Canagliflozin Compared With Sitagliptin for Patients With Type 2 Diabetes Who Do Not Have Adequate Glycemic Control With Metformin Plus Sulfonylurea

Abstract

OBJECTIVETo evaluate the efficacy and safety of canagliflozin, a sodium glucose cotransporter 2 inhibitor, compared with sitagliptin in subjects with type 2 diabetes inadequately controlled with metformin plus sulfonylurea.RESEARCH DESIGN AND METHODSIn this 52-week, randomized, double-blind, active-controlled, phase 3 study, subjects using stable metformin plus sulfonylurea (N = 755) received canagliflozin 300 mg or sitagliptin 100 mg daily. Primary end point was change from baseline in A1C at 52 weeks. Secondary end points included change in fasting plasma glucose (FPG) and systolic blood pressure (BP), and percent change in body weight, triglycerides, and HDL cholesterol. Safety was assessed based on adverse event (AE) reports.RESULTSAt 52 weeks, canagliflozin 300 mg demonstrated noninferiority and, in a subsequent assessment, showed superiority to sitagliptin 100 mg in reducing A1C (−1.03% [−11.3 mmol/mol] and −0.66% [−7.2 mmol/mol], respectively; least squares mean difference between groups, −0.37% [95% CI, −0.50 to −0.25] or −4.0 mmol/mol [−5.5 to −2.7]). Greater reductions in FPG, body weight, and systolic BP were observed with canagliflozin versus sitagliptin (P < 0.001). Overall AE rates were similar with canagliflozin (76.7%) and sitagliptin (77.5%); incidence of serious AEs and AE-related discontinuations was low for both groups. Higher incidences of genital mycotic infections and osmotic diuresis–related AEs were observed with canagliflozin, which led to one discontinuation. Hypoglycemia rates were similar in both groups.CONCLUSIONSFindings suggest that canagliflozin may be a new therapeutic tool providing better improvement in glycemic control and body weight reduction than sitagliptin, but with increased genital infections in subjects with type 2 diabetes using metformin plus sulfonylurea.

Effect of Sodium‐Glucose Cotransport‐2 Inhibitors on Blood Pressure in People With Type 2 Diabetes Mellitus: A Systematic Review and Meta‐Analysis of 43 Randomized Control Trials With 22 528 Patients

“…Data were sorted by first author, year of publication, country of the study, design, age range of the participants, total sample size, SGLT2 inhibitor, comparator, number of patients, dosage, and follow‐up duration (Table 1). 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55 …”

Tolerability of canagliflozin in patients with type 2 diabetes mellitus fasting during Ramadan: Results of the Canagliflozin in Ramadan Tolerance Observational Study (CRATOS)

“…While the insulin‐independent mechanism of canagliflozin leads to a low inherent risk of hypoglycaemia, the mild osmotic diuresis it causes may be associated with an increased risk of volume–depletion events, including dehydration. Across Phase 3 studies in a broad range of patients, canagliflozin provided reductions in HbA1c, body weight, and systolic blood pressure (BP) and was generally well tolerated, with a low risk of hypoglycaemia when not used in conjunction with insulin or sulphonylureas 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22. An analysis of T2DM patients living in hot climates found that canagliflozin treatment was generally well tolerated, with a low incidence of volume depletion–related AEs 23…”

Bioequivalence of Canagliflozin/Metformin Immediate Release Fixed- Dose Combination Tablets Compared with Concomitant Administration of Single Components of Canagliflozin and Metformin in Healthy Fed Participants

“…and 300 mg QD and were on stable metformin therapy at ≥2,000 mg/ day or ≥1,500 mg/day if unable to tolerate a higher dose [26,33,34]. In a drug-drug interaction study, healthy participants received single daily oral doses of canagliflozin 300 mg and metformin 2,000 mg, and no clinically meaningful interaction between the pharmacokinetics of either drug was observed suggesting that the two drugs could be combined into a single FDC tablet [35].…”
