Data Safety Monitoring Board (DSMB) Oversight and Reporting SOP

Purpose

The purpose of this SOP is to outline the establishment, responsibilities, and operational procedures for the Data Safety Monitoring Board (DSMB) in clinical trials conducted in New Zealand. It ensures compliance with Medsafe, HDEC, and international GCP requirements, protecting trial participants through independent oversight of safety and efficacy data.

Scope

This SOP applies to all clinical trials in New Zealand requiring independent DSMB oversight due to high-risk interventions, large sample sizes, or regulatory/ethics committee requirements. It covers DSMB charters, meeting schedules, safety data review, interim reporting, and archiving of DSMB documentation.

Responsibilities

• Sponsor: Establishes DSMB, provides charter, and ensures access to safety data.
• Principal Investigator (PI): Provides timely safety reports to DSMB and complies with recommendations.
• DSMB Members: Independently review safety/efficacy data, make recommendations regarding trial continuation, modification, or termination.
• Regulatory Affairs (RA): Submits DSMB reports to HDEC and Medsafe when required.
• Quality Assurance (QA): Audits DSMB operations and documentation.

Accountability

The sponsor’s Head of Clinical Operations is accountable for ensuring DSMB oversight processes are in place. DSMB Chair is accountable for impartial recommendations regarding trial safety and continuation.

2. Provide interim analyses to DSMB for blinded/unblinded review.

3. DSMB Meetings

2. Document minutes and recommendations in DSMB Meeting Log (Annexure-2).

4. Recommendations and Communication

1. DSMB issues recommendations to sponsor regarding trial continuation, modification, or termination.
2. Sponsor communicates DSMB recommendations to PI, CRO, HDEC, and Medsafe.

5. Archiving

1. Maintain DSMB records in TMF and ISF.
2. Archive all reports for a minimum of 10 years post-trial completion.
