SUPPLEMENTARY INFORMATION:

Fort Dodge Animal Health, Division of Wyeth, a wholly owned subsidiary of Pfizer, Inc., 235 East 42d St., New York, NY 10017 (Pfizer) has informed FDA that it has transferred ownership of, and all rights and interest in, the following 18 approved NADAs and 1 approved ANADA to Boehringer Ingelheim Vetmedica, Inc., 2621 North Belt Highway, St. Joseph, MO 64506-2002 (Boehringer): NADA 15-030, 32-702, 34-879, 45-290, 55-021, 55-022, 55-030, 55-048, 55-054, 55 058, 97-222, 108-114, 119-688, 140-684, 140-806, 140-854, 141-096, and 141-274; and ANADA 200-088. In addition, Fort Dodge Animal Health, Division of Wyeth Holdings Corp., a wholly owned subsidiary of Pfizer, has informed FDA that it has transferred ownership of, and all rights and interest in, the following 15 approved NADAs to Boehringer: NADA 6-084, 8-774, 12-198, 13-624, 33-127, 33-318, 33-319, 33-373, 40-181, 46-146, 65-269, 99-388, 122-271, 122-272, and 141-108. Accordingly, the agency is amending the regulations in 21 CFR parts 520, 522, 524, and 526 to reflect the transfer of ownership. In addition, several sections are being revised to reflect the current format.

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.
