Who can participate in a clinical trial?
Almost anyone can be eligible for a clinical trial — the right study just has to match your situation. Every trial has its own inclusion and exclusion criteria, written by the study sponsor and approved by an Institutional Review Board (IRB). Criteria typically cover your age, diagnosis, how long you've had the condition, prior treatments, other health conditions, current medications, and sometimes lab values like A1c or blood pressure. Some trials specifically recruit healthy volunteers; others focus on people who have not responded to standard therapy. When you submit your ZIP code and condition on QualifiedStudies, our matching engine narrows the nationwide registry down to research sites whose open protocols fit your profile. A research coordinator then calls you within 48 hours, walks through a brief pre-screen, and explains the next steps if you appear eligible. There's no cost, no insurance requirement, and no obligation to enroll — you can stop the process at any point.
