SUPPLEMENTARY INFORMATION: 

I. Background

    In the Federal Register of June 11, 2010 (75 FR 33311; FDA-2007-D-
0433), FDA announced the availability of a guidance for industry 
entitled ``Bioequivalence Recommendations for Specific Products,'' 
which explained the process that would be used to make product-specific 
bioequivalence (BE) recommendations available to the public on FDA's 
Web site at http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm. As 
described in that guidance, FDA adopted this process as a means to 
develop and disseminate product-specific BE recommendations and provide 
a meaningful opportunity for the public to consider and comment on 
those recommendations. This notice announces the availability of draft 
BE recommendations for metronidazole vaginal gel.
    New drug application 020208 for MetroGel-Vaginal (metronidazole) 
vaginal gel, 0.75%, was initially approved by FDA in August 1992. On 
October 31, 2006, FDA approved ANDA 077264 for a generic version of 
MetroGel-Vaginal 0.75% (metronidazole). FDA is now issuing a draft 
guidance for industry on BE recommendations for generic metronidazole 
vaginal gel (Draft Metronidazole Vaginal Gel BE Recommendations).
    In March 2006, Foley & Lardner LLP (the petitioner) submitted a 
citizen petition requesting that FDA require that any ANDA referencing 
Metro-Gel Vaginal meet certain conditions, including conditions related 
to demonstrating BE (Docket No. FDA-2006-P-0080). FDA is reviewing the 
issues raised in the petition. FDA will consider any comments on the 
Draft Metronidazole Vaginal Gel BE Recommendations in responding to the 
citizen petition.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the Agency's current thinking on the design 
of BE studies to support ANDAs for metronidazole vaginal gel. It does 
not create or confer any rights for or on any person and does not 
operate to bind FDA or the public. An alternative approach may be used 
if such approach satisfies the requirements of the applicable statutes 
and regulations.

II. Comments

    Interested persons may submit either written comments regarding 
this document to the Division of Dockets Management (see ADDRESSES) or 
electronic comments to http://www.regulations.gov. It is only necessary 
to send one set of comments. Identify comments with the docket number 
found in brackets in the heading of this document. Received comments 
may be seen in the Division of Dockets Management between 9 a.m. and 4 
p.m., Monday through Friday, and will be posted to the docket at http://www.regulations.gov.
