Completed Clinical Trials

Our commitment to research excellence and personalized patient care is demonstrated by the more than 500 clinical trials we've completed in Portland, Oregon since 1998.

Our success is in part a direct reflection of our volunteers, who are our partners in new treatment discovery.
