Abstract

The Global Bioequivalence Harmonization Initiative (GBHI) was launched by the Network on Bioavailability and Biopharmaceutics (BABP) under the auspices of European Federation for Pharmaceutical Sciences (EUFEPS) several years ago. Since 2015, EUFEPS in collaboration with the American Association of Pharmaceutical Scientists (AAPS) has organized three international conferences to support global harmonization of regulatory requirements for bioequivalence (BE) assessment. These conferences provided an open forum for pharmaceutical scientists from academia, industry and regulatory agencies to discuss various BE topics at issue. The current report summarizes the discussion of BE issues at the 2nd GBHI conference held in 2016, Rockville, USA. Three important BE topics were discussed at the meeting: (a) prodrugs and compounds with pre-systemic extraction, (b) scaling procedures and two-stage designs, and (c) exclusion of pharmacokinetic data in BE assessment. The presentations and discussions of these issues have enhanced the mutual understanding of scientific background for BE evaluation and further facilitated harmonization of regulatory approaches for establishing BE of multisource drug products.
