Clinical Trials

The Harold Schnitzer Diabetes Health Center Research Department is committed to promoting and conducting excellent 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 as a potential volunteer for our research studies, please call 503-494-4704, complete our Online Application Form for more information.

T1D: Dexcom CGM Exercise Study

 continous glucose monitoring

We are studying exercise & the new Dexcom Continuous Glucose Monitoring (CGM) system.

The purpose of this study is to test a new Dexcom CGM and to determine if weekly insulin dose changes by the study investigator will improve managing blood sugar in people living with type one diabetes and exercising.You will use a mobile app to track your physical activity and meal data while at home. Meal tracking will include before &after meal images. You also will be given short &long acting insulin pens. You will be compensated up to $500 for participating.

T1D: Closed-loop Study

Enso Circle

You may be able to participate in an artificial pancreas study involving the use of an investigational, stable form of glucagon. The automated system involves the use of a Dexcom G6 glucose sensor, the Omnipod insulin pump and a computer program that determines rates of insulin and glucagon to deliver. Participants will be compensated up to $600 for participating.

You may be eligible if you:

  • Have type 1 diabetes
  • Between the ages of 21 to 50
  • Currently use an insulin pump
  • Ability to exercise for up to 45 minutes

What is involved?

  • 2.5-hour screening visit
