Clinical Trials

Today’s research is tomorrow’s treatment! This is particularly true here at the University of Ottawa Heart Institute, where research spans from the laboratory to the patient’s bedside and back.

At any given time, the Heart Institute may have up to 200 active clinical trials, in various stages of the lifecycle of a study. Some projects are conducted only here at the Institute, while others are large national or international projects; some are led by us and others we participate in as a site. Thousands of patients and, in some cases, healthy volunteers, participate in our studies annually. Currently, we have 50 Scientists and Clinician Investigators leading research trials on site.
