Rationale & Objective: Canagliflozin reduces the risk for cardiovascular and kidney outcomes in type 2 diabetes. This study aimed to assess the relative and absolute effects of canagliflozin on clinical outcomes across different KDIGO (Kidney Disease: Improving Global Outcomes) risk categories based on estimated glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio. Study Design: Post hoc analysis of the CANagliflozin cardioVascular Assessment Study (CANVAS) Program. Settings & Participants: The CANVAS Program randomly assigned 10,142 participants with type 2 diabetes at high cardiovascular risk and with eGFR ≥ 30 mL/min/1.73 m2 to treatment with canagliflozin or placebo. Intervention(s): Canagliflozin or matching placebo. Outcomes: The primary outcome was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke, with a set of other cardiovascular and kidney prespecified outcomes. Results: Of 10,142 participants, 10,031 (98.9%) had available baseline eGFR and urinary albumin-creatinine ratio data. The proportion of participants in low-, moderate-, high-, and very high–risk KDIGO categories was 58.6%, 25.8%, 10.6%, and 5.0%, respectively. The relative effect of canagliflozin on the primary outcome (HR, 0.86; 95% CI, 0.75-0.97) was consistent across KDIGO risk categories (P trend = 0.2), with similar results for other cardiovascular and kidney outcomes. Absolute reductions in the primary outcome were greater within higher KDIGO risk categories (P trend = 0.03) with a similar pattern of effect for the composite of cardiovascular death or hospitalization for heart failure (P trend = 0.06) and for chronic eGFR slope (P trend = 0.04). Limitations: Predominantly a low kidney risk population, relatively few participants in higher KDIGO risk categories, and exclusion of individuals with eGFR < 30 mL/min/1.73 m2. Conclusions: Although the relative effects of canagliflozin are similar across KDIGO risk categories, absolute risk reductions are likely greater for individuals at higher KDIGO risk. The KDIGO classification system may be able to identify individuals who might derive greater benefits for end-organ protection from treatment with canagliflozin. Funding: This post hoc analysis was not specifically funded. The original CANVAS Program trials were funded by Janssen Research & Development, LLC and were conducted as a collaboration between the funder, an academic steering committee, and an academic research organization, George Clinical. Trial Registration: The original trials of the CANVAS Program were registered at with study numbers NCT01032629 and NCT01989754.
