A Complete Guide to Drug Master Files (DMFs): Submission Tips and Best Practices

A Drug Master File (DMF) is an essential document that contains detailed information about the facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more drugs. This guide will walk you through the complexities of DMFs, their types, submission formats, and how Celegence can assist with AI-enabled technology and services to streamline the process.

FDA Drug Master File List

The FDA maintains a comprehensive list of DMFs, which is publicly accessible and regularly updated. This list includes the DMF number, type, holder, and subject. Understanding how to navigate and interpret this list is crucial for ensuring compliance and leveraging existing data for regulatory submissions. With Celegence’s AI-powered data extraction, navigating this list becomes even more efficient, reducing manual effort and increasing accuracy.

DMF – Drug Master File

A DMF is a valuable tool for protecting proprietary information while complying with regulatory requirements. It allows manufacturers to submit confidential and detailed information about the DMF without disclosing it to the drug product applicants. The FDA reviews the DMF to support the approval of the drug product applications. Celegence offers comprehensive regulatory affairs submission services in both eCTD and non-eCTD formats, backed by an experienced regulatory team, ensuring that your DMF submissions are of the highest quality and meet all regulatory standards.

Types of Drug Master File

There are five types of DMFs, each serving a different purpose:

  1. Type I: Manufacturing Site, Facilities, Operating Procedures, and Personnel
  2. Type II: Drug Substance, Drug Substance Intermediate, and Material Used in Their Preparation, or Drug Product
  3. Type III: Packaging Material
  4. Type IV: Excipient, Colorant, Flavor, Essence, or Material Used in Their Preparation
  5. Type V: FDA Accepted Reference Information

Understanding these types is crucial for correctly categorizing your DMF. Celegence can help you get the job done with experts swiftly, ensuring your submissions are right first time and reducing the cost of compliance by 10% each year.

Drug Master File Guidance

The FDA provides extensive guidance on preparing and submitting DMFs. This guidance outlines the content and format requirements, helping manufacturers ensure their submissions meet regulatory standards. Key guidance documents include:

With our groundbreaking AI/technology, Celegence streamlines the collaborative Publishing &Submission process, ensuring improved quality and consistency with >95% accuracy over manual processes.

Drug Master File Europe

In Europe, the DMF is known as the Active Substance Master File (ASMF) which is comparable to FDA DMF Type II and Type IV. Additionally, specific procedures exist for electronic submissions and other types of master files:

  • Active Substance Master File (ASMF): The ASMF procedure allows the active substance manufacturer to protect their intellectual property by submitting confidential data directly to the competent authorities.
  • Electronic Submissions for CEP Applications (EDQM): The European Directorate for the Quality of Medicines & HealthCare (EDQM) oversees the Certification of Suitability (CEP) system, which includes electronic submission procedures to streamline the process.
  • Plasma Master File (PSMF): The PSMF is a comprehensive document required for the use of human plasma in the manufacturing of medicinal products. It includes detailed information about plasma collection and testing, ensuring the safety and quality of plasma-derived products.

Celegence’s AI and technology enable us to cut time in half on compliance, ensuring your submissions are handled efficiently and effectively, meeting all regional and global standards.

Drug Master File Sample

A well-prepared DMF sample can serve as a valuable reference for new submissions. It typically includes sections on:

  • General Information: Description of the manufacturing site, facilities, and equipment.
  • Manufacturing Process and Controls: Detailed processes and controls for the drug substance or product.
  • Characterization: Data supporting the characterization of the drug substance or product.
  • Stability: Stability data to support the shelf life of the drug substance or product.

Celegence’s document management system efficiently manages and tracks all DMF-related documents, ensuring a seamless submission process and up to 4x efficiency gains on the P&S process compared to our competitors.

Drug Master File Format

The format of a DMF is crucial for its acceptance by regulatory authorities. The Common Technical Document (CTD) format is widely used, which includes:

  • Module 2: Quality overall summary.
  • Module 3: Quality (pharmaceutical documentation).
  • Module 4: Nonclinical study reports.
  • Module 5: Clinical study reports.

Celegence ensures that your DMF is organized according to the latest standards, providing first-time right submissions and reducing turnaround times, even when urgent requests arise. The DMFs includes mainly Module 3 of CTD format.

eCTD Drug Master File

The Electronic Common Technical Document (eCTD) is the standard format for submitting DMFs electronically. It ensures a harmonized submission process across different regions, improving efficiency and reducing the risk of errors. The eCTD format facilitates easier navigation, review, and management of DMFs.

With Celegence’s AI-powered tools, the Publishing &Submission time can be cut in half, and we achieve a 99% first-time acceptance rate of data and documentation by Health Authorities and Notified Bodies.

Drug Master File Submission

Submitting a DMF involves several steps:

  • Preparation: Compile all necessary data and documents.
  • Formatting: Organize the information according to the eCTD format.
  • Submission: Submit the DMF to the regulatory authorities electronically.
  • Maintenance: Update the DMF periodically with any changes or new information.
