The primary objectives of this study are: - To assess the safety and tolerability of selonsertib (SEL), firsocostat, and cilofexor, administered alone or in combination, in participants with bridging fibrosis or compensated cirrhosis due to Nonalcoholic Steatohepatitis (NASH) - To evaluate changes in liver fibrosis, without worsening of NASH

Official Title

A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Safety and Efficacy of Selonsertib, Firsocostat, Cilofexor, and Combinations in Subjects With Bridging (F3) Fibrosis or Compensated Cirrhosis (F4) Due to Nonalcoholic Steatohepatitis (NASH)


Nonalcoholic Steatohepatitis Fatty Liver Non-alcoholic Fatty Liver Disease SEL Firsocostat Cilofexor


For people ages 18-80

Key Inclusion Criteria:

  • Liver biopsy consistent with NASH and bridging fibrosis (F3) and cirrhosis (F4) in the opinion of the central reader
  • In participants who have never had a liver biopsy, liver stiffness by FibroScan® and Enhanced Liver Fibrosis (ELF™) Test score at Screening
  • 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%
  • Alanine aminotransferase (ALT) < 5 x Upper Limits of Normal (ULN)
  • Platelet count ≥ 125,000/μL

Key Exclusion Criteria:

  • Prior history of decompensated liver disease including ascites, hepatic encephalopathy, or variceal bleeding
  • Child-Pugh (CP) score > 6 at Screening, unless due to an alternative etiology such as Gilbert's syndrome or therapeutic anticoagulation
  • Model for End-Stage Liver Disease (MELD) score > 12 at Screening, unless due to an alternate etiology such as therapeutic anticoagulation
  • Other causes of liver disease based on medical history and/or centralized review of liver histology, including but not limited to: alcoholic liver disease, hepatitis B, hepatitis C, autoimmune disorders (eg, primary biliary cholangitis, primary sclerosing cholangitis, autoimmune hepatitis), drug-induced hepatotoxicity, Wilson disease, clinically significant iron overload, or alpha-1-antitrypsin deficiency requiring treatment
  • History of liver transplantation
