In 2008 the Food and Drug Administration has revised approval process for new antidiabetic agents and introduced a requirement to demonstrate the cardiovascular safety in an international multicenter trial. Currently cardiovascular outcome trials of dipeptidyl peptidase-4 (DPP-4) inhibitors (SAVOR-TIMI53, EXAMINE and TECOS), sodium-glucose cotransporter 2 inhibitors (EMPAREG, CANVAS), glucagon-like peptide-1 receptor agonists (ELIXA, EXSCEL LEADER and SUSTAIN-6), ultralong-acting and insulin (DEVOTE) have been completed. The trials confirmed cardiovascular safety of these glucose-lowering medications, and in addition, EMPA-REG OUTCOME (empagliflozin), CANVAS (canagliflozin) and LEADER (liraglutide) have also demonstrated cardioprotective effect of sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists. These data led to the changes of clinical guidelines for the management of type 2 diabetes.
