Brief summary: Biliary tract cancer (BTC) is a series of rare malignancies with poor overall prognosis. Radical surgery the preferred treatment option, but most patients have lost the opportunity of surgery at the time of diagnosis. At present, there are limited systematical treatment options for biliary tract cancer, with poor efficacy and short duration of responses. In the past few years, immune checkpoint inhibitors (ICIs) therapy has gradually been added to the advanced biliary comprehensive treatment. However, in view of the low incidence and high heterogeneity of BTC, more large number of clinical trials and practices need to be carried out, and the effective combination regimens and predictive biomarkers need to be explored. This study is a single-arm, open-label, prospective cohort study, combining Camrelizumab with apatinib and capecitabine as the first-line or second-line treatment for patients with advanced biliary tract cancer. The study aims to explore the efficacy and safety of the combination regimen, and try to find biomarkers that can guild treatment. In this study, 34 patients were enrolled by the Simon's two-stage design, with the objective response rate as the primary endpoint and the disease control rate, progression-free survival, overall survival and safety as secondary endpoints. It is expected that the three-drug combination regimen will have significant efficacy and manageable adverse reactions, and predictive biomarkers can be found.
