Which of the following roles has direct access to subject medical records under ICH E6 requirements?

Under ICH E6 requirements, regulatory authority representatives have a critical role in ensuring the safety and efficacy of clinical trials. They possess the authority to access various documents associated with the conduct of the study, which includes reviewing subject medical records when necessary. This access is vital for regulatory oversight, as it allows these representatives to verify that the trial is being conducted in accordance with regulatory standards and that the rights and welfare of the subjects are adequately protected.

The role of regulatory authority representatives is specifically supported by the principles outlined in ICH E6, which emphasizes the importance of transparency and oversight in clinical trials. This access is typically governed by strict confidentiality and ethical considerations, ensuring that subjects' privacy is maintained while providing necessary information for regulatory purposes.

In contrast, other roles listed, such as insurance representatives, trial monitors, and marketing teams, do not generally have direct access to subject medical records under these guidelines. Insurance representatives primarily focus on assessing claims related to the study, trial monitors oversee the compliance and progress of the study but do not require access to individual medical records, and marketing teams handle promotional activities rather than regulatory oversight, which means they do not need such access.
