21 CFR Part 558


New Animal Drugs For Use In Animal Feed; Halofuginone 
Hydrobromide and Bambermycins

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 new animal drug application 
(NADA) filed by Hoechst-Roussel Agri-Vet Co. The NADA provides for 
using approved single ingredient Type A medicated articles to make Type 
C medicated turkey feeds containing halofuginone hydrobromide and 
bambermycins.

EFFECTIVE DATE: May 16, 1996.

FOR FURTHER INFORMATION CONTACT: James F. McCormack, Center For 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1607.

SUPPLEMENTARY INFORMATION: Hoechst-Roussel Agri-Vet Co., P.O. Box 2500, 
Route 202-206, Somerville, NJ 08876-1258, filed NADA 140-918 which 
provides for use of approved Stenorol (2.72 grams (g) of 
halofuginone hydrobromide activity per pound) and approved 
Flavomycin (4 and 10 g of bambermycins activity per pound) 
Type A medicated articles to make Type C medicated turkey feeds 
containing 1.36 to 2.72 g of halofuginone hydrobromide and 2 g of 
bambermycins per ton. The Type C medicated turkey feed is used for 
prevention of coccidiosis caused by Eimeria adenoides, E. 
meleagrimitis, and E. gallopavonis, and for increased rate of weight 
gain in growing turkeys. The NADA is approved as of May 16, 1996, and 
the regulations are amended in 21 CFR 558.265 by adding new paragraph 
(c)(2)(iii) 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, 12420 
Parklawn Dr., rm. 1-23, Rockville, MD 20857, between 9 a.m. and 4 p.m., 
Monday through Friday.
    This approval is for use of single ingredient Type A medicated 
articles to make Type C medicated feeds. Halofuginone hydrobromide is a 
Catagory II drug which, as provided in 21 CFR 558.4, requires an 
approved form FDA 1900 for making a Type C medicated feed. Therefore, 
use of halofuginone hydrobromide and bambermycins Type A articles to 
make Type C medicated turkey feeds as in NADA 140-918 requires an 
approved form FDA 1900.
    Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), approval of this 
application qualifies for 3 years of marketing exclusivity beginning 
May 16, 1996, because the application contains reports of new clinical 
or field investigations (other than bioequivalence or residue studies) 
or human food safety studies (other than bioequivalence or residue 
studies) essential to the approval and conducted or sponsored by the 
applicant.
    The agency has determined under 21 CFR 25.24 (d)(1)(ii) that this 
action is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.
