OBJECTIVE This study assessed the efficacy/safety of canagliflozin (CANA), a sodium–glucose cotransporter 2 (SGLT2) inhibitor, plus metformin extended-release (MET) initial therapy in drug-naïve type 2 diabetes. RESEARCH DESIGN AND METHODS This 26-week, double-blind, phase 3 study randomized 1,186 patients to CANA 100 mg (CANA100)/MET, CANA 300 mg (CANA300)/MET, CANA100, CANA300, or MET. Primary end point was change in HbA1c at week 26 for combinations versus monotherapies. Secondary end points included noninferiority in HbA1c lowering with CANA monotherapy versus MET; changes in fasting plasma glucose, body weight, and blood pressure; and proportion of patients achieving HbA1c <7.0% (<53 mmol/mol). RESULTS From mean baseline HbA1c of 8.8% (73 mmol/mol), CANA100/MET and CANA300/MET significantly lowered HbA1c versus MET (median dose, 2,000 mg/day) by –1.77%, –1.78%, and –1.30% (–19.3, –19.5, and –14.2 mmol/mol; differences of -0.46% and –0.48% [–5.0 and –5.2 mmol/mol]; P = 0.001) and versus CANA100 and CANA300 by –1.37% and –1.42% (–15.0 and –15.5 mmol/mol; differences of –0.40% and –0.36% [–4.4 and –3.9 mmol/mol]; P = 0.001). CANA100 and CANA300 monotherapy met noninferiority for HbA1c lowering and had significantly more weight loss versus MET (–2.8, –3.7, and –1.9 kg [–3.0%, –3.9%, and –2.1%]; P = 0.016 and P = 0.002). Greater attainment of HbA1c <7.0% (50%, 57%, and 43%) and significantly more weight loss (–3.2, –3.9, and –1.9 kg [–3.5%, –4.2%, and –2.1%]; P = 0.001) occurred with CANA100/MET and CANA300/MET versus MET. The incidence of adverse events (AEs) related to SGLT2 inhibition (genital mycotic infections, osmotic diuresis– and volume depletion–related AEs) was higher in the CANA arms (0.4–4.4%) versus MET (0–0.8%). AE-related discontinuation rates were 1.3–3.0% across groups. The incidence of hypoglycemia was 3.0–5.5% in the CANA arms and 4.6% with MET. CONCLUSIONS Initial therapy with CANA plus MET was more effective and generally well tolerated versus each monotherapy in drug-naïve type 2 diabetes. CANA monotherapy demonstrated noninferior HbA1c lowering versus MET.
