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. |

Current Primary Outcome Measures | Reduction in serum levels of Interleukin 6 (IL-6) [Time Frame: 3 months] [Designated as safety issue: No] |
Current Secondary Outcome Measures | Improvement in other markers of athero-thrombosis and inflammation: [Time Frame: 3 months] [Designated as safety issue: No]I. Improvement in other markers of athero-thrombosis and inflammation: High sensitivity C-reactive protein (hs-CRP), Platelet reactivity Adiponectin levels IL-1 beta Matrix metallo-peptidase 9 (MMP-9) Additional exploratory markers including: IL-1 alpha ,, IL-17, TNF-alpha, MCP-1 |

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.

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). |
