SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Maximal Usage Trials for Topical Active Ingredients Being 
Considered for Inclusion in an Over-the-Counter Monograph: Study 
Elements and Considerations.'' This draft guidance addresses the 
current thinking of FDA on the conduct of in vivo absorption trials for 
topical active ingredients that are under consideration for inclusion 
in an OTC monograph. A Maximal Usage Trial (MUsT) is a standard 
approach to assessing the in vivo bioavailability of topical drug 
products. The methodology described in this draft guidance adapts MUsT 
principles for active ingredients being considered for inclusion in an 
OTC monograph. Because information from a MUsT can help identify the 
potential for systemic exposure to a topically applied active 
ingredient, such information can help inform an FDA determination of 
whether additional safety data are needed to support a finding that an 
OTC drug containing that active ingredient is generally recognized as 
safe and effective for its intended use.
    This draft guidance was written in response to comments submitted 
to Docket No. FDA-2015-D-4021 for the draft guidance entitled ``Over-
the-Counter Sunscreens: Safety and Effectiveness Data'' (80 FR 72975, 
November 23, 2015) and the final guidance that replaced it, entitled 
``Nonprescription Sunscreen Drug Products--Safety and Effectiveness 
Data'' (81 FR 84594, November 23, 2016), requesting that FDA provide 
further guidance and details on the MUsT. It provides additional 
information on the study elements, data analysis, and considerations 
when designing a MUsT for a topical active ingredient being considered 
for inclusion in an OTC monograph.
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 ``Maximal 
Usage Trials for Topical Active Ingredients Being Considered for 
Inclusion in an Over-the-Counter Monograph: Study Elements and 
Considerations.'' 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

[[Page 23920]]

the requirements of the applicable statutes and regulations. This 
guidance is not subject to Executive Order 12866.

II. Paperwork Reduction Act of 1995

    This draft guidance contains collections of information that are 
exempt from the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-
3520). Section 586D(a)(1)(C) of the Federal Food, Drug, and Cosmetic 
Act (21 U.S.C. 360fff-4(a)(1)(C)) as amended by the Sunscreen 
Innovation Act states that the PRA shall not apply to collections of 
information made for purposes of guidance under that subsection.

III. Electronic Access

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