Class effect for SGLT-2 inhibitors: a tale of 9 drugs

Abstract

Abstract The definition of class effect for SGLT-2 inhibitors may be based on three concepts: a similar chemical structure, a similar mechanism of action and similar pharmacological effects. We have also assumed that a class effect does exist when an effect on a particular outcome is present and is significant for each drug within the class of SGLT-2 inhibitors. For major cardiovascular events (MACE), there is no class effect for SGLT-2 inhibitors, as the 7% reduction of MACE risk observed with dapagliflozin in the DECLARE trial was not significant; on the other hand, a class effect is evident for both heart failure and diabetic kidney disease, as in all four trials so far completed (EMPAREG-OUTCOME, CANVAS, DECLARE, CREDENCE) the risk of hospitalization for heart failure and progression of diabetic kidney disease was significantly reduced by all SGLT-2 inhibitors.
