Canagliflozin Provides Durable Glycemic Improvements and Body Weight Reduction Over 104 Weeks Versus Glimepiride in Patients With Type 2 Diabetes on Metformin: A Randomized, Double-Blind, Phase 3 Study
Bibliographic record
Abstract
OBJECTIVE: To assess the efficacy/safety of canagliflozin, a sodium-glucose cotransporter 2 inhibitor, compared with glimepiride over 104 weeks in patients with type 2 diabetes inadequately controlled with metformin. RESEARCH DESIGN AND METHODS: In this randomized, double-blind study, patients (N = 1,450) received canagliflozin 100 or 300 mg or glimepiride (titrated up to 6 or 8 mg/day) during a 52-week core period followed by a 52-week extension. RESULTS: At week 104, reductions from baseline in A1C were -0.65%, -0.74%, and -0.55% (-7.1, -8.1, and -6.0 mmol/mol) with canagliflozin 100 and 300 mg and glimepiride, respectively. Durability analyses showed sustained A1C lowering with both canagliflozin doses versus glimepiride. Reductions in body weight (-4.1%, -4.2%, and 0.9%, respectively) and systolic blood pressure (-2.0, -3.1, and 1.7 mmHg, respectively) were seen with canagliflozin 100 and 300 mg compared with glimepiride at week 104. The overall adverse event (AE) incidence was 73.3%, 77.9%, and 78.4% with canagliflozin 100 and 300 mg and glimepiride; the incidence of AE-related discontinuations was low across groups (6.2%, 9.5%, and 7.3%, respectively). Incidences of genital mycotic infections, urinary tract infections, and osmotic diuresis-related AEs were higher with canagliflozin than glimepiride; these were generally mild to moderate in intensity and led to few discontinuations. Fewer patients had hypoglycemia episodes with canagliflozin 100 and 300 mg than glimepiride (6.8%, 8.2%, and 40.9%). Mild decreases in estimated glomerular filtration rate occurred initially with canagliflozin; these attenuated over 104 weeks. CONCLUSIONS: Canagliflozin provided durable glycemic improvements compared with glimepiride and was generally well tolerated in patients with type 2 diabetes receiving background treatment with metformin over 104 weeks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
