Resum
Caspases play a central role in apoptosis, inflammation and fibrosis. They produce hemodynamically-active, pro-inflammatory microparticles that cause intrahepatic inflammation, vasoconstriction and extrahepatic splanchnic vasodilation. Emricasan is a pan-caspase inhibitor that lowers portal hypertension (PH) and improves survival in murine models of cirrhosis. This exploratory study assessed whether emricasan lowers PH in patients with compensated cirrhosis. This multicenter, open-label study enrolled 23 subjects with compensated cirrhosis and PH (HVPG >5 mmHg). Emricasan 25 mg BID was given for 28 days. HVPG measurements were standardized and performed before and after emricasan. A single expert read all HVPG tracings.Median age was 59 (range 49-80); 70% were male. Cirrhosis etiologies were NASH and HCV. Subjects were Child class A (87%) with median MELD score of 8 (range 6-15). Twelve had severe PH (HVPG?12mmHg). Overall, there was no significant change in HVPG after emricasan (mean [SD] -1.1[4.57] mmHg). HVPG decreased significantly (mean [SD] -3.7[4.05] mmHg; p=0.003) in those with severe PH. 4/12 had a ?20% decrease; 8/12 had a ?10% decrease; and 2/12 HVPG decreased below 12mmHg. There were no significant changes in blood pressure or heart rate. AST/ALT decreased significantly in the entire group and in severe PH. Serum cCK18 and caspase-3/7 decreased significantly. Emricasan was well-tolerated. One subject discontinued for non-serious adverse events.Emricasan administered for 28 days decreased HVPG in patients with compensated cirrhosis and severe PH. An effect upon portal venous inflow is likely and concomitant decreases in AST/ALT suggest an intrahepatic anti-inflammatory effect.
