This is a randomized, open-label, multi-center, global, Phase III study to assess the efficacy and safety of durvalumab plus tremelimumab combination therapy and durvalumab monotherapy versus sorafenib in the treatment of patients with no prior systemic therapy for unresectable HCC. The patients cannot be eligible for locoregional therapy.

Official Title

A Randomized, Open-label, Multi-center Phase III Study of Durvalumab and Tremelimumab as First-line Treatment in Patients With Unresectable Hepatocellular Carcinoma


The study population includes patients 18 years of age or older with unresectable HCC, Barcelona Clinic Liver Cancer stage B not eligible for locoregional therapy or stage C, and Child-Pugh A classification liver disease. Patients must not have received any prior systemic therapy for unresectable HCC.

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)

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.

If a patient discontinues study drug(s) due to disease progression, the patient will enter survival follow-up. Patients who have discontinued treatment due to toxicity or symptomatic deterioration or who have commenced subsequent anticancer therapy, will have tumor assessments until confirmed PD and will be followed for survival.
