DMF Submission in Malaysia: Complete Guide for Pharmaceutical Regulatory Submission

3 min read

DMF Submission in Malaysia is a critical Regulatory requirement for pharmaceutical companies planning to register products containing Active Pharmaceutical Ingredients (APIs) in the Malaysian market. As part of the broader pharmaceutical Regulatory submission framework, the Drug Master File (DMF) is evaluated by the National Pharmaceutical Regulatory Agency (NPRA) to ensure API quality, safety, and compliance with national and international Regulatory standards.

1. DMF Submission in Malaysia: Purpose and Scope

The DMF is a confidential technical dossier containing thorough information about the manufacture, quality control, and stability testing/information of APIs.
It is typically required for products using APIs manufactured by external parties, or where the registration holder is not the API producer.
The Malaysian drug master file requirements aligns with international best practices through the use of the ASEAN Common Technical Dossier (ACTD) or Common Technical Document (CTD) structure.
The DMF enables confidential sharing of sensitive manufacturing and quality details with regulators, protecting proprietary knowledge for API manufacturers.

2. Submission Prerequisites for DMF Submission in Malaysia

For a successful DMF Submission in Malaysia, NPRA outlines specific prerequisites that must be met before filing.

Submission Party: The API manufacturer (or their designated agent) is responsible for preparing and authorizing submissions of the DMF.
Authorization: NPRA requires a formal letter of authorization from the API manufacturer, explicitly permitting the regulator to access and assess confidential content.
Confidentiality: The DMF remains proprietary to the API manufacturer, safeguarding trade secrets while ensuring Regulatory access for product evaluation.

3. Key Components of the DMF

A complete DMF Submission in Malaysia must comprehensively address the following components:

Full identification and background of the API manufacturer.
Complete description of the manufacturing process, including controls over intermediates, starting materials, reagents, and solvents.
Detailed analytical and quality control procedures, including method validation.
Specifications with Certificates of Analysis for the API.
Stability data demonstrating the API’s shelf life and storage requirements.
Information on packaging and the container/closure system.
Documentation demonstrating current Good Manufacturing Practice (GMP) compliance.
These elements form the foundation of the Malaysia DMF registration process under NPRA review.

4. DMF Submission in Malaysia via API Dossier Submission NPRA QUEST 3+

Online Portal: DMF submissions must be made electronically via NPRA’s QUEST 3+ system, and it has to be submitted simultaneously with the finished product registration
Document Format: The dossier should follow the ACTD/CTD structure, with all sections clearly labeled and organized.
Supporting Letters: Each submission requires a formal cover letter (using NPRA’s specified template) and, if relevant, a declaration letter should the API already be registered or approved in Malaysia.
Access Authorization: The API manufacturer must specifically grant NPRA rights to access and use the DMF for Regulatory review purposes.

5. Review and Post-Submission Steps

Assessment: After submission, NPRA reviews and assesses the DMF as a central part of the product registration process. The agency may request clarifications or additional information if needed.
Updates and Amendments: Any post-approval changes to the API (manufacturing process, raw materials, specifications, etc.) must be promptly updated in the DMF and submitted to NPRA.
Ongoing Compliance: Continued monitoring and adherence to GMP, as well as timely provision of new or updated stability and safety data, are required for ongoing approval.

Summary

Section	Summary
Purpose & Scope	DMF is a confidential dossier detailing API manufacturing, quality, and stability. Required when APIs are imported or manufactured by third parties. Uses ACTD/CTD format. Protects proprietary API manufacturer data while enabling NPRA review.
Submission Prerequisites	Submitted by API manufacturer or authorized agent. NPRA requires a written authorization letter granting access to the DMF. DMF remains confidential to protect trade secrets.
Key Components of DMF	Manufacturer information. Detailed manufacturing process & controls. Analytical methods & validations. API specifications + CoA. Stability data (shelf life, storage). Packaging/container details. GMP documentation.
Submission Process	Submitted online through NPRA’s QUEST 3+ portal. Must follow ACTD/CTD format with clear labeling. Include NPRA-template-based cover letter and declaration letter (if API is already approved). API manufacturer must authorize NPRA access.
Review & Post-submission	NPRA evaluates the DMF as part of the product registration review. Additional information may be requested. Any changes (process, materials, specs) require DMF updates. Continuous GMP compliance and stability updates are mandatory.
