Change Notification & Significant Changes

Overview

Once a medical device is registered in Malaysia, any proposed changes to the device, its manufacturing, labelling, or associated documentation must be assessed to determine whether they require notification to MDA before implementation.

The underlying principle is that changes that could affect the safety, performance, or risk-benefit profile of the device require regulatory review before they are implemented.

Change Categories

Category 1 — Administrative Changes (Notify, No Prior Approval Needed)

Changes that do not affect safety or performance and require simple notification:

• Change of company name (with no change of legal entity)
• Change of company address (same premises, administrative update)
• Minor IFU or label updates (correcting typographical errors, updating contact details)
• Change of distributor or sub-distributor

Category 2 — Minor Technical Changes (Variation — Prior Approval Required)

Changes that are minor but must be approved before implementation:

• Minor labelling changes affecting instructions or claims
• Change of packaging materials (not sterile barrier)
• Change of sterilisation site (same method, validated)
• Addition of a new size or variant with the same design
• Minor software updates (bug fixes not affecting safety functions)

Category 3 — Major Technical Changes (Full Variation — Prior Approval Required)

Changes that significantly affect the device and require full MDA review:

• Changes to design, materials, or components that could affect safety or performance
• Changes to the manufacturing process that could affect device characteristics
• Changes to sterilisation method
• Changes to the sterile barrier system
• New or extended indications for use
• Software updates that change the intended use or safety functions

Category 4 — Changes Requiring New Registration

Some changes are so significant that a new registration application is required rather than a variation:

• Change of manufacturer
• Complete redesign of the device
• Change of intended use to a fundamentally different clinical application
• Change from non-sterile to sterile supply

Performing a Change Assessment

Before any change is implemented, conduct a formal change assessment:

1. Describe the change clearly — what is changing, why, and how
2. Assess impact on safety and performance — does the change affect the technical specifications, risk profile, or clinical performance?
3. Assess impact on existing documentation — which technical file documents, standards, and test reports are affected?
4. Determine category — using the categories above
5. Implement regulatory action — notification, variation application, or new registration
6. Update technical file — maintain the technical file to reflect the current device configuration

Variation Application Process

For Category 2 and 3 variations:

1. Submit variation application via MyMDA portal
2. Include change description and assessment
3. Submit updated technical documentation (affected sections only for minor; comprehensive for major)
4. Pay variation fee
5. Do not implement the change until MDA approval is received

Processing times:

• Minor variation: ~30 working days
• Major variation: ~90 working days

Variation Fees

Variation Type	Fee (MYR)
Administrative change	RM 100
Minor technical change	RM 300
Major technical change	RM 1,000

Implement Before Approval = Non-Compliance

Implementing a Category 2 or 3 change without prior MDA approval is a regulatory non-compliance that can result in enforcement action, device recall, and registration suspension. Always complete the variation process before implementing.
