Food and Drug Administration, HHS.
Notice of availability.
The Food and Drug Administration (FDA or Agency) is announcing the availability of a revised draft guidance for industry entitled “Population Pharmacokinetics.” This revised draft guidance assists sponsors in the application of population pharmacokinetics (population PK) during the drug development process to inform drug use and includes FDA's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 The revised draft guidance also provides expectations regarding the format and content of the population PK report as well as any labeling recommendations resulting from such analyses.
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comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance, submit either electronic or written comments on the draft guidance by September 10, 2019.

FDA is announcing the availability of a revised draft guidance for industry entitled “Population Pharmacokinetics.”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 This revised draft guidance will replace the 1999 FDA guidance for industry of the same name.
This revised draft guidance assists sponsors of NDAs and BLAs in the conduct of population PK analysis. Specifically, the revised draft guidance includes a description of the types of scientific and regulatory questions appropriate for population PK analysis and outlines FDA's recommendations for data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This revised draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Population Pharmacokinetics.”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.
