ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a new animal drug application (NADA) filed by Pfizer, Inc. The NADA provides for topical use of doramectin for treatment and control of certain worm, grub, lice, and mite infections of cattle. EFFECTIVE DATE: December 16, 1997. FOR FURTHER INFORMATION CONTACT: Estella Z. Jones, Center for Veterinary Medicine (HFV-135), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-594-1643. SUPPLEMENTARY INFORMATION: Pfizer, Inc., 235 East 42d St., New York, NY 10017-5755, is sponsor of NADA 141-095 that provides for the use of Dectomax(doramectin) 0.5 percent pour-on solution for beef cattle and female dairy cattle less than 20 months of age for treatment and control of gastrointestinal roundworms, lungworms, eyeworms, grubs, biting and sucking lice, and mange mites, to control infections and protect from reinfection with Cooperia oncophora and Dictyocaulus viviparus for 21 days, and Ostertagia ostertagia, C. punctata, and Oesophagostomum radiatum for 28 days after treatment. The NADA is approved as of September 16, 1997, and the regulations are amended by adding new Sec. 524.770 to reflect the approval. The basis of approval is discussed in the freedom of information summary. In accordance with the freedom of information provisions of 21 CFR part 20 and 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, 12420 Parklawn Dr., rm. 1-23, Rockville, MD 20857, 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 for food- producing animals qualifies for 3 years of marketing exclusivity beginning September 16, 1997, because the NADA contains substantial evidence of the effectiveness of the drug involved, studies of animal safety or, in the case of food-producing animals, human food safety studies (other than bioequivalence or residue studies) required for 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.
