SUPPLEMENTARY INFORMATION:

Pfizer, Inc., 235 East 42d St., New York, NY 10017, filed a supplement to NADA 110-048 that provides for the use of VALBAZEN (albendazole) Oral Suspension for the treatment of liver flukes in nonlactating goats. The approval of this supplemental NADA relied on publicly available safety and effectiveness data contained in Public Master File (PMF) 5582, which were compiled under National Research Support Project-7 (NRSP-7), a national agricultural research program for obtaining clearances for use of new drugs in minor animal species and for special uses. The supplemental NADA is approved as of January 24, 2008, and the regulations are amended in 21 CFR 520.45a and 556.34 to reflect the approval.

In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of the 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.Start Printed Page 11027

Under section 573(c) of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C.360ccc-2(c)), this approval qualifies for 7 years of exclusive marketing rights beginning on the date of approval, because the new animal drug has been declared a designated drug by FDA under section 573(a) of the Act.

The agency has determined under 21 CFR 25.33(d)(4) 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.
