◆ Authorisation of Generic Drugs in the USA: Requirements on APIs Stability Data for US Drug Master Files(19-Sep-13 ECA)

According to the new Generic Drug User Fee Act (GDUFA) for the marketing authorisation of generic drugs in the USA, the Drug Master File (TypeII) for APIs must undergo a completeness assessment. The statements laid down in the Q&A document regarding the stability data of the API required in a DMF are explicit: in addition to the stability protocol and commitments, data demonstrating the beginning of stability studies have to be provided. The initial and one additional time point for the accelerated studies and long-term studies are sufficient. Yet, the DMF holder should provide amending data to keep the DMF as up-to-date as possible. This is the only way to ensure the successful completeness assessment by the reviewer in the Office of Generic Drugs (OGD) of the FDA.
