[Docket No. FDA-2016-N-0002]

New Animal Drugs for Use in Animal Feed; Approval of New Animal Drug Applications; Withdrawal of Approval of New Animal Drug Applications

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule; technical amendment.

SUMMARY:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of 71 supplemental new animal drug applications (NADAs) and 35 supplemental abbreviated new animal drug applications (ANADAs) for revised labeling reflecting a change in marketing status from over-the-counter (OTC) use to use by veterinary feed directive (VFD) for antimicrobial drugs of importance to human medicine administered to food-producing animals in medicated feed. Where applicable, FDA is also withdrawing approval of those parts of the NADAs that pertain to use of these antimicrobial drugs for growth promotion indications. These actions are being taken at the sponsors' requests because these particular medicated feeds will no longer be manufactured or marketed. These applications were submitted in voluntary compliance with the goals of FDA Center for Veterinary Medicine's (CVM's) Judicious Use Initiative. In addition, the animal drug regulations are being amended to reflect the voluntary withdrawal of approval of certain entire NADAs and ANADAs that were affected by this initiative. The animal drug regulations are also being amended to reflect several non-substantive changes in format. These technical amendments are being made to improve the consistency and readability of the regulations.

DATES:

This rule is effective December 30, 2016.

SUPPLEMENTARY INFORMATION:

I. Supplemental Approval of Revised Labeling and Withdrawal of Approval of Portions of NADAs Pertaining to Production Indications

FDA is amending the animal drug regulations to reflect approval of 71 supplemental NADAs and 35 supplemental ANADAs for revised labeling reflecting a change in marketing status from OTC use to use by VFD for antimicrobial drugs of importance to human medicine administered to food-producing animals in medicated feed. Where applicable, FDA is also withdrawing approval of those parts of the NADAs that pertain to use of these antimicrobial drugs for growth promotion indications. These actions are being taken at the sponsors' requests because these particular medicated feeds will no longer be manufactured or marketed.

These applications were identified as being affected by guidance for industry (GFI) #213, “New Animal Drugs and New Animal Drug Combination Products Administered in or on Medicated Feed or Drinking Water of Food-Producing Animals: Recommendations for Drug Sponsors for Voluntarily Aligning Product Use Conditions with GFI #209”, December 2013 (

http://www.fda.gov/downloads/AnimalVeterinary/GuidanceComplianceEnforcement/GuidanceforIndustry/UCM299624.pdf

). Their change to VFD marketing status is consistent with FDA CVM's initiative for the Judicious Use of Antimicrobials.

The animal drug regulations for medicated feeds are also being amended to reflect several non-substantive changes in format. These technical amendments are being made to improve the consistency and readability of the regulations.

The affected applications for Type A medicated articles for which supplemental applications with revised labeling were approved follow:

, FDA is amending the animal drug regulations to reflect approval of similar supplemental NADAs and ANADAs changing the marketing status of antimicrobial drugs administered to food-producing animals in medicated water.

II. Changes of Sponsorship

Elanco US Inc., 2500 Innovation Way, Greenfield, IN 46140 has informed FDA that it has transferred ownership of, and all rights and interest in, NADA 141-110, providing for the manufacture of combination drug medicated turkey feeds containing STAFAC (virginiamycin) and COBAN (monensin) to Phibro Animal Health Corp., GlenPointe Centre East, 3d Floor, 300 Frank W. Burr Blvd., Suite 21, Teaneck, NJ 07666. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect this change of sponsorship.

III. Withdrawals of Approval

In addition, approval of the following applications for medicated feeds containing antimicrobial drugs of importance to human medicine administered to food-producing animals is being withdrawn at the sponsors' requests because the products are no longer manufactured or marketed:

Special considerations

—(1) Federal law restricts medicated feed containing this veterinary feed directive (VFD) drug to use by or on the order of a licensed veterinarian. See § 558.6 for additional requirements.

(2) The expiration date of VFDs for oxytetracycline medicated feeds must not exceed 6 months from the date of issuance. VFDs for oxytetracycline shall not be refilled.

(3) Type C medicated feeds for cattle may be manufactured from tylosin liquid Type B medicated feeds which have a pH between 4.5 and 6.0 and which bear appropriate mixing directions as follows:

(i) For liquid feeds stored in recirculating tank systems: Recirculate immediately prior to use for not less than 10 minutes, moving not less than 1 percent of the tank contents per minute from the bottom of the tank to the top. Recirculate daily as described even when not used.

(ii) For liquid feeds stored in mechanical, air, or other agitation-type tank systems: Agitate immediately prior to use for not less than 10 minutes, creating a turbulence at the bottom of

the tank that is visible at the top. Agitate daily as described even when not used.
