This process is called informed consent and is essential before any volunteer is enrolled in any clinical trial. In addition, a full medical history is obtained and a physical exam and lab testing is done to make sure there is no contraindications for your participation in the clinical trial. All clinical trials require a time commitment and study schedules vary depending on the individual study. Participation in any clinical trial is voluntary. If you feel any pressure to volunteer for a clinical trial, you probably should not enroll.
Volunteers can change their minds and withdraw from the study at any time.
Any information obtained in a clinical trial remains confidential and is not shared unless authorized by the participant.
