What researchers measure

Primary outcomes

  1. To evaluate the efficacy of vildagliptin as add-on therapy to metformin in patients with T2DM by assessing changes in HbA1c with vildagliptin added to metformin to that of placebo added to metformin after 24 weeks of treatment

    Time frame: 24 weeks

Secondary outcomes

  1. To evaluate the efficacy of vildagliptin as add-on therapy to metformin in patients with T2DM by assessing changes in HbA1c with vildagliptin added to metformin to that of sitagliptin added to metformin after 24 weeks of treatment.

    Time frame: 24 weeks

  2. To evaluate the efficacy of vildagliptin as add-on therapy to metformin in patients with T2DM by assessing changes in fasting plasma glucose with vildagliptin added to metformin to that of placebo added to metformin after 24 weeks of treatment.

    Time frame: 24 weeks

  3. To evaluate the efficacy of vildagliptin as add-on therapy to metformin in patients with T2DM by assessing changes in fasting plasma glucose with vildagliptin added to metformin to that of sitagliptin added to metformin.

    Time frame: 24 weeks

  4. To evaluate the safety and tolerability of vildagliptin compared to placebo and sitagliptin over 24 weeks of treatment as add-on therapy to metformin in patients with T2DM.

    Time frame: 24 weeks

  5. To evaluate the long-term safety and tolerability of vildagliptin compared to sitagliptin over the entire study duration as add-on therapy to metformin in patients with T2DM.

    Time frame: 76 weeks

  6. To evaluate the body weight change from baseline with vildagliptin compared to placebo and sitagliptin after 24 weeks of treatment as add-on therapy to metformin in patients with T2DM.

    Time frame: 24 weeks

  7. To evaluate the long-term efficacy of vildagliptin compared to sitagliptin over the entire study duration as add-on therapy to metformin in patients with T2DM.

    Time frame: 76 weeks
