Participating in a Clinical Study

Clinical studies all have a study protocol that describes who is eligible to be a participant. Participants are selected based on whether their age, type and stage of disease, previous treatment history and other medical conditions fit with the requirements for the study. Consulting your doctor can help you determine if the study is right for you.
