@starman, the eligibility for clinical trials varies from trial to trial. Many trials at Mayo Clinic are open to international patients. Others are multi-center trials that may include institutions in other countries as well as at Mayo Clinic, such as in Canada, Mexico, Europe, etc.

If you would like to speak to a clinical trial coordinator to learn more, you can find contact information and more here: https://www.mayo.edu/research/clinical-trials

Were you interested in a specific clinical trial?
