• Confirmation of chronic HCV infection documented by at least one measurement of serum HCV RNA above the LLOQ measured at screening, and at least one of the following:
• Positive anti-HCV antibody test, HCV RNA or HCV genotyping test at least 6 months prior to the baseline/Day 1 visit together with positive HCV RNA test and anti-HCV antibody at the time of screening, or
• Positive HCV RNA test and anti-HCV antibody test at the time of screening together with either a liver biopsy consistent with chronic HCV infection (or a liver biopsy performed before enrollment with evidence of chronic HCV infection, such as the presence of fibrosis)
• HCV RNA > 10^4 IU/mL at screening
• Patients meeting the MILAN criteria undergoing liver transplant for HCC secondary to HCV with a MELD of 10 mg/day) in the pretransplant treatment period.

• Evidence of renal impairment (CLcr < 60 mL/min) calculated by the Cockcroft-Gault equation.
• History or current evidence of psychiatric illness, immunologic disorder, hemoglobinopathy, pulmonary or cardiac disease, porphyria, or poorly controlled diabetes, cancer other than HCC, or a history of malignancy that in the opinion of the investigator makes the patient unsuitable for the study.

• History of having received any systemic antineoplastic (including sorafenib) or immunomodulatory treatment (including radiation) within 6 months prior to the first dose of study drug or the expectation that such treatment will be needed at any time during the study (excluding a local regional therapy such as TACE).
• Treatment with Transcatheter arterial chemoembolization (TACE) or radio frequency ablation (RFA) within 30 days prior to the first dose.
