Brief Summary

In this phase 2 study, the investigators aim to evaluate the efficacy and safety of combined therapy using gemcitabine and cisplatin chemotherapy, Lenvatinib and Adebrelimab for patients with advanced and unresectable intrahepatic cholangiocarcinoma

Detailed Description

Most intrahepatic cholangiocarcinoma (ICC) patients are often accompanied by local or distant metastases and lose the opportunity for surgical resection. For patients with unresectable ICC who have been in stages IIIb and IV (AJCC/UICC, V2, 2018), the survival time is less than 4 months, and there is currently no standard treatment. TheGC chemotherapy (gemcitabine and cisplatin) has been used in the treatment of advanced intrahepatic cholangiocarcinoma, but the efficacy is still unsatisfactory. Lenvatinib is a small molecule multi-kinase inhibitor, the main targets including VEGFR1-3, fibroblast growth factor receptor 1-4, PDGFRα, RET(ret proto-oncogene ), KIT(KIT proto-oncogene, receptor tyrosine kinase), have anti-angiogenic effects, have been proven effective in hepatocellular carcinoma. In recent years, immunological checkpoint inhibitors (ICIs) have shown remarkable therapeutic effects in the treatment of various solid tumors. Combined with other therapies such as chemotherapy and targeted drugs is an important direction to improve the therapeutic effect of immunological checkpoint inhibitors. In this study, the investigators aim to evaluate the efficacy and safety of GC chemotherapy combined with Lenvatinib and immune checkpoint inhibitor PD-L1 antibody Adebrelimab for patients with advanced and unresectable intrahepatic cholangiocarcinoma.
