Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The main objective is to assess the effect of additional Vildagliptin on beta cell function and cardiovascular risk compared to therapy with Metformin and Glimepiride in T2DM patients previously on Metformin monotherapy by means of postprandial intact proinsulin levels.;Secondary Objective: 1. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on beta cell function 2. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on blood glucose control and hypoglycemic events 3. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on body weight 4. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on blood pressure 5. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on endothelial function and cardiovascular risk markers 6. To assess the effect of Metformin and Vildagliptin compared to Metformin and Glimepiride (1-4 mg) on inflammation markers 7. To evaluate the collected safety parameters ;Primary end point(s): Postprandial increase in intact proinsulin levels in patient treated with Vildagliptin and Metformin compared to intact proinsulin levels in patients treated with Glimepiride and Metformin (Area under the curve 0-300 min).;Timepoint(s) of evaluation of this end point: End of study (after approx. 12 month) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Fasting intact proinsulin levels 2. Max postprandial intact proinsulin levels 3. Blood glucose control (HbA1c, fasting blood Glucose, number of hypoglycemic events) 4. Analysis of the following markers for endothelial function and cardiovascular risk: • retinal endothelial response to flicker light stimulation • retinal arterial wall to lumen ratio (WLR) • mean 24h systolic and diastolic blood pressure • mean daily 12 hour systolic and diastolic blood pressure • mean nocturnal 12 hour systolic and diastolic blood pressure • erythrocyte deformability • blood lipids • Adiponectin • BNP • PAI-1 • ADMA • cGMP 5. Analysis of markers for subclinical inflammations: • E-selectin • hs-CRP 6. Change in body weight ;Timepoint(s) of evaluation of this end point: End of study (after approx. 12 month) | — |
