E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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. |
|
E.2.2 | Secondary objectives of the trial |
Key secondary objectives − 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. − 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. − To show that dapagliflozin plus glimepiride results in a larger proportion of subjects achieving an A1C < 7% after 24 weeks of treatment compared to placebo plus glimepiride. − To show that dapagliflozin plus glimepiride results in greater reductions in body weight or less weight gain in subjects with baseline BMI ≥ 27 kg/m2 after 24 weeks of treatment when compared to placebo plus glimepiride. − To show that dapagliflozin plus glimepiride leads to greater reductions in FPG after 24 weeks of treatment compared to placebo plus glimepiride.
