21 CFR Part 558


New Animal Drugs for Use in Animal Feeds; Lasalocid

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 Hoffmann-La Roche, Inc. The supplemental 
NADA provides for the use of a 20-percent lasalocid Type A medicated 
article in making Type C medicated feed used for growing turkeys as a 
coccidiostat.

EFFECTIVE DATE: June 5, 1995.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for 
Veterinary Medicine (HFV-135), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1643.

SUPPLEMENTARY INFORMATION: Hoffmann-La Roche, Inc., Nutley, NJ 07110, 
is the sponsor of NADA 96-298, which currently provides for the use of 
a Type A medicated article containing 20 percent (90.7 grams per pound 
(g/lb)) of lasalocid sodium activity in making a 68- to 113-g-per-ton 
(g/t) Type C medicated feed for broiler or fryer chickens and chukar 
partridges. The firm has filed a supplemental NADA that expands the use 
of the article to making a 68- to 113-g/t Type C medicated feed for 
growing turkeys for the prevention of coccidiosis caused by Eimeria 
meleagrimitis, E. gallopavonis, and E. adenoeides.
     The supplemental NADA is approved as of April 28, 1995, and the 
regulations are amended in 21 CFR 558.311 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 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 approval qualifies 
for 3 years of marketing exclusivity beginning April 28, 1995, because 
the supplemental application contains reports of new clinical or field 
investigations (other than bioequivalence or residue studies) essential 
to the approval of the application and conducted or sponsored by the 
applicant. The 3 years of marketing exclusivity applies only to the 
described use of lasalocid sodium in growing turkeys for which the 
supplemental application was approved.
    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.
