Drug Master File (DMF) Submissions

Drug Master File (DMF) Submissions - Overview

Drug Master File Submission (DMF submission) is not mandatory for the US FDA, as DMFs are neither approved nor disapproved. However, to maintain confidentiality in multiple DMFs, manufacturers/DMF holders file independent DMF submissions for drug substances/excipients/packaging materials.

To be compliant with the Generic Drug User Fee Act (GDUFA) II and Initial Completeness Assessment (ICA) requirements of the US FDA, DMF holders must ensure that their DMF is compliant with the FDA prerequisites. It is critical to get approval for the DMF application as it will enable the DMF holder to provide access to multiple applications such as IND/NDA/ANDA through a Letter of Access (LoA).
