Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Males and non-lactating, pregnancy test negative females between 18 - 80 years of age with biopsy proven F1 - F4 (compensated cirrhosis, Child-Pugh A, score ≤6) NASH. Limit F1 fibrosis to ≤ 20% of total subject population.
• Willingness to use appropriate contraceptive measures throughout study treatment and for 90 days thereafter (see Appendix A).
• Body mass index (BMI) > 23 kg/m2
• Must have confirmation of ≥ 5 % liver fat content on MRI-PDFF at screening.
• Biopsy-proven NASH confirmed by a central pathologist. Must have had a liver biopsy either during the screening period or a historical biopsy conducted within the last 6 months prior to pre-screening with fibrosis stage 1 to 4 (F score, F1-F4) and a non-alcoholic fatty liver disease (NAFLD) activity score (NAS) of ≥ 4 with at least a score of 1 in each of the following NAS components:
• Steatosis (scored 0 to 3),
• Ballooning degeneration (scored 0 to 2), and
• Lobular inflammation (scored 0 to 3).
• Must have no evidence of worsening of ALT and AST (within 50%) measurements within 2 months prior to screening (-8 weeks) visits.
• Screening laboratory parameters, as determined by the central laboratory:
• Estimated glomerular filtration rate (eGFR) ≥ 60 mL/min, as calculated by the Cockcroft- Gault equation;
• HbA1c ≤ 9.5% (or serum fructosamine ≤ 381 μmol if HbA1c is unable to be resulted);
• Hemoglobin ≥ 11 g/dL;
• INR ≤ 1.3, unless due to therapeutic anticoagulation;
• Direct bilirubin ≤ 0.5 mg/dL;
• Total bilirubin ≤ 1.3 x upper limit of normal (ULN), unless due to an alternate etiology such as Gilbert's syndrome or hemolytic anemia;
• Creatinine kinase < 3 x ULN;
• Platelet count ≥ 150,000/μL;
• Serum triglyceride level ≤ 500 mg/dL;
• ALT < 6 x ULN;
• AST < 6 x ULN;
• ALP < 2 x ULN.
• FibroScan® measurement > 7.0 kPa and < 20.0 kPa.
• Subjects on non-insulin dependent diabetic, weight loss, or lipid-modifying medication(s) must be on stable dose(s) for at least 3 months prior to the diagnostic liver biopsy through randomization.
• Subjects on vitamin E and pioglitazone must maintain a stable dosage before the diagnostic liver biopsy and during the study period.

You may not qualify if…

• Weight gain or loss > 5% in the 3 months prior to randomization or > 10% in the 6 months prior to screening.
• Type 1 and insulin-dependent Type 2 diabetes.
• Poorly controlled hypertension (blood pressure [BP] > 160/100 mmHg).
• Prior history of decompensated liver disease including ascites, hepatic encephalopathy (HE), or variceal bleeding.
• Chronic hepatitis B virus (HBV) infection (hepatitis B surface antigen [HBsAg] positive.
• Chronic hepatitis C virus (HCV) infection (HCV antibody [Ab] and HCV ribonucleic acid [RNA] positive). Subjects cured of HCV infection less than 1 year prior (based on date of RNA polymerase chain reaction [PCR] negative confirmation following conclusion of treatment) to the screening visit are not eligible.
• Prior or planned (during the study period) bariatric surgery (e.g., gastroplasty, roux-en-Y gastric bypass), surgery reversal or removal of intragastric balloon > 2 years prior to enrollment would be eligible.
• Other causes of liver disease based on medical history and/or centralized review of liver histology, including but not limited to alcoholic liver disease, autoimmune disorders (e.g., primary biliary cholangitis [PBC], primary sclerosing cholangitis [PSC], autoimmune hepatitis), drug-induced hepatotoxicity, Wilson disease, clinically significant iron overload, or alpha-1-antitrypsin deficiency requiring treatment.
• History of liver transplantation.
• Subjects with primary cancer, including co-existent second malignancy, with the exception of primary solid tumor with no known active disease present in the opinion of the Investigator which will not affect subject outcome in the setting of current diagnosis.
• Alcohol intake above an average limit of 2 drinks per day for women and 3 drinks per day for men. An alcoholic drink is defined as 12 ounces of regular beer, which is usually about 5% alcohol, 5 ounces of wine, which is typically about 12% alcohol, and 1.5 ounces of distilled spirits, which is about 40% alcohol.
• Human immunodeficiency virus (HIV) infection.
• Unstable cardiovascular disease in the 6 months prior to screening.
• Life expectancy less than 2 years.
• Use of any investigational medication within 30 days or within 5 half-lives of the investigational medication, whichever is longer, prior to screening and throughout the study is prohibited.
• Subjects with a history of (12 months prior to baseline) or current use of prescription drugs associated with liver steatosis (e.g., methotrexate, amiodarone, high-dose estrogen, tamoxifen, systemic steroids, anabolic steroids, valproic acid) should be excluded. However, subjects currently using silymarin should maintain their current dosage throughout the trial period.
• Contraindication of magnetic resonance imaging. These include but are not limited to devices or metal foreign bodies, such as Pacemaker, defibrillator or wires other than sternal wires, metallic foreign body in the eye, "triggerfish" contact lens, gastric reflux device, and insulin pumps.
• MELD score >12
• Subjects with esophageal or gastric varices with recent bleeding episodes (within 1 year).
