Signaling Mechanisms and Vascular Function in Patients With Diabetes Mellitus
Completed · Phase 2/Phase 3 · Has a placebo group
Conditions studied: Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus
In brief
The purpose of the study is to learn how blood vessel function is altered by diabetes. We are studying an investigational drug, Ebselen, to see if it can improve the ability of blood vessels to relax (widen).
