What aspect is not specifically addressed by FDA regulations according to ICH E6?

Non-therapeutic trials, which refer to clinical studies where the primary purpose is not to provide direct benefit to the participants but rather to gather data or answer scientific questions, are indeed covered under ICH E6 guidelines in terms of ethical considerations. However, the FDA regulations do not specifically address these trials in the same way as ICH E6 does.

While ICH E6 emphasizes the importance of ethical standards in conducting all types of clinical trials, including those that are non-therapeutic in nature, the FDA regulations are primarily focused on ensuring the safety and efficacy of investigational drugs and devices. Therefore, while broader ethical considerations might be impacted by the regulations, the specifics of non-therapeutic trials are not directly outlined in the FDA regulations.

In contrast, payment to subjects, responsibilities of the investigator, and informed consent documentation are integral components of both ICH E6 guidelines and FDA regulations, as they are fundamental to the protection of human subjects and the integrity of clinical trials.
