Multi-Center Study of the Effects of Simvastatin on Hepatic Decompensation and Death in Subjects Presenting With High-Risk Compensated Cirrhosis

Effect of Simvastatin on Hepatic Decompensation and Death in Subjects With High-risk Compensated Cirrhosis

This phase III, randomized, double-blind, placebo-controlled, multi-center study seeks to test whether simvastatin, a statin usually used to lower cholesterol to prevent heart problems and strokes, can lower the risk of hepatic decompensation (developing symptoms of cirrhosis) in U.S. Veterans who have compensated cirrhosis (the liver is scarred and damaged but there are no symptoms). The study will also explore how changes or differences in genes effect the safety and effectiveness of using statins and how the use of statins affects quality of life.

HMG-coA reductase inhibitors (statins), independent of cholesterol-lowering effects, are beneficial in liver diseases by reducing endothelial dysfunction, intrahepatic vasoconstriction, inflammation and fibrosis, and can reduce portal vein blood pressure. Clinically significant portal hypertension (hepatic vein wedge pressure greater than or equal to 10mmHg) is the most important predictor of decompensation and death in patients with cirrhosis.

This randomized, double-blind, placebo-controlled, multi-center Phase III interventional study seeks to demonstrate that statin therapy in patients with cirrhosis at high-risk for hepatic decompensation will reduce the incidence of hepatic decompensation, hepatocellular carcinoma or all-cause mortality.

Patients with compensated cirrhosis at high-risk for hepatic decompensation will be stratified based on the presence or absence of varices and randomized to simvastatin 40mg/day for up to 24 months. Patients will be observed for the development of hepatic decompensation (variceal hemorrhage, ascites, encephalopathy), hepatocellular carcinoma, liver-related death, death from any cause, and/or complications of statin therapy. Additionally, the interaction of SLCO1B1 and KIF6 polymorphisms on safety and clinical efficacy of statin therapy and the impact of statin exposure on health-related quality of life in patients with compensated cirrhosis will be examined.
