Patient description: The patient is a 55-year-old man diagnosed with HCV 2 years ago and the recent coinfection with HBV. His past medical history is non-significant. He is on IFN, RBV and direct antiviral drugs for the past 6 months. The patient takes no other medications. His medical records show previous positive HCV RNA tests and a positive enzyme immunoassay for anti-HCV-antibodies. The recent biopsy was negative for hepatocellular carcinoma and was only remarkable for chronic inflammation compatible with a chronic viral hepatitis. There is no evidence of alcoholic liver disease, bleeding from esophageal varices, hemochromatosis, autoimmune hepatitis, or metabolic liver disease. He is an alert male with no acute distress. His BP: 130/75, HR: 90/min and BMI: 27. His abdomen is soft with no ascites or tenderness. The lower extremities are normal with no edema.

Prior chemotherapy given locally into the liver (e.g. transarterial chemoembolization [TACE]) is allowed Must have Child-Pugh class A hepatic function within 7 days prior to first dose of study intervention Eastern Cooperative Oncology Group (ECOG) performance status 0-1  Prior treatment with any systemic therapy for HCC, including anti-VEGF therapy or any systemic investigational agent If the patient previously received systemic treatment for reasons other than HCC: small molecule kinase inhibitors are not allowed within 2 weeks and cytotoxic/biologic agents are not allowed within 4 weeks of study treatment Prior exposure to immune checkpoint inhibitors or other immunotherapeutic agents Currently participating in or has participated in a study of an investigational agent or device within 4 weeks prior to the first dose of study treatment Major surgery within 6 weeks or minor surgery (e.g. dental extraction) within 10 days prior to first dose of study treatment Complete wound healing from major surgery must have occurred at least 1 month before first dose and from minor surgery (e.g. simple excision, tooth extraction) at least 7 days before first dose. Subjects with clinically relevant ongoing complications from prior surgery are not eligible Local liver-directed therapy within 4 weeks of initiating study treatment Palliative radiation for the purpose of symptomatic relief to non-liver and non-central nervous system (CNS) disease within 2 weeks of starting treatment. Other radiation treatments within 4 weeks of starting treatment Patients must have recovered from all radiation-related toxicities, not require corticosteroids, and have not had radiation pneumonitis Prior liver or other allogenic tissue/organ transplantation
