Emricasan, also known as IDN 6556 and PF 03491390, is a first-in-class caspase inhibitor in clinical trials for the treatment of liver diseases. Emricasan (IDN-6556) decreases liver injury and fibrosis in a murine model of non-alcoholic steatohepatitis. IDN6556 facilitates marginal mass islet engraftment in a porcine islet autotransplant model. Oral IDN-6556 may lower aminotransferase activity in patients with chronic hepatitis C. Orally-administered PF-03491390 is retained in the liver for prolonged periods with low systemic exposure, exerting a hepatoprotective effect against alpha-fas-induced liver injury in a mouse model.
