Find a clinical trial at The Ottawa Hospital

Clinical trials are used to determine the safety and effectiveness of treatments, devices and procedures. Participating in a clinical trial may or may not benefit you personally, but it will contribute to new knowledge that will help others.

How to use the tool:

  • Search for studies by disease or condition.
  • Bring what you find to your next appointment with your care team and ask them if you are eligible for the study.
  • If your care team think you may be eligible, you can ask them to refer you to the study team.

Please note:

  • We cannot guarantee a response from the person listed in the ‘Contact’ column. For best results, bring the information you find to your next appointment with your care team.
  • Information in this table comes from ClinicalTrials.gov, a resource provided by the U.S. National Library of Medicine, and is only available in English.
