SUPPLEMENTARY INFORMATION: Intervet, Inc., P.O. Box 318, 29160 Intervet Ln., Millsboro, DE 19966, filed NADA 141-269 that provides for REVALOR XS (trenbolone acetate and estradiol), an ear implant, used for increased rate of weight gain and improved feed efficiency in steers fed in confinement for slaughter. The supplemental NADA is approved as of January 19, 2007, and the regulations are amended in Sec. 522.2477 (21 CFR 522.2477) to reflect the approval. The basis of approval is discussed in the freedom of information summary.
In addition, FDA is revising the regulations in Sec. 522.2477 to correctly reflect products approved for another sponsor. This action is being taken to improve the accuracy of the regulations.
In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application 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.
Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning January 19, 2007.
FDA has determined under 21 CFR 25.33(a)(1) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.
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.
