This study aims to investigate how dapagliflozin can control blood sugar in patients with type 2 diabetes when added to existing treatments (sitagliptin alone or in combination with metformin). The effect of dapagliflozin on weight and blood pressure will also be studied.

Condition Intervention Phase
Type 2 Diabetes
Drug: Dapagliflozin
Drug: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A 24-week, Multicentre, Randomised, Double-Blind, Placebo-Controlled, Parallel-Group, International Phase III Study With 24 Week Extension to Evaluate the Safety and Efficacy of Dapagliflozin 10 mg/Day in Patients With Type 2 Diabetes Who Have Inadequate Glycemic Control on a DPP-4 Inhibitor Sitagliptin+/-Metformin

Primary Outcome Measures:
  • Adjusted Mean Change in HbA1c Levels [ Time Frame: Baseline to Week 24 ]
    To compare the change from baseline in HbA1c after 24 weeks treatment (LOCF) between dapagliflozin and placebo in patients with type 2 diabetes who are inadequately controlled on sitagliptin alone or on sitagliptin plus metformin.

Secondary Outcome Measures:
  • Adjusted Mean Change in Body Weight [ Time Frame: Baseline to Week 24 ]
    To compare the change in total body weight achieved with dapagliflozin versus placebo from baseline to week 24.

  • Adjusted Mean Change in HbA1c in Participants With Baseline HbA1c ≥8% [ Time Frame: Baseline to Week 24 ]
    To compare the change in HbA1c in participants with baseline HbA1c ≥8% achieved with dapagliflozin versus placebo from baseline to week 24.

  • Adjusted Mean Change in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline to Week 24 ]
    To compare the change in FPG achieved with dapagliflozin versus placebo from baseline to week 24.

  • Adjusted Mean Change in Seated Systolic Blood Pressure (SBP) in Participants With Baseline SBP>=130 mmHg [ Time Frame: Baseline to Week 8 ]
    To compare the change in seated systolic blood pressure (SBP) in participants with baseline seated SBP >=130 achieved with dapagliflozin versus placebo from baseline to week 8.

  • Adjusted Mean Change in 2-hour Post Liquid Meal Glucose Rise [ Time Frame: Baseline to Week 24 ]
    To compare the change in 2-hour post liquid meal glucose rise achieved with dapagliflozin versus placebo from baseline to week 24.

  • Proportion of Participants Achieving a Therapeutic Glycemic Response Defined as a Reduction in HbA1c of ≥0.7% Compared to Baseline [ Time Frame: Baseline to Week 24 ]
    To compare the proportion of participants achieving a therapeutic glycaemic response, defined as a reduction in HbA1c of ≥0.7% compared to baseline, with dapagliflozin versus placebo at week 24. Least Squares Mean represents the percent of participants adjusted for HbA1c baseline value.
