Other info to think about when joining a study

If you are interested in joining a clinical trial, the study team will ask you some questions and possibly do some medical tests to make sure you meet the eligibility criteria. This is for your safety and for scientific reasons so participants all meet specific criteria.

If you do not meet the eligibility criteria for one study, you can ask the study team if there are other studies that you could be a good fit for.
