PURPOSE

Recent advances in cancer biology, molecular biology, combinatorial chemistry, 
and screening technology provide unprecedented opportunities for discovery of 
new agents for the treatment and prevention of cancer.  Drug discovery can now 
be focused on specific molecular or regulatory sites within the cancer cell. 
The National Cancer Institute (NCI) considers exploitation of this knowledge 
and technology for discovery of new cancer therapies a high priority 
(http://plan.cancer.gov/).  It is expected that research focused on discovery 
and validation of new targets and screening design efforts to identify agents 
that affect these targets will result in a multitude of new chemical and 
biological agents with potential for clinical benefit.  However, before such 
agents can be tested and used widely in patients, safety and acceptable 
toxicity to critical organs must be demonstrated.  Current practices and 
procedures for safety evaluations are costly and time consuming utilizing 
large amounts of compound and animals.  Thus, it is impractical to evaluate 
large number of compounds, as well as analogs in a chemical series, identified 
from new high throughput molecular target based screening models.

This PA encourages the development, standardization, and validation of new and 
innovative assays which determine or predict specific organ toxicities (e.g., 
hematotoxicity, cardiotoxicity, gastrointestinal toxicity, hepatotoxicity, 
nephrotoxicity, ototoxicity, bladder toxicity, neurotoxicity, pulmonary 
toxicity, and endocrine toxicity, including pancreatic beta cell toxicity) as 
well as new methodology for high throughput toxicity screening which involves 
the use of molecular endpoints, computer modeling, proteomics and genomics.  
The development of these toxicity assays and their incorporation early in the 
development process would assist in the evaluation and prediction of human 
sensitivity and allow for more cost efficient evaluations of numerous analogs 
prior to selection of the ultimate drug development candidate. 

Through a separate PA, PA-02-075 (http://grants.nih.gov/grants/guide/pa-
files/PA-02-075.html), the NCI is inviting applications for Small Business 
Innovation Research (SBIR) and Small Business Technology Transfer (STTR) 
support, focusing on the same research areas as described in the RESEARCH 
OBJECTIVES section of this solicitation.  This PA is co-sponsored by the 
National Institute on Deafness and Other Communication Disorders, the National 
Institute of Diabetes, Digestive and Kidney Diseases, the National Institute 
on Drug Abuse, and the National Institute of Environmental Health Sciences.  
Qualified applicants are strongly encouraged to consider responding to the 
SBIR/STTR program announcement.  SBIR and STTR application information is 
available at the following website: 
http://grants.nih.gov/grants/funding/sbir.htm.  

Potential applicants who believe that they may be eligible for the SBIR/STTR 
program should contact the NCI staff listed under INQUIRIES to discuss this 
issue.  In addition, potential applicants are encouraged to access the PHS 
SBIR and STTR OMNIBUS SOLICITATION for information on eligibility requirements 
at the following website:

RESEARCH OBJECTIVES

Background

Recent advances in all branches of medical sciences provide new insight into 
the underlying mechanisms in malignancy and suggest new targets and approaches 
to therapy.  Drug discovery can now be focused on targeting key regulatory 
pathways or specific macromolecules relevant to cancer.  For example, key 
growth regulatory pathways and genes mutated in cancer cells are being 
identified, and array technology for expression of thousands of genes as well 
as computer-assisted evaluation of data are available.  New technologies in 
chemistry that allow facile synthesis of millions of new chemicals, and high 
resolution structures of important target proteins are becoming available.  
These advances taken together and coupled with high throughput screening allow 
identification of large numbers of agents that could be seriously considered 
for clinical evaluation.  Translation of these new technological discoveries 
and innovations into clinical benefit for the cancer patient through these 
newly discovered agents is essential; however, the later stages in this drug 
development process are lengthy and costly.  Obviously new procedures are 
necessary to decide which of the multitude of new agents should be tested in 
animals and then in humans.  In addition, these scientific advances can be 
extremely useful for the development of new toxicity models with novel 
endpoints to determine  therapeutic agent toxicity.

Investigations focusing on the toxicity of potential cancer, AIDS or other 
drugs or biologicals to healthy organs in intact experimental animals are the 
final steps in the preclinical stages of new drug development.  Data generated 
from these studies on each new drug are evaluated in light of potential human 
toxicity and form a major portion of the information required by the Food and 
Drug Administration (FDA) for an Investigational New Drug (IND) application.  
Preclinical toxicology studies are generally conducted in two animal species 
with the following objectives: to define the Maximum Tolerated Dose (MTD), 
Dose Limiting Toxicities (DLTs), schedule-dependency of toxicity, 
reversibility of adverse effects, and a safe clinical Starting Dose (SD).  The 
animal studies required to obtain such information for an IND application have 
significant limitations, both in terms of cost and time requirements as well 
as prediction of problems to be encountered when agents are administered to 
humans.  For example, since animal studies are very expensive and time-
consuming, it is generally impractical to evaluate numerous analogs of a 
chemical series or large numbers of possible candidates from a high throughput 
screening program.  Another concern is the lack of information gained from 
animal toxicology studies in regard to molecular mechanisms for observed 
toxicities.  It cannot be determined if toxicities of new agents designed to 
attack a key molecular target are related to actions of inhibition of that 
target or to other unknown aspects of the drug's action in various organs.

New technology to improve toxicology approaches and define toxicity at the 
molecular level are emerging, but as yet none has been validated and accepted 
for common use.  New technology will be highly valuable when combined with 
other approaches to develop a total toxicological profile of specific organ 
toxicity and molecular mechanisms responsible for this toxicity.  Data 
analysis software programs are being written to predict toxicological 
endpoints.  Individually, these activities may not be sufficient, but they may 
be highly valuable when combined with other approaches to develop a total 
toxicological profile of specific organ toxicity and molecular mechanisms 
responsible for this toxicity.

Objectives and Scope

The goals of this PA are the discovery, development and validation of new 
assays and procedures to determine quickly and cheaply toxicological profiles 
of potential therapeutic drugs.  It is expected that a molecular definition of 
toxicity in the affected organ, tissue or cell would be a component of the 
procedure.  Approaches for new toxicology assays in response to this 
initiative are broad and are determined by the creativity of the applicant.  
Genetically modified animals or cell lines, various non-mammalian organisms, 
in vitro assays utilizing primary mammalian cells (human cells are of 
particular interest), tissue slices, isolated organs, sub-cellular fractions 
or purified enzymes could be utilized for the model.  Computer modeling 
utilizing existing biological and toxicological data bases would be 
appropriate.  Genomic and proteomic technology could be exploited to profile 
total gene activity or protein expression and thereby establish molecular 
correlations with specific toxicities.  Molecular endpoints to evaluate 
toxicity and high throughput toxicity screening could be used to help decide 
which agent of a chemical series should be pursued, to allow exploration of 
toxicity at an earlier stage in drug development, to define the toxicity 
profile of agents selected for clinical trial or to define the toxicity 
profile of agents selected for clinical trial.

The NCI, through the Developmental Therapeutics Program:  
http://dtp.nci.nih.gov/, on occasion utilizes its internal resources to foster 
drug development.  For this PA, drugs and toxicology data from previous drug 
development sponsored by NCI may be made available to awardees.  For 
additional information contact Dr. Adaline C. Smith at the address listed 
under INQUIRIES.

MECHANISMS OF SUPPORT 

This PA will use the NIH R21, R33, and the combined R21/R33 Phased-Innovation 
Award mechanisms.  Applicants will be solely responsible for planning, 
directing, and executing the proposed project.  

For R21 submissions only, use the modular format (see 
http://grants.nih.gov/grants/funding/modular/modular.htm).  For combined 
R21/R33 applications, and for R33 only applications, follow the instructions 
for non-modular research applications.

For R21 submissions (when submitted without an R33 application), you may 
request up to $100,000 direct costs (four budget modules) per year unless your 
application includes consortium costs, in which case the limit is $125,000 
direct costs (five budget modules) per year.  Total project period for an R21 
application may not exceed two years.  

Specific features of the Phased-Innovation Award mechanism include:

o  Single submission and evaluation of both the R21 and R33 as one 
application.
o  Expedited transition from feasibility phase to development phase.
o  Flexible budgets.
o  Flexible staging of feasibility and development phases.

The use of multiple award mechanisms will allow projects to be submitted at 
various stages of development.  The R21 will provide support for projects in 
early stages of development where little or no preliminary data are available, 
and it is difficult to predict success sufficiently to develop an extended R33 
phase.  The R33 will provide support for projects in which feasibility has 
been demonstrated and thus are ready for extended development.  The combined 
R21/R33 will provide support for projects that require feasibility 
demonstration and for which success of aims and milestones in the R21 
component are sufficiently predictable to consider the extended R33 phase.

Under this PA, applicants can submit either an R21, a combined R21/R33, or an 
R33 application alone if feasibility can be documented, as described in the 
APPLICATION PROCEDURES section of this PA.  The total project period for an 
application submitted in response to this PA may not exceed the following 
duration: R21, 2 years; R33, 3 years; combined R21/R33 application, 4 years.  
In the combined application the R21 phase cannot extend beyond 2 years.

The R21 phase, as part of a combined R21/R33 application, may not exceed 
$100,000 direct costs per year except to accommodate indirect costs to 
subcontracts to the projects.  Although the R33 application has no official 
budgetary limit, applications requesting in excess of $500,000 dollars direct 
costs in any single year of the grant period require prior approval before 
submission.  It is strongly recommended that applicants contact NCI staff at 
an early stage of application development to convey critical information, such 
as potentially large budget requests or to discuss programmatic adherence to 
the guidelines of the proposed project.  Refer to the INQUIRIES sections of 
this PA for NCI staff contacts.

The combined R21/R33 application offers two advantages over the regular 
application process:

1.  Single submission and evaluation of both the R21 and the R33 as one 
application.
2.  Minimal or no funding gap between R21 and R33.  The award of R33 funds 
will be based on program priorities, on the availability of funds, and on 
successful completion of negotiated scientific milestones as determined by NCI 
staff in the context of peer review recommendations.

To be eligible for the Phased Innovation Award, the R21 phase must include 
well defined, quantifiable milestones that will be used to judge the success 
of the proposed research, as well as a credible plan for the development of 
technology for the R33 phase.  The Phased Innovation Award must have a section 
labeled Milestones at the end of the Research Plan for the R21 phase.  This 
section must include well-defined quantifiable milestones for completion of 
the R21 part of the application, and a discussion of the implications of 
successful completion of these milestones for the proposed R33 study.

ELIGIBLE INSTITUTIONS 

Application(s) may be submitted if the institution has any of the following 
characteristics: 

o For-profit or non-profit organizations 
o Public or private institutions, such as universities, colleges, hospitals, 
and laboratories

http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-004.html. 

I.  SPECIFIC INSTRUCTIONS FOR PREPARING THE COMBINED R21/R33 PHASED INNOVATION 
AWARD APPLICATION:

R21/R33 applications must include specific aims that are relevant to each 
phase as well as feasibility milestones that would justify transition to the 
R33 phase.  Applications must include a specific section labeled Milestones 
following the Research Plan of the R21 phase.  Milestones should be well 
described, quantifiable and scientifically justified and not be simply a 
restatement of the R21 specific aims. A discussion of the milestones relative 
to demonstration of R21 progress, as well as the implications of successful 
completion of the milestones for the R33 phase, should be included.  This 
section should be indicated in the Table of Contents.  Applications lacking 
this information, as determined by NCI program staff, will be returned to the 
applicant without review.  For funded applications, completion of the R21 
milestones will elicit an NCI expedited review that will determine whether or 
not the R33 should be awarded.  The release of R33 funds will be based on 
successful completion of negotiated scientific milestones, program priorities, 
and on the availability of funds.  The expedited review may result in 
additional negotiations of award.

R21/R33 Phased-Innovation Award application must be submitted as one 
application with one Face Page.  Although it is submitted as a single 
application, it should be clearly organized into two phases.  To accomplish a 
clear distinction between the two phases, applicants are directed to complete 
Sections a-d of the Research Plan twice: one write-up of Sections a-d and 
milestones for the R21 phase and Sections a-d again for the R33 phase.  The 
Form 398 Table of Contents should be modified to show Sections a-d for each 
phase as well as the milestones.  There is a page limit of 25 pages for the 
composite a-d text.  (i.e., Section a-d and milestones for the R21 and Section 
a-d for the R33 phase must be contained within the 25 page limit.)

In preparing the R21/R33 application, investigators should consider the fact 
that applications will be assigned a single priority score.  In addition, as 
discussed in the REVIEW CONSIDERATIONS section, the initial review panel has 
the option of recommending only the R21 phase for support.  However, a Phased-
Innovation Award application with an R33 Phase that is so deficient in merit 
that it is not recommended for support will reflect upon the judgment of the 
applicant.  For these reasons, the clarity and completeness of the R21/R33 
application with regard to feasibility milestones and specific goals for each 
phase are critical. The presentation of milestones that are not sufficiently 
scientifically rigorous to be valid for assessing progress in the R21 phase 
will reflect upon the scientific judgment of the applicant.

1.  FACE PAGE OF THE APPLICATION:
Item 2.  Check the box marked "YES" and type the NUMBER AND TITLE of this PA.  
Also, indicate that the application is submitted as an R21/R33.

Item 7a, DIRECT COSTS REQUESTED FOR INITIAL PERIOD OF SUPPORT:
For the R21 phase of the combined R21/R33 application, direct costs are 
limited to a maximum of $100,000 per year for up to two years and the award 
may not be used to supplement an ongoing project.  The requested budgets can 
exceed this cap to accommodate indirect costs to subcontracts to the project.  
Insert the total costs requested for first year of support in item 7a. 

Item 8a, DIRECT COSTS REQUESTED FOR PROPOSED PERIOD OF SUPPORT:
For the R21 phase, direct costs requested for the proposed period may not 
exceed $200,000 for two years of support.  The requested budgets can exceed 
this cap to accommodate indirect costs to subcontracts to the project.  Insert 
sum of all years of requested support in item 8a.

2.  PAGE 2 - DESCRIPTION:
As part of the description, identify concisely the technology or assay 
methodology to be developed, its innovative nature, its relationship to 
presently available capabilities, and its expected impact on toxicology 
approaches.

3.  BUDGET:
The application should provide a DETAILED BUDGET for Initial Budget Period 
(form page 4), for each of the initial years of the R21 and R33 phases as well 
as a budget for the entire proposed period of support (form page 5).  Form 
pages should indicate which years are R21 and R33.  All budgets should include 
a justification for each item requested.

4.  RESEARCH PLAN:
Item a, Specific Aims:
The applicants must present specific aims that the applicant considers to be 
scientifically appropriate for the relevant phases of the project.  The 
instructions in the PHS 398 booklet for this section of research grant 
applications suggest that the applicant state the hypotheses to be tested. 
Since the goal of this PA is to develop new methods for toxicological 
analysis, hypothesis testing per se may not be the driving force in developing 
such a proposal and, therefore, may not be applicable.  Furthermore, for R21 
grant applications, preliminary data are not required, although scientifically 
sound preliminary data should be included when available.

Item b, Background and Significance:
The applicant should elaborate on the innovative nature of the proposed 
research. Clarify how the assay or technology development proposed in this 
project is a significant improvement over existing approaches. Explain the 
potential of the proposed technology for having a broad impact on cancer 
research and toxicological evaluations.  Clearly identify how the project, if 
successful, would result in new capabilities for toxicology analysis, the 
immediacy of the opportunity, and how the proposed assays would differ from 
existing approaches.

Item c, Preliminary studies/Progress report:
The R21 phase should provide current thinking or evidence in the field to 
substantiate feasibility of the R21 phase.  While preliminary data are not 
required for the R21 phase, easily understandable data that provide relevant 
information to aid review could be included when available. The R33 phase need 
not repeat information already provided in the R21 phase.  

Applicants are encouraged to include all information required for adequate 
review evaluation.  However, in the event that assays and technology are not 
yet patent protected and the applicant does not wish to include complete 
details, the application should at a minimum provide a demonstration (results) 
of the capabilities of the proposed approach.

Item d, Research Design and Methods:
Instructions for PHS 398 should be followed.  In addition, for the R21 phase 
only, the following information must be included as a final section of Item d:

Applications must include a specific section labeled Milestones following the 
Research Design and Methods of the R21 phase.  Milestones should be well 
described, quantifiable, and scientifically justified and not be simply a 
restatement of the specific aims.  A discussion of the milestones relative to 
the success of the R21 phase, as well as implications of successful completion 
of the milestones for the R33 phase should be provided.  The page number of 
the Milestones section should be listed in the Table of Contents.  
Applications lacking this information, as determined by program staff, will be 
returned to the applicant without review.  Completion of the R21 milestones 
will elicit an expedited review by NCI program staff that will determine 
whether or not the R33 should be awarded.  The release of R33 funds will be 
based on successful completion of milestones, program priorities, and on 
availability of funds.  Expedited review may result in additional negotiations 
of award.

II. SPECIFIC INSTRUCTIONS FOR SUBMISSION OF THE R21 APPLICATION WHEN SUBMITTED 
WITHOUT THE R33 PHASE:

MODULAR GRANT APPLICATION:

R21 only applications must be submitted in a modular grant format.  The total 
project period for an R21 application may not exceed two years.  The modular 
grant format simplifies the preparation of the budget in these applications by 
limiting the level of budgetary detail.  Applicants request direct costs in 
$25,000 modules.  Section C of the research grant application instructions for 
the PHS 398 (rev. 5/2001) at 
http://grants.nih.gov/grants/funding/phs398/phs398.html includes step-by-step 
guidance for preparing modular grants.  Additional information on modular 
grants is available at 
http://grants.nih.gov/grants/funding/modular/modular.htm.

research.  Clarify how the assay or technology development in this project is 
a significant improvement over existing approaches.  Explain the potential of 
the proposed technology for having a broad impact on cancer research and 
toxicological evaluations.  Clearly identify how the project, if successful, 
would result in new capabilities for toxicology analysis, the immediacy of the 
opportunity, and how the proposed assays would differ from existing 
approaches.

Item c, Preliminary studies/Progress report:
R21 applications should provide current thinking or evidence in the field to 
support the project.  While preliminary data are not required, easily 
understandable data that provide relevant information to aid review could be 
included when available.  

Applicants are encouraged to include all information required for adequate 
review evaluation.  However, in the event that assays and technology are not 
yet patent protected and the applicant does not wish to include complete 
details, the application should at a minimum provide a demonstration (results) 
of the capabilities of the proposed approach.  

Item d, Research Design and Methods:
Instructions for PHS 398 should be followed.

III.  SPECIFIC INSTRUCTIONS FOR PREPARATION OF THE R33 APPLICATION WHEN 
SUBMITTED WITHOUT THE R21 PHASE:

The PHS 398 research and grant application instructions and forms (rev. 
5/2001) at http://grants.nih.gov/grants/funding/phs398/phs398.html are to be

approaches.

3.  BUDGET:
The application should provide a DETAILED BUDGET for the Initial Budget Period 
(form page 4) as well as a budget for the entire proposed period of support 
(form page 5).  Budget should include a justification of all items requested.

4.  RESEARCH PLAN:  
Item a, Specific Aims: Instructions in the PHS 398 booklet suggest that the 
applicant state the hypothesis to be tested.  Since the goal of this PA is to 
develop new methods for toxicolgical analysis, hypothesis testing per se may 
not be the driving force in developing such a proposal and therefore, may not 
be applicable.

Item b, Background and Significance:
The applicant should elaborate on the innovative nature of the proposed 
research.  Clarify how the assay or technology development proposed in a 
significant improvement over existing approaches.  Explain the potential of 
the proposed technology for having a broad impact on cancer research and 
toxicological evaluations.  Clearly identify how the project, if successful, 
would result in new capabilities for toxicology analysis, the immediacy of the 
opportunity, and how the proposed assays would differ from existing 
approaches.

Item c, Preliminary studies/Progress Report: 
R33 applications should clearly state how feasibility for the project has 
already been demonstrated.  It would be expected that this demonstration would 
include significant data.  This section must document that progress has been 
achieved which is essentially equivalent to that expected from an R21 grant.  
The application must clearly describe how the project is ready for scale up to 
an expanded development stage.

Item d, Research Design and Methods:
Instructions for PHS 398 should be followed.

IV.  FOR ALL APPLICATIONS:
Appendix: All instructions in the Form 398 kit apply.

APPLICATION PROCESSING: Applications must be received by or mailed before the 
receipt dates described at 
http://grants.nih.gov/grants/funding/submissionschedule.htm.  The CSR will not 
accept any application in response to this PA that is essentially the same as 
one currently pending initial review unless the applicant withdraws the 
pending application.  The CSR will not accept any application that is 
essentially the same as one already reviewed.  This does not preclude the 
submission of a substantial revision of an application already reviewed, but 
such application must include an Introduction addressing the previous 
critique.

PEER REVIEW PROCESS

Upon receipt, applications will be reviewed for completeness by the CSR and 
for adherence to the guidelines of this PA by the NCI program staff.  
Applications not adhering to the guidelines of this PA, and those applications 
that are incomplete as determined by CSR or by NCI program staff, will be 
returned to the applicant without review.

Applications that are complete and adhere to the guidelines of this PA will be 
evaluated for scientific and technical merit by an appropriate peer review 
group convened by the Division of Extramural Activities of the NCI in 
accordance with the review criteria stated below.

As part of the initial merit review, all applications will:

o  Receive a written critique
o  Undergo a selection process in which only those applications deemed to have 
the highest scientific merit, generally the top half of applications under 
review, will be discussed and assigned a priority score
o  In addition, applications receiving a priority score will undergo a second 
level review by National Cancer Advisory Board.

REVIEW CRITERIA

The goals of NIH-supported research are to advance our understanding of 
biological systems, improve the control of disease, and enhance health. The 
goals of NIH-supported research are to advance our understanding of biological 
systems, improve the control of disease, and enhance health.  Within this 
framework, the specific goals of the PA are the discovery and validation of 
new and innovative assays to predict specific toxicities of potential cancer 
drugs.  Assays developed under this PA would be expected to be effective for a 
quick and cost effective determination of toxicity of specific compounds and, 
importantly, to reduce the number of animals required. The reviewers will 
comment on the following aspects of the application in their written critiques 
in order to judge the likelihood that the proposed research will have a 
substantial impact on the pursuit of these goals.  Each of these criteria will 
be addressed and considered by the reviewers in assigning the overall score, 
weighting them as appropriate for each application.  Note that the application 
does not need to be strong in all categories to be judged likely to have a 
major scientific impact and thus deserve a high priority score.  For example, 
an important research effort may be proposed which does not present novel and 
innovative technology but which is essential to move the field forward or 
develop an innovative model. In the written comments, reviewers will be asked 
to discuss the following aspects of the application in order to judge the 
likelihood that the proposed research will have a substantial impact on the 
pursuit of these goals: 

o Significance 
o Approach 
o Milestones
o Innovation
o Investigator
o Environment
  
(1) SIGNIFICANCE:  
Does the study address an important problem? If the aims of the application 
are achieved, how do they advance scientific knowledge?  What will be the 
effect of these studies on the concepts or methods that drive this field?  
What may be the anticipated societal benefit of the proposed activity?  Will 
the proposed toxicology methodology have a competitive advantage over existing 
toxicology procedures?

(2) APPROACH:  
Are the conceptual framework, design, methods, and analyses adequately 
developed, well integrated, and appropriate to the aims of the project?  Does 
the applicant acknowledge potential problem areas and consider alternative 
tactics?  What is the time frame for developing the proposed technologies and 
suitability of this time frame for meeting the scientific community's needs?   
What are the throughput and cost effectiveness of the proposed toxicology 
assays?

(3) MILESTONES: 
How appropriate are the proposed milestones against which to evaluate the 
demonstration of feasibility for transition to the R33 development phase?  

(4) INNOVATION:  
Does the project employ novel concepts, approaches or methods? Are the aims 
original and innovative?  Does the project challenge existing paradigms or 
develop new methodologies or technologies?

(5) INVESTIGATOR: 
Are the researchers appropriately trained and well suited to carry out this 
work?  Is the work proposed appropriate to the experience level of the 
principal investigator and to that of other researchers, including consultants 
and collaborators (if any)?

(6) ENVIRONMENT:  
Does the scientific environment in which the work will be done contribute to 
the probability of success?  Do the proposed experiments take advantage of 
unique features of the scientific environment or employ useful collaborative 
arrangements?  Is there evidence of institutional support?

ADDITIONAL REVIEW CRITERIA:  In addition to the above criteria, the 
application will also be reviewed with respect to the following:

PROTECTIONS:  
The adequacy of the proposed protection for humans, animals, or the 
environment, to the extent they may be adversely affected by the project 
proposed in the application.

INCLUSION:  
The adequacy of plans to include subjects from both genders, racial and ethnic 
groups (and subgroups), and children as appropriate for the scientific goals 
of the research.  Plans for the recruitment and retention of subjects will 
also be evaluated. (See Inclusion Criteria included in the section on Federal 
Citations, below)

BUDGET:  
The reasonableness of the proposed budget and the requested period of support 
in relation to the proposed research.

For the R21/R33 Application, the initial review group will evaluate the 
specific goals for each phase and the feasibility milestones that would 
justify expansion to the R33 phase. A single priority score will be assigned 
to each scored application.  As with any grant application, the initial review 
group has the option of recommending support for a shorter duration than that 
requested by the applicant and basing the final merit rating on the 
recommended portion of the application.  For the R21/R33 application, this may 
result in a recommendation that only the R21 phase be supported, based on 
concerns related to the application's specific goals and the feasibility 
milestones justifying expansion to the R33 phase.  Deletion of the R33 phase 
by the review panel or presentation of inadequate milestones in the 
application may affect the merit rating of the application.

AWARD CRITERIA

Applications submitted in response to a PA will compete for available funds 
with all other recommended applications.  The following will be considered in 
making funding decisions:  

o  Scientific merit of the proposed project as determined by peer review
o  Availability of funds 
o  Relevance to program priorities

REQUIRED FEDERAL CITATIONS 

MONITORING PLAN AND DATA SAFETY AND MONITORING BOARD: Research components 
involving Phase I and II clinical trials must include provisions for 
assessment of patient eligibility and status, rigorous data management, 
quality assurance, and auditing procedures.  In addition, it is NIH policy 
that all clinical trials require data and safety monitoring, with the method 
and degree of monitoring being commensurate with the risks (NIH Policy for 
Data Safety and Monitoring, NIH Guide for Grants and Contracts, June 12, 1998: 
http://grants.nih.gov/grants/guide/notice-files/not98-084.html).  

Clinical trials supported or performed by NCI require special considerations.  
The method and degree of monitoring should be commensurate with the degree of 
risk involved in participation and the size and complexity of the clinical 
trial.  Monitoring exists on a continuum from monitoring by the principal 
investigator/project manager or NCI program staff or a Data and Safety 
Monitoring Board (DSMB).  These monitoring activities are distinct from the 
requirement for study review and approval by an Institutional review Board 
(IRB).  For details about the Policy for the NCI for Data and Safety 
Monitoring of Clinical trials see: 
http://deainfo.nci.nih.gov/grantspolicies/datasafety.htm.  For Phase I and II 
clinical trials, investigators must submit a general description of the data 
and safety monitoring plan as part of the research application.  See NIH Guide 
Notice on "Further Guidance on a Data and Safety Monitoring for Phase I and II 
Trials" for additional information: http://grants.nih.gov/grants/guide/notice-
files/NOT-OD-00-038.html.  Information concerning essential elements of data 
safety monitoring plans for clinical trials funded by the NCI is available:  
http://www.cancer.gov/clinical_trials/

INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH: It is the policy of 
the NIH that women and members of minority groups and their sub-populations 
must be included in all NIH-supported clinical research projects unless a 
clear and compelling justification is provided indicating that inclusion is 
inappropriate with respect to the health of the subjects or the purpose of the 
research. This policy results from the NIH Revitalization Act of 1993 (Section 
492B of Public Law 103-43).

All investigators proposing clinical research should read the AMENDMENT "NIH 
Guidelines for Inclusion of Women and Minorities as Subjects in Clinical 
Research - Amended, October, 2001," published in the NIH Guide for Grants and 
Contracts on October 9, 2001 (http://grants.nih.gov/grants/guide/notice-
files/NOT-OD-02-001.html); a complete copy of the updated Guidelines are 
available at 
http://grants.nih.gov/grants/funding/women_min/guidelines_amended_10_2001.htm
. The amended policy incorporates: the use of an NIH definition of 
clinical research; updated racial and ethnic categories in compliance with the 
new OMB standards; clarification of language governing NIH-defined Phase III 
clinical trials consistent with the new PHS Form 398; and updated roles and 
responsibilities of NIH staff and the extramural community.  The policy 
continues to require for all NIH-defined Phase III clinical trials that: a) 
all applications or proposals and/or protocols must provide a description of 
plans to conduct analyses, as appropriate, to address differences by 
sex/gender and/or racial/ethnic groups, including subgroups if applicable; and 
b) investigators must report annual accrual and progress in conducting 
analyses, as appropriate, by sex/gender and/or racial/ethnic group 
differences.

INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS:  
The NIH maintains a policy that children (i.e., individuals under the age of 
21) must be included in all human subjects research, conducted or supported by 
the NIH, unless there are scientific and ethical reasons not to include them. 
This policy applies to all initial (Type 1) applications submitted for receipt 
dates after October 1, 1998.

All investigators proposing research involving human subjects should read the 
"NIH Policy and Guidelines" on the inclusion of children as participants in 
research involving human subjects that is available at 
http://grants.nih.gov/grants/funding/children/children.htm. 

REQUIRED EDUCATION ON THE PROTECTION OF HUMAN SUBJECT PARTICIPANTS:  NIH 
policy requires education on the protection of human subject participants for 
all investigators submitting NIH proposals for research involving human 
subjects.  You will find this policy announcement in the NIH Guide for Grants 
and Contracts Announcement, dated June 5, 2000, at 
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html.  A 
continuing education program in the protection of human participants in 
research in now available online at: http://cme.nci.nih.gov/

HUMAN EMBRYONIC STEM CELLS (hESC):  Criteria for federal funding of research 
on hESCs can be found at http://grants.nih.gov/grants/stem_cells.htm and at  
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-005.html.  Only 
research using hESC lines that are registered in the NIH Human Embryonic Stem 
Cell Registry will be eligible for Federal funding (see http://escr.nih.gov).   
It is the responsibility of the applicant to provide the official NIH 
identifier(s)for the hESC line(s)to be used in the proposed research.  
Applications that do not provide this information will be returned without 
review. 

PUBLIC ACCESS TO RESEARCH DATA THROUGH THE FREEDOM OF INFORMATION ACT: The 
Office of Management and Budget (OMB) Circular A-110 has been revised to 
provide public access to research data through the Freedom of Information Act 
(FOIA) under some circumstances.  Data that are (1) first produced in a 
project that is supported in whole or in part with Federal funds and (2) cited 
publicly and officially by a Federal agency in support of an action that has 
the force and effect of law (i.e., a regulation) may be accessed through FOIA.  
It is important for applicants to understand the basic scope of this 
amendment.  NIH has provided guidance at 
http://grants.nih.gov/grants/policy/a110/a110_guidance_dec1999.htm.

Applicants may wish to place data collected under this PA in a public archive, 
which can provide protections for the data and manage the distribution for an 
indefinite period of time.  If so, the application should include a 
description of the archiving plan in the study design and include information 
about this in the budget justification section of the application. In 
addition, applicants should think about how to structure informed consent 
statements and other human subjects procedures given the potential for wider 
use of data collected under this award.

URLs IN NIH GRANT APPLICATIONS OR APPENDICES: All applications and proposals 
for NIH funding must be self-contained within specified page limitations. 
Unless otherwise specified in an NIH solicitation, Internet addresses (URLs) 
should not be used to provide information necessary to the review because 
reviewers are under no obligation to view the Internet sites.   Furthermore, 
we caution reviewers that their anonymity may be compromised when they 
directly access an Internet site.

HEALTHY PEOPLE 2010: The Public Health Service (PHS) is committed to achieving 
the health promotion and disease prevention objectives of "Healthy People 
2010," a PHS-led national activity for setting priority areas. This PA is 
related to one or more of the priority areas. Potential applicants may obtain 
a copy of "Healthy People 2010" at http://www.health.gov/healthypeople/

AUTHORITY AND REGULATIONS: This program is described in the Catalog of Federal 
Domestic Assistance No. 93.395, and is not subject to the intergovernmental 
review requirements of Executive Order 12372 or Health Systems Agency review.  
Awards are made under authorization of Sections 301 and 405 of the Public 
Health Service Act as amended (42 USC 241 and 284) and administered under NIH 
grants policies described at http://grants.nih.gov/grants/policy/policy.htm 
and under Federal Regulations 42 CFR 52 and 45 CFR Parts 74 and 92. 

The PHS strongly encourages all grant recipients to provide a smoke-free 
workplace and discourage the use of all tobacco products.  In addition, Public 
Law 103-227, the Pro-Children Act of 1994, prohibits smoking in certain 
facilities (or in some cases, any portion of a facility) in which regular or 
routine education, library, day care, health care, or early childhood 
development services are provided to children.  This is consistent with the 
PHS mission to protect and advance the physical and mental health of the 
American people.
