E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- Demonstrate the superiority of combination of vildagliptin 50mg bid and metformin over metformin monotherapy in treatment-naive patients with T2DM by testing the hypothesis that the risk of initial treatment failure (defined as HbA1c ≥ 7.0%) is lower with the combination of vildagliptin and metformin compared to that with metformin monotherapy
- Demonstrate the long-term efficacy of combination of Vildagliptin 50mg bid and metformin over metformin monotherapy in treatment-naive patients with T2DM by testing the hypothesis that the rate of loss in glycemic control over time (estimated annualized slope of HbA1c over time using a random coefficient model) is lower with the combination vildagliptin plus metformin compared to that with metformin monotherapy |
|
E.2.2 | Secondary objectives of the trial |
Evaluate the effect of initiation of combination regimen with Vildagliptin plus metformin compared with metformin monotherapy in treatment naive patients within up to 5 years of treatment, with regards to:
- Progression of HbA1c from 26 weeks after the start of Period 2 to the end of Period 2 assessed by rate of losss in glycemic control over time
- Progression of FPG assessed by rate of loss in glycemic control over time assessed by estimated annualized slope of FPG over time for periods defined
- Change in HbA1C as defined
- Safety and tolerability
In a subgroup of patients, to evaluate the effect of initiation of combination regimen compared with metformin monotherapy, with regards to:
- beta cell function assessed by insulin secretion rate (ISR)/glucose area under the curve during a standard meal-test at timepoints indicated
- insulin resistance assessed by oral glucose insulin sensitivity (OGIS) during a standard meal-test at timepoints indicated
