The goal of a clinical trial is to find safe and effective treatments to help treat medical conditions and improve patient health. Here at Tristar Clinical Investigations, we are trying to prove there is a chance that a new medical treatment is more effective than a current treatment.

    Volunteers who participate in a clinical trial will receive medical care at no cost. Volunteers will also be reimbursed for their time and travel.
