Clinical Trial Summary

This study intends to evaluate the efficacy and safety of cryoablation combined with Cardonilizumab and Bevacizumab in hepatocellular carcinoma with pulmonary metastases.

Description:

For advanced hepatocellular carcinoma (HCC), the lung is the most common metastatic organ, accounting for 30-50% of extrahepatic diseases. The standard therapy for advanced HCC with lung metastases according to the Barcelona Clinic Liver Cancer (BCLC) criteria is system therapy.

However, studies have proven that palliative ablation could improve the tumor controlling effect and the outcomes.

Cryoablation is a treatment method that involves freezing tumors at extremely low temperatures to destroy and eliminate them. This therapeutic approach can result in the death of tumor cells through necrosis and also stimulate immune targeting of tumor cells. These immune responses occur as a result of tumor cell death caused by the ablation procedure. In comparison to conventional cancer therapies, cryoablation has minimal adverse reactions and has the potential to promote a more extensive and effective release of self-generated antigens into the bloodstream.

Targeting vascular endothelial growth factor (VEGF) could reduce VEGF-mediated immunosuppression within the tumor. The IMbrave150 study of atezolizumab and bevacizumab versus sorafenib demonstrated response rates of 29.8% vs 12%, respectively, and median overall survival of 19.8 months in the combination arm versus 13.4 months in the sorafenib (P <0.001). Bevacizumab could enhance anti-PD-1 and anti-programmed death ligand 1 (PD-L1) efficacy by reversing VEGF-mediated immunosuppression and promoting T-cell infiltration in tumors (2).

Cadonilimab is a first-in-class bispecific, humanized IgG1 antibody targeting PD-1 and CTLA-4, which has the potential to boost immune surveillance in tumors. Preclinical studies have shown that its tetravalent design enhances its high binding activity in the tumor microenvironment. With no Fc binding, Cadonilimab could eliminate a series of functions mediated by the Fc receptor, which contribute to a poor safety profile in clinical settings.
