DOCUMENT 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 hyperglycemiaassociated clinical signs in cats with diabetes mellitus.

SUMMARY: Insulin,

SUPPLEMENTAL INFORMATION

Intervet, Inc., P.O. Box 318, 29160 Intervet Lane, Millsboro, DE 19966, filed a supplement to NADA 141236 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 (HFA305), 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. 801808.
