New Revised Bioequivalence Guidance Clarifies Requirements
FDA issued a newly revised Draft Guidance entitled Bioequivalence Studies with Pharmacokinetic Endpoints for Drug Submitted Under an ANDA. The new Guidance document is specific to abbreviated new drug applications (ANDAs) and combines part of two previous guidance documents on general bioequivalence (BE) and BE for fed studies for ANDAs. The document does not address bioavailability (BA) or BE for investigational new drug applications (INDs) or for studies required to support BE for new drug applications (NDAs).
