Clinical Trials

The Harold Schnitzer Diabetes Health Center is committed to promoting 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 Diabetes Research Application Form for more information.

Current Studies:

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 and after meal images. You also will be given short and long acting insulin pens. You will be compensated up to $700 for participating.

You may be eligible if you:

  • Have type 1 diabetes
  • Are between the ages of 18 to 50
  • Are using multiple daily insulin injections
  • Physically able to perform exercise for 30 minutes of exercise
What is involved?
  • Six visits to OHSU, each visit is 2.5 hours or less
  • Study last for 28 days
  • Wear a Dexcom CGM and smartwatch
  • You will exercise at home for 4 days and use a mobile app to track your activity and meals, including taking before and after images of your meals

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
  • 1 hour training visit
  • Exercise for 76 hours, which will be broken down into time within clinic and at home
  • Use of the Omnipod and Dexcom G6
