Informed consent of trial participants
You understand that consent is a process, not a signature. You understand that it must be voluntary, informed, and ongoing. You understand the ethical foundation laid by Principle 2 and its sub-principles. Now we turn to the procedural requirements that translate those principles into daily practice.
Section 2.8 of ICH E6(R3) Annex 1 is extensive, and deliberately so. It specifies what the consent document must contain, how the consent discussion must be conducted, what must be documented, when re-consent is required, and how consent works when participants cannot consent for themselves. These are not bureaucratic requirements imposed on an otherwise straightforward process. They are the operational translation of ethical obligations into verifiable procedures.
I have reviewed hundreds of informed consent forms over my career, and I can tell you that the quality varies enormously. Some forms meet every regulatory requirement while failing entirely to communicate clearly with the reader. Others are models of clear communication but omit required elements. The goal is both: complete regulatory compliance and genuine participant understanding. Section 2.8 provides the framework for achieving that goal.
This lesson assumes you have mastered the principles of informed consent from earlier in this course. We will not revisit why consent matters or what makes it ethical. Instead, we focus on how to implement consent procedures that satisfy both regulatory requirements and ethical obligations.
