Hi @quinnsapp, costs for participants of a clinical trial will vary depending on the study. For example, medical appointments, medicine if required, is usually covered by the facility conducting the study, but travel to the hospital for appointments may not be covered. Sometimes, participants are offered an honorarium to take part in a study.
