About this trial
The goal of this single-arm, Phase II interventional clinical trial is to test the safety and effectiveness of a combination treatment using the Cadonilimab with Gemcitabine and Cisplatin in patients with unresectable, locally advanced or metastatic biliary tract malignancies. The main questions it aims to answer are:
* Is this combined treatment protocol safe for these patients? * Is this combined treatment protocol effective in treating these patients?
Participants will be given a combination treatment of Cadonilimab, Gemcitabine, and Cisplatin. Researchers will monitor their health conditions to assess the safety and effectiveness of this treatment protocol.
