21 CFR Part 558

[Docket No. FDA-2009-N-0665]

 
New Animal Drugs for Use in Animal Feeds; Oxytetracycline; 
Neomycin

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 Pennfield Oil Co. The supplemental NADA 
provides for the use of fixed-combination Type A medicated articles 
containing oxytetracycline and neomycin sulfate to formulate two-way, 
fixed-combination drug Type B and Type C medicated feeds for chickens, 
turkeys, swine, cattle, and sheep. This approval reflects FDA's 
effectiveness conclusions which relied on the National Academy of 
Sciences/National Research Council (NAS/NRC) Drug Efficacy Study 
Group's evaluation of the effectiveness of these drugs when used in 
animal feed as single ingredients.

DATES: This rule is effective August 13, 2009.

FOR FURTHER INFORMATION CONTACT: Harlan Howard, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 240-276-8111, e-mail: harlan.howard@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, CVM announced 
the effective conditions of use for several drug products and use 
combinations that were listed in Sec.  558.15 (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, Pennfield Oil Co., (Pennfield) 14040 
Industrial Rd., Omaha, NE 68144, filed a hearing request for its 
approved NADA 138-939 NEO-OXY 50/50, NEO-OXY 100/100, and NEO-OXY 100/
100 MR (oxytetracycline and neomycin sulfate). These products are two-
way, fixed-combination Type A medicated articles used to make two-way 
combination drug Type C medicated feeds. Pennfield subsequently filed a 
supplement to NADA 138-939 to revise the labeling of these products to 
comply with these findings of effectiveness. The supplemental NADA 
provided for use of these fixed-combination Type A medicated articles 
to formulate two-way, fixed-combination drug Type B and Type C 
medicated feeds containing oxytetracycline and neomycin sulfate, in a 
1:1 ratio, for several production and therapeutic indications in 
chickens, turkeys, swine, cattle, and sheep. The supplemental NADA is 
approved as of July 2, 2009, and the regulations are amended in 21 CFR 
558.455 to reflect the approval. Pennfield has since withdrawn its 
hearing request for NDA 138-939.
    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 Policy Letter Eight, August 21, 1991 (56 FR 
41561). Accordingly, sponsors may now obtain approval of abbreviated 
NADAs for this fixed combination Type A medicated article.
    The agency has determined under 21 CFR 25.33 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

[[Page 40724]]

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.
