 Drug Master File (DMF) Submissions – Overview

Drug Master File (DMF) submission to the US FDA is not mandatory, as DMFs are neither formally approved nor disapproved. However, manufacturers and DMF holders often submit independent DMFs for drug substances, excipients, and packaging materials to maintain confidentiality and facilitate access to multiple applications.

To comply 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 submissions meet FDA prerequisites. A compliant DMF enables the holder to provide Letters of Access (LoA) for applications such as INDs, NDAs, and ANDAs.

X Pharma Plus possesses a highly skilled and dedicated Regulatory team specializing in FDA DMF submissions. Our team has extensive expertise in preparing, submitting, and managing DMFs for drug substances, excipients, and packaging materials in full compliance with US FDA requirements.
