RESEARCH
Clinical Trials in Canada
In the past couple of decades, PH medical research has evolved immensely throughout the world. Medical professionals are delving deeper into the science and uncovering new information every day. And while this has taken place internationally, we are incredibly fortunate to have leading research and clinical trials taking place right here in Canada.
How can I participate in PH research?
Patient participation in research is essential to making scientific advancements in the diagnosis and treatment of PH. Numerous early-stage and clinical-stage research studies are currently taking place in research centres throughout Canada. Check out the list below for more information on studies that are currently recruiting participants. For additional information, speak to your PH medical team or visit ClinicalTrials.gov.
Disclaimer: This information is updated every 4-6 months. The latest update was in October 2023. PHA Canada is not responsible for errors or omissions.
Thanks to advancements in research, many PH treatments are available in Canada. However, they aren’t always available through public funding in every province and territory. This means people in some parts of the country don’t have equal access to the vital treatments they need. Visit our advocacy section to learn more and join us in representing a united PH community.
