Pfizer, Inc., 235 East 42d St., New York, NY 10017, filed a supplement to NADA 141-322 for IMPROVEST (gonadotropin releasing factor analog-diphtheria toxoid conjugate) Sterile Solution for Injection, administered as two doses 4 weeks apart to intact male pigs for the reduction of boar taint. The supplement extends the slaughter interval from 4 to 8 weeks after the second dose to 3 to 10 weeks. The supplemental NADA is approved as of November 30, 2011, and the regulations in 21 CFR 522.1083 are amended to reflect the approval.
In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application may be seen in the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this supplemental approval qualifies for 3 years of marketing exclusivity beginning on the date of approval.
The Agency has determined under 21 CFR 25.33 that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.
This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability.” Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
