Details and patient eligibility


This study is designed to observe and evaluate the safety and the efficacy of the anti-programmed-death-1 antibody (anti-PD-1) Triprilumab in combination with chemotherapy of Gemcitabine PLUS Cisplatin in patients who were advanced intrahepatic cholangiocarcinoma with no chance for primary surgery.

Full description

Intrahepatic cholangiocarcinoma, also known as intrahepatic cholangiocarcinoma, is derived from intrahepatic bile duct epithelial cells, the second most common primary liver malignant tumor in china. but most (60% -70%) patients is diagnosed at the advanced stage . Gemcitabine plus cisplatin is the standard first-line advanced treatment recommended in international and domestic guidelines, but the treatment effect remains to be improved. The clinical benefits of immune therapies for HCC are emerging. Early clinical data already show the safety of immune checkpoint inhibition. This study is to analyze the safety and efficacy of immunotherapy Triprilumab Injection combined with Gemcitabine Injection plus Cisplatin Injection in patients with advanced intrahepatic cholangiocarcinoma. Patients who were aged 18 to 80 years with a histological or cytological diagnosis of intrahepatic cholangiocarcinoma´╝îlocally advanced or multiple liver metastases, including postoperative occurrence, will be enrolled in this trial.
