SUPPLEMENTARY INFORMATION: 

I. Background

    In the Federal Register of June 11, 2010 (75 FR 33311), FDA 
announced the availability of a guidance for industry, ``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 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 
revised draft BE recommendations for cyclosporine ophthalmic emulsion.
    FDA initially approved new drug application 050790 for RESTASIS 
(cyclosporine ophthalmic emulsion), 0.05% in December 2002. There are 
no approved ANDAs for this product. In June 2013, we issued a draft 
guidance for industry on BE recommendations for generic cyclosporine 
ophthalmic emulsion.
    Allergan, Inc., manufacturer of the reference listed drug, 
RESTASIS, submitted a citizen petition in February 2014 challenging the 
Agency's initial BE recommendations for generic cyclosporine ophthalmic 
emulsion. We responded to that petition on November 20, 2014 (Docket 
No. FDA-2014-P-0304). The following month, Allergan submitted a second 
citizen petition challenging the Agency's initial BE recommendations. 
In April 2015, FDA received a third citizen petition on its initial BE 
recommendations from Physical Pharmaceutica LLC. FDA has reviewed the 
issues raised by Allergan and Physical Pharmaceutica and is responding 
to their petitions (Docket Nos. FDA-2015-P-0065 and FDA-2015-P-1404).
    In addition, we are now issuing a revised draft guidance for 
industry on BE recommendations for generic cyclosporine ophthalmic 
emulsion (``Draft Guidance on Cyclosporine'').
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 cyclosporine ophthalmic emulsion. 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.
