.  I think we should be

 

      very clear about that.

 

                DR. GOODMAN:  Dr. Rudorfer.

 

                DR. RUDORFER:  I think what we are talking

 

      about is how to titrate the warning, if you will.

 

      One thought I had, we are clearly not going to be

 

      able to settle the efficacy issue today because we

 

      don't have the data before us.  Again, as was just

 

                                                               356

 

      mentioned, there are better efficacy data in the

 

      anxiety disorders than we have seen in major

 

      depression.

 

                What I am thinking is the overriding issue

 

      that we had coming in, which I think remains with

 

      us, is how to discourage irresponsible use of these

 

      antidepressants in the pediatric population

 

      while--I don't want to speak for anybody else--but

 

      my sense is that we don't want to discourage

 

      appropriate responsible use of these drugs by

 

      clinicians who are in accord with the warnings as

 

      they now exist, that is, who are monitoring

 

      patients responsibly.

 

                So, one thought I had was in terms of

 

      having a bolded section in the warning, but the

 

      bolded part would not be the adverse effect.  The

 

      bolded part would be what we want clinicians to do,

 

      that is, wording to the effect that close patient

 

      monitoring is required during use of this

 

      medication especially early in treatment and at

 

      times of dosage changes.

 

                That is just one thought off the top of my

 

                                                               357

 

      head, again directing attention to that, and I

 

      don't know if language such as required is

 

      appropriate, but something along those lines to

 

      send that message to the clinician that a higher

 

      standard of care is required with this drug, again

 

      certainly including other warning language as we

 

      have been discussing, but my point being to find

 

      the right titration where we are not scaring off

 

      appropriate use of the drugs.

 

                DR. GOODMAN:  Ms. Griffith.

 

                MS. GRIFFITH:  We are about bouncing

 

      around a bit when you raised contraindicating, the

 

      possibility of contraindication and then going back

 

      to the best methodology for informing patients and

 

      practitioners.

 

                I was compelled by the arguments both Dr.

 

      Nelson and Dr. Pine made with respect to the black

 

      box, and I am wondering if it is not now a

 

      knee-jerk reaction when a doctor sees a black box

 

      warning, as you suggested, Dr. Nelson, just to

 

      absolutely refuse to use that particular

 

      medication, and, if so, I think that that poses a

 

                                                               358

 

      hazard to the ability for a doctor, a psychiatrist

 

      hopefully, in using that drug in his or her tool

 

      box.

 

                I also, no disrespect intended to Drs.

 

      Temple and Trontell, when you said that by

 

      developing a mechanism, either informed consent or

 

      patient information letter would be burdensome, and

 

      I believe that Dr. Trontell said that the FDA does

 

      not like to get in between the patient and the

 

      provider by dictating what a provider has to do by

 

      way of informing, I think that that is wrong.  I

 

      don't think burdensome is the right way to look at

 

      this.

 

                I mean it may be burdensome, but it is

 

      absolutely necessary, and I don't think that the

 

      FDA should feel that they can't advise doctors and

 

      caregivers to be very forthcoming and very

 

      interactive with the patient, so I would recommend

 

      either a letter or--

 

                DR. GOODMAN:  Tom, you had a comment?

 

                DR. LAUGHREN:  We actually have a

 

      precedent for an informed consent in the pediatric

 

                                                               359

 

      area in child psychiatry for Cylert.  There is a

 

      consent form.  The problem is that it is voluntary,

 

      and it is not clear how much it is actually used.

 

                Maybe some of the child psychiatrists here

 

      who have used Cylert can comment on whether or not

 

      they actually use that.

 

                DR. PINE:  I can tell you that the safety

 

      issues around Cylert, when they became public, led

 

      to a dramatic decrease in the use, and I think it

 

      had more to do with the nature of the concern than

 

      the process that was used to monitor.  So, I don't

 

      know that this situation is completely analogous.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  A number of us have to leave

 

      within the hour, and Dr. Temple, I believe has now

 

      raised at least two specific questions that he

 

      wants us to I think put to a vote.  I am kind of

 

      concerned, I mean I would like to at least frame

 

      those two questions and see if we can at least

 

      accomplish that.

 

                As I heard them, what I would like to do

 

      is if we go back to the text before this one, of

 

                                                               360

 

      what we had for Question 3, and then I think you

 

      were asking us does this apply to all

 

      antidepressants, and we go around Yes/No, and then

 

      I think the second question, which is extremely

 

      important, is does some semblance of that

 

      information go into a black box.  I think in that

 

      case, it might be within that black box at least

 

      for, say, fluoxetine, within that box there is some

 

      statement of the efficacy data.

 

                I really am very, very concerned that the

 

      signal-to-noise ratio, the amount that is spent in

 

      direct-to-consumer advertising, even the patient

 

      information sheets, none of that really gets the

 

      attention it deserves.

 

                We may not agree with this data, it may

 

      not be what we wanted to find, but what we are

 

      sitting with is no--with one exception--no evidence

 

      of efficacy, and what we have is evidence of some

 

      causal relationship.

 

                As we were instructed, the evidence of a

 

      causal relationship for a warning that we want to

 

      really get across doesn't have to be beyond a

 

                                                               361

 

      reasonable doubt.  It may be beyond a reasonable

 

      doubt for efficacy, but for warning and drawing the

 

      appropriate attention and concern to this, I think

 

      we really need to put that.

 

                So, I am sort of dealing with those two

 

      questions, if we could, Mr. Chairman, frame those

 

      questions and vote on them before we go ahead.

 

                DR. GOODMAN:  Unless I suffered a stroke

 

      here, I think we already voted on the first

 

      question, Question 3, that has already been voted,

 

      and I don't think we need to have that 3(b) in

 

      there, because the implication of 3(a) is that we

 

      did not exempt any of the antidepressants, at least

 

      when we were talking in terms of the trials.

 

                I think what you are getting at is in

 

      whatever form the warnings take, should that be

 

      expanded to all the antidepressants, and although

 

      we didn't vote on that, my sense from the

 

      discussion is the answer was Yes.

 

                So, I think we have already answered that.

 

      Partly because there isn't that much time left, and

 

      I do really want to end at 5 o'clock, is unless

 

                                                               362

 

      there is a compelling reason, I do not want to

 

      subject these additional questions to a vote.

 

                The only one that I think that perhaps

 

      might merit a vote at this point is the black box,

 

      but still let me remind the committee that we are

 

      not making decisions, we are making

 

      recommendations, and it will be up to the FDA

 

      whether or not to implement that recommendation.

 

                Dr. Katz.

 

                DR. KATZ:  There is one other labeling

 

      question we either need you to take a vote on

 

      quickly or just sort of get a general sense, but

 

      that has to do with the contraindication question

 

      and whether or not the sense of the room is that

 

      they should not be or should be contraindicated.

 

                DR. GOODMAN:  I would rather start at that

 

      end.  I agree with that, and I think what I would

 

      like to do is after just a few more moments of

 

      discussion, equivalent to the British ban, we are

 

      using the word contraindication, or any other

 

      discussion before we take a vote on whether this

 

      committee would support contraindication of all the

 

                                                               363

 

      antidepressants except fluoxetine in major

 

      depression.

 

                Dr. Nelson.

 

                DR. NELSON:  My interpretation of the

 

      meaning of the two words in the two different

 

      medical systems is that contraindication in the

 

      United Kingdom is not a ban, and is simply a way of

 

      driving the use of these drugs into the hand of

 

      appropriately qualified specialists.

 

                If that interpretation is correct, then,

 

      contraindication in our system would not be the

 

      equivalent response, and if we think that that was

 

      the correct thing for them to do, the question is

 

      do we have another mechanism available to us here,

 

      such as adding a kind of oncology type warning

 

      about appropriately qualified specialists to

 

      accomplish that.

 

                In my mind, saying it should be

 

      contraindicated here is a very different meaning.

 

      It would be a ban in the United Kingdom perhaps,

 

      but contraindication there was not a ban from my

 

      interpretation of what I was told.

 

                                                               364

 

                DR. GOODMAN:  In the UK, they were banned

 

      is my understanding.

 

                Dr. Temple.

 

                DR. TEMPLE:  Well, no, there is wording

 

      that sort of suggested if you are properly trained

 

      and really need to, you can do it.  But a

 

      contraindication here, and you can safely vote on

 

      that, means we think--we think you can still do it,

 

      we don't control your pen--means we think there is

 

      no circumstance in which anybody should use these

 

      drugs for that purpose.

 

                DR. GOODMAN:  But at the peril of the

 

      prescriber.

 

                DR. TEMPLE:  The prescriber doesn't have

 

      to pay attention to our labeling, and sometimes

 

      they don't, but it would reflect the view of us,

 

      and presumably the manufacturer that writes it, the

 

      rightful labeling, that you should not use these

 

      drugs for that purpose.  There is no case in which

 

      the benefits outweigh the risks.  That is what it

 

      means.

 

                DR. GOODMAN:  More discussion on

 

                                                               365

 

      contraindication?

 

                Dr. Malone.

 

                DR. MALONE:  If you contraindicate it for

 

      major depressive disorder, is it automatically

 

      contraindicated for off-label, or what happens to

 

      all these other uses?

 

                DR. TEMPLE:  Off-label use is not

 

      discussed in labeling.  That is why it is called

 

      off-label use.  We know perfectly well that people

 

      have been using these drugs in pediatric patients

 

      even though it is not in the label.

 

                A contraindication actually would tend to

 

      discourage that use, because you are then reacting

 

      not to silence, but to a specific statement that

 

      says you really shouldn't do this.  So, it changes

 

      the present situation, there is no doubt about it.

 

                DR. GOODMAN:  Ms. Dokken.

 

                MS. DOKKEN:  Just a quick question of

 

      clarification.  What is the impact of

 

      contraindication on further research?

 

                DR. TEMPLE:  Well, further research is

 

      currently very difficult because everybody has got

 

                                                               366

 

      its exclusivity, that is the main impediment to me,

 

      further research.  I don't think a contraindication

 

      necessarily means that no one is going to bother to

 

      study it further.

 

                I don't think we have practical experience

 

      that gives that answer, and it might discourage it

 

      some.  I don't think we know.

 

                DR. KATZ:  But it doesn't legally preclude

 

      it or anything.  It can be done.

 

                DR. GOODMAN:  Dr. Leslie.

 

                DR. LESLIE:  Just in the interest of time,

 

      I would like to move that we do not accept a

 

      contraindication, but we do suggest that there be

 

      wording to such that these medications should be

 

      given by people trained in their appropriate use.

 

                I would be worried about saying

 

      subspecialist because there are a number of primary

 

      care doctors that have no access to mental health

 

      professionals in rural communities or urban

 

      Medicaid areas, and you would be doing a disservice

 

      to those populations, but if you said trained in

 

      the appropriate use, it goes back to their

 

                                                               367

 

      professional bodies to come up with appropriate

 

      continuing medical education for the use of these

 

      medications.

 

                DR. GOODMAN:  Now, we do not have to take

 

      a vote on this.  We can just continue to discuss

 

      it.

 

                DR. TEMPLE:  I just want to remind

 

      everybody that it is really hard to give

 

      instructions for use of something that isn't

 

      approved for use.  I am not saying we can't figure

 

      out a way out of it, but it is a very thorny

 

      problem and we are sort of bound by our own rules,

 

      but it kind of implies that you should use it when

 

      you tell people how to get trained for using it.

 

                DR. GOODMAN:  Dr. Marangell.

 

                DR. MARANGELL:  I like the idea of the Med

 

      Scrip [ph] where the patients get information and

 

      the family gets information.

 

                A question.  Is there a way to ban direct

 

      consumer advertising without a black box?

 

                DR. TEMPLE:  The black box doesn't ban it.

 

      You just have to incorporate the black box or its

 

                                                               368

 

      elements anyway into the label.

 

                Our conclusion was that direct-to-consumer

 

      advertising was legal, and that is why it became

 

      allowed.  There is nothing in the law against it.

 

      Therefore, under at least many interpretations of

 

      the Constitution, you are allowed to do it, and our

 

      rules.  So, I don't know if there is a way to--I

 

      don't think there is an easy way to ban it.

 

                We would not allow reminder ads.  I don't

 

      know whether that is important to anybody, but

 

      those are not allowed.

 

                DR. GOODMAN:  Let me express the Chair's

 

      view on the contraindication.  I would oppose it.

 

      If we took a vote, I would definitely oppose it.  I

 

      am repeating myself here.

 

                I would disagree that there is no data

 

      outside of fluoxetine.  There are data supporting

 

      efficacy.  They are not great data, they are not

 

      very good data, and they are very limited data.

 

      There are some negative data certainly from the

 

      clinical trials, and most of the data that we have

 

      is anecdotal experience, but it is not from one,

 

                                                               369

 

      two, or three people.  It is from a multitude of

 

      trained clinicians and patients.

 

                Now, they could have been misled.  They

 

      could have misled themselves into their being an

 

      effective drug when there was just a nonspecific

 

      effect of the therapeutic encounter or time alone.

 

                We know that, I know that, but I can't

 

      ignore, as we can't ignore some of the public

 

      testimony about instances that seemed to implicate

 

      the medications in suicide.

 

                We also can't ignore the possibility that

 

      there is data out there that we don't have in a

 

      form that we can analyze to our satisfaction that

 

      points to the effectiveness and the protective

 

      action of these drugs against suicide, particularly

 

      in the long-term treatment of depression.

 

                In the absence of those data, in the

 

      absence of, say, negative studies, I would be very

 

      reluctant to deprive patients of that opportunity.

 

      So, I am not ready at this point, given what we

 

      know, to ban the antidepressants.

 

                Other comments?  Dr. Fant.

 

                                                               370

 

                DR. FANT:  In listening to the various

 

      comments, is it reasonable to emphasize the

 

      concerns with a black box and include wording in

 

      the black box that gives the serious,

 

      knowledgeable, committed caregiver license to make

 

      choices that someone less qualified or less

 

      thoughtful would make under those conditions?

 

                I mean I think there are a number of us,

 

      when we take care of kids, institute therapies that

 

      are more risky than other situations when we are

 

      faced with limited options, but we do it

 

      thoughtfully, or at least we try to do it

 

      thoughtfully.

 

                Is there any way to sort of strike that

 

      balance with the black box and the wording?

 

                DR. GOODMAN:  Let's ask the FDA.  What

 

      kind of liberties do you have within the black box?

 

                DR. TEMPLE:  What you usually put in a

 

      black box is a warning about the adverse

 

      consequences of the use of the drug, and so you

 

      would say we know this about use in pediatric

 

      populations or whatever, and then therefore, it

 

                                                               371

 

      says therefore, you really should monitor closely,

 

      and I guess you could stick in there, therefore,

 

      you should be particularly aware of the signs of

 

      symptoms of deterioration or something like that.

 

      We could think about that.

 

                Those things are all possible.  It is a

 

      little tricky to sort of identify responsible

 

      versus non-responsible physicians like, you know,

 

      only responsible physicians, and you know who you

 

      are, should use this drug, but you can certainly

 

      say what they should be worried about and what kind

 

      of thinking they should go through.

 

                DR. GOODMAN:  Dr. Maldonado.

 

                DR. MALDONADO:  Just a quick comment on a

 

      ban or contraindication and box warnings.  There

 

      was a question about the impact in future research.

 

      I just remembered that a ban in the UK is probably

 

      not regulatorily different than a ban in the United

 

      States, is that the enforcers in the United States

 

      are lawyers, and we live in a different kind of

 

      environment.  The FDA doesn't enforce that, but

 

      companies already know that with these restrictions

 

                                                               372

 

      in the label, they are going to have tremendous

 

      liability to do any future studies.

 

                Again, the ban in the UK is a ban in the

 

      UK, but physicians may take risks in the UK that

 

      physicians in the United States may not be willing

 

      to take.

 

                DR. GOODMAN:  Thank you.

 

                Dr. Nelson.

 

                DR. NELSON:  One suggestion in terms of

 

      allowing the kind of information you need would be

 

      to have more of that information in the Pediatric

 

      Use Section, and just refer to that section out of

 

      the black box.  You want the black box to be to the

 

      point.

 

                The only other question I would ask the

 

      group is have we had enough discussion about the

 

      Med Quick or whatever the name is for the patient

 

      information to have formulated a view as to whether

 

      there would be a recommendation to develop that

 

      kind of a document, because that is one thing I

 

      heard is a need certainly from the public

 

      testimony.

 

                                                               373

 

                The label is one thing, but having it in

 

      language that could be understood, maybe physicians

 

      will then read that document, would be a useful

 

      thing.

 

                DR. GOODMAN:  Dr. Fost.

 

                DR. FOST:  I wanted to get back to that

 

      patient information thing and follow up on Dr.

 

      Rudorfer's comment, that both the message to the

 

      patient and the physician has got to include this

 

      importance of monitoring, but I haven't heard any

 

      discussion yet of what monitoring means.

 

                Does it mean seeing the patient once a

 

      week, if so, by whom?  Twice a week, once every two

 

      weeks, is it phone contact monitoring?  Does FDA

 

      get into that depth of defining terms?  The word

 

      "monitoring," to me means nothing. I mean I have no

 

      idea what it means.

 

                So, until somebody defines it for me,

 

      seeing it in a package insert doesn't tell me, as a

 

      physician, what it is I am supposed to be doing,

 

      but I have a sense that it is critical, that it is

 

      very important that the patients be monitored

 

                                                               374

 

      closely.

 

                MS. DOKKEN:  Dr. Nelson just asked about

 

      the Med Guides.  My question is they go directly to

 

      the patient from whom, the clinician or the

 

      pharmacist?

 

                DR. TEMPLE:  They are given out by the

 

      pharmacist, and they are required to be given out,

 

      but we don't think they necessarily always are, but

 

      they can be attached to the prescribing package,

 

      that is, to a unit of use package.  In quite a

 

      number of cases, we have converted drugs to unit of

 

      use packaging in part so that they would carry the

 

      Med Guide, because then they always have it.

 

                DR. TRONTELL:  I don't know if this was

 

      your point.  The patient would get the Medication

 

      Guide presumably after they have already filled the

 

      prescription.

 

                MS. DOKKEN:  So, it isn't necessarily an

 

      opportunity, sort of a planned opportunity for a

 

      conversation with the clinician.

 

                DR. TRONTELL:  If you want the patient to

 

      be informed before they actually receive the drug,

 

                                                               375

 

      you would need to be do something in addition to

 

      the Medication Guide.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  As we are not voting on

 

      these issues, I just wanted to make a few brief

 

      comments.  I would strongly support the black box,

 

      and I have to say we heard yesterday and I know we

 

      have discussed this a number of times on the

 

      Pediatric Advisory Committee, I think, for me,

 

      package inserts are a legal document between the

 

      company and the FDA, but I don't think they are

 

      read.

 

                We heard from a physician who presented

 

      yesterday afternoon that he had not read the

 

      package insert, didn't know what was in the package

 

      insert, so I think we can put whatever we want in

 

      there, but I think if you took a poll around this

 

      table, most of us do not--that is not where we get

 

      our information.

 

                So, I think anything other than that is

 

      important. I think the black box is important, I

 

      think the Web Guide or Med Guide, I think attached

 

                                                               376

 

      to the box is fabulous, but we were also discussing

 

      the possibility of having a site on the FDA

 

      internet site, which is very visible, very easily

 

      navigated for the public to discuss adverse events.

 

                Ms. Griffith and I, she was informing me

 

      about the FDA web site and how difficult it is

 

      currently to get the information on adverse events,

 

      and I think that that is another route that if you

 

      had advisories that were easily accessible, where

 

      patients could go in and get that information

 

      before or when the physician says I am going to

 

      prescribe this, but you can go back and get

 

      information.

 

                So, I would just add those comments.

 

                DR. GOODMAN:  Ms. Bronstein.

 

                MS. BRONSTEIN:  I just want to reiterate

 

      again, I think that the family and the patient must

 

      receive something.  I think having the Med Alert

 

      come with the drug itself is a good mechanism

 

      provided the information on there talks about

 

      suicidality.

 

                I think we have to be really clear about

 

                                                               377

 

      what the risks are that the patient has to call the

 

      physician about, even if the physician doesn't

 

      invite that half of the conversation.

 

                I guess I vote against the black box.  I

 

      want to be pretty specific about that.  I think we

 

      heard very clearly from family members that drugs

 

      were helpful, we heard some that were very

 

      unhelpful, but the biggest message that I heard

 

      from the consumer is they want to be warned about

 

      what the risk is.

 

                DR. GOODMAN:  So, did you say you would

 

      vote against it?

 

                MS. BRONSTEIN:  I would vote against the

 

      black box, but I would vote for the Med Alert going

 

      directly to the patient.  I think information

 

      should go to physicians on monitoring importance

 

      and frequency of visits.

 

                DR. MURPHY:  You can do both.  I just want

 

      to make it clear, one does not rule out the other.

 

                MS. BRONSTEIN:  I understand.

 

                DR. MURPHY:  I think you should look at

 

      what is in the labels right now, too, because that

 

                                                               378

 

      is the other thing. We already have bolded

 

      information in the Warning Section.

 

                MS. BRONSTEIN:  I felt the bolded

 

      information was a good beginning, but I think we

 

      need to go further.

 

                DR. GOODMAN:  Dr. Pine.  I would like us

 

      to take a vote on the black box issue.  I think we

 

      have had sufficient discussion.  It is not clear to

 

      me what the preponderance of opinion is, and I

 

      think we won't know until we go around the table.

 

                First, Dr. Pine.

 

                DR. PINE:  Two brief comments, one

 

      definitely relevant to the black box, the other

 

      indirectly relevant.

 

                One thing that we haven't talked about

 

      that relates directly to the issue of restricting

 

      access or reducing access to treatments is we

 

      didn't talk about what are the data for other

 

      available treatments for children who suffer from

 

      major depression.

 

                In some ways, some of the most disturbing

 

      or concerning findings are the data for cognitive

 

                                                               379

 

      behavioral psychotherapy from the TADS trial,

 

      because while you can debate to some degree about

 

      the magnitude of the effect of fluoxetine, I think

 

      that there has been little debate about what the

 

      study says about cognitive behavioral

 

      psychotherapy, which currently is considered the

 

      best documented effective psychotherapeutic

 

      treatment for pediatric depression.

 

                The data from the TADS trial were very

 

      clear.  That treatment was inferior to fluoxetine

 

      alone, and it was no different from placebo.  So,

 

      that is number one.

 

                Number two, I am sympathetic to the views

 

      from the FDA that, you know, saying that this is an

 

      unusual circumstance and we are not really sure

 

      what to do, and I would, again, just speaking for

 

      myself, say that I think it calls for some very

 

      careful thought about how we are going to need to

 

      think about these kinds of issues differently

 

      relative to what the current options are, because

 

      there are a couple of highly unusual things about

 

      pediatric mental illness right now, one of which is

 

                                                               380

 

      that the majority of treatment with psychotropic

 

      agents, at least to the extent that we have talked

 

      about it, is off-label use, which I think is a

 

      problem that we all agree that we can't ignore.

 

                The second is that the level of knowledge

 

      in pediatric mental illness right now, in general,

 

      is not sufficient, so that we can make very strong

 

      statements.

 

                So, I guess just in closing, to echo some

 

      of the statements from Dr. Bronstein, I, too, would

 

      not favor the black box.  I am not sure what else

 

      we need to do.  I think we need to do something

 

      clearly more than what has been done, and there

 

      might not be a current available thing to do.

 

                DR. GOODMAN:  Let me ask a question as we

 

      are trying to compose the question here.  Is the

 

      black box warning to contain information only about

 

      risk, or does it also contain an evaluation of

 

      relative benefit and risk?  If the latter is the

 

      case, then, fluoxetine would be exempt.

 

                If what we are trying to do in the black

 

      box is convey risk, then, it should be consistent

 

                                                               381

 

      with our earlier votes and apply to all

 

      antidepressants in the entire pediatric population.

 

                Dr. Katz.

 

                DR. KATZ:  I think you can do both.  I

 

      think you can say in a black box--first of all,

 

      black box is primarily for risk, but it's a

 

      warning, right, since it clearly is intended to

 

      convey a risk, but you can say this risk exists in

 

      pediatric patients, and this drug has not been

 

      shown to be effective in pediatric patients.

 

                For a drug that has been shown to be

 

      effective, you can just say here is the risk, and

 

      the drug already carries the indication in the

 

      label.  So, you can tailor what is in the black box

 

      depending upon what you know about the drug, both

 

      for risk and effectiveness, but it is primarily for

 

      risk, but you can handle that within the black box.

 

                DR. GOODMAN:  So, the black box for

 

      fluoxetine, you might have a statement in terms

 

      of--

 

                DR. KATZ:  I don't know, but you might not

 

      say anything about effectiveness although it is

 

                                                               382

 

      already in the indication.  In other drugs, you

 

      might say here is the risk and, by the way, we

 

      remind you that it has not been shown to be

 

      effective.  We can sort of play with the language.

 

                DR. GOODMAN:  In any event, it seems like

 

      this warning should be broader.  The question

 

      should apply to the pediatric population.

 

                DR. KATZ:  Right, it should not be limited

 

      to depression.

 

                DR. GOODMAN:  It is not limited to

 

      depression consistent with our earlier votes.

 

                DR. KATZ:  Right.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  Each one of us may have an

 

      opinion. Why don't we just plan then to use our 30

 

      seconds to express it relative to what should or

 

      shouldn't be in and how to link it rather than

 

      trying to agree on that before we vote.

 

                The box is fine, just in terms of what

 

      goes in it. We may have different views, and we

 

      could just then express that as we vote.

 

                DR. GOODMAN:  I agree with that.

 

                                                               383

 

                Dr. Leslie.

 

                DR. LESLIE:  I just wondered if you could

 

      summarize the advantages and disadvantages of the

 

      black box, because we have kind of gone all around

 

      it.

 

                DR. GOODMAN:  I have a volunteer.  Dr.

 

      Maldonado.

 

                DR. MALDONADO:  I think that it might

 

      actually be very good to know if the committee

 

      knows the criteria for precautions, one, in black

 

      box.  It seems that people are all over the place.

 

      I think that the FDA has criteria.  It may not be

 

      very strict, but it might be good to receive that

 

      kind of guidance before you vote.

 

                DR. GOODMAN:  Dr. Temple.

 

                DR. TEMPLE:  I wish I could remember.  We

 

      put out a draft guidance document.  Basically, a

 

      black box warning is for something you want

 

      everybody to pay attention to, and the reason you

 

      put it in a black box, it is more visible that way,

 

      and people pay attention to things that stand out.

 

                You can emphasize things by using dark

      print, too, but the black box is prominent, it's

 

      the first thing you see when you come to labeling.

 

      It is always at the top.  Then, in relative reform,

 

      and it may be expanded on later, but it is supposed

 

      to catch everybody's eye.  It shows up more or less

 

      the same way in promotion, so you see it.  That is

 

      the reason.

 

                It is used for things that matter, for

 

      things that can be fatal, and I would add it is

 

      particularly attractive where there is something

 

      you can do about it.

 

                DR. GOODMAN:  I think, in my mind, the

 

      advantages are it attracts attention, it is an

 

      attention getter.  The disadvantages, which may

 

      also be the advantages, it will discourage use, and

 

      it may have some implications for the ability of

 

      the manufacturers to promote their products, market

 

      their products, at least in some forms, which again

 

      might be, depending how you are looking at it, an

 

      advantage.

 

                We need to go to a vote.  We are going to

 

      start at this end of the table.

 

                                                               385

 

                Dr. Santana--oh, Dr. Santana is gone.

 

      Okay.

 

                Dr. O'Fallon.

 

                DR. O'FALLON:  Because people are leaving,

 

      could you ask them to vote on both the black box

 

      and the Med Guide?

 

                DR. GOODMAN:  I don't think we are going

 

      to have time to take all those votes.  We haven't

 

      finished talking about new studies.

 

                DR. TEMPLE:  We are assuming from

 

      everything that has been said that people like the

 

      idea of the Med Guide.

 

                DR. GOODMAN:  We don't need to vote for

 

      that.

 

                Dr. O'Fallon.

 

                DR. O'FALLON:  Black box, I like the idea,

 

      yes.  I vote yes.  I think the idea of having the

 

      two flavors, one for those that have been shown

 

      efficacious and those that haven't is a good idea,

 

      so I like the idea.

 

                DR. GOODMAN:  Dr. Pollock.

 

                DR. POLLOCK:  Yes, I also vote for the

 

                                                               386

 

      black box with the same comment as Dr. O'Fallon.

 

                DR. GOODMAN:  Dr. Wells.

 

                DR. WELLS:  I would vote against the black

 

      box because of my concerns that it would decrease

 

      access to many patients who need to have the

 

      medications.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  Yes, on the black box, and I

 

      guess I would like to emphasize what Ms. Bronstein

 

      said, that I think this is great for informing the

 

      physician, and the Med Guide is good for informing

 

      the patient, but it is important to have that

 

      discussion about the risks and benefits at the time

 

      the drug is being prescribed, and I don't think the

 

      black box will accomplish that.

 

                DR. GOODMAN:  Thank you.

 

                Ms. Dokken.

 

                MS. DOKKEN:  Yes, on the black box, and if

 

      we adjourn before, I also want to say I think the

 

      Med Guide is great, but it is too late and does not

 

      involve that opportunity to have a discussion

 

      between the clinician and the family and patient.

 

                                                               387

 

                DR. GOODMAN:  Irwin has departed.

 

                Marangell.

 

                DR. MARANGELL:  I am actually very torn on

 

      this issue.  I think it is essential that we get

 

      the word out.  I am very concerned about a backlash

 

      against people who really need appropriate

 

      treatment and not getting it, particularly since

 

      there is a dearth of specialists.  I will vote

 

      therefore no on the black box, but support the

 

      revised bolded warning, the Med Quest, and perhaps

 

      some additional education efforts.

 

                DR. GOODMAN:  Robinson.

 

                DR. ROBINSON:  I would vote yes in the

 

      sense that if we are really saying that there is a

 

      potentially fatal side effect that might occur in

 

      2, 3 percent of children taking these drugs, I

 

      think we have to in some way make sure that that

 

      information gets out.

 

                I am not really as concerned in some ways

 

      of black box bolding.  I just think that we need to

 

      make sure that a potentially fatal side effect with

 

      2 or 3 percent of the population needs to get out

 

                                                               388

 

      there.

 

                DR. GOODMAN:  Leslie.

 

                DR. LESLIE:  Yes, on the black box, yes,

 

      on the Med Guide, and then I also just come back to

 

      exactly what some of the other people have said,

 

      the importance, but I think this goes back to the

 

      professional bodies, and I don't know what the FDA

 

      can do to push this from bodies like the American

 

      Academy of Pediatrics, et cetera, but guidelines

 

      for informed consent, guidelines for follow up and

 

      monitoring, and then it really bothers me that the

 

      majority of education on these medications is done

 

      in CME that is funded by pharmaceutical companies,

 

      and I don't necessarily feel that it is always a

 

      fair perspective.

 

                So, I also think pushing for unbiased

 

      reporting of results and in continuing medical

 

      education.

 

                DR. GOODMAN:  Griffith.

 

                MS. GRIFFITH:  I have to say I, too, am

 

      very conflicted, and I appreciate Dr. Marangell's

 

      point of view. I have anecdotal evidence from my

 

                                                               389

 

      family background that would make me very leery of

 

      suggesting to a physician that he or she should be

 

      over the top and overly concerned to the extent

 

      that they precluded use of that drug.

 

                But on the other hand, I am convinced by

 

      the force of some of the psychiatrists who feel

 

      that this would be beneficial, so I will vote yes.

 

                DR. GOODMAN:  Dr. Chesney.

 

                DR. CHESNEY:  Yes, this is a

 

      life-threatening complication in a severe disease,

 

      and I vote yes.

 

                DR. GOODMAN:  Dr. Goodman.  My vote is

 

      yes.  It will make prescribing more difficult.  I

 

      anticipate there will be alarm from parents and the

 

      child, and I think that is worth that complication,

 

      because it will raise the threshold to prescribing

 

      and force an engagement of a discussion, not only

 

      about the risks, but the potential benefits and

 

      alternatives to medication.

 

                Dr. Rudorfer.

 

                DR. RUDORFER:  I would vote no on the

 

      black box.  I believe that while we are concerned

 

                                                               390

 

      about a 2 to 3 percent increase of risk of

 

      suicidality, I think the underlying illness carries

 

      a 15 percent risk of suicide if left untreated, and

 

      I fear that the black box would impede access to

 

      treatments, and I think the appropriate warnings

 

      could be conveyed in bolded language that would be

 

      more likely to both be appreciated by prescribers

 

      without scaring off patients and families and

 

      clinicians.

 

                DR. GOODMAN:  Bronstein.

 

                MS. BRONSTEIN:  I couldn't have said it

 

      any better, just what he said.

 

                DR. GOODMAN:  You said yes then?

 

                MS. BRONSTEIN:  No, I am saying no.

 

                DR. GOODMAN:  I am sorry, you said no.

 

                MS. BRONSTEIN:  I am saying no, and the

 

      comments that Dr. Rudorfer has just said, said

 

      exactly what I wanted to say.

 

                DR. GOODMAN:  Dr. Pine.

 

                DR. PINE:  I would also vote no, and I

 

      would echo the comments of Dr. Rudorfer and then

 

      also add that I am particularly concerned about the

 

                                                               391

 

      paucity of child psychiatrists, and I am concerned

 

      that the black box might, in particular, discourage

 

      use by primary care physicians who might have the

 

      necessary skills and might be the only physician

 

      available in certain areas, but would be dissuaded

 

      either from prescribing the agent or would force

 

      families to travel very far to try to find a child

 

      psychiatrist.

 

                DR. GOODMAN:  Gibbons.

 

                DR. GIBBONS:  I am going to vote no

 

      because I am unconvinced from the data at this

 

      point that the risk-benefit ratio is, in fact,

 

      negative.

 

                DR. GOODMAN:  Ebert.

 

                DR. EBERT:  No, on the black box warning.

 

      I also have some concerns about the nature of the

 

      warning with regards to a fine line between

 

      causality and also the cautions that would be

 

      expected to be followed.

 

                We have talked about generalizing this to

 

      all antidepressants, and while I think that should

 

      be done as far as the warnings and the cautions, I

 

                                                               392

 

      am not so comfortable with doing that with regards

 

      to causality.

 

                DR. GOODMAN:  It looks like a non-random

 

      distribution of opinions here.

 

                Tana Grady.

 

                DR. GRADY-WELIKY:  I am also going to vote

 

      no on the black box and support Drs. Marangell,

 

      Rudorfer, Pine, and Gibbons' statements.

 

                DR. GOODMAN:  Dr. Perrin.

 

                DR. PERRIN:  I am going to vote yes for

 

      the black box, take my 30 seconds just to say that

 

      I hope we will get a few moments to make some

 

      recommendations to the FDA regarding special

 

      credentialing or certification or training for

 

      people being able to prescribe any of the

 

      antidepressants for children.

 

                DR. GOODMAN:  Dr. Nelson.

 

                DR. NELSON:  I am going to vote yes on the

 

      black box, but two comments.  I think in this day

 

      and age, a lot of the information we get about

 

      drugs we pull from Palm-based databases.  What

 

      comes up first is a black box warning.  If it is

 

                                                               393

 

      not there, you don't find it, you don't see it, you

 

      will go right to dose, you will miss it entirely.

 

      So, I think that is the only way to get it out to

 

      people.

 

                The second is I would link that very

 

      clearly with a discussion of the risk and benefit

 

      under the pediatric-specific labeling data, which

 

      would allow, then, a very, you know, the sort of

 

      two-flavor approach and separating out fluoxetine

 

      from other drugs, and I would hope that

 

      practitioners who are not child psychiatrists would

 

      start fluoxetine and then get help if they needed

 

      it.  Then, the question would be would that deal

 

      with your 15 percent.  I don't know, it's an

 

      empirical question.

 

                DR. GOODMAN:  Dr. Malone.

 

                DR. MALONE:  I would vote yes on the black

 

      box, and I would also encourage that it include the

 

      efficacy data in the black box.

 

                DR. GOODMAN:  Dr. Fost.

 

                DR. FOST:  Thirty seconds, five points.

 

      Number one, high standards--

 

                                                               394

 

                DR. GOODMAN:  Your vote?  What was your

 

      vote?

 

                DR. FOST:  I am coming to it.  Can I start

 

      my 30 seconds now?  Number one, high standards of

 

      informed consent however the FDA thinks they can

 

      best be achieved.  Two, Med Guide, which is not

 

      relevant to that as we have heard.  Three, yes to

 

      the black box.  Four, high standards for

 

      monitoring, and I hope someone will explain to

 

      someone else what that means.  And, fifth, the real

 

      black box, Dr. Temple referred to a black box that

 

      heightens attention, but the real one, as

 

      previously mentioned, is the one that conceals what

 

      is going on, which is the black box of CME, and

 

      that is at the root of the inappropriate use of

 

      these drugs, and I realize the FDA has been quite

 

      powerless to do anything about that.

 

                DR. GOODMAN:  Dr. Pfeffer.

 

                DR. PFEFFER:  I vote yes for the black

 

      box, and I am also concerned that we need more

 

      information from studies, and I am just concerned

 

      that while I am voting yes, this may inhibit that. 

 

                                                               395

 

      I think that there is such variability yet in the

 

      population studies and the methodologies that the

 

      spirit of warning and the spirit of monitoring, I

 

      highly agree with.

 

                I would just hope that there would be an

 

      effort yet to study these drugs further.

 

                DR. GOODMAN:  Dr. Fant.

 

                DR. FANT:  I vote yes on the black box,

 

      and the comment I would like to make is that if

 

      careful attention is paid to the wording, I don't

 

      think the black box will have an adverse effect on

 

      access of potentially useful medications for kids,

 

      from knowledgeable, thoughtful providers who

 

      thought certain drugs may be of benefit.  I think

 

      it may have a desired effect on wise cavalier use

 

      of drugs in an unthoughtful way.

 

                DR. GOODMAN:  We have an independent

 

      accounting firm auditing the vote at this moment.

 

                I am prepared to read it.

 

                This time, we have a total of 23 votes, 15

 

      Yes, 8 No.  So, more of a split decision than we

 

      had on our previous votes.

 

                                                               396

 

                We are running nearly out of time.  I

 

      think we have covered really most of what I hoped

 

      to accomplish in No. 4.  We can't subject every

 

      recommendation to a question, I don't think we can

 

      come up with every possible recommendation here.  I

 

      think we have made tremendous progress in giving

 

      the FDA a sense of where we stand.

 

                The final Question 5, maybe just take two

 

      minutes. I think throughout, the meeting has been

 

      punctuated by discussion about what data is

 

      missing, what studies need to be done, and maybe

 

      people can add to what I omit.

 

                Certainly, we need more efficacy data.  We

 

      need safety data in which one of the intended

 

      endpoints is assessing suicidality, so it is being

 

      assessed appropriately and prospectively, and with

 

      sample sizes accordingly, which, of course, could

 

      represent some problems.

 

                Nevertheless, it needs to be done.  We

 

      need to have long-term data including comparison

 

      trials with fluoxetine, but also retaining a

 

      placebo-controlled group. There are things I could

 

                                                               397

 

      mention, but I think those are some of the main

 

      clinical trials highlights.

 

                Dr. Marangell, you want to add?

 

                DR. MARANGELL:  Any future written

 

      requests, inclusion of suicidality assessment, and

 

      consistent data dictionary.

 

                DR. GOODMAN:  Other comments on future

 

      recommendations on research?

 

                DR. O'FALLON:  Maybe even having a group

 

      that would look at suicidality events in some of

 

      these studies.

 

                DR. GOODMAN:  Dr. Newman.

 

                DR. NEWMAN:  Everyone has called for a

 

      long-term trial, and I just want to give one more

 

      reason why that is important.  I agree with Dr.

 

      Nelson, who said that there should be some actual

 

      numbers in the warnings about what the risks of the

 

      increased suicidality are, but the 2 to 3 percent,

 

      that is an 8 to 12 weeks, and there doesn't seem to

 

      be evidence that it is tapering off over time.

 

                We really need to know, you know, in a

 

      year, is it four times that, and in two years, is

 

                                                               398

 

      it eight times that, because we don't know that.

 

      It is very important that the warning go on there,

 

      but, you know, it is going to be hard to write that

 

      accurately if someone is going to be on the

 

      medicine more than three months or two months, to

 

      know what to tell them.

 

                DR. WELLS:  I would like to recommend that

 

      it would be very beneficial, I think, if sponsors

 

      were encouraged to provide additional information

 

      with regard to benefits in order to help clinicians

 

      make the assessment of benefits versus risks.

 

                Specifically, if they could provide, for

 

      instance, pharmacoeconomic benefits to include cost

 

      effectiveness information and cost minimization

 

      data, and also humanistic benefits, such as quality

 

      of life.

 

                DR. GOODMAN:  Other suggestions for future

 

      research?

 

                Dr. Perrin.

 

                DR. PERRIN:  I think there is a great deal

 

      of value in doing a much better job with respect to

 

      understanding the sample selection and sample

 

                                                               399

 

      biases, and what we know about the samples at the

 

      time of entry.  I am not sure that I know exactly

 

      what the sample ought to consist of, but we ought

 

      to know something about prior history in much more

 

      detail than we currently do.

 

                We ought to know about the issue of the

 

      likelihood of bipolar disease in these kids.  We

 

      need to know how accurately, reliably, and validly

 

      to diagnose of MDD is made in these kids, and we

 

      need to know something about the social and

 

      environmental histories that might influence both

 

      response to treatment and likeliness of adherence.

 

                I will take one other moment just to plug

 

      again, I really think that we need to find a way to

 

      make sure the people who prescribe antidepressants

 

      know what they are doing.  I am a strong proponent

 

      of the fact that we shouldn't allow anyone to

 

      prescribe just by having a physician's license.

 

                DR. GOODMAN:  Dr Gorman.

 

                DR. GORMAN:  I would like to suggest that

 

      the concern about major depressive disorder in

 

      children is one of such importance to our country

 

                                                               400

 

      that this discussion not be taking place, the study

 

      not be taken upon by a pharmaceutical company, but

 

      the National Institute of Health.

 

                I think that it should be done in a way

 

      that allows the real world application of these

 

      medicines to be studied much closer to the TAD

 

      trial than to the constraints of randomized,

 

      controlled clinical trials.

 

                DR. GOODMAN:  Dr. Pfeffer.

 

                DR. PFEFFER:  I would agree with that, but

 

      this is something I wanted to mention for a while.

 

      It is a little bit out of the box, but given

 

      funding concerns, and given the potential for

 

      partnership, I wonder if there is a feasibility to

 

      consider that drug companies do be involved in

 

      these studies and that they be involved in a way

 

      that they might be able to help with said costs to

 

      the studies with the idea that it is totally

 

      unrestricted and that, for example, NIH can be the

 

      group leading this study, with selecting the

 

      participants, designing the studies, et cetera.

 

                DR. GOODMAN:  Dr. Fant.

 

                                                               401

 

                DR. FANT:  One of the things that I have

 

      been struck with in preparing for this meeting is

 

      really understanding how little we know about how a

 

      lot of these drugs work, and just the basic

 

      pharmacology that underlines them.

 

                We know the primary process that they seem

 

      to perturb, you know, but reading through the

 

      inserts, they talk about either low or no affinity

 

      for this receptor or that receptor.  Well, low

 

      affinity can mean anything from no affinity to 25

 

      percent occupancy.

 

                I think more basic research on the basic

 

      pharmacology of these drugs, the chemistry, and

 

      having a better understanding at the

 

      pharmacogenetic level of how different patients may

 

      respond to a given drug.

 

                That involves a lot of, you know, sort of

 

      moving into the studies outside of the realm of

 

      what we have been talking about up to this point,

 

      but I think those will be important to better

 

      understand what we are seeing here and perhaps be

 

      applicable to other drugs in the future.

 

                                                               402

 

                DR. GOODMAN:  I am going to turn over the

 

      meeting now to Dr. Chesney, who, as you know, is

 

      the Chair of the Pediatric Advisory Committee.  I

 

      want to ask her help in closing this meeting.

 

                           Concluding Remarks

 

                DR. CHESNEY:  Thank you.  The good news is

 

      that I have a number of pages here of things to say

 

      that have a great historical and philosophic

 

      context.  I am going to bypass all of that and on

 

      behalf of the Pediatric Advisory Committee, just

 

      make one comment which Dr. Nelson and Dr. Fost

 

      brought to my attention.

 

                That is the importance of having children

 

      and families participate in research, well

 

      constructed, well designed research, because in

 

      most cases, the investigator has been well vetted,

 

      if you will, is well understood his or her

 

      credentials have to be reviewed.  There is very

 

      close monitoring that goes on in very well

 

      constructed and high quality studies, and we get

 

      important results, and deaths are rare in very well

 

      constructed, high quality studies.

 

                                                               403

 

                So, they wanted me to pass on that general

 

      comment.

 

                My only concluding remarks are in terms of

 

      thanks. I think we would all very much like to

 

      thank the families who took so much time to come

 

      and gave us the emotional energy that it took for

 

      them to relive their tragedies.

 

                Also, to thank the psychiatrists and the

 

      families who came and explained to us in great

 

      detail the importance of having drugs available and

 

      of the many good things that these drugs have done.

 

                I particularly wanted to thank the members

 

      of the FDA who have come under such intense

 

      scrutiny over the last year, but have maintained

 

      their professionalism and their integrity, and that

 

      has meant a great deal to all of us.

 

                I also want to thank all of the members of

 

      the FDA who have organized and executed this

 

      meeting over the last two days, which has taken

 

      just an awesome effort in terms of getting the

 

      materials out to us, getting the materials out to

 

      everybody else, and having us here in a very calm,

 

                                                               404

 

      controlled, and extremely thoughtful environment.

 

                This has been a very intense two days, and

 

      I wanted to thank all of them.

 

                Finally, just to thank Dr. Rudorfer, who

 

      chaired the February session, and Dr. Goodman, who

 

      chaired this session, and Anuja Patel, who has

 

      brought it all together.  I think they have just

 

      done a fabulous job of keeping us on track.

 

                DR. GOODMAN:  Hear, hear.  I don't have

 

      much to add.  I echo all the comments of my

 

      colleague.  I also want to specifically thank the

 

      members of the Psychopharmacologic Advisory

 

      Committee and, once again, Anuja Patel.  It would

 

      be useful if you could be at my side always, make

 

      me look as good as you did during this meeting,

 

      keeping me organized.

 

                It has been a very challenging two days.

 

      I think we have made a tremendous amount of

 

      progress.  I anticipate that there could be more

 

      meetings like this, and hopefully, the next time,

 

      if we are asked to meet, it is after the emergence

 

      of additional data, particularly on the side of

 

                                                               405

 

      efficacy.

 

                We didn't take a vote on the banning.  I

 

      felt, in part, that I knew how it was going to turn

 

      out.  We were not going to vote in favor of

 

      banning.  On the other hand, I think the reason

 

      behind that was going to be based mostly on

 

      subjective experience, not so much the data at

 

      hand.  So, I didn't subject it to a vote.

 

                At some point, I would like to be in the

 

      position where, like we did on some of the other

 

      issues, is to have sufficient data before us that

 

      we could make an informed decision and make hard

 

      choices.

 

                Right now, we are in a position where the

 

      drugs are out, they are being used.  There is a

 

      widespread opinion that they not only help, but

 

      they actually save lives, but we can't really, with

 

      the data available to us, make the kind of informed

 

      decision that I think would make us all feel

 

      comfortable.

 

                I think some of the problems that have

 

      emerged, the suicide signal and the way it

 

                                                               406

 

      appeared, are a symptom of some disparities between

 

      our clinical practice and our clinical research

 

      knowledge, and I hope that, over time, that gap can

 

      be narrowed, so that our research keeps pace with

 

      the clinical needs and the clinical practice that

 

      is out there.

 

                I don't know how to suggest a mechanism to

 

      do that, and I think we have done a good deal of

 

      damage control, and I think it is unfortunate that

 

      we didn't have an opportunity to intercede sooner.

 

                With that, again, I just want to thank

 

      everybody for the participation, their attention.

 

      This has been a really outstanding meeting from my

 

      perspective, a terrific group of panel members who

 

      have grappled with very difficult decisions, and

 

      have made my job a great deal easier.

 

                Thank you again.  This meeting is

 

      adjourned.

 

                [Whereupon, at 5:00 p.m. the proceedings

 

      concluded.]
