[Federal Register Volume 81, Number 248 (Tuesday, December 27, 2016)] [Rules and Regulations] [Pages 94991-95025] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-31083] ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration 21 CFR Parts 556 and 558 [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. FOR FURTHER INFORMATION CONTACT: George K. Haibel, Center for Veterinary Medicine (HFV-6), Food and Drug Administration, 7519 Standish Pl., Rockville, MD 20855, 240-402-5689, [email protected]. 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: ------------------------------------------------------------------------ File No. Animal drug product Sponsor ------------------------------------------------------------------------ 006-391.............

These technical amendments are being made to improve the consistency and readability of the regulations. Elsewhere in this issue of the Federal Register, 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: ------------------------------------------------------------------------ File No. Product name Sponsor ------------------------------------------------------------------------ 034-085................
