Efficacy and Safety of Dapagliflozin in Combination With Glimepiride (a Sulphonylurea) in Type 2 Diabetes Patients - Full Text View

Purpose

This study is being carried out to see if dapagliflozin in addition to glimepiride (sulphonylurea) is effective and safe in treating patients with type 2 diabetes when compared to glimepiride alone.

Primary Outcome 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 ] [ Designated as safety issue: No ]

Secondary Outcome 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 ] [ Designated as safety issue: No ]
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 ] [ Designated as 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 ] [ Designated as safety issue: No ]
