Dear Mr. Quinn:

We have approved your request to supplement your biologics license application (BLA) for Tetanus and Diphtheria Toxoids Adsorbed (DECAVAC®), to revise the package insert to include additional safety and immunogenicity data obtained from the DECAVAC group of study Td506.

Please provide your final content of labeling in Structured Product Labeling (SPL) format and include the carton and container labels.  In addition, please submit three original paper copies for carton and container final printed labeling. All final labeling should be submitted as Product Correspondence to this BLA at the time of use (prior to marketing) and include implementation information on FDA Form 356h.

In addition, please submit the final content of labeling (21 CFR 601.14) in SPL format via the FDA automated drug registration and listing system, eLIST, as described at
. Information on submitting SPL files using eLIST may be found in the guidance for industry titled, “SPL Standard for Content of Labeling Technical Qs and As” at

You may submit two draft copies of the proposed introductory advertising and promotional labeling with an FDA Form 2253 to the Center for Biologics Evaluation and Research, Advertising and Promotional Labeling Branch, HFM-602, 1401 Rockville Pike, Rockville, MD 20852-1448. You must submit copies of your final advertisement and promotional labeling at the time of initial dissemination or publication, accompanied by Form FDA 2253 (21 CFR 601.12(f)(4)).

All promotional claims must be consistent with and not contrary to approved labeling.  You should not make a comparative promotional claim or claim of superiority over other products unless you have substantial evidence or substantial clinical experience to support such claims (21 CFR 202.1(e)(6)).

Please submit an amendment to all pending supplemental applications for this BLA that include revised labeling incorporating a revised content of labeling that includes these changes.

This fulfills your commitment to submit a Supplement with a revised package insert incorporating additional safety and immunogenicity data obtained from the DECAVAC group of study Td506, entitled “Safety and Immunogenicity of Tetanus and Diphtheria Toxoids Adsorbed Combined with Component Pertussis (TdcP) Vaccine Compared to Tetanus and Diphtheria Toxoids Adsorbed (Td) in Adolescents and Adults 11 – 64 Years of Age," as stated in your commitment in the December 9, 2008, approval letter for STN 103921/5095.
