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

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Biomarker sub-study-
Patients can voluntarily participate in a biomarker sub-study. Samples will be collected from them to be submitted to the innovative Medicines Initiative's (IMI) SAFE-T consortium, sponsored by the European union.
IMS's overall goal is to reinvigorate biopharmaceutical reserach in Europe, initiating and supporting collaboration of the pharmaceutical industry and key stakeholder groups, i.e. academia, biopharmaceutical companies, healthcare providers etc.
Blood samples for assessment of exploratory safety biomarkers taken during this study will be sumbitted to and safely stored in a centralised bio-bank together with the patients' anonymised medical and personal history under strict confidentiality.
Blood and urine samples wil be used by SAFE-T to assess a range of different candidate biomarkers usch as porteins, endogenous metabolites, mRNA, microRNA or DNA. DNA may be used to investigate association of specific gene variants with drug induced organ damage. All investigations will exclusively focus on discovery and qualification of safety biomarkers.
Meal test-
A standard meal test will be performed at visits indicated in a subgroup of 380 patients in order to assess the progression of beta-cell function and insulin sensitivity.
Retinal micro-aneurysm count-
A retinal micro-aneurysm count will be performed in a subgroup of patients by a central assessor. Retinal images will be recroded at sites who are adequately equipped. The procedure is described by the central assessor and will be provided to the participating sites. |
