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 Merck Research Laboratories, Division of 
Merck & Co., Inc. The supplement provides for subcutaneous use of 
ivermectin injection as an antiparasitic in ranch-raised foxes.

EFFECTIVE DATE: August 30, 1995.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, -Center for 
Veterinary Medicine (HFV-135), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Merck Research Laboratories, Division of 
Merck & Co., Inc., P.O. Box 2000, Rahway, NJ 07065, is sponsor of NADA 
128-409 which provides for the use of Ivomec Injection 
(ivermectin) as an antiparasitic for horses, cattle, reindeer, and 
swine. The supplement provides for use of 0.27 percent ivermectin as an 
antiparasitic for treatment and control of ear mites (Otodectes 
cynotis) in ranch-raised foxes. Approval is based in part on data and 
information in Public Master File (PMF) 5307 established under the 
National Research Support Project No. 7 (NRSP-7) (formerly the 
Interregional Research Project No. 4 (IR-4)), Northcentral Region, 
Michigan State University, East Lansing, MI 48824. The supplemental 
NADA is approved as of July 13, 1995, and the regulations are amended 
in Sec. 522.1192 (21 CFR 522.1192) to reflect the approval. The basis 
of approval is discussed in the freedom of information summary. Also, 
the heading of Sec. 522.1192 is amended to read ''Ivermectin 
injection.''
    In accordance with the freedom of information provisions of part 20 
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (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 Dockets 
Management Branch (HFA-305), Food and Drug Administration, rm. 1-23, 
12420 Parklawn Dr., Rockville, MD 20857, between 9 a.m. and 4 p.m., 
Monday through Friday.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplement does not 
qualify for marketing exclusivity because the supplement does not 
contain reports of new clinical or field investigations (other than 
bioequivalence or residue studies) essential to the approval and 
conducted or sponsored by the applicant.
    The agency has carefully considered the potential environmental 
effects of this action. FDA has concluded that the action will not have 
a significant impact on the human environment, and that an 
environmental impact statement is not required. The agency's finding of 
no significant impact and the evidence supporting that finding, 
contained in an environmental assessment, may be seen in the Dockets 
Management Branch (address above) between 9 a.m. and 4 p.m., Monday 
through Friday.
