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.

[top] 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.
