          - 21 CFR Parts 520, 522, and 524
          - [Docket No. FDA-2011-N-0003]

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Final rule.

# SUMMARY:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect a change of sponsor for three approved new animal drug applications (NADAs) for dosage form products containing moxidectin from Fort Dodge Animal Health, Division of Wyeth, a wholly owned subsidiary of Pfizer, Inc., to Boehringer Ingelheim Vetmedica, Inc.

# DATES:

This rule is effective August 9, 2011.

# FOR FURTHER INFORMATION CONTACT:

                        Steven D. Vaughn, Center for Veterinary Medicine (HFV-100), Food and Drug Administration, 7520 Standish Pl., Rockville, MD 20855, 240-276-8300, e-mail:                         *steven.vaughn@fda.hhs.gov.*

# SUPPLEMENTARY INFORMATION:

Fort Dodge Animal Health, Division of Wyeth, a wholly owned subsidiary of Pfizer, Inc., 235 East 42d St., New York, NY 10017 has informed FDA that it has transferred ownership of, and all rights and interest in, the following three approved NADAs for dosage form products containing moxidectin to Boehringer Ingelheim Vetmedica, Inc., 2621 North Belt Highway, St. Joseph, MO 64506-2002: NADA 141-099, NADA 141-220, and NADA 141-247. Accordingly, the Agency is amending the regulations in 21 CFR parts 520, 522, and 524 to reflect the transfer of ownership.

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 Parts 520, 522, and 524

      - Animal drugs
