21 CFR Part 558

 

New Animal Drugs for Use In Animal Feeds; Salinomycin In 
Combination With Roxarsone and Lincomycin, or Virginiamycin, or 
Roxarsone and Virginiamycin

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 three abbreviated new animal 
drug applications (ANADA's) filed by Hoechst-Roussel Agri-Vet Co. The 
ANADA's provide for using approved Type A medicated articles to make 
Type C medicated broiler feeds containing salinomycin with 
virginiamycin, salinomycin with roxarsone and virginiamycin, or 
salinomycin with roxarsone and lincomycin.

EFFECTIVE DATE: May 20, 1994.

FOR FURTHER INFORMATION CONTACT: Glenn A. Peterson, Center for 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1602.

SUPPLEMENTARY INFORMATION: Hoechst-Roussel Agri-Vet Co., P.O. Box 2500, 
Somerville, NJ 08876-1258, filed the following ANADA's:
     ANADA 200-090, salinomycin with roxarsone and lincomycin, provides 
for using approved single ingredient Type A medicated articles to make 
Type C medicated broiler feeds containing 40 to 60 grams per ton (g/t) 
of salinomycin sodium activity with 45.4 g/t of roxarsone and 2 g/t of 
lincomycin for the prevention of coccidiosis caused by Eimeria tenella, 
E. necatrix, E. acervulina, E. maxima, E. brunetti, and E. mivati, 
including some field strains of E. tenella that are more susceptible to 
roxarsone combined with salinomycin than to salinomycin alone, and for 
improved feed efficiency. The ANADA is approved as a generic copy of 
Agri-Bio Corp.'s new animal drug application (NADA) 140-581.
     ANADA 200-092, salinomycin with virginiamycin, provides for using 
approved single ingredient Type A medicated articles to make Type C 
medicated broiler feeds containing 40 to 60 g/t of salinomycin sodium 
activity with either: (1) 5 g/t of virginiamycin for the prevention of 
coccidiosis caused by the aforementioned Eimeria species, and for 
increased rate of weight gain and improved feed efficiency, or (2) 5 to 
15 g/t of virginiamycin for the prevention of coccidiosis caused by the 
aforementioned Eimeria species and for increased rate of weight gain. 
The ANADA is approved as a generic copy of SmithKline Beecham Animal 
Health's NADA 138-828.
     ANADA 200-094, salinomycin with roxarsone and virginiamycin, 
provides for using approved single ingredient Type A medicated articles 
to make Type C medicated broiler feeds containing 40 to 60 g/t of 
salinomycin sodium activity with 45.4 g/t of roxarsone and 5 g/t 
virginiamycin for prevention of coccidiosis caused by the 
aforementioned Eimeria species, including some field strains of E. 
tenella which are more susceptible to roxarsone combined with 
salinomycin than to salinomycin alone, and for improved feed 
efficiency. The ANADA is approved as a generic copy of SmithKline 
Beecham Animal Health's NADA 138-953.
     ANADA's 200-090 and 200-094 are approved as of May 20, 1994. ANADA 
200-092 is approved as of April 6, 1994. The regulations are amended in 
Sec. 558.550 Salinomycin (21 CFR 558.550) to reflect the approvals.
     These approvals are for use of Type A medicated articles to make 
Type C medicated feeds. Roxarsone is a Category II drug which, as is 
provided in Sec. 558.4(a) and (d), requires an approved Form FDA 1900 
to make Type C medicated feeds. Use of salinomycin in combination with 
roxarsone and lincomycin, or salinomycin in combination with roxarsone 
and virginiamycin to make Type C medicated feeds as in ANADA's 200-090 
and 200-094, respectively, requires an approved Form FDA 1900.
     In addition, FDA published a final rule in the Federal Register of 
October 8, 1991 (56 FR 50652), that announced a change of sponsor name 
from ``SmithKline Animal Health Products, Division of SmithKline 
Beckman Corp.'' to ``SmithKline Beecham Animal Health.'' The change of 
sponsor name affected NADA 091-467 (virginiamycin), however, the 
references concerning virginiamycin in Sec. 558.550(b)(1)(x), 
(b)(1)(xi), and (b)(1)(xii) were not amended to reflect the new sponsor 
name. At this time, those references are amended.
     Finally, when Sec. 558.550(b)(1)(xii)(b) was codified, an error 
was made in the indications language and it is now corrected to read 
``* * * which are more susceptible to roxarsone combined with 
salinomycin than to salinomycin alone, * * *.''
    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.
    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.

 List of Subjects in 21 CFR Part 558

     Animal drugs, Animal feeds.
     Therefore, under the Federal Food, Drug, and Cosmetic Act and 
under authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:

PART 558--NEW ANIMAL DRUGS FOR USE IN ANIMAL FEEDS

     1. The authority citation for 21 CFR part 558 continues to read as 
follows:

    Authority: Secs. 512, 701 of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b, 371).

Sec. 558.550  [Amended]

     2. Section 558.550 Salinomycin is amended in paragraph (a)(2) by 
adding ``(b)(1)(x), (b)(1)(xi), (b)(1)(xii), and (b)(1)(xiv)'' after 
``(b)(1)(viii)'', in paragraphs (b)(1)(x)(c) and (b)(1)(xii)(c) by 
removing ``000007'' and adding in its place ``053571'', and paragraph 
(b)(1)(xii)(b) by revising the phrase ``salinomycin than to roxarsone 
alone,'' to read ``salinomycin than to salinomycin alone''.

    Dated: May 13, 1994.
