Brief Summary

Major Objectives To evaluate the efficacy of HAIC combined with Iparomlimab and Tuvonralimab injection (QL1706, an Anti-PD-1/CTLA-4 Combined Antibody) plus bevacizumab as a conversion therapy in patients with potentially resectable HCC, assessed by the conversion resection rate.

Detailed Description

This single-center, single-arm, phase II clinical study aims to evaluate the efficacy and safety of HAIC combined with Iparomlimab and Tuvonralimab injection (QL1706, an Anti-PD-1/CTLA-4 Combined Antibody) plus bevacizumab in patients with potentially resectable HCC. The study consists of four periods: screening, treatment, safety follow-up, and survival follow-up.Efficacy evaluation and safety monitoring should be performed throughout the study.

a. Deemed unsuitable for primary surgical resection at the current stage by the Multidisciplinary Team (MDT) assessment at the research center; b. At least one untreated measurable lesion according to RECIST v1.1 criteria. (Note: Subjects who received prior local therapy for non-target lesions are eligible. Local therapy must have been completed at least 4 weeks prior to baseline scans.); c. Largest tumor diameter ≥5 cm AND ≤3 tumor lesions; d. Absence of Vp3-Vp4 stage portal vein tumor thrombus (PVTT) as per the Japanese PVTT classification system; e. Oligometastasis is permitted;

7. Subjects with HBV or HCV infection must meet the following criteria:

1) HBV-infected subjects (HBsAg positive or HBV-DNA positive): Must have received guideline-recommended antiviral therapy for at least 3 days prior to the first study treatment, demonstrating a decreasing trend in HBV-DNA levels. Must continue to receive standard antiviral therapy throughout the study period; 2) HCV-infected subjects (HCVAb positive or HCV RNA positive): Must be in a stable condition per investigator assessment. If receiving antiviral therapy, must continue treatment throughout the study period; 3) Co-infection with HBV and HCV is not allowed.
