Active Substance Master File (ASMF) Submissions – An Overview

An Active Substance Master File (ASMF), formerly known as European Drug Master File (EDMF) submission, is not a mandatory requirement for the European Union (EU) Health Authorities (HAs), as it is reviewed only in connection with a Marketing Authorization Application (MAA). Active substance (Active Pharmaceutical Ingredient [API]) manufacturers/Active Substance Master File holders can directly submit the ASMFs to the EU HAs as per the submission procedure identified by the MAA holder.

To avoid administrative comments/rejection of an MAA due to the non-availability of the ASMF and to receive timely MAA approval, submission of the Active Substance Master File as per the EU-specific requirements (ASMF guidelines) is crucial. The ASMF holder can provide a Letter of Authorization (LoA) to multiple MAA holders as a reference in multiple applications.
