• Hepatitis C antibody (HCVAb) positive with the following 2 exceptions:

  1. Participants previously treated for viral hepatitis C with at least a 1-year period since documented sustained virologic response at Week 12 (post-treatment) may be eligible if all other eligibility criteria are met
  2. Participants with presence of hepatitis C antibody but negative hepatitis C virus ribonucleic acid RNA without treatment (i.e., spontaneous clearance) may be eligible if all other eligibility criteria are met

• Prior or planned liver transplantation

• Other known causes of chronic liver disease, including alcoholic liver disease

• History of cirrhosis and/or hepatic decompensation including ascites, hepatic encephalopathy or variceal bleeding

• Alcohol consumption greater than 21 units/week for males or 14 units/week for females (one unit of alcohol is ½ pint of beer [285 mL], 1 glass of spirits [25 mL] or 1 glass of wine [125 mL])

• Human immunodeficiency virus (HIV)-1 or HIV-2 infection

• Weight reduction through bariatric surgery in the past 5 years or planned during the conduct of the study (including gastric banding)
