• Current or recent (within 10 days prior to randomization) use of fulldose oral or parenteral anticoagulants or thrombolytic agents for therapeutic purpose. Prophylactic use of low molecularweight heparin is allowed.
• Female patients who are pregnant or breastfeeding, or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 90 days after the last dose of durvalumab monotherapy or 180 days after the last dose of durvalumab plus tremelimumab combination therapy or bevacizumab therapy
• Prior randomization or treatment in a previous durvalumab and/or tremelimumab clinical study regardless of treatment arm assignment.

Egyéb

• Clinically meaningful ascites
• Known fibrolamellar HCC, sarcomatoid HCC, or mixed cholangiocarcinoma and HCC.

• Age ≥18 years at the time of study entry
• Confirmed HCC based on histopathological findings from tumor tissues.
• Must not have received prior systemic therapy for HCC.
• Not eligible for locoregional therapy for unresectable HCC. For patients who progressed after locoregional therapy for HCC, locoregional therapy must have been completed ≥28 days prior to the baseline scan for the current study.
