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 Intervet, Inc. The supplemental NADA 
provides for the veterinary prescription use of an injectable 
suspension of porcine insulin zinc for the reduction of hyperglycemia 
and hyperglycemia-associated clinical signs in cats with diabetes 
mellitus.

DATES: This rule is effective April 18, 2008.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8337, e-mail:

SUPPLEMENTARY INFORMATION: Intervet, Inc., P.O. Box 318, 29160 Intervet 
Lane, Millsboro, DE 19966, filed a supplement to NADA 141-236 providing 
for the veterinary prescription use of VETSULIN (porcine insulin zinc) 
Suspension for the reduction of hyperglycemia and hyperglycemia-
associated clinical signs in cats with diabetes mellitus. The 
application also provides for a lower initial dosage of insulin for 
dogs. The supplemental NADA is approved as of March 24, 2008, and the 
regulations are amended in 21 CFR 522.1160 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.
    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.
    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 approval qualifies for 
3 years of marketing exclusivity beginning on the date of approval. The 
three years of marketing exclusivity applies only to the indication for 
use in cats for which this supplement is approved.
    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.

* * * * *
    (c) Conditions of use--(1) Dogs--(i) Amount. Administer an initial 
once-daily dose of 0.5 IU per kilogram of body weight by subcutaneous 
injection concurrently with or right after a meal. Adjust this once-
daily dose at appropriate intervals based on clinical signs, urinalysis 
results, and glucose curve values until adequate glycemic control has 
been attained. Twice-daily therapy should be initiated if the duration 
of insulin action is determined to be inadequate. If twice-daily 
treatment is initiated, the two doses should be 25 percent less than 
the once daily dose required to attain an acceptable nadir.
    (ii) Indications for use. For the reduction of hyperglycemia and 
hyperglycemia-associated clinical signs in dogs with diabetes mellitus.

injection. Injections should be given twice daily at approximately 12-
hour intervals. For cats fed twice daily, the injections should be 
concurrent with or right after a meal. For cats fed ad libitum, no 
change in feeding is needed. Adjust the dose at appropriate intervals 
based on clinical signs, urinalysis results, and glucose curve values 
until adequate glycemic control has been attained.
    (ii) Indications for use. For the reduction of hyperglycemia and 
hyperglycemia-associated clinical signs in cats with diabetes mellitus.
    (iii) Limitations. Federal law restricts this drug to use by or on 
the order of a licensed veterinarian.
