Volunteers: No Healthy Volunteers

Inclusion criteria

1. The subject must sign the written informed consent form, and can comply with the visits and related procedures specified in the protocol.
2. Aged ≥18 years.
3. Patients with unresectable or relapsed or metastatic advanced Biliary tract cancer,and diagnosed by histology/cytology (except carcinoma of ampulla).
4. Had progressed after receiving at least first-line systemic treatment (if a patient has progressed within 6 months after receiving systemic treatment during adjuvant chemotherapy or concurrent radiochemotherapy, she will be deemed to have received first-line treatment).
5. Patients who have never received any anti-PD-1, anti-PD-L1/L2 antibody, anti-CTLA-4 antibody, or other immunotherapy.
6. The subject must have at least one measurable lesion as the target lesion (according to RECIST V1.1). A measurable lesion in the radiation field from previous radiotherapy or local treatment, can also be chosen as the target lesion if confirmed progression.

Exclusion criteria

1. Diagnosis of other malignant tumors within 5 years before the first administration, excluding radically cured skin basal cell carcinoma, skin squamous cell carcinoma, radically resected carcinoma in situ and/or thyroid papillary carcinoma.
2. Patients who have previously received organ or bone marrow transplantation.
3. Patients with acute or chronic active hepatitis B or C infection, hepatitis B virus (HBV) DNA> 2000 IU/ml or 104 copies/ml; hepatitis C virus (HCV) antibody positive and HCV-RNA >103 copies/ml;. Patients with acute or chronic active hepatitis B or C infection who have received nucleotide antiviral therapy and are below the above standards can be selected.
4. Uncontrollable hypertension, systolic blood pressure ≥150 mmHg or diastolic blood pressure ≥100 mmHg after best medical treatment, history of hypertensive crisis or hypertensive encephalopathy.
5. Pleural effusion, ascites, and pericardial effusion with clinical symptoms or requiring drainage , patients who only shows with a few pleural effusion, ascites, and pericardial effusion by imaging and with no clinical symptoms can be selected.
