About

TOPAZ-1 phase III trail demonstrated that the addition of immune checkpoint inhibitor anti-PD-L1 antibody improved progression-free survival (PFS) and overall survival (OS) compared to Gem/Cis alone. 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. The goal of this clinical trial is to evaluated the efficacy and safety of cadonilimab combined with gemcitabine and cisplatin as first Line therapy in patients with advanced intrahepatic cholangiocarcinoma. Eligible participants will receive cadonilimab (up to 12 months) plus gemcitabine and cisplatin (for maximum of 6-8 cycles) until radiologic disease progression, unacceptable toxicity, or withdrawal from the study, whichever occurred first. The primary endpoint is objective response rate.
