Multicenter Phase 2 Trial of Second-Line Regorafenib in Patients with Unresectable Hepatocellular Carcinoma after Progression on Atezolizumab plus Bevacizumab.

ABSTRACT:

Introduction

Atezolizumab-bevacizumab (Atezo-Bev) has become the standard first-line treatment for patients with unresectable hepatocellular carcinoma (uHCC). However, data on subsequent treatment after Atezo-Bev failure are lacking. We aimed to investigate the efficacy and safety of regorafenib for uHCC progression after first-line Atezo-Bev.

Methods

This investigator-initiated, single-arm, phase 2 trial involved two academic centers in Korea. Eligibility criteria included a diagnosis of HCC, prior treatment with at least 2 cycles of Atezo-Bev, and Child-Pugh A liver function. Eligible patients received regorafenib 160 mg once daily for 3 weeks of every 4-week cycle (i.e., 3 weeks on, 1 week off) until progressive disease or intolerable toxicity.
