21 CFR Part 558

[Docket No. FDA-2015-N-0002]


New Animal Drugs for Use in Animal Feeds; Bacitracin 
Methylenedisalicylate

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 Pharmgate LLC for the use of a Type A 
medicated article containing bacitracin methylenedisalicylate to 
manufacture Type B and Type C medicated feeds for chickens, turkeys, 
pheasants, quail, and feedlot cattle. This supplemental approval 
reflects FDA's effectiveness conclusions that relied on the National 
Academy of Sciences/National Research Council Drug Efficacy Study 
Group's evaluation of the effectiveness of this drug as well 
indications for use not subject to this review.

DATES: This rule is effective December 22, 2015.

FOR FURTHER INFORMATION CONTACT: Matthew Lucia, Center for Veterinary 
Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 240-402-0589, email: matthew.lucia@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: In the Federal Register of August 8, 2003 
(68 FR 47332), as corrected October 7, 2003 (68 FR 57911), as part of 
the Drug Efficacy Study Implementation (DESI) program, the Center for 
Veterinary Medicine (CVM) announced the effective conditions of use for 
several drug products and use combinations that were listed in 21 CFR 
558.15. CVM proposed to withdraw the NADAs for those products or use 
combinations lacking substantial evidence of effectiveness following a 
90-day opportunity to supplement the NADAs with labeling conforming to 
the relevant findings of effectiveness.
    In response to that notice of opportunity for a hearing (NOOH), 
Pennfield Oil Co. (Pennfield), 14040 Industrial Rd., Omaha, NE 68144, 
filed a hearing request for its approved, non-DESI finalized NADA 141-
137 for a bacitracin methylenedisalicylate Type A medicated article.
    In March 2015, Pennfield transferred sponsorship of NADA 141-137 to 
Pharmgate LLC, 1015 Ashes Dr., Suite 102, Wilmington, NC 28405 
(Pharmgate) (80 FR 13226, March 13, 2015). Subsequently, Pharmgate 
filed a supplement to NADA 141-137 for PENNITRACIN MD 50G (bacitracin 
Type A medicated article) with labeling conforming to the findings of 
effectiveness in the 2003 NOOH. In addition, the submitted labeling 
included indications for use approved by FDA that were not subject to 
DESI findings of effectiveness (34 FR 7906, May 20, 1969).
    The supplemental NADA provides for use of a Type A medicated 
article containing bacitracin methylenedisalicylate to manufacture Type 
B and Type C medicated feeds for several production and therapeutic 
indications in broiler and replacement chickens, growing turkeys, 
growing pheasants, growing quail, and beef steers and heifers fed in 
confinement for slaughter. The supplemental NADA is approved as of 
October 6, 2015, and the regulations are amended in 21 CFR 558.76 to 
reflect the approval. Pharmgate, as successor to Pennfield, has since 
withdrawn the hearing request for NADA 141-137.
    Approval of this supplemental NADA did not require review of any 
new safety or effectiveness data. Therefore, a freedom of information 
summary was not prepared.
    The DESI evaluation was concerned only with the effectiveness of 
the drug products and use combinations. Nothing in this document 
constitutes a bar to further proceedings with respect to questions of 
safety of the subject drugs in treated animals or of the drugs or their 
metabolites in food products derived from treated animals.
    Products that comply with FDA's findings of effectiveness are 
eligible for copying, as described in the ``Generic Animal Drug and 
Patent Term Restoration Act; Eighth Policy Letter,'' August 21, 1991 
(56 FR 41561). Accordingly, sponsors may now obtain approval of 
abbreviated NADAs for this Type A medicated article.
    The Agency has determined under 21 CFR 25.33(a)(1) 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.
    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.

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:
