Overview

Overview

Active Substance Master File submission (ASMF submission) is not a mandatory requirement from the European Union (EU) Health Authorities, as it would be reviewed only in connection with a Marketing Authorization Application (MAA). Active substance (API) manufacturers/Active substance Master File holders can directly submit the Active Substance Master File (ASMFs) to the EU Health Authorities as per the submission procedure identified by the MAA holder.

To avoid administrative comments/rejection of MAA due to non-availability of the ASMF and to receive timely MAA approval, submission of ASMF as per the EU specific requirements (ASMF guidelines) is very critical. ASMF holder can provide Letter of Authorization (LoA) to multiple MAA holders to refer in multiple applications.
