This is arandomized, open-label, multi-center, global,Phase IIIstudy to assess the efficacy and safety of durvalumab plus tremelimumab combination therapy and durvalumab monotherapy versus sorafenib in the treatment ofpatients with no prior systemic therapy for unresectable HCC. The patients cannot be eligible for locoregional therapy.
Patients will be randomized in a 1:1:1:1 ratio to durvalumab monotherapy (Arm 1), combination therapy with durvalumab plus tremelimumab regimen 1 (Arm 2), combination therapy with durvalumab plus tremelimumab regimen 2 (Arm 3), and sorafenib (Arm 4). Patients will be stratified according to macrovascular invasion (yes versus no), etiology of liver disease (hepatitis B virus [HBV] versus hepatitis C virus [HCV] versus others), and performance status (Eastern Cooperative Oncology Group [ECOG] 0 versus 1).
Durvalumab and tremelimumab will be administered via intravenous (IV) infusion every 4 weeks (Q4W). Sorafenib will be administered orally BID.
Patients in all treatment arms, should, wherever possible, continue to receive their initially assigned treatment to disease progression.
Patients in all treatment arms may continue receiving their originally assigned treatment, at the Investigator’s discretion, after the first overall time point assessment of progressive disease (PD) by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) until PD is confirmed on a follow-up scan (confirmed PD). A confirmatory scan is required following the assessment of PD by RECIST 1.1, preferably at the next scheduled visit and no earlier than 4 weeks after the previous assessment of PD. Patients in all arms with confirmed PD who, in the Investigator’s opinion, continue to receive benefit from their assigned treatment and meet the criteria for treatment in the setting of PD may continue to receive their assigned treatment. However, patients who develop progression in a target lesion after a clear response to therapy as defined by RECIST◦1.1 will not be permitted to continue therapy.
