21 CFR Parts 520 and 556

 
New Animal Drugs; Albendazole

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplemental new animal drug 
application (NADA) filed by Pfizer, Inc. The supplemental NADA provides 
for use of albendazole oral suspension in nonlactating goats for the 
treatment of liver flukes.

DATES: This rule is effective February 29, 2008.

FOR FURTHER INFORMATION CONTACT: Joan C. Gotthardt, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8342, e-mail: 
joan.gotthardt@fda.hhs.gov.

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.

    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.
