Manufacturers and holders of drug substances, excipients, and packaging materials submit Drug Master Files (DMFs) to the US FDA to provide confidential information about the manufacturing, processing, and storage of these components. This information is used by the FDA to evaluate the safety, efficacy, and quality of the final drug product. Although DMF submissions are not mandatory for FDA approval, they are a common practice in the pharmaceutical industry to protect the confidentiality of the manufacturing processes and enable the sharing of information between multiple applications.
DMF holders need to ensure that their DMF meets the formatting requirements and contains all necessary information to comply with the Generic Drug User Fee Act (GDUFA) II and Initial Completeness Assessment (ICA) requirements of the US FDA. This includes providing detailed information about the drug substance, such as its manufacturing process, controls, specifications, and stability data, as well as information about the excipients and packaging materials.
Once a Drug master file is complete and accepted by the FDA, the DMF Holder can provide access to multiple applications, such as Investigational New Drug Applications (INDs), New Drug Applications (NDAs). Abbreviated New Drug Applications (ANDAs), and other DMFs, through a Letter of Access (LoA). The LoA provides the applicant with the right to refer to the DMF in their application without revealing its confidential information. Without an accepted DMF, it may be difficult for manufacturers to get their products approved by the FDA.
Submitting (DMF) is an Educated move
Submitting a DMF is a voluntary practice by manufacturers and DMF holders to maintain the confidentiality of the manufacturing processes and enable the sharing of information between multiple applications. It is important to note that US DMFs are neither approved nor disapproved by the FDA. Instead, the FDA conducts a completeness assessment of the DMF to ensure that it contains all the required information and meets the FDA’s formatting requirements.
Filing a Drug master file can be a complex process. And it is important to have a dedicated and experienced regulatory team to ensure compliance with the FDA requirements. Templarpharma has a team of experts with experience in DMF filing and submission. Managing the DMF for drug substances, excipients, and packaging materials to the US FDA.
