SGLT2 inhibitors are approved for glucose lowering in type 2 diabetes (T2DM) and have proven CV benefits, but are not approved for people with significantly reduced kidney function as glycemic efficacy is dependent on glomerular filtration. This analysis of the CANagliflozin cardioVascular Assessment Study (CANVAS) Program assessed effects of canagliflozin on CV outcomes in T2DM according to kidney function (estimated glomerular filtration rate [eGFR] <45, 45-<60, 60-<90, and ≥90 ml/min/1.73 m2). The CANVAS Program included 2039 patients (20.1%) with baseline eGFR <60 ml/min/1.73 m2 (mean age 68 y, BP 138/76 mmHg, HbA1c 8.3%, eGFR 49 ml/min/1.73 m2, median urinary albumin:creatinine ratio 22 mg/g). Effects of canagliflozin on HbA1c and body weight were smaller in patients with eGFR <60 vs. ≥60; ml/min/1.73 m2 (-0.43 vs. -0.64%, P-heterogeneity <0.0001, and -1.16 vs. -1.43 kg, P-heterogeneity = 0.0002), but BP effects were similar (-3.89 vs. -4.11 mmHg, P-heterogeneity = 0.21). Relative effects on the primary and most other CV outcomes were similar across four eGFR subgroups, with possible heterogeneity suggested only for the exploratory outcome of stroke (Figure). Results for almost all safety outcomes were also consistent across eGFR subgroups. Despite smaller glycemic effects in people with reduced eGFR, the cardioprotective benefits of canagliflozin are similar across different levels of kidney function.
