Canagliflozin and Cardiovascular disease- results of the CANVAS trial

Abstract

Canagliflozin is a new novel oral antidiabetic agent belonging to the class of sodium-glucose co-transporter 2 (SGLT2) inhibitors, inhibiting glucose reabsorption in the proximal tubule, leading to increased urinary glucose excretion and subsequently to reduction in plasma glucose concentration, in individuals with hyperglycemia. Before the approval of canagliflozin by the Food and Drug Administration (FDA) in 2013, a pair-wise meta-analyses of trials involving canagliflozin did not differ from control in terms of all-cause mortality, cardiovascular death, myocardial infarction, and stroke. However, no large, randomized-controlled trials were available for comparison until the results of the CANVAS (Canagliflozin Cardiovascular Assessment Study) trial were published. The CANVAS Trial was designed to assess the cardiovascular safety and efficacy of canagliflozin. Recently, results of the completed CANVAS Trial were released which showed patients with type 2 diabetes and established cardiovascular disease or at high risk for cardiovascular events who were treated with canagliflozin had significantly lower rates of the primary cardiovascular outcome than patients assigned to placebo. All three components of the primary outcome - death from cardiovascular causes, nonfatal myocardial infarction, and nonfatal stroke - showed point estimates of effect that suggested benefit .These results may represent a significant additional therapeutic tool in the clinical prevention and management of cardiovascular mortality and morbidity. However, data on the long-term efficacy on the use of Canagliflozin is still incomplete and their use in patients with type 2 diabetes should be carefully considered.
