Brief summary: Intrahepatic cholangiocarcinoma (ICC) is a malignant tumor of biliary epithelial cells that originates from the branches of the intrahepatic bile duct at the second level and above. Its incidence accounts for about 15%-20% of primary liver malignancies, showing a gradually increasing trend. Surgical resection is currently the main method for the treatment of ICC. However, most (60% -70%) patients are diagnosed at the advanced stage. Gemcitabine plus cisplatin is the standard first-line incurable resection recommended in international and domestic guidelines. There is not a standard second-line treatment that has progressed after standard first-line chemotherapy.

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 drug-eluting beads transarterial chemoembolization combined with apatinib and carrelizumab injection in the treatment of ICC that has progressed after standard first-line chemotherapy.

Patients who were aged 18 to 80 years with a histological or cytological diagnosis of ICC，locally advanced or multiple liver metastases, including progression after gemcitabine chemotherapy, will be enrolled in this trial.

Detailed description: This study is a single arm, single center, open label study. It is estimated that 20 patients with intrahepatic cholangiocarcinoma which progressed after treatment with standard first-line chemotherapy in patients will be enrolled. The trial period of subjects includes screening period, treatment period and follow-up period.

The drug treatment was 200 mg of PD-1 monoclonal antibody, intravenous infusion on the first day, every 21 days as a treatment cycle; mesylate apatinib, 250 mg, oral once a day, continuous oral; DEB-TACE, the CalliSpheres + gemcitabine (800mg) and oxaliplatin were injected into the hepatic artery by routine procedure, repeated every 4-6 weeks, and administered for according to the physician in charge, DEB-TACE treatment cycles. Treatment continues until the disease progresses, intolerable toxicity occurs, new anti-tumor treatment is started, informed consent is withdrawn, follow-up is lost, death occurs or treatment termination is required。 Screening will be performed between days - 21 and - 4. Informed consent was signed up to 4 weeks prior to the first day of cycle 1 before any screening procedure or evaluation was performed and the trial was fully explained to each subject.

Baseline evaluation results must be collected prior to the first trial drug administration (day 1 of cycle 1). Baseline assessments may be performed between days - 3 and - 1 or on day 1 of cycle 1. If performed within 3 days before the first day of cycle 1, the screening results can be used as baseline results.

The tumor imaging was evaluated every 4-6 weeks since the first administration, and every 12 weeks (± 7 days) after 24 weeks. If there are clinical indications for disease progression, tumor evaluation is more frequent. In the event of disease progression, unacceptable toxicity, the subject's request to discontinue the trial or the subject's withdrawal of consent, the subject will discontinue the trial treatment.

When the trial treatment is stopped, the treatment visit shall be stopped within 7 days after the treatment is stopped in order to stop the treatment examination.

After the end of the treatment period (up to 2 years), subjects who can benefit from the study drug will continue to study the treatment of the drug until disease progression, intolerable adverse reactions, withdrawal of intensive care facility (ICF), other anti-tumor treatment, loss of follow-up, death or termination of the study.

After the occurrence of a clinical event, if it is judged by the investigators that it should be attributed to the progress of the disease and it is unlikely to recover even if the patient continues to receive treatment, it can be evaluated as clinical deterioration. It is up to the investigator to discuss and decide whether to continue or stop the treatment for the subject and record in the study file.

At the end of the study, subjects who are still under study treatment can continue to receive treatment through another extended study or other forms at the discretion of the investigator if they are stable or relieved in the efficacy evaluation and can tolerate the adverse reactions.
