Appraising Harm in Phase I Trials: Healthy Volunteers' Accounts of Adverse Events.

While risk of harm is an important focus for whether clinical research on humans can and should proceed, there is uncertainty about what constitutes harm to a trial participant. In Phase I trials on healthy volunteers, the purpose of the research is to document and measure safety concerns associated with investigational drugs, and participants are financially compensated for their enrollment in these studies. In this article, we investigate how characterizations of harm are narrated by healthy volunteers in the context of the adverse events (AEs) they experience during clinical trials.
