SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, Div. of American
Home Products Corp., 800 Fifth St. NW., P.O. Box 518, Fort Dodge, IA
50501, filed original NADA 141-051 that provides for oral use of
ProHeartTM (moxidectin) tablets in dogs to prevent
infections by the canine heartworm Dirofilaria immitis and the
subsequent development of canine heartworm disease. The drug is limited
to use by or on the order of a licensed veterinarian.
The NADA is approved as of May 27, 1997, and the regulations are
amended by adding new 21 CFR 520.1451 to reflect the approval. The
basis for 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)(i) of the Federal Food, Drug, and
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(i)), this approval qualifies for
5 years of marketing exclusivity beginning May 27, 1997, because no
active ingredient of the drug, including any ester or salt of the
active ingredient, has been previously approved in any other
application filed under 512(b)(1) of the act.
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.
