Effects of Vildagliptin/Metformin Combination on Markers of Atherosclerosis, Thrombosis, and Inflammation in Diabetics With Coronary Artery Disease

Overview[ - collapse ][ - ]

Purpose The purpose of this study is to demonstrate that combined vildagliptin-metformin therapy is associated with clinically significant reductions in biological markers of inflammation, pro-thrombogenicity, and atherosclerosis as compared to metformin mono-therapy in a population of diabetic patients with coronary artery disease who undergo cardiac rehabilitation. The pre-specified established biological markers of inflammation, pro-thrombogenicity, and atherosclerosis will include: interleukin-6 (IL-6 - primary biological marker), hs-CRP, platelet reactivity testing, MMP-9, Interleukin 1 beta (IL-1 beta) and adiponectin levels.

Brief Summary
The purpose of this study is to demonstrate that combined vildagliptin-metformin therapy is
associated with clinically significant reductions in biological markers of inflammation,
pro-thrombogenicity, and atherosclerosis as compared to metformin mono-therapy in a
population of diabetic patients with coronary artery disease who undergo cardiac
rehabilitation.

The pre-specified established biological markers of inflammation, pro-thrombogenicity, and
atherosclerosis will include: interleukin-6 (IL-6 - primary biological marker), hs-CRP,
platelet reactivity testing, MMP-9, Interleukin 1 beta (IL-1 beta) and adiponectin levels.
Detailed Description
The study is designed as a single-center, randomized, non-blinded, clinical trial to provide
evidence on the effects of vildagliptin on key biomarkers of atherothrombosis and
inflammation. We plan to prospectively enroll 60 patients with proven coronary artery
disease and randomize them in a 2:1 ratio to either vildagliptin-metformin therapy (n=40) or
metformin therapy (n=20).
