[Docket Nos. 80N-0012 and 84N-0067; DESI 10826]


Drug Efficacy Study Implementation; Certain Topical Anti-
Infective Drug Products; Withdrawal of Approval of New Drug 
Applications

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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


SUMMARY: The Food and Drug Administration (FDA) is withdrawing approval 
of pertinent parts of the new drug applications (NDA's) for cream and 
ointment products containing neomycin sulfate and gramicidin in 
addition to nystatin and triamcinolone acetonide. There is a lack of 
substantial evidence that the products as originally formulated are 
effective in the treatment of various dermatoses and as anti-infective 
agents for which they are labeled. Both products have been reformulated 
to eliminate neomycin sulfate and gramicidin, and FDA has approved the 
reformulated products as safe and effective.

EFECTIVE DATE:  September 16, 1996.

ADDRESSES: Requests for guidance on the applicability of this notice to 
a specific product should be identified with the Drug Efficacy Study 
Implementation (DESI) number 10826 and directed to the Division of 
Prescription Drug Compliance and Surveillance (HFD-330), Center for 
Drug Evaluation and Research, Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855.

FOR FURTHER INFORMATION CONTACT: Christine F. Rogers, Center for Drug 
Evaluation and Research (HFD-366), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-2041.

SUPPLEMENTARY INFORMATION: In a notice of opportunity for a hearing 
published in the Federal Register of September 25, 1981 (46 FR 47408), 
the Director of the Bureau of Drugs (now the Center for Drug Evaluation 
and Research) proposed to withdraw approval of NDA's for certain 
topical anti-infective drug products. The proposal was based on the 
lack of substantial evidence of effectiveness as required by section 
505(e) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 
355(e)) and 21 CFR 314.126 (previously 21 CFR 314.111(a)(5)). In 
response to that notice, requests for a hearing were filed for the 
following NDA's:
    1. NDA's 60-572 and 60-576; Mycolog Ointment and Cream, 
respectively, both containing nystatin (100,000 units per gram (g)), 
triamcinolone acetonide (1.0 milligram (mg)/g), neomycin sulfate (2.5 
mg/g), and gramicidin (0.25 mg/g); now held by Apothecon, a division of 
Bristol-Myers Squibb, P.O. Box 4500, Princeton, NJ 08543-4500.
    2. NDA's 61-954 and 62-045; Myco Triacet Cream and Ointment, 
respectively, containing nystatin, neomycin sulfate, gramicidin, and 
triamcinolone acetonide; held by Lemmon Co., 650 Cathill Rd., 
Sellersville, PA 18960.
    3. NDA's 62-135 and 62-136; Nystatin-Neomycin Sulfate-Gramicidin-
Triamcinolone Acetonide Ointment and Cream, respectively; held by E. 
Fougera and Co. (formerly Byk Pharmaceutical Group), a division of 
Altana, Inc., 60 Baylis Rd., Melville, NY 11747.
    4. NDA's 62-186 and 62-280; Nystatin-Neomycin Sulfate-Gramicidin-
Triamcinolone Acetonide Cream and Ointment, respectively; held by Clay-

Park Labs, Inc. (formerly Clay Park Laboratories), 1700 Bathgate Ave., 
Bathgate Industrial Park, Bronx, NY 10457.
    NMC Laboratories, 70-36 83d St., Glendale, NY 11385, filed a 
hearing request without reference to a particular product.
    In a document published in the Federal Register of April 17, 1985 
(50 FR 15227), FDA announced conditions for approval and marketing of 
reformulations of both the cream and ointment products that omit 
neomycin sulfate and gramicidin. FDA subsequently approved supplemental 
NDA's providing for reformulation of all the products listed above.
    The drug manufacturers listed above have since withdrawn their 
hearing requests. Accordingly, FDA is now withdrawing approval of those 
parts of the NDA's listed above pertaining to the products containing 
neomycin sulfate and gramicidin.
    Antibiotic drug monographs for nystatin-neomycin sulfate-
gramicidin-triamcinolone acetonide ointment and cream products are 
cited in 21 CFR 449.550c and 449.550e, respectively. These monographs 
will be modified in a future  Federal Register notice, if necessary. In 
accord with the plans announced by President Clinton on March 4, 1995, 
regarding reform of the Federal regulatory system as part of the 
Administration's ``Reinventing Government'' initiative, the agency has 
initiated the consideration of legislation that would eliminate the 
need for publication of antibiotic monographs.
    Any drug product that is identical, related, or similar to the 
products listed above and is not the subject of an approved NDA is 
covered by the NDA's reviewed and is subject to this notice (21 CFR 
310.6). Any person who wishes to determine whether a specific product 
is covered by this notice should write to the Division of Prescription 
Drug Compliance and Surveillance (address above).
    The Director of the Center for Drug Evaluation and Research, under 
section 505(e) of the act and under authority delegated to her (21 CFR 
5.82), finds, on the basis of new information before her with respect 
to the cream and ointment products containing neomycin sulfate and 
gramicidin, evaluated together with the evidence available to her when 
the applications were approved, that there is a lack of substantial 
evidence that the products will have the effect they purport or are 
represented to have under the conditions of use prescribed, 
recommended, or suggested in their labeling.
    Therefore, pursuant to the foregoing finding, approval of those 
parts of NDA 60-576 and NDA 60-572 that provide for Mycolog Cream and 
Ointment, respectively; those parts of NDA 61-954 and NDA 62-045 that 
provide for Myco Triacet Cream and Ointment, respectively; those parts 
of NDA 62-135 and NDA 62-136 that provide for the cream and ointment, 
respectively; and those parts of NDA 62-l86 and NDA 62-280 that provide 
for the cream and ointment, respectively, containing neomycin sulfate 
and gramicidin, and all the amendments and supplements for these 
products, is withdrawn effective September 16, 1996. Shipment in 
interstate commerce of the products above or any identical, related, or 
similar product that is not the subject of an approved new drug 
application will be unlawful as of that effective date.

    Dated: June 28, 1996.
Janet Woodcock,
Director, Center for Drug Evaluation and Research.
