Conditions
Summary
The purpose of this study is to assess the safety of atezolizumab and bevacizumab, or atezolizumab alone, as first-line treatment in participants with unresectable, locally advanced or metastatic hepatocellular carcinoma (HCC) with Child-pugh B7 or B8 cirrhosis.
Eligibility
Min Age: 18 Years
Inclusion Criteria16

- Disease that is not amenable to curative surgical and/or locoregional therapies
- No prior systemic treatment (including systemic investigational agents) for locally advanced or metastatic and/or unresectable HCC
- Measurable disease (at least one untreated target lesion) according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 within 7 days prior to initiation of study treatment
- Child-pugh B7 or B8 cirrhosis at screening and within 7 days prior to study treatment
- Adequate hematologic and end-organ function
- Life expectancy of at least 12 weeks
- Female participants of childbearing potential must be willing to avoid pregnancy and egg donation
- Absolute neutrophil count ≥1.0 x 10\^9 per liter (/L) (≥1000 per microliter \[/μL\]) without granulocyte colony-stimulating factor support
- Platelet count ≥ 50 × 109/L (50,000/μL) without transfusion
- Hemoglobin ≥ 80 grams per liter (g/L) (8 grams per deciliter \[g/dL\]) aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5 × upper limit of normal (ULN)
- Serum bilirubin ≤ 3 × ULN
- Creatinine clearance ≥ 50 milliliters per minute (mL/min) (calculated using the Cockcroft-gault formula)
- Serum albumin ≥ 20 g/L (2.0 g/dL) without transfusion in the prior 3 months
- International normalized ratio (INR) ≤2.3
Exclusion Criteria25
- Pregnancy or breastfeeding
- Prior treatment with cluster of differentiation 137 (CD137) agonists or immune checkpoint blockade therapies
- Treatment with investigational therapy within 28 days prior to initiation of study treatment
- Treatment with locoregional therapy to liver within 28 days prior to initiation of study treatment, or non-recovery from side effects of any such procedure
- Treatment with systemic immunostimulatory agents
- Treatment with systemic immunosuppressive medication
- Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment
- Inadequately controlled hypertension
- Active or history of autoimmune disease or immune deficiency
- History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan
- Participants who have a known concurrent malignancy that is progressing or requires active treatment, who have not completely recovered from treatment, or who have a significant malignancy history that, in the opinion of the investigator, should preclude participation
- Participants on preventative hormonal therapies (i.e., tamoxifen and other hormonal inhibitors) are not excluded
- Known fibrolamellar HCC, sarcomatoid HCC, other rare HCC variant, or mixed cholangiocarcinoma and HCC
- Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases
- Prior allogeneic stem cell or solid organ transplantation

- Co-infection with hepatitis B virus (HBV) and hepatitis C virus (HCV)
- Untreated or incompletely treated esophageal and/or gastric varices with bleeding or that are at high risk for bleeding
- A prior bleeding event due to esophageal and/or gastric varices within 6 months prior to initiation of study treatment
- Grade ≥3 hemorrhage or bleeding event within 6 months prior to initiation of study treatment
- Hepatic encephalopathy is allowed if no active symptoms or stable within 3 months of study treatment
- History, planned, or recommended placement of transjugular intrahepatic portosystemic shunt (TIPS) is excluded from Cohort A only. TIPS is acceptable in Cohort B
- Diagnostic paracentesis is allowed. Therapeutic paracentesis: one large volume paracentesis prior to enrollment with diuretic controlled ascites is allowed.
- Participants with ascites controlled on diuretics are allowed
- History of spontaneous bacterial peritonitis within last 12 months
