SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Physiologically Based Pharmacokinetic Analyses--Format and 
Content.'' A PBPK analysis uses models and simulations that combine 
physiology, population, and drug characteristics to describe the 
pharmacokinetics and/or pharmacodynamics of that particular drug in 
humans. Throughout a drug's life cycle, PBPK analyses can be used to 
support decisions on whether, when, and how to conduct certain clinical 
pharmacology studies, inform dosing recommendations, and enable 
prescription drug labeling. Currently, the format and content of PBPK 
analyses that are submitted to FDA vary significantly across drug 
developers. Standardizing the content and format of the PBPK analyses 
can facilitate FDA's efficient assessment, consistent application, and 
timely decision making during regulatory review. This guidance 
recommends including the following five sections in a PBPK study 
report: (1) Executive Summary, (2) Materials and Methods, (3) Results, 
(4) Discussion, and (5) Appendices. This guidance does not address 
methodological considerations and best practices for the conduct of 
PBPK modeling and simulation, or the appropriateness of PBPK analyses 
for a particular drug.
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 format and 
content of PBPK analyses. 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    Persons with access to the Internet may obtain the draft guidance 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 
https://www.regulations.gov.

III. Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
are subject to review by the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The 
collection of information in 21 CFR 314.50(d) has been approved under 
OMB control number 0910-0001.
