Impact of Canagliflozin on Kidney and Cardiovascular Outcomes by Type 2 Diabetes Duration: A Pooled Analysis of the CANVAS Program and CREDENCE Trials.

Abstract

The study was undertaken because it was unknown whether the duration of type 2 diabetes modifies the effects of sodium-glucose cotransporter 2 inhibitor canagliflozin on cardiovascular (CV) and kidney outcomes. This post hoc analysis of the Canagliflozin Cardiovascular Assessment Study (CANVAS) Program (N = 10,142) and Evaluation of the Effects of Canagliflozin on Renal and Cardiovascular Outcomes in Participants With Diabetic Nephropathy (CREDENCE) trial (N = 4,401) evaluated hazard ratios and 95% CIs using Cox proportional hazards for the effects of canagliflozin on CV and kidney outcomes, including progression and regression of albuminuria over 5-year intervals of disease duration. Canagliflozin had ranges of benefit across intervals of diabetes duration, with no heterogeneity for major adverse CV events, CV death or heart failure hospitalization, and kidney failure requiring therapy or doubling serum creatinine. Furthermore, canagliflozin reduced albuminuria progression and increased albuminuria regression with no interaction across all diabetes duration subgroups. Our findings suggest that earlier treatment with canagliflozin confers consistent cardiorenal benefits to individuals with type 2 diabetes.
