21 CFR Part 558

 

New Animal Drugs For Use In Animal Feeds; Tiamulin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect the approval of a supplemental new animal 
drug application (NADA) filed by Fermenta Animal Health Co. The 
supplemental NADA provides for the use of tiamulin (Denagard) 
Type A medicated article to make a Type C medicated feed used for the 
treatment of swine dysentery.

EFFECTIVE DATE:  August 16, 1994.

FOR FURTHER INFORMATION CONTACT:  George K. Haibel, Center for 
Veterinary Medicine (HFV-133), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1644.

SUPPLEMENTARY INFORMATION: Fermenta Animal Health Co., 10150 North 
Executive Hills Blvd., Kansas City, MO 64153, is the sponsor of NADA 
139-472, which was approved on July 17, 1987 (52 FR 26955), for the use 
of tiamulin Type A medicated articles in the preparation of Type C 
medicated swine feeds. As first approved, the Type C medicated feed 
containing 35 grams per ton (g/t) of tiamulin could be used to control 
swine dysentery. The Type C medicated feed containing 10 g of tiamulin 
per ton could be used for increased rate of weight gain from weaning to 
56.70 kilograms (kg) (125 pounds (lb)), which was later approved to 
113.40 kg (250 lb) on October 6, 1988 (53 FR 39257). The sponsor has 
submitted a supplemental application providing for the use of tiamulin 
Type A medicated article containing 5, 10, or 113.4 g/lb of tiamulin 
hydrogen fumarate to make a Type C medicated swine feed containing 200 
g/t of tiamulin for the treatment of swine dysentery.
    The supplemental NADA is approved as of July 7, 1994, and the 
regulations are amended by modifying Sec. 558.600 (21 CFR 558.600) to 
reflect the approval. The basis for approval is discussed in the 
freedom of information summary. In addition, the regulation is amended 
by modifying the genera ``Treponema'' to include the currently 
scientifically accepted genera name ``Serpulina.''
    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 exclusivity beginning July 7, 1994, 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 by the applicant. The 
3 years of marketing exclusivity applies only to the new claim ``for 
treatment of swine dysentery'' for which the supplemental application 
was approved.
    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 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.

    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:

Cosmetic Act (21 U.S.C. 360b, 371).

    2. Section 558.600 Tiamulin is amended in paragraph (c)(1)(i) by 
removing the word ``Treponema'' and adding in its place the words 
``Serpulina (Treponema)'' and by adding new paragraph (c)(3) to read as 
follows:


Sec. 558.600  Tiamulin.

* * * * *
    (c) * * *
    (3) Amount. 200 grams of tiamulin per ton.
    (i) Indications for use. Treatment of swine dysentery associated 
with Serpulina (Treponema) hyodysenteriae susceptible to tiamulin.
    (ii) Limitations. Feed continuously as the sole feed for 14 
consecutive days. Withdraw feed 7 days before slaughter. Not for use in 
swine over 113.40 kilograms (250 pounds) body weight. Use as the only 
source of tiamulin. Swine being treated with tiamulin should not have 
access to feeds containing polyether ionophores (e.g., monensin, 
lasalocid, narasin, semduramicin, or salinomycin) as adverse reactions 
may occur.
