A Study to Test the Effectiveness and Safety of Experimental VK2809 for Biopsy Proven Non-Alcoholic Steatohepatitis (NASH)

Open to people ages 18-75

1. Provide a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study and is willing and able to participate;
2. Have a histologically-confirmed diagnosis of NASH on a liver biopsy performed during screening or within 6 months before screening; for this study, confirmation requires:
   1. NASH Clinical Research Network (CRN) fibrosis stage 1 to stage 3 and
   2. NASH activity score (NAS) of ≥4 with at least a score of 1 in each of the following NAS components: ballooning degeneration (score = 0-2), lobular inflammation (score = 0-3) and steatosis (score = 0-3); (c) F1 subjects must have at least one of these risk factors: type 2 diabetes, body mass index of ≥ 30 mg/ m2, and/ or alanine aminotransferase > 1.5 x ULN
3. Have a screening MRI-PDFF with ≥ 8% liver fat fraction;
4. Male and females be 18 to 75 years of age, inclusive, at screening;

1. Are unwilling to undergo the required liver biopsy procedures or have any condition that would prevent obtaining a liver biopsy as part of this clinical protocol
2. Have evidence of current or history of excessive alcohol consumption of more than 20 g per day for women and 30 g per day for men, on average, within 6 months before the qualifying liver biopsy and up to randomization, or are unable to provide a reliable estimate of alcohol consumption during this period;
3. Treatment with medications for the purpose of weight loss within 6 months prior to qualifying liver biopsy, unless approved after consultation with the medical monitor. These include drugs approved for weight loss (e.g. orlistat, bupropion/naltrexone, phentermine-topiramate, phentermine, lorcaserin), as well as drugs used off-label, herbal preparations and dietary supplements marketed for control of body weight or appetite;
4. TSH outside central laboratory reference range;
5. Free T4 outside central laboratory reference range;
6. Cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) > Upper Limit of Normal (ULN) at screening;
7. Serum albumin < 3.5 g/dL;
8. International normalized ratio (INR) > 1.3;
9. Total bilirubin > 1.2 X ULN (except in presence of Gilbert synd
10. Strong or moderate inhibitors or inducers of CYP3A4 are prohibited during the study period
11. Drugs that may affect liver fat content or are associated with nonalcoholic fatty liver disease (NAFLD) are prohibited during the 3 month period prior to the baseline liver biopsy and up to the end of treatment
