SGLT2 inhibitors have favorable effects on glycemia, blood pressure, body weight, intrarenal hemodynamics, and albuminuria, and they may also reduce the risk of serious CV complications, kidney disease, and death [1-3].

The CANVAS program consisted of 2 studies: The Canagliflozin Cardiovascular Assessment Study (CANVAS) was set up to evaluate CV safety, including kidney and other safety outcomes, such as genitourinary infection, diabetic ketoacidosis, and fracture. CANVAS–Renal (CANVAS-R) was designed as a second CANVAS-like trial with similar design to CANVAS, to be analyzed jointly with CANVAS, to meet a post-approval CV safety commitment to regulatory agencies. CANVAS-R therefore also assessed effects on albuminuria.

This is an integrated analysis of CANVAS (n=4330) and CANVAS-R (n=5812) on data of T2DM patients with elevated CV risk, randomized to canagliflozin (300 or 100 mg in CANVAS, 100 mg in CANVAS-R) or placebo, in addition to background therapy [4-6]. Patients were followed for a mean of 295.9 weeks in CANVAS and 108.0 weeks in CANVAS-R.

Main results


In the CANVAS trial program, diabetic patients with elevated CV risk treated with canagliflozin had a significantly lower risk of CV death, non-fatal MI, or non-fatal stroke compared with those who received placebo, but a higher risk of amputation and fractures.
