Overview
An Active Substance Master File (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 (Active Pharmaceutical Ingredient (API)) manufacturers/Active Substance Master File holders can directly submit the 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 the ASMF as per the EU specific requirements (ASMF guidelines) is critical. The ASMF holder can provide a Letter of Authorization (LoA) to multiple MAA holders as a reference in multiple applications.
