Evaluation of the Effect of Dapagliflozin in Combination With Metformin on Body Weight in Subjects With Type 2 Diabetes

August 9, 2013 updated by: AstraZeneca

A 24-week,Multi-centre,Int.,Double-blind,Rand.,Parallel-group,Plac.-Controlled,Phase III Study With a 78-week Ext.Per. to Evaluate the Effect of Dapagliflozin in Combination With Metformin on Body Weight in Subjects With Type2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Metformin Alone

This study is being carried out to see if dapagliflozin in addition to metformin decreases body weight and if so, how it compares with metformin alone.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adjusted Mean Change in Total Body Weight
Time Frame: Baseline to Week 24
To evaluate the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin on total body weight after 24 weeks of oral administration of double-blind treatment.
Baseline to Week 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adjusted Mean Change in Waist Circumference
Time Frame: Baseline to Week 24
To assess the effect of dapagliflozin 10 mg daily in combination with metformin compared to placebo in combination with metformin after 24 weeks of double-blind treatment on waist circumference.
Baseline to Week 24
Adjusted Mean Change in Body Fat Mass
Time Frame: Baseline to Week 24
