- Conditions
- HCC
- Interventions
- Drug: lparomlimab and Tuvonralimab Injection in Combination with HAIC and bevacizumab
- Registration Number
- NCT07119931
- 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.
