What is the role of the IRB/IEC in relation to trial participant enrollment?

The key idea is that protecting participants starts with independent ethics review and formal approval before any enrollment occurs. An IRB/IEC evaluates the study protocol, how informed consent will be obtained, and safeguards for participants’ rights and safety. Only after receiving a documented approval or favorable opinion from the IRB/IEC can enrollment begin, because this approval confirms that the risks are acceptable, benefits are reasonable, and participants will be adequately informed and protected. This approval is not something a sponsor or investigator can substitute for with their own judgment. If the study is conducted in more than one country, ethics approval is typically needed in each country, not just in one. Any changes to the protocol or consent documents usually require a new IRB/IEC review and approval before they are implemented or before enrolling new participants. The IRB/IEC also oversees ongoing safety and compliance through continuing review.
