About this trial
Subjects with biopsy-proven NASH will be randomly assigned in a 2:1 ratio to oral doses of namodenoson 25 mg every 12 hours or matching placebo every 12 hours for 36 weeks. Subjects will be evaluated regularly for safety, and efficacy biomarkers will be measured at Baseline and Weeks 6, 12, 24, and 36. At Week 36, all subjects will undergo liver biopsy.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
At least 18 years of age.
AST at Screening of ≥20 IU/L.
FibroScan LSM ≥8.5 kPa
Diagnosis of NASH by biopsy at Screening showing NAS ≥4 by central read, with a score of at least 1 point in each of the 3 histologic categories of steatosis, inflammation, and hepatocellular ballooning (Kleiner 2005). If the subject has had a qualifying liver biopsy within 6 months prior to Baseline and the slides are available for central read prior to randomization, this biopsy can be waived.
Disqualifiers
Ascites, hepatic encephalopathy, or other clinical evidence of cirrhosis.
Other active acute or chronic liver disease, such as autoimmune hepatitis, hepatitis B, hepatitis C, alcoholic liver disease, or hepatocellular carcinoma.
Seropositivity for markers of viral hepatitis or human immunodeficiency virus (HIV) at Screening.
Weight loss of >5% within 3 months prior to Baseline.
