Which responsibility falls under the sponsor's domain according to ICH E6?

The responsibility that falls under the sponsor's domain, as outlined in ICH E6, is the obligation to offer compensation to subjects. Sponsors are tasked with ensuring that participants are adequately informed about the study and that their health and welfare are prioritized throughout the trial. Part of this obligation involves providing compensation for any potential risks that participants take on during the research process. This may include financial compensation for time lost, expenses incurred, or any medical care related to the trial that may not be covered by their health insurance.

This aspect of the sponsor's responsibility emphasizes the need to maintain ethical standards and protect the rights of study participants, highlighting the importance of a fair compensation framework. By ensuring that subjects are compensated, the sponsor demonstrates a commitment to safeguarding their well-being and recognizing the value of their participation in the study.

Other activities, such as conducting patient interviews or overseeing medical care, are primarily the responsibilities of the investigators or medical personnel rather than the sponsor. Similarly, while providing training for investigators may seem closely related to the sponsor's responsibilities, it is fundamentally about preparing the investigators to conduct the trial according to protocols and regulations, rather than the direct management of patient compensation.
