Study Details

Study Description

Brief Summary

This study is carried out to assess whether dapagliflozin improves glycemic control, decreases fasting plasma glucose levels, body weight and blood pressure when added to patient's existing medications and how it compares with their usual treatment without added dapagliflozin. Safety data will be collected and analysed to confirm that treatment with dapagliflozin is safe and well tolerated in patients who have diabetes and cardiovascular disease

Outcome Measures

Primary Outcome Measures

  1. Adjusted Mean Change in HbA1c Levels [Baseline to Week 24]

    To compare the glycemic efficacy of dapagliflozin 10 mg versus placebo when added to usual care in type 2 diabetes patients with cardiovascular disease, measured as the mean change in HbA1c from baseline to week 24.

  2. Proportion of Responders Meeting All Criteria of a 3-item Endpoint of Clinical Benefit [Baseline to Week 24]

    To compare the clinical benefit of dapagliflozin 10 mg versus placebo when added to usual care in type 2 diabetes patients with cardiovascular disease at week 24, measured as the proportion of responders for a 3-item endpoint of clinical benefit, defined as an absolute drop of 0.5% or more from baseline HbA1c, and a relative drop of 3% or more from baseline for total body weight, and an absolute drop of 3 mmHg or more from baseline in seated systolic blood pressure.

Secondary Outcome Measures

  1. Adjusted Mean Percent Change in Body Weight [Baseline to Week 24]

    To compare the mean percent change in body weight from baseline to week 24 between dapagliflozin 10 mg versus placebo.

  2. Proportion of Participants With a Reduction From Baseline of 5% or More in Body Weight in Participants With Baseline BMI ≥27 kg/m² [Baseline to Week 24]

    To compare the proportion of participants with BMI baseline ≥27 kg/m2 with a reduction from baseline of 5% or more in body weight with dapagliflozin 10 mg versus placebo from baseline to week 24. Least Squares Mean represents the percent of participants adjusted for baseline body weight and age stratum.

  3. Adjusted Mean Change in Systolic Blood Pressure at Week 8 (LOCF) [Baseline to Week 8]

    To compare the mean change in seated systolic blood pressure from baseline to week 8 between dapagliflozin 10 mg versus placebo.

  4. Adjusted Mean Change in Seated Systolic Blood Pressure at Week 24 (LOCF) [Baseline to Week 24]

    To compare the mean change in seated systolic blood pressure from baseline to week 24 between dapagliflozin 10 mg versus placebo.

  5. Adjusted Mean Change in Seated Systolic Blood Pressure (SBP) at Week 8 (LOCF) in Participants With Baseline SBP>=130 mmHg [Baseline to Week 8]

    To compare the mean change in seated systolic blood pressure (SBP) in participants with baseline seated SBP ≥130 mmHg achieved with dapagliflozin versus placebo from baseline to week 8.

Participant Flow

Recruitment Details First participant enrolled 15 Mar 2010, last part. last visit for 24-week period: 30 May 2011. 1489 part. enrolled, 964 randomized in USA, Canada, Australia, Chile, Argentina and 5 European countries (value presented in 'Enrolment' field). One add. part. treated but not randomized. Part. with T2DM and CVD who showed inadequate glycemic control.
Pre-assignment Detail During a placebo lead-in period, participants were counselled on dietary and life-style modifications. Anti-diabetic therapy should be kept constant 4 weeks prior to enrolment. Participants eligible for the study were stratified according to age (<65 years or ≥65 years), insulin use and time from most recent qualifying CV event (>1 or ≤1 year).
