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 residue 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).
Based upon the formulation characteristics of the generic product, Agri Laboratories. Ltd. was granted a waiver from conducting an in vivo bioequivalence study for tetracycline hydrochloride soluble powder. The generic and pioneer products are soluble powders with the same active and inactive ingredients. The generic and pioneer products also contain the same concentration of active ingredient.
III. HUMAN FOOD SAFETY:
Tolerance for the marker residue
The tolerance for the pioneer product applies to the generic product.
A tolerance of 0.25 ppm (negligible residue) is established for tetracycline residues in the uncooked edible tissues of calves, swine, chickens and turkeys under 21 CFR 556.720.
When a waiver of the in vivo bioequivalence study is granted, the generic product withdrawal times are those previously assigned to the pioneer product (21 CFR 520. 2345d).
Withdrawal Times: 4 days in swine, chickens and turkeys; 5 days in cattle
The analytical method for the determination of tetracycline in tissues uses a microbiological procedure. This method is found in the Antibiotic Residues in Milk, Dairy Products, and Animal Tissues: Methods, Reports and Protocols, revised October 1968, National Center for Antibiotic and Insulin Analysis, FDA, Washington, D.C. 20204.
IV. AGENCY CONCLUSIONS:
This ANADA satisfies the requirements of section 512 of the Act and demonstrates that tetracycline hydrochloride, when used under its proposed conditions of use, is safe and effective for its labeled indications.
