  Purpose

This study is being carried out to see if dapagliflozin as an addition to metformin is effective and safe in treating patients with type 2 diabetes when compared to glipizide (sulphonylurea) as an addition to metformin treatment.


Condition Intervention Phase
Type 2 Diabetes
Drug: dapagliflozin
Drug: glipizide
Drug: metformin hydrochloride
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A 52-Week International, Multi-centre, Randomised, Parallel-group, Double-blind, Active-controlled, Phase III Study With a 156-Week Extension Period to Evaluate the Efficacy and Safety of Dapagliflozin in Combination With Metformin Compared With Sulphonylurea in Combination With Metformin in Adult Patients With Type 2 Diabetes Who Have Inadequate Glycaemic Control on Metformin Therapy Alone.

Primary Outcome Measures:
  • Adjusted Mean Change in HbA1c Levels [ Time Frame: Baseline to Week 52 ] [ Designated as safety issue: No ]
    To assess the effect of dapagliflozin plus metformin compared to glipizide plus metformin on the absolute change from baseline in HbA1c level after 52 weeks double-blind treatment in patients with type 2 diabetes who have inadequate glycaemic control on 1500 mg/day or higher doses of metformin therapy alone.


Secondary Outcome Measures:
  • Adjusted Mean Change in Body Weight [ Time Frame: Baseline to Week 52 ] [ Designated as safety issue: No ]
    To assess the effect of dapagliflozin plus metformin compared to glipizide plus metformin on body weight after 52 weeks double-blind treatment.

  • Proportion of Participants With at Least One Episode of Hypoglycemia [ Time Frame: Baseline to Week 52 ] [ Designated as safety issue: Yes ]
    To assess the effect of dapagliflozin plus metformin treatment compared to glipizide plus metformin on the occurrence of hypoglycemic events. Least Squares Mean represents the percent of participants adjusted for HbA1c baseline value.

  • Proportion of Participants With Body Weight Reduction of at Least 5% [ Time Frame: Baseline to Week 52 ] [ Designated as safety issue: No ]
    To evaluate the effect of dapagliflozin plus metformin compared to glipizide plus metformin on body weight assessed by a reduction after 52 weeks of at least 5% compared to baseline. Least Squares Mean represents the percent of participants adjusted for baseline value.
