Spots Global Cancer Trial Database for A Study of the Efficacy and Safety of Chemotherapy Combined With Toripalimab in Advanced Biliary Tract Cancer

Study Description

Brief Summary: 1. Target population: patients with advanced biliary tract cancer (including gallbladder carcinoma, intrahepatic and extrahepatic cholangiocarcinoma) . 2. Primary objective: progression free survival (PFS)/ overall survival (OS) of first-line chemotherapy plus PD-1 antibody (Toripalimab) in patients with advanced biliary tract cancer. Secondary objectives: 1. objective response rate (ORR) of first-line chemotherapy plus PD-1 antibody (Toripalimab) 2. safety of first-line chemotherapy plus PD-1 antibody (Toripalimab) 3.Trial design: This is a monocenter, single arm, phase II study to evaluate the efficacy and safety of first-line chemotherapy plus PD-1 antibody (Toripalimab) in patients with advanced advanced biliary tract cancer. 4.Treatment plan: Patients will be given treatment as below once recruited: PD-1 antibody Toripalimab（240mg, iv, q3w），combined with GS regimen(gemcitabine 1000mg／m2 ，d1,d8 + S1 40-60mg bid\*14d，Q21d). The treatment will be continued until emerging of disease progression or intolerable adverse effects (The upper time limit for treatment is 2 years). 5.Number of subjects: 40 patients. Number of centers: 1 sites ( Fudan University Affiliated Zhongshan Hospital).

Detailed Description: Backgrounds: Toripalimab (JS-001) is a PD-1 antibody developed by Shanghai Jun Shi Biomedical technology Co. Ltd. Nowadays, eighteen clinical trials of this drug have been conducted in patients with different types of advanced malignant tumor. Until now, Toripalimab has exhibited favorable safety in recruited patients. Incidence rate of SAE is 14.7%. JS001-Ib-CRP-1.0 is a phase Ib/II basket trial, aiming at evaluating safety and efficacy of JS001 in treating advanced gastric adenocarcinoma, esophageal squamous cell carcinoma, nasopharyngeal carcinoma and head and neck squamous cell carcinoma.The interim analyses results of 161 patients show that the ORR is 22.4%. Now, the standard chemotherapies regimen for advanced biliary tract cancer include gemcitabine, platinum and fluorouracil; Considering the synergistic effect of chemotherapy and immune therapy, the investigators choose GS regimen (gemcitabine+S1) to combine Toripalimab. the investigators will shut down the study in advance, if unpredicted SAE or low efficacy occur. Patients with abnormal autoimmune status, unfavorable body function, factors impeding drug taking, absorption and metabolism will be excluded. Study participants with disease progression or severe/ intolerant toxicity during treatment will withdraw the study. Hyper-progressive disease is defined as 1) progression 2) more than doubled growth rate 3) tumor volume increase \>50% in 2 months after initialing the treatment.
