[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 eight supplemental new animal 
drug applications (NADAs). The effect of these supplemental 
applications will be to change the marketing status from over-the-
counter (OTC) use to use by veterinary feed directive (VFD) for these 
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 production 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 
abbreviated new animal drug applications (ANADAs) that were affected by 
this initiative.

DATES: This rule is effective February 24, 2017.

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 
eight supplemental NADAs 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 production 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 from OTC to VFD marketing status is consistent with FDA CVM's 
initiative for the Judicious Use of Antimicrobials.
    The affected applications for Type A medicated articles for which 
supplemental applications with revised labeling were approved are as 
follows:

    Elsewhere in this issue of the Federal Register, FDA gave notice 
that approval of NADAs 044-820, 044-972, 047-261, 047-262, 048-954, 
091-513, 092-482, 093-106, 101-689, 122-481, 122-608, 122-822, 137-537, 
138-792, 138-828, 138-904, 141-110, and 141-150, and ANADAs 200-092 and 
200-093, and all supplements and amendments thereto, is withdrawn, 
effective February 24, 2017. As provided in the regulatory text of this 
document, the animal drug

[[Page 11512]]

regulations are amended to reflect these voluntary withdrawals of 
approval.
    A similar rule published in the Federal Register of December 27, 
2016 (81 FR 94991), amended the approved conditions of use in 21 CFR 
part 558 to reflect approval of an additional 106 supplemental NADAs 
and supplemental ANADAs for the manufacture of medicated feeds for 
administration of antimicrobial drugs to food-producing animals and the 
voluntary withdrawal of approval of 11 NADAs and 4 ANADAs.
    This rule does not meet the definition of ``rule'' in 5 U.S.C. 
804(3)(A) because it is a rule of ``particular applicability.'' 
Therefore, it is not subject to the congressional review requirements 
in 5 U.S.C. 801-808.

List of Subjects in 21 CFR Part 558

    Animal drugs, Animal feeds.

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:
