Brief Summary:
The recent global IMbrave150 study evaluated the combination of atezolizumab and bevacizumab versus sorafenib in 501 patients with advanced or metastatic Hepatocellular Carcinoma (HCC). The median overall survival (OS) was notably better in the atezolizumab/bevacizumab group. However, for HCC patients with intrahepatic macrovascular invasion (MVI), the prognosis remains poor, indicating a significant unmet need in this group.
External Beam Radiotherapy (EBRT) has shown promising results in treating HCC with MVI, especially when used in combination with trans-arterial chemoembolization (TACE). It has been reported that radiotherapy may make tumor cells more susceptible to immune-mediated therapy, potentially enhancing the effects of atezolizumab and bevacizumab.
Thus, this study aims to investigate the efficacy and safety of atezolizumab/bevacizumab alone versus atezolizumab/bevacizumab in combination with EBRT in HCC patients with macrovascular invasion.
Detailed Description:
A total of 138 subjects are randomly assigned to one of two treatment groups (69 patients in the atezolizumab+bevacizumab group and 69 patients in the Atezolizumab plus Bevacizumab combined EBRT group).
* Radiotherapy combination:
* Atezolizumab will be administered by IV, 1200 mg on day 1 of each 21day cycle.
* Bevacizumab will be administered by IV, 15 mg/kg on day 1 of each 21day cycle.
* The external beam radiotherapy will commence after day 2 of the first cycle of Atezolizumab+Bevacizumab, and will be delivered in accordance with institutional protocol.
* Atezolizumab+Bevacizumab:
* Atezolizumab will be administered by IV, 1200 mg on day 1 of each 21day cycle.
* Bevacizumab will be administered by IV, 15 mg/kg on day 1 of each 21day cycle.
