Study Details
Study Description
Brief Summary
To evaluate the efficacy and safety of cadonilimab combined with regorafenib in patients with HCC who progressed on systemic therapy.

| Phase 1/Phase 2 |
Detailed Description
Currently, second-line treatment options for advanced HCC (aHCC) patients including single TKI or anti-PD-(L)1 remains limited survival benefits and objective responses. To explore more effective and safer second-line or later therapies for aHCC is necessary. Cadonilimab is a first-in-class humanized IgG1 bispecific antibody that binds to PD-1 and CTLA-4 simultaneously. Dual checkpoint inhibition of the PD-1 and CTAL4 pathways with single cadonilimab has the potential to boost immune surveillance in HCC. Previously data indicated that cadonilimab possesses an encouraging anti-tumour activity and an improved safety profile compared to the co-administration of anti-PD-1 plus anti-CTLA-4 antibodies. Regorafenib is a TKI and approved for second-line treatment of uHCC globally. Here, we evaluated the safety of cadonilimab plus regorafenib as second-line or later therapy in patients with aHCC.
