[[Page 27889]]

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a new animal drug application 
(NADA) filed by Pfizer, Inc. The NADA provides for the veterinary 
prescription use of gonadotropin releasing factor-diphtheria toxoid 
conjugate by subcutaneous injection for temporary immunological 
castration (suppression of testicular function) and reduction of boar 
taint in intact male pigs intended for slaughter.

DATES: This rule is effective May 13, 2011.

FOR FURTHER INFORMATION CONTACT: Matthew Lucia, Center for Veterinary 
Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 240-276-8116, e-mail: matthew.lucia@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Pfizer, Inc., 235 East 42d St., New York, NY 
10017-5755, filed NADA 141-322 that provides for the veterinary 
prescription use of IMPROVEST (gonadotropin releasing factor-diphtheria 
toxoid conjugate) Sterile Solution for Injection for temporary 
immunological castration (suppression of testicular function) and 
reduction of boar taint in intact male pigs intended for slaughter. The 
application is approved as of March 22, 2011, and the regulations are 
amended in 21 CFR part 522 to reflect 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)(i) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(i)), this approval qualifies for 
5 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.

List of Subjects in 21 CFR Part 522

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 522 is 
amended as follows:
