Who is permitted to vote on trial-related matters within an IRB/IEC?

• A. Only members independent of the investigator and sponsor
• B. Any member
• C. Only scientists
• D. The sponsor

Answer: (A)

Voting on trial-related matters in an IRB/IEC must be done by members who are independent of the investigator and sponsor. This independence guards the rights and welfare of research participants by ensuring that decisions about risk, benefit, and informed consent aren’t influenced by someone with a personal or financial stake in the study. If a member has a potential conflict, they should recuse themselves from discussion and voting. While others like administrative staff or external consultants may attend for information, they generally do not vote. This setup prevents sponsor or investigator influence from swaying the committee’s judgment, keeping the oversight objective and focused on participant protection.
