Physiologically Based Pharmacokinetic Analyses--Format and 
Content; Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance for industry entitled 
``Physiologically Based Pharmacokinetic Analyses--Format and Content.'' 
This guidance outlines the recommended format and content for a sponsor 
or applicant to submit physiologically based pharmacokinetic (PBPK) 
analyses to FDA to support applications including, but not limited to, 
investigational new drug applications (INDs), new drug applications 
(NDAs), biologics license applications (BLAs), or abbreviated new drug 
applications (ANDAs). 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 or a drug product.

DATES: The announcement of the guidance is published in the Federal 
Register on September 4, 2018.

ADDRESSES: You may submit either electronic or written comments on 
Agency guidances at any time as follows:

Electronic Submissions

attachments, except for information submitted, marked and identified, 
as confidential, if submitted as detailed in ``Instructions.''
    Instructions: All submissions received must include the Docket No. 
FDA-2016-D-3969 for ``Physiologically Based Pharmacokinetic Analyses--
Format and Content.'' Received comments will be placed in the docket 
and, except for those submitted as ``Confidential Submissions,'' 
publicly viewable at https://www.regulations.gov or at the Dockets 
Management Staff between 9 a.m. and 4 p.m., Monday through Friday.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a final 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 mechanistically 
describe the pharmacokinetic behaviors of a drug or drug product. 
Throughout a drug's life cycle, PBPK model predictions can be used to 
support decisions on whether, when, and how to conduct certain clinical 
pharmacology studies, and to support dosing recommendations in product 
labeling. Because of the lack of regulatory guidance, the format and 
content of PBPK analysis reports that are submitted to FDA vary 
significantly. The goal of this guidance is to standardize the content 
and format of these reports to facilitate FDA's efficient assessment, 
consistent application, and timely decision making during regulatory 
review.
    This guidance outlines the recommended format and content for a 
sponsor or applicant to submit PBPK analyses to FDA to support 
applications including, but not limited to, INDs, NDAs, BLAs, and 
ANDAs. 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 or a drug 
product.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on ``Physiologically Based Pharmacokinetic 
Analyses--Format and Content.'' 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. This guidance is not subject to Executive 
Order 12866.

II. Paperwork Reduction Act of 1995

    This 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.

III. Electronic Access

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