AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplemental new animal drug 
application (NADA) filed by Fort Dodge Animal Health. The supplemental 
NADA provides for use of an implant containing 100 milligrams (mg) 
trenbolone acetate and 14 mg estradiol benzoate for increased rate of 
weight gain in steers fed in confinement for slaughter.

DATES: This rule is effective December 27, 2002.

FOR FURTHER INFORMATION CONTACT: Daniel A. Benz, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0223, e-mail: [email protected].

SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, Division of Wyeth, 
800 Fifth St. NW., Fort Dodge, IA 50501, filed a supplement to NADA 
141-043 for SYNOVEX (trenbolone acetate and estradiol benzoate) 
implants. The supplemental NADA provides for use of SYNOVEX Choice, an 
implant containing 100 mg trenbolone acetate and 14 mg estradiol 
benzoate, for increased rate of weight gain in steers fed in 
confinement for slaughter. The supplemental NADA is approved as of 
October 3, 2002, and the regulations are amended in 21 CFR 522.2478 to 
reflect the approval. The basis of approval is discussed in the freedom 
of information summary.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and Sec.  514.11(e)(2)(ii), a summary of safety and 
effectiveness data and information submitted to support approval of 
this supplemental application may be seen in the Dockets Management 
Branch (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)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval 
qualifies for 3 years of marketing exclusivity beginning October 3, 
2002.
    The agency has determined under 21 CFR 25.33(a)(1) 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.
