Under what circumstance may the IRB/IEC require that more information be given to subjects beyond standard guidance?

• A. When additional information would meaningfully protect rights, safety, and/or well-being
• B. Only if required by law
• C. In all cases irrespective of risk
• D. Only after trial completion

Answer: (A)

Protecting participants' rights and welfare drives this rule. The IRB/IEC reviews the consent to ensure it truly supports an informed, voluntary decision to participate. It may require more information beyond standard guidance when doing so would meaningfully protect the rights, safety, and well-being of subjects. This happens if the study presents specific risks, uncertainties, or complexities, or if the population may have trouble understanding the information, so that participants can make a sound choice. It isn’t solely about legal requirements, it isn’t applied in every case regardless of risk, and it isn’t something reserved for after the trial ends.
