Outcome Measures for this Clinical Trial

Primary Measures

  • To assess the efficacy of dapagliflozin compared to placebo as add-on therapy to glimepiride in improving glycaemic control in subjects with type 2 diabetes, as determined by the change in A1C levels from baseline to Week 24
    • Time Frame: 24 weeks
      Safety Issue?: No

Secondary Measures

  • To show that dapagliflozin plus glimepiride results in greater reductions in body weight or less weight gain after 24 weeks of treatment when compared to placebo plus glimepiride.
    • Time Frame: 24 weeks
      Safety Issue?: Yes
  • To show that dapagliflozin plus glimepiride results in greater reductions in the 2-h post-challenge plasma glucose level as a response to an oral glucose tolerance test (OGTT) from baseline to Week 24.
    • Time Frame: 24 weeks
      Safety Issue?: No
  • To show that dapagliflozin plus glimepiride results in a larger proportion of subjects achieving a therapeutic glycaemic response, defined as A1C < 7% after 24 weeks of treatment, compared to placebo plus glimepiride.
    • Time Frame: 24 weeks
      Safety Issue?: No
