In what circumstances can the informed consent process be waived according to ICH E6?

The informed consent process can be waived in situations where the research involves minimal risk to participants and it is impracticable to obtain consent. This aligns with ethical standards that allow for flexibility in consent requirements when the potential benefits of the research outweigh the risks involved. The rationale is that if the risk is minimal, the burden of obtaining consent may hinder the research without significantly enhancing participant safety.

This circumstance allows researchers to proceed with studies that might otherwise be stalled by the requirement for consent, especially in cases where obtaining consent is not feasible due to the nature of the study or the population involved. It’s important that any waiver of consent still maintains respect for the individuals involved, ensuring that their rights and well-being are protected to the greatest extent possible.

The other options do not meet the necessary criteria outlined by ICH E6 for waiving informed consent. For instance, having participants fully aware of the study risks does not justify a waiver, as informed consent needs to be actively obtained regardless of their awareness. Conducting a study online alone does not inherently waive the need for consent, as ethical considerations still apply. Lastly, having a guardian present does not negate the need for informed consent; rather, appropriate consent must be obtained from guardians if a participant is unable to
