21 CFR Part 520


Oral Dosage Form New Animal Drugs; Dirlotapide

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 new animal drug application 
(NADA) filed by Pfizer, Inc. The NADA provides for the veterinary 
prescription use of dirlotapide solution in dogs for the management of 
obesity.

DATES:  This rule is effective January 4, 2007.

FOR FURTHER INFORMATION CONTACT:  Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-7540, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Pfizer, Inc., 235 East 42d St., New York, NY 
10017-5755, filed NADA 141-260 for SLENTROL (dirlotapide) Oral 
Solution. The NADA provides for the veterinary prescription use of 
dirlotapide solution in dogs for the management of obesity. The 
application is approved as of December 12, 2006, and the regulations 
are amended in 21 CFR part 520 by adding new Sec.  520.666 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 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 December 12, 2006.
    The agency has determined under 21 CFR 25.33(d)(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.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under

every month, as necessary, to maintain a target percent weight loss 
until the desired weight is achieved.
    (2) Indications for use. For the management of obesity.
    (3) Limitations. Federal law restricts this drug to use by or on 
the order of a licensed veterinarian.
