MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of 24 month Vildagliptin treatment to reduce the progression to type 2 diabetes in islet autoantibody negative women with recent insulin treated GDM. |
|
E.2.2 | Secondary objectives of the trial |
To determine the mechanism of action of Vildagliptin treatment by testing the hypothesis that Vildagliptin 100 mg qd improves beta cell function and insulin sensitivity. To determine the durability of clinical benefit of 24 month Vildagliptin 100 mg qd treatment.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary end point will be diabetes diagnosed on the basis of a six-monthly oral glucose tolerance test according to the 1997 criteria of the American Diabetes Association: a value of plasma glucose above 140 mg/dl in the fasting state or 200 mg/dl two hours after a 75 g oral glucose load. Diagnosis will require confirmation by a second test within 6 weeks. If the diagnosis is not confirmed by the second test, the subject will continue treatment to the original random assignment. |
