06-3120. New Animal Drugs for Use in Animal Feeds; Bacitracin; Nicarbazin; Oxytetracycline and Neomycin; Penicillin  

  • Start Preamble

    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 four supplemental new animal drug applications (NADAs) filed by Phibro Animal Health. One 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. Two of the supplemental NADAs provide for the use of approved, single-ingredient Type A medicated articles containing nicarbazin and penicillin, with or without roxarsone, to formulate two-way or three-way combination drug Type C medicated feeds for broiler chickens. The fourth supplemental NADA provides for the use of approved, single-ingredient Type A medicated articles nicarbazin, bacitracin methylene disalicylate, and roxarsone to formulate three-way combination drug Type C Start Printed Page 16224medicated feeds for broiler chickens. These approvals reflect 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 March 31, 2006.

    SUPPLEMENTARY INFORMATION:

    In the Federal Register of August 8, 2003 (68 FR 47332), as corrected October 7, 2003 (68 FR 57919), as part of the Drug Efficacy Study Implementation (DESI) program, CVM announced the effective conditions of use for several drug products and use combinations listed in 21 CFR 558.15. CVM proposed to withdraw the new animal drug applications (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. Phibro Animal Health, 65 Challenger Rd., 3d Floor, Ridgefield Park, NJ 07660, filed supplements to four of its approved NADAs to revise the labeling of its products to comply with these findings of effectiveness.

    Phibro Animal Health filed a supplement to approved NADA 94-975 for NEO-TM 50/50D and NEO-TM 100/100D (oxytetracycline and neomycin sulfate) Type A medicated articles. The supplemental NADA provides 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.

    Phibro Animal Health also filed a supplement to approved NADA 98-371 for use of nicarbazin, procaine penicillin, and roxarsone single-ingredient Type A medicated articles to make three-way combination drug Type C medicated feeds. This supplemental NADA provides for the use of combination feeds containing NICARBAZIN (nicarbazin) at 90.8 to 181.6 grams per ton (g/ton), PENICILLIN G PROCAINE (procaine penicillin) at 2.4 to 50 g/ton, and 3-NITRO (roxarsone) at 22.7 to 45.4 g/ton of feed in broiler chickens as an aid in preventing outbreaks of cecal (Eimeria tenella) and intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) coccidiosis; for increased rate of weight gain and improved feed efficiency; and for improved pigmentation.

    Phibro Animal Health also filed a supplement to approved NADA 98-374 for use of nicarbazin and procaine penicillin G Type A medicated articles to formulate two-way combination drug Type C medicated feeds. This supplemental NADA provides for the use of combination feeds containing NICARBAZIN (nicarbazin) at 90.8 to 181.6 g/ton and PENICILLIN G PROCAINE (procaine penicillin) at 2.4 to 50 g/ton of feed in broiler chickens as an aid in preventing outbreaks of cecal (Eimeria tenella) and intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) coccidiosis; and for increased rate of weight gain and improved feed efficiency.

    Phibro Animal Health also filed a supplement to approved NADA 100-853 for use of nicarbazin, bacitracin methylene disalicylate, and roxarsone single-ingredient Type A medicated articles to make three-way combination drug Type C medicated feeds. This supplemental NADA provides for the use of combination feeds containing NICARBAZIN (nicarbazin) at 90.8 to 181.6 g/ton, BMD (bacitracin methylene disalicylate) at 4 to 50 g/ton, and 3-NITRO (roxarsone) at 22.7 to 45.4 g/ton of feed in broiler chickens as an aid in preventing outbreaks of cecal (Eimeria tenella) and intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) coccidiosis, and for increased rate of weight gain, improved feed efficiency, and improved pigmentation.

    The DESI evaluation is 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 and three combination drug medicated feeds.

    The supplemental NADAs are approved as of February 15, 2006, and the regulations are amended in 21 CFR 558.76, 558.460, and 558.366, and also in 21 CFR part 558 by adding new § 558.455 to reflect these approvals. Approval of these supplemental NADAs did not require review of any new safety or effectiveness data. Therefore, a freedom of information summary was not prepared.

    The agency has determined under 21 CFR 25.33(a)(2) that these actions are of a type that do 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.
