Biopharmaceutics Classification System-Based Biowaivers; International Council for Harmonisation; Draft Guidance for Industry; Availability

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled "Biopharmaceutics Classification System-Based Biowaivers." The draft guidance was prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. The draft guidance will provide recommendations to support the biopharmaceutics classification of drug substances and the Biopharmaceutics Classification System (BCS)-based waiver of in vivo bioequivalence (BE) studies for drug products. In vivo BE studies are needed to demonstrate lack of impact of significant formulation changes on a drug's bioavailability during its development, for post-approval line extensions, and when developing a generic product. Utilizing the critical properties of the drug substance and the drug product, and applying the BCS framework, assurance of in vivo BE findings can be obtained using extensive in vitro studies. The draft guidance is intended to avoid unnecessary human BE trials based on extensive in vitro characterization of the drug substance and drug product properties.
