2. TARGET ANIMAL SAFETY and DRUG EFFECTIVENESS

Under the provisions of the Federal Food, Drug, and Cosmetic Act, as amended by the Generic Animal Drug and Patent Term Restoration Act, (53 FR 50460, December 15, 1988, First GADPTRA Policy Letter) an abbreviated new animal drug application (ANADA) may be submitted for a generic version of an approved new animal drug (pioneer product). New target animal safety data, drug effectiveness data, and human food safety data (other than tissue residue data) are not required for approval of an ANADA. An ANADA relies on bioeqivalence with the pioneer product to demonstrate target animal safety, drug effectiveness, and human safety.

Ordinarily, the ANADA sponsor shows that the generic product is bioequivalent to the pioneer. If bioequivalence is demonstrated through a clinical end-point study, then a tissue residue study to establish the withdrawal time for the generic product is also required. For certain dosage forms, the agency will grant a waiver from conducting an in vivo bioequivalence study (Fifth GADPTRA Policy Letter: 55 FR 24645, June 18, 1990; Bioequivalence Guidance: 61 FR 26182 - 26186, May 24, 1996).

Based upon the formulation characteristics of the generic product, Lloyd Incorporated was granted a waiver from conducting an in vivo bioequivalence study forVetaKetTM. The generic and pioneer products contain the same active and inactive ingredients and are injectable solutions.

 

3. HUMAN SAFETY:

Human Safety Relative to Food Consumption:

None required as VetaKetTM Liquid is intended for use only in cats and subhuman primates. The labeling includes the statement, "For Intramuscular use in Cats and Subhuman Primates Only".

Human Safety Relative to Possession, Handling, and Administration:

Labeling contains adequate caution/warning statements.

 

4. AGENCY CONCLUSIONS:

This ANADA submitted under section 512(b) of the Federal Food, Drug and Cosmetic Act satisfies the requirements of section 512(n) of the Act and demonstrates that VetaketTM (ketamine hydrochloride injection, USP), when used under the proposed conditions of use, is safe and effective for the labeled indications.
