At this time, the regulations are being amended to reflect these changes of sponsorship.
In addition, Paladin Labs (USA), Inc., 160 Greentree Dr., Suite 101, Dover, DE 19904 has requested that FDA withdraw approval of NADA 141-075 for ANTIZOL-VET (fomepizole) Injection. Elsewhere in this issue of the *Federal Register,* FDA gave notice that approval of NADA 141-075, and all supplements and amendments thereto, is withdrawn, effective April 20, 2015. As provided in the regulatory text of this document, the animal drug regulations are being amended to reflect this voluntary withdrawal of approval.
Following these changes of sponsorship and withdrawal of approval, Hemoglobin Oxygen Therapeutics, LLC is now the sponsor of an approved application while OPK Biotech, LLC and Paladin Labs (USA), Inc., are no longer the sponsor of an approved application. Also, Merial Ltd., 3239 Satellite Blvd., Bldg. 500, Duluth, GA 30096-4640, has informed FDA that it has changed its name to Merial, Inc., and Intervet, Inc., 556 Morris Ave., Summit, NJ 07901, has informed FDA that it has changed its address to 2 Giralda Farms, Madison, NJ 07940. Accordingly, § 510.600 (21 CFR 510.600) is being amended to reflect these changes.
In addition, FDA is amending the tables in § 510.600(c) to remove listings for International Nutrition, Inc.; NutriBasics Co.; Seeco Inc.; Southern Micro-Blenders, Inc.; and Wellmark International because these firms are no longer the sponsor of an approved application. These technical amendments are 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.
