[Docket No. FDA-2014-N-0002]

Oral Dosage Form New Animal Drugs; Change of Sponsor

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendments.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal
drug regulations to reflect a change of sponsor for 172 approved new
animal drug applications (NADAs) and 14 approved abbreviated new animal
drug applications (ANADAs) for oral dosage form new animal drug
products from Pfizer, Inc., including its several subsidiaries and
divisions, to Zoetis, Inc. FDA is also amending the animal drug
regulations to remove entries describing conditions of use for new
animal drug products for which no NADA is approved, to make minor
corrections, and to reflect a current format. This is being done to
increase the accuracy and readability of the regulations.

DATES: This rule is effective May 20, 2014.

    Accordingly, the Agency is amending the regulations in 21 CFR part
520 to reflect these transfers of ownership. Also, the regulations are
being amended to make minor corrections and to reflect a current
format. This is being done to increase the accuracy and readability of
the regulations.
    Following this change of sponsorship, Pfizer, Inc., and its wholly
owned subsidiaries are no longer sponsors of an approved NADA.
Accordingly, the Agency is amending the regulations in 21 CFR
510.600(c) to reflect this change of sponsorship.
    In addition, FDA has noticed that certain sections of part 520
contain entries describing conditions of use for new animal drug
products for which no NADA is approved. These errors were introduced by
the Agency during the 1992 recodification of the regulations for
certifiable antibiotics (57 FR 37318,

August 18, 1992). That rule did not identify whether particular
regulations were the subject of an approved NADA and consequently
resulted in codification of certain conditions of use for which there
is no approved NADA. At this time, the Agency is amending the
regulations to remove these entries. This action is being taken to
improve the accuracy of the regulations.
    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

21 CFR Part 510

    Administrative practice and procedure, Animal drugs, Labeling,
Reporting and recordkeeping requirements.

21 CFR Part 520
