Clinical Trials

The Harold Schnitzer Diabetes Health Center Research Department is committed to promoting and conducting cutting-edge clinical research. Our goal is to enhance the quality of life of those living with or affected by diabetes.

Our efforts to find a cure for diabetes, and to improve life for people with this condition, are made possible by volunteers who participate in research studies. When you volunteer, you help us answer important questions about diabetes.

If you would like to be considered to participate in any of our research studies below, please call 503 494-4704, complete our Online Application Form, or email DMResearchCenter@ohsu.edu for more information.

If you join GRADE, you will:

  • Come to Oregon Health & Science University for four diabetes medical visits each year for up to 7  years
  • Take metformin plus one of 4 other diabetes medications chosen by chance
  • Receive diabetes treatment, FDA approved medicines and supplies at no cost to you
  • Receive physical exams and lab tests at no cost to you
