MeasureTime frame
Main Objective: The primary objective of this study is to assess a superior efficacy and durability of the DPP-IV inhibitor Vildagliptin as an add-on treatment to Metforminin in comparison to Glibenclamide in terms of achievement and maintenance of a good glycemic control (HbA1c < 7%) in type 2 diabetic patients in failure with Metformin as monotherapy over a period of 36 months;Secondary Objective: -Primary objective measured at the end of follow-up(including Extension Phase),measured as % of patient developing primary or secondary failure with the association of Metformin plus one of the two experimental treatments(Glibenclamide or Vildagliptin-Absolute change of HbA1c on the short-term(month 4,V2)and long-term(month 36,V12)compared to randomization(V0)-Percent of patients achieving HbA1c goal(<7%)on the short-term(month 4,V2)-Percent of patients developing secondary failure(defined as HbA1c &amp;#8805;7% from V4 to the end of the experimental period)among the ones who achieve HbA1c < 7% within 8 months(V3-Time on months from the first treatment dose to the occurrence of treatment failure based on the definition used for primary end-point determination-Absolute and percent change in body weight at 36 months(V12)compared to randomization(V0)-Long-term safety and tolerability as total number and type of adverse events-Long-term change in insulin secretion;Primary end point(s): Percent of patient developing primary or secondary failure with the association of Metformin plus one of the two experimental treatments (Glibenclimide or Vildagliptin). Primary failure is defined as HbA1c &amp;#8805; 8% at V2 (four months of follow-up) or HbA1c &amp;#8805; 7% at V3 (eight months of follow-up). Secondary failure is defined as HbA1c &amp;#8805; 7% after V3 (from V4 to V12 included).
