Must an AE be related to study drug?

• A. Yes.
• B. No.
• C. Only if SAE.
• D. Only if it is expected.

Answer: (B)

An adverse event does not have to be related to the study drug. In clinical trials, investigators collect all untoward medical occurrences that happen to participants and then assess causality to decide if the event is likely related to the drug. Many AEs occur coincidentally or due to other factors such as underlying conditions, other medications, or lifestyle, so they are not considered drug-related. Therefore, the correct answer is that an AE need not be related to the study drug. Notes: seriousness (SAE) and whether an event is expected influence reporting and evaluation, but they do not by themselves determine relatedness.
