What is a clinical trial?
A clinical trial is how a new treatment gets tested in people before doctors can use it for everyone. Every medicine you have ever taken went through one.
Volunteers often get early access to new treatments, usually with study care and tests at no cost, and they help future patients. You can leave a trial at any time.
