FAQ

Common questions

What is a clinical trial?
A clinical trial is a research study in people that tests a medical, surgical or behavioral intervention, such as an investigational drug or device. Observational studies are also listed: they collect information without assigning a treatment. Read how clinical trials work.
Is there compensation for joining a Healthy Volunteers clinical trial?
Compensation for time and travel may be available, but it varies by study and some studies offer none. The amount and schedule are reviewed by an ethics board and described in the consent form. See compensation in clinical trials.
How do I check if I'm eligible?
Each study lists age, sex and other inclusion and exclusion criteria on its ClinicalTrials.gov record. Only the study team can confirm eligibility, usually through a screening call or visit. Talk with your own doctor before joining any study.
