Transarterial Infusion of PD-1 Antibody Plus TACE-HAIC for Unresectable HCC: a Single-arm, Phase 2 Clinical Trial

Hepatocellular carcinoma (HCC) is a common disease in East Asia. Less than 20% of newly diagnosed patients can undergo radical resection. For those with unresectable BCLC C stage, transarterial chemotherapy and targeted therapy are recommend to prolong survival. Recently, FOLFOX (Oxaliplatin and 5-fluorouracil) based hepatic artery infusion chemotherapy (HAIC) exhibited high response rate for unresectable HCC. Transartery infusion of agents provide promising outcome when compared systemic infusion. Furthermore, our pilot study showed TACE combined HAIC (TACE-HAIC) had better tumor response, with low progression disease rate. Whether TACE-HAIC plus hepatic artery infusion PD-1 antibody would improve survival for unresectalbe BCLC C stage patients is still unknown. A single arm, phase 2 clinical trial is aimed to answer this question.
