Clinical research studies aim to evaluate investigational drugs for conditions, like behavioral changes resulting from a traumatic brain injury (TBI).
Clinical research helps doctors and scientists determine if an investigational drug or therapy is safe and/or effective for use in humans to potentially treat a condition, disease, or disorder. Clinical studies often require a large number of volunteers to participate in a single study. Sometimes thousands are needed to obtain reliable information. Right now, there are over 300,000 clinical studies in progress all over the world.
