National Clinical Trials

The U.S. National Institutes of Health maintains a registry and results database of publicly and privately supported clinical studies of human participants conducted around the world.

Known by many by its web address, this online database allows visitors to learn more about clinical studies, as well as the history, policies and laws surrounding clinical studies.

If you’re new to the website, it can take some time to acquaint yourself with its structure and how to best search for information that may be of assistance to you and your loved one.


Please note that although trials at Washington University School of Medicine are listed in the database, neither the school or university manage the website.
