Five Questions to Ask Before Joining Any Clinical Trial

1. What is the purpose of the study? You should always understand what the investigational treatment is and what question the research is trying to answer.

2. What are the possible risks and benefits? Every consent form lists known side effects. Ask the physician to walk you through them in plain language.

3. What will I be asked to do? Understand the visit schedule, procedures, and time commitment before you sign anything.

4. Can I leave the study? Yes — always, at any time, for any reason. If a site tells you otherwise, walk away.

5. Who pays for what? Study-related care is provided at no cost, and most studies compensate you for time and travel. Get the specifics in writing.
