Dapagliflozin Added to Usual Care in Individuals with Type 2 Diabetes Mellitus with Preexisting Cardiovascular Disease: A 24‐Week, Multicenter, Randomized, Double‐Blind, Placebo‐Controlled Study with a 28‐Week Extension
Bibliographic record
Abstract
OBJECTIVES: To assess the efficacy of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, for the treatment of individuals with type 2 diabetes mellitus (T2DM) and preexisting cardiovascular disease (CVD). DESIGN: Randomized, double-blind, age-stratified (<65 and ≥ 65), 24-week clinical trial with a 28-week extension. SETTING: One hundred seventy-three centers in 10 countries. PARTICIPANTS: Individuals (N = 964) with T2DM, glycosylated hemoglobin (HbA1c) of 7.0% to 10.0%, and documented CVD. INTERVENTION: Dapagliflozin 10 mg/d or placebo was added to usual care. Participants receiving insulin had their total daily insulin dose reduced by 25% at randomization. MEASUREMENTS: Two equal primary end points: change from baseline in HbA1c and proportion of participants achieving a three-item end point (reduction of ≥ 0.5% in HbA1c, ≥ 3% in body weight, and ≥ 3 mmHg in systolic blood pressure) at 24 weeks. RESULTS: Forty-seven percent were aged 65 and older, 7.7% were aged 75 and older, mean duration of T2DM was 13 years, mean baseline HbA1c was 8.1%, and approximately 60% were taking insulin. The placebo-corrected change in HbA1c with dapagliflozin was -0.4% at 24 weeks. Significantly more participants achieved the three-item end point with dapagliflozin (10.0%) than with placebo (1.9%). The placebo-corrected percentage change in body weight for dapagliflozin was -1.9% (-1.8 kg). Similar results were observed in both age strata, and changes were maintained over 52 weeks. More than one-quarter (28.2%) of participants receiving dapagliflozin and 25.3% of those receiving placebo experienced hypoglycemia. More participants receiving dapagliflozin had vulvovaginitis, balanitis, or urinary tract infection. CONCLUSION: When added to a usual background regimen in an older population with advanced T2DM and preexisting comorbid CVD, dapagliflozin improved glycemic control without an increase in hypoglycemic risk, promoted weight loss, and was well tolerated.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
