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

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 actions for new animal drug applications (NADAs) and abbreviated new animal drug applications (ANADAs) during August 2014. FDA is also informing the public of the availability of summaries of the basis of approval and of environmental review documents, where applicable. The animal drug regulations are also being amended to reflect a change of sponsorship of two NADAs and one ANADA, and to reflect a revised food safety warning.

DATES:

This rule is effective October 28, 2014.

FOR FURTHER INFORMATION CONTACT:

George K. Haibel, Center for Veterinary Medicine (HFV-6), Food and Drug Administration, 7519 Standish Pl., Rockville, MD 20855, 240-276-9019, george.haibel@fda.hhs.gov.

SUPPLEMENTARY INFORMATION:

FDA is amending the animal drug regulations to reflect approval actions for NADAs and ANADAs during August 2014, as listed in table 1. In addition, FDA is informing the public of the availability, where applicable, of documentation of environmental review required under the National Environmental Policy Act (NEPA) and, for actions requiring review of safety or effectiveness data, summaries of the basis of approval (FOI Summaries) under the Freedom of Information Act (FOIA). These public documents may be seen in the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday. Persons with access to the Internet may obtain these documents at the CVM FOIA Electronic Reading Room: https://www.fda.gov/AboutFDA/CentersOffices/OfficeofFoods/CVM/CVMFOIAElectronicReadingRoom/default.htm. Marketing exclusivity and patent information may be accessed in FDA's publication, Approved Animal Drug Products Online (Green Book) at: https://www.fda.gov/AnimalVeterinary/Products/ApprovedAnimalDrugProducts/default.htm.

In addition, Macleod Pharmaceuticals, Inc., 2600 Canton Ct., Fort Collins, CO 80525 has transferred ownership of, and all rights and interest in ANADA 200-033 for UNIPRIM (trimethoprim and sulfadiazine) Powder to Neogen Corp. (Neogen), 944 Nandino Blvd., Lexington, KY 40511. In 2004, Hess & Clark, Inc., transferred ownership of, and all rights and interest in NADA 011-154 for NFZ Puffer (nitrofurazone soluble powder) and NADA 140-851 for NFZ Wound Dressing (nitrofurazone ointment) to Neogen. At this time, the regulations are being amended to reflect these transfers.

Following these changes of sponsorship, Macleod Pharmaceuticals, Inc., and Hess & Clark, Inc., will no longer be the sponsor of an approved application. Accordingly, 21 CFR 510.600(c) is being amended to remove the entries for these firms.

Also, the animal drug regulations are being amended in 21 CFR 522.690 to revise a human food safety warning for dinoprost tromethamine injectable solution. This amendment is being made 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.
