Clinical Trial Summary

This study is a single-center, single-arm, open-label clinical study. All patients with advanced and unresectable biliary tract tumors will be treated with the combination of tisleizumab, lenvatinib and XELOX regimen (oxaliplatin plus capecitabine) until disease progression , unacceptable toxicity, death or the patient meets any other discontinuation criteria described in the protocol, whichever occurs first. Subjects can receive up to 8 cycles of the XELOX regimen. For subjects who are intolerant to XELOX regimen or have stable disease or objective response after complete 8 cycles of XELOX regimen, treatment with tisleizumab and lenvatinib will be continued until tumor progression or for a maximum of 2 years. Patients will be closely monitored for safety and tolerability throughout the study.
