II. 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 reside data) are not required for approval of an ANADA. An ANADA relies on the target animal safety drug effectiveness and human food safety data in the pioneer's new animal drug application. 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 (55 FR 24645, June 18, 1990; Fifth GADPTRA Policy Letter; Bioequivalence Guideline, April 1990).

The generic product was the subject of an approved suitability petition (92P-0057/CP1), in which the agency granted permission to The Upjohn Company to file an ANADA for changes in dosage form and in strength, relative to the pioneer product. The generic product is formulated as a solution, and the pioneer product is formulated as a water soluble powder. The generic product is formulated at 200 mg neomycin sulfate/mL, and the pioneer product is formulated at 325 g neomycin sulfate/pound of product. The pioneer and generic products will be administered as oral solutions in water or milk, at a dosage of 10 mg neomycin sulfate per pound of body weight in divided doses for a maximum of 14 days.

As a separate action, based upon the formulation characteristics of the pioneer and generic products, The Upjohn Company was granted a waiver from conducting an in vivo bioequivalence study. The pioneer and generic products will be administered as oral solutions at the same dosage, and the generic product does not contain any inactive ingredients that may significantly affect absorption of the active ingredient.

 

III. HUMAN FOOD SAFETY

Tolerance
A tolerance of 7.2 parts per million (ppm) is established for residues of parent neomycin (marker residue) in uncooked edible kidney (target tissue), 7.2 ppm in fat, 3.6 ppm in liver, 1.2 ppm in muscle of cattle, swine, sheep, and goats. A tolerance of 0.15 ppm is established for neomycin in milk.

Withdrawal Period
When a waiver of in vivo bioequivalence testing is granted, the withdrawal times are those previously assigned to the pioneer product. The withdrawal times are 1 day for cattle, 3 days for swine and goats, and 2 days for sheep (21 CFR 556.430).

Regulatory Method for Residues
The regulatory analytical method for detection of residues of the drug is a microbiological test using Staphylococcus epidermidis suspension. The method is published by the Food and Drug Administration, "Antibiotic Residues in Milk, Dairy Products and Animal Tissues: Methods, Reports, and Protocols", revised October 1968, reprinted December 1974.

 

IV. 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 Biosol Liquid (neomycin sulfate oral solution) when used under the proposed conditions of use, is safe and effective for its labeled indications.
