Standard Operating Procedure for Conducting Interim Analyses and Utilizing Data Monitoring Committees in Clinical Research

Purpose

This SOP outlines the procedures for conducting interim analyses and utilizing data monitoring committees (DMCs) in clinical trials and clinical studies. The goal is to ensure participant safety, study integrity, and data quality through regular review and oversight.

Scope

This SOP applies to all personnel involved in clinical trials and clinical studies, including principal investigators, study statisticians, clinical research coordinators, and members of data monitoring committees.

Responsibilities

• Principal Investigator (PI): Works with the DMC and study statistician to plan and conduct interim analyses.
• Study Statistician: Conducts interim analyses and presents findings to the DMC.
• Data Monitoring Committee (DMC): Reviews interim analysis data, monitors study progress, and makes recommendations regarding continuation, modification, or termination of the study.
• Clinical Research Coordinators: Facilitate data collection and transfer for interim analyses and assist in implementing DMC recommendations.

Procedure

• Planning and Scheduling:
  • Define the schedule for interim analyses and DMC meetings in the study protocol.
  • Establish the criteria for conducting interim analyses, including data points and analysis endpoints.
• Conducting Interim Analyses:
  • Collect and clean the data to be analyzed according to the study schedule.
  • Perform interim analyses as defined in the study protocol, ensuring statistical rigor and data quality.
  • Prepare reports and presentations of interim analysis findings for the DMC and study team.
• Data Monitoring Committee (DMC) Oversight:
  • Establish a DMC with appropriate expertise and independence to review interim analysis data and monitor study progress.
  • Provide DMC members with interim analysis reports and other relevant study information.
  • Allow DMC to make recommendations regarding the continuation, modification, or termination of the study based on interim analysis data and other factors.
• Implementing DMC Recommendations:
  • Work with the study team to implement DMC recommendations promptly.
  • Document DMC recommendations and actions taken in response to them.
  • Communicate changes resulting from DMC recommendations to relevant stakeholders, including participants, regulatory bodies, and sponsors.
