A Study of Sintilimab Combined With Apatinib and Capecitabine in Advanced Hepatocellular Carcinoma

This study aims to evaluate the efficacy and safety of Sintilimab (an Anti-PD-1 Inhibitor) combined with apatinib and capecitabine as first-line therapy in patients with advanced hepatocellular carcinoma.
