Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE)
In this study, we will compare the effectiveness of four different medications that are used to treat type 2 diabetes. We want to learn:
a. How well different medication combinations control blood sugar levels in people with type 2 diabetes.
b. More about the benefits or side effects of each medication combination.
c. What is the best treatment for type 2 diabetes.

Healthy Volunteers Needed
Duration of Participation
This study is being done in two phases, Phase 1 is screening/run-in and Phase 2 is the GRADE clinical trial. The screening and run-in period (Phase 1) will take about 6-12 weeks to complete. During screening and run-in, you will have 2 or 3 study visits to OHSU. Your participation in the GRADE clinical study (Phase 2) will be for 4 years up to 7 years depending on when you enroll. The study is planned to end in 2020. Phase 2 visits will be every 3 months. Most of these visits will take about an hour. Once each year you’ll have a longer visit (5 hours) that will require that you fast (nothing to eat for at least 8 hours before the visit).
