SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a revised draft guidance for industry entitled “Bioequivalence Studies With Pharmacokinetic Endpoints for Drugs Submitted Under an ANDA.” The revised draft guidance supersedes the draft guidance “Bioequivalence Studies With Pharmacokinetic Endpoints for Drugs Submitted Under an ANDA,” which was announced in the Federal Register on December 5, 2013 (78 FR 73199). FDA received nine comments on the draft guidance, which were considered before publication of this revised draft guidance.

This revised draft guidance provides recommendations to applicants planning to include BE information in ANDAs and ANDA supplements. In addition, this guidance describes how to meet the BE requirements set forth in the FD&C Act and FDA regulations. This guidance is generally applicable to dosage forms intended for oral administration and to non-orally administered drug products in which reliance on systemic exposure measures is suitable for documenting BE (e.g., transdermal delivery systems and certain rectal and nasal drug products). This guidance will also be useful to applicants planning BE studies intended to be conducted during the post-approval period for changes to a drug product approved in an ANDA. FDA recommends that applicants consult this revised draft guidance, in conjunction with any relevant product-specific guidances for industry, when considering the appropriate BE study and/or other studies for a proposed drug product.

This revised draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The revised draft guidance, when finalized, will represent the current thinking of FDA on “Bioequivalence Studies With Pharmacokinetic Endpoints for Drugs Submitted Under an ANDA.” 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. Paperwork Reduction Act of 1995

FDA tentatively concludes that this draft guidance contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.

III. Electronic Access

Persons with access to the internet may obtain the draft guidance at https://www.fda.gov/drugs/guidance-compliance-regulatory-information/guidances-drugs,, https://www.fda.gov/regulatory-information/search-fda-guidance-documents,, or https://www.regulations.gov.
