Brief Summary:
This Phase 3 study evaluates the safety and efficacy of cabozantinib in combination with atezolizumab versus the standard of care sorafenib in adults with advanced hepatocellular carcinoma (HCC) who have not received previous systemic anticancer therapy. A single-agent cabozantinib arm will be enrolled in which subjects receive single agent cabozantinib in order to determine its contribution to the overall safety and efficacy of the combination with atezolizumab.

Condition or disease Intervention/treatment Phase
Hepatocellular Carcinoma Drug: Cabozantinib Drug: Sorafenib Drug: Atezolizumab Phase 3

Detailed Description:
This is a multicenter, randomized, open-label, controlled Phase 3 trial of cabozantinib in combination with atezolizumab versus sorafenib in adults with advanced HCC who have not received previous systemic anticancer therapy in the advanced HCC setting. The primary objective of this study is to evaluate the effect of cabozantinib in combination with atezolizumab on the duration of progression-free survival (PFS) and duration of overall survival (OS) versus sorafenib. The secondary objective is to evaluate the activity of single-agent cabozantinib compared with sorafenib in this patient population.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Duration of Progression Free Survival (PFS) for the experimental arm vs. the control arm [ Time Frame: Up to 27 months after the first subject is randomized. Defined as time from randomization to the earlier of progressive disease (PD) per RECIST 1.1 as determined by the Blinded Independent Radiology Committee (BIRC) or death from any cause. ]
    Duration of PFS per Response Evaluable Criteria in Solid Tumors version 1.1 (RECIST 1.1)

  2. Duration of Overall Survival (OS) for the experimental arm vs. the control arm [ Time Frame: Up to 36 months after the first subject is randomized. Defined as time from randomization to date of death from any cause. ]

Secondary Outcome Measures :
  1. Duration of Progression Free Survival (PFS) for the single-agent arm vs. the control arm [ Time Frame: Up to 20 months after the first subject is randomized. ]
    Duration of PFS per RECIST 1.1 by BIRC
