Population Pharmacokinetics; Revised Draft Guidance for Industry; 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the availability of a revised draft guidance for industry entitled 
``Population Pharmacokinetics.'' This revised draft guidance assists 
sponsors in the application of population pharmacokinetics (population 
PK) during the drug development process to inform drug use and includes 
FDA's current thinking on the data and model requirements for 
population PK analyses submitted as part of new drug applications 
(NDAs) and biologic license applications (BLAs). The revised draft 
guidance also provides expectations regarding the format and content of 
the population PK report as well as any labeling recommendations 
resulting from such analyses.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by September 10, 2019.

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a revised draft guidance for 
industry entitled ``Population Pharmacokinetics.'' Population PK 
analyses can quantify the impact of intrinsic and extrinsic patient 
factors on the exposure of a drug. In conjunction with supporting 
exposure-response data, population PK data can be used to identify 
patient factors that result in a clinically significant change in drug 
exposure and inform the proper use of drugs. Since FDA announced the 
publication of the original population PK guidance in 1999, the number 
of applications relevant for population PK analysis has increased, and 
the sophistication and reliability of population PK analysis methods 
have improved. This revised draft guidance will replace the 1999 FDA 
guidance for industry of the same name.
    This revised draft guidance assists sponsors of NDAs and BLAs in 
the conduct of population PK analysis. Specifically, the revised draft 
guidance includes a description of the types of scientific and 
regulatory questions appropriate for population PK analysis and 
outlines FDA's recommendations for data analysis and modeling. 
Recommendations on the format and content of population PK reports 
submitted to FDA as well as any labeling statements informed by the 
results of these analyses are also provided.
    This revised 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 
``Population Pharmacokinetics.'' 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 revised draft guidance refers to previously approved 
collections of information that 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 collections of information in 21 CFR parts 
312 and 314 have been approved under OMB control numbers 0910-0014 and 
0910-0001, respectively. The collection of information in 21 CFR 201.56 
and 201.57 has been approved under OMB control number 0910-0572.

III. Electronic Access

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