Conditions: Non Alcoholic Steatohepatitis

Healthy volunteers: yes

Brief summary:
The purpose of the study is to see if the drug ezetimibe is a potential treatment for Nonalcoholic Steatohepatitis(NASH).

Detailed description:
Nonalcoholic fatty liver disease (NAFLD) represents a spectrum of diseases ranging from simple steatosis to nonalcoholic steatohepatitis (NASH), the progressive form of liver disease that can lead to cirrhosis and liver-related mortality in persons who drink little or no alcohol. Nonalcoholic steatohepatitis (NASH) represents the more severe end of this spectrum and is characterized by steatosis, ballooning degeneration and lobular inflammation with or without fibrosis. The etiology of NASH is not completely understood, but it is often associated with obesity, type 2 diabetes, hyperlipidemia and insulin resistance. Lipotoxicity, insulin resistance and oxidative stress appear to be central to the pathogenesis of NASH. Currently, there is no FDA approved treatment for NAFLD/NASH. Weight loss and exercise are the recommended but often difficult maintain these lifestyle changes in the long term and therefore therapeutic agents have been investigated. Ezetimibe is an LDL lowering agent that works through inhibition of the fat absorption from the small intestine. In this study, we propose to treat 50 patients with NASH with either Ezetimibe or placebo for 24 weeks. After an initial evaluation for insulin sensitivity, MRI liver fat distribution and liver biopsy, patients will receive either 10 mg/day of Ezetimibe or placebo. Patients will be monitored at regular intervals for symptoms of liver disease, side effects of Ezetimibe and serum biochemical and metabolic indices. At the end of 24-weeks, patients will have a repeat medical evaluation, liver MRI and liver biopsy. Pre and post treatment MRI-derived liver fat content, liver histology and insulin sensitivity will be compared. The primary end point of successful therapy will be improvement in hepatic steatosis measured by MRI. Secondary end points will be improvement in insulin sensitivity, liver histology and liver biochemistry.
