Clinical ResearchInformation for our Volunteers

Volunteer participation in clinical studies remains essential to the successful development of new and better medications. All studies are overseen by an experienced research physician who monitors you throughout your participation in the trial and every trial in the US requires approval and monitoring by an Institutional Review Board. If you are eligible for a trial you will receive study exams and study intervention at no charge to you. You are not required to have health insurance to participate. You may be compensated for your time and travel. Our patients come first, our research staff and physicians are here for you if you have any questions or concerns.
