    heartworm disease in dogs.

    FOR FURTHER INFORMATION CONTACT: Marcia K. Larkins, Center for 
    Veterinary Medicine (HFV-112), Food and Drug Administration, 7500 
    Standish Pl., Rockville, MD 20855, 301-827-0137.
    
    SUPPLEMENTARY INFORMATION: Rhone Merieux, Inc., 7101 College Blvd., 
    suite 610, Overland Park, KS 66210, filed NADA 141-042 to provide for 
    intramuscular use of the injectable drug product Immiticide Sterile 
    Powder which consists of a vial of lyophilized powder containing 50 
    milligrams of melarsomine dihydrochloride to be reconstituted with the 
    provided 2 milliliters of sterile water. The drug is indicated for the 
    treatment of stabilized, class 1, 2, and 3 heartworm disease 
    (asymptomatic to mild, moderate, and severe, respectively) caused by 
    immature (4 month-old, stage L5) to mature adult infections of 
    Dirofilaria immitis in dogs. The drug product is available by 
    prescription. The NADA is approved as of July 21, 1995, and the 
    regulations are amended in part 522 (21 CFR part 522) by adding new 
    Sec. 522.1362 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 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)(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 July 21, 1995, because no 
    active ingredient 
    
    [[Page 49340]]
    (including any ester or salt of the active ingredient) has been 
    approved in any other application under section 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.
