Aleglitazar (R1439) is a dual peroxisome proliferator-activated receptor (PPAR) agonist, with affinity to PPARα and PPARγ. Aleglitazar is being developed for the treatment of type II diabetes; It is currently in phase III clinical trials. In preliminary clinical studies, Aleglitazar has been demonstrated to improve hyperglycemia and dyslipidemia in patients with type 2 diabetes mellitus. Aleglitazar has beneficial effects on both lipid and glucose parameters and may have a therapeutic role in modifying cardiovascular risk factors and improving glycemic control in patients with T2DM. Aleglitazar combines the lipid benefits of fibrates and the insulin-sensitizing benefits of thiazolidinediones.
