• Chronic liver disease from any other cause including, but not limited to, alcoholic liver disease; evidence of portal hypertension; viral hepatitis or any history or evidence of cirrhosis on screening liver biopsy; or decompensated liver disease such as clinical ascites, bleeding gastroesophageal varices, hepatorenal syndrome, or hepatic encephalopathy prior to Screening or Day 1
• Current or history of excessive alcohol intake for >=3 months within the 12-month period prior to Screening
• Model for End-Stage Liver Disease score >=12 unless the score is elevated in the absence of liver dysfunction (e.g., Gilbert's syndrome)
• Evidence of infection with any of the following:; Human immunodeficiency virus; Hepatitis B virus (detectable HBsAg at Screening); Hepatitis C virus (HCV)
• ALT or AST >=5 x upper limit of normal (ULN)
• Total bilirubin >=1.3 milligram per deciliter (mg/dL). Individuals with documented Gilbert's syndrome may be enrolled if they experienced an isolated increase in total bilirubin of >=1.3 mg/dL and direct bilirubin is <=20% of total bilirubin; otherwise, the individual will be excluded

• Platelet (PLT) count <140,000 per (/) cubic millimeter (mm\^3); individuals with a PLT count between 110,000/mm\^3 and 140,000/mm\^3 may be enrolled after discussion with the Study Medical Monitor
• Serum creatinine >=1.5 mg/dL or creatinine clearance <=60 milliliter (mL)/minute (min)/1.73 square meter by Chronic Kidney Disease Epidemiology Collaboration equation
• Glycated hemoglobin >=9.0%
• Contraindication or ineligibility for percutaneous liver biopsy
• Alpha-fetoprotein >=20 nanogram per milliliter (ng/mL)
• Phosphatidyl ethanol (PEth) >=80 ng/mL at Screening
