Clinical trials are carefully controlled research studies in which people volunteer to test the safety and effectiveness of new drugs, medical products or techniques. Each study gathers scientific evidence to find better ways to prevent, diagnose or treat medical conditions. In the U.S., all drugs undergo rigorous clinical trials before being approved for use by the general public.

Clinical trials are an integral part of medicines and devices getting approved for use. In addition, many people enrolled in clinical trials have been helped as a result of having access to leading-edge care they otherwise would not have had. Quite often the first people to have been helped by a medication or medical device are people who were part of its clinical trial.
Clinical Trials at the Sleep Therapy & Research Center

At the Sleep Therapy & Research Center, we have been one of the only research centers for sleep disorders in San Antonio since 2006. We have conducted numerous clinical trials over the years and helped companies launch drugs and products that have subsequently improved the health and lives of thousands of patients suffering from sleep disorders.

If you are interested in enrolling in a clinical trial, sign up now. One of our staff will contact you to let you know if you meet the qualifications for participating in one of our studies.
