SUPPLEMENTARY INFORMATION:

I. Background

    In the Federal Register of June 11, 2010 (75 FR 33311), 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 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 to develop 
and disseminate product-specific BE recommendations and to provide a 
meaningful opportunity for the public to consider and comment on those 
recommendations. This notice announces the availability of draft BE 
recommendations for generic fidaxomicin tablets.
    FDA initially approved new drug application (NDA) 201699 for 
DIFICID (fidaxomicin) in May 2011. Currently, there are no approved 
ANDAs for this product. We are now issuing a draft guidance for 
industry on BE recommendations for generic fidaxomicin tablets (``Draft 
Guidance on Fidaxomicin'').
    On May 6, 2015, Cubist Pharmaceuticals, Inc. submitted a

[[Page 57922]]

citizen petition requesting that ``FDA impose scientifically-
appropriate standards for demonstrating BE for ANDAs and 505(b)(2) new 
drug applications'' citing to DIFICID as the reference listed drug. FDA 
has reviewed the issues raised in the citizen petition and is 
responding to the citizen petition (Docket No. FDA-2015-P-1595, 
available at http://www.regulations.gov).
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 current thinking of FDA on the design of 
BE studies to support ANDAs for fidaxomicin tablets. It does not 
establish any rights for any person and is not binding on FDA or the 
public. You can use an alternative approach if it satisfies the 
requirements of the applicable statutes and regulations.

II. Electronic Access

    Persons with access to the Internet may obtain the draft guidance 
at either http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm or http://www.regulations.gov.

    Dated: August 18, 2016.
Jeremy Sharp,
Deputy Commissioner for Policy, Planning, Legislation, and Analysis.
