QL1706 in Combination With Bevacizumab and RALOX HAIC for Hepatocellular Carcinoma With Vp3/4 PVTT

The goal of this prospective, single-arm, multi-center Phase II clinical trial is to evaluate the clinical efficacy and safety of QL1706 combined with bevacizumab and RALOX hepatic artery infusion chemotherapy in treating liver cancer patients with VP3/4 portal vein tumor thrombus. It will also explore molecular biomarkers that predict the efficacy of this combined therapy. The main questions it aims to answer are: What is the progression-free survival (PFS) of patients treated with this regimen? What are the objective response rate (ORR), disease control rate (DCR), and overall survival (OS) of these patients? What is the safety and tolerability profile of this combined treatment? Which molecular biomarkers can predict the efficacy of this therapy? Eligible subjects (who have signed informed consent) will receive RALOX hepatic artery infusion chemotherapy plus QL1706 (7.5mg, intravenous infusion every 3 weeks) and bevacizumab (15mg/kg, intravenous infusion every 3 weeks), with 3 weeks as one treatment cycle. Treatment will continue until a protocol-specified discontinuation event occurs. After treatment, subjects will undergo post-treatment safety follow-up and survival follow-up; those who discontinue treatment for reasons other than disease progression or death will also have tumor progression follow-up.
