2014-02617. Zoetis Inc., et al.; Withdrawal of Approval of New Animal Drug Applications for Combination Drug Medicated Feeds Containing an Arsenical Drug

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule; technical amendments.

SUMMARY:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect the withdrawal of approval of 69 new animal drug applications (NADAs) and 22 abbreviated new animal drug applications (ANADAs) for use of arsanilic acid, carbarsone, or roxarsone Type A medicated articles to manufacture combination drug Type B and Type C medicated feeds. This action is being taken at the sponsor's request because the products are no longer manufactured or marketed. FDA is also amending the animal drug regulations to remove entries describing conditions of use for combination drug medicated feeds for which no NADA is approved. This action is being taken to improve the accuracy of the regulations.

DATES:

This rule is effective March 10, 2014.

SUPPLEMENTARY INFORMATION:

Recently, the Agency provided notice of the withdrawal of approval of NADAs for Type A medicated articles containing arsanilic acid, carbarsone, and roxarsone and revoked applicable regulations for their conditions of use to manufacture single-ingredient medicated feeds in 21 CFR part 558 New Animal Drugs For Use in Animal Feeds (78 FR 70062, Nov. 22, 2013; 78 FR 69992, Nov. 22, 2013; 78 FR 70566, Nov. 26, 2013; 78 FR 70496, Nov. 26, 2013).

Subsequently, the following six sponsors of NADAs and ANADAs permitting use of arsanilic acid, carbarsone, or roxarsone Type A medicated articles to manufacture combination drug Type B and Type C medicated feeds requested that FDA withdraw approval of their applications because these combination medicated feeds are no longer manufactured or marketed.

• Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285 has requested that FDA withdraw approval of the following four NADAs:

• Cross Vetpharm Group Ltd., Broomhill Rd., Tallaght, Dublin 24, Ireland, has requested that FDA withdraw approval of the following three NADAs:

NADA	Ingredient new animal drugs
038-241	PRO-GEN (arsanilic acid)/ERYTHRO (erythromycin)/zoalene.
038-242	PRO-GEN (arsanilic acid)/ERYTHRO (erythromycin)/amprolium + ethopabate.

• Pennfield Oil Co., 14040 Industrial Rd., Omaha, NE 68144 has requested that FDA withdraw approval of the following ANADA:

NADA	Ingredient new animal drugs
200-355	3-NITRO (roxarsone)/PENNCHLOR (chlortetracycline)/BIO-COX (salinomycin).

Elsewhere in this issue of the Federal Register, FDA gave notice that approval of these NADAs and ANADAs, and all supplements and amendments thereto, is withdrawn, effective March 10, 2014. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these voluntary withdrawals of approval.

In addition, FDA has noticed that certain sections in part 558 contain entries describing conditions of use for combination drug medicated feeds for which no NADA is approved. These errors were introduced by the Agency during the 1976 recodification of certain food additive regulations (41 FR 10984, March 15, 1976). That rule did not identify whether particular regulations were the subject of an approved NADA and consequently resulted in codification of certain conditions of use for which there is no approved NADA. At this time, the Agency is amending the regulations to remove entries that describe conditions of use for combination drug medicated feeds for which no NADA is approved. This action is being taken to improve the accuracy of the regulations.

This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability.” Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
