Dear Dr. Six:
The Supplement to your Product License Application for Diphtheria
and Tetanus Toxoids and Acellular Pertussis Vaccine, Adsorbed
(DTaP), to include the use of this product for the primary series
in infants and children as an additional indication, has been
approved.
This product is currently licensed in the U.S. as a fourth and/or
fifth dose in children 15 months to seven years of age (prior to
the seventh birthday) who have previously received a 3 or 4 dose
series of Diphtheria and Tetanus Toxoids and Pertussis Vaccine,
Adsorbed (Whole Cell Pertussis). With the approval of this
supplement, Tripedia® (DTaP) may now also be used for a three dose
primary series in children at least six weeks of age and for a
fourth dose in children who have received 3 doses of DTaP or DTP.
This approval also includes a single dose vial presentation. The
dating period for this product in the single dose vials shall be
18 months from the date of manufacture when stored at 2-8°C. The dating period of a final combination is based on the component with the shortest dating period and/or the first valid potency test, whichever is the shortest [21 CFR 610.50(a) and 21 CFR 610.53(b)].
We acknowledge the following commitments made by you in your correspondence to us:
- You have agreed to continue to collect data to support the
safety of Tripedia® as the fifth dose after 4 previous doses of Tripedia® (your letters dated July 12, 1996, and July 24, 1996). This study should be conducted under an IND.
After collection, these data should be submitted in the form
of a Supplement to your Product License Application along
with revised labeling, to support this indication.
- You have committed to conducting post-marketing surveillance studies (your letter dated July 24, 1996).
-
You have committed to continue monitoring for at least 5
years and to the administration of approximately 60,000
doses to children under 12 months of age during the
period of surveillance.
-
You have committed to reporting safety results annually,
The first report should be submitted no later than
August 1, 1997.
-
You have committed to examining the duration of protection
after a 4 dose series with Tripedia® by following a cohort
from the German case-control study for a period of five years
(your letter dated July 18, 1996). A study proposal should
be submitted to the Center for Biologics Evaluation and
Research no later than December 31, 1996.
This information will be placed on file in your product license
application.
Please submit three copies of final printed labeling at the time
of use and include part II of the label transmittal form with
completed implementation information. In addition, please submit
three copies of the introductory advertising and promotional
labeling. You may wish to submit the proposed materials in draft
form with a form 2567 to the Center for Biologics Evaluation and
Research, Advertising and Promotional Labeling Staff, HFM-202,
1401 Rockville Pike, Rockville, MD 20852-1448. Promotional claims
should be consistent with, and not contrary to, approved labeling. No comparative claims or claim of superiority over other similar products should be made unless data to support such claims are submitted to and approved by the Center for Biologics Evaluation.
It is requested that adverse experience reports for Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine, Adsorbed, be
submitted in accordance with the adverse experience reporting
requirements for licensed biological products (21 CFR 600.80) and
the Vaccine Injury Act, and that distribution reports be submitted as described in 21 CFR 600.81. Since your product is categorized as a vaccine, these reports should be submitted to the Vaccine Adverse Event Reporting System (VAERS) using the pre-addressed form VAERS-1.
