New Animal Drugs; Gamithromycin

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 an original new animal drug 
application (NADA) filed by Merial, Ltd. The NADA provides for the 
veterinary prescription use of gamithromycin injectable solution for 
the management of bovine respiratory disease (BRD). FDA is also 
amending the regulations to add the established tolerances for residues 
of gamithromycin in edible tissues of cattle.

DATES: This rule is effective September 19, 2011.

FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8341, e-mail:

SUPPLEMENTARY INFORMATION: Merial Ltd., 3239 Satellite Blvd., Bldg. 
500, Duluth, GA 30096-4640 filed NADA 141-328 that provides for the 
veterinary prescription use of ZACTRAN (gamithromycin), an injectable 
solution, in beef and non-lactating dairy cattle for the treatment of 
BRD associated with Mannheimia haemolytica, Pasteurella multocida, and 
Histophilus somni; and for the control of respiratory disease in beef 
and non-lactating dairy cattle at high risk of developing BRD 
associated with M. haemolytica and P. multocida. The application is 
approved as of June 16, 2011, and the regulations are amended in 21 CFR 
parts 522 and 556 to reflect the approval.
    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.
