Brief summary: This phase II trial studies how well gemcitabine, cisplatin and durvalumab/Pembrolizumab and surufatinib work in treating participants with advanced Biliary Tract Cancer. The international multicenter phase III clinical study TOPAZ-1 has confirmed that durvalumab combined with gemcitabine and cisplatin can bring survival benefits to advanced BTC. Whether if adding surufatinib to a standard of care can bring addition benefit needs to be explored.


Eligibility criteria: Inclusion Criteria:

1. Patients with biliary tract cancer who are clearly diagnosed by pathology, are unable to undergo radical surgery or have local/distant metastasis (allowing surgical treatment after successful transformation).
2. Have at least 1 lesion that can be measured according to RECIST v1.1 (more than 1cm on CT or MRI).

9. Bone marrow reserve and liver and kidney function (as demonstrated by the following laboratory tests prior to initial treatment) :

   Neutrophil absolute value ≥ 1,000/mm3; Hemoglobin \> 8g/dL; Platelet count \> 80,000/mm3; Glutamic pyruvic transaminase/glutamic oxalacetic transaminase \< 3×ULN; Serum creatinine \< 3×ULN. Total bilirubin level \< 3×ULN.

13. The previous treatment for the tumor has ended for at least 4 weeks, and the adverse reactions of the previous treatment have basically recovered (according to the CTCAE5.0 standard ≤ Grade 1, except hair loss).
14. Voluntarily enrolled in the group and signed informed consent, followed the experimental treatment plan and visit plan, and could cooperate to observe adverse events and efficacy.

Exclusion Criteria:

1. Join another clinical study at the same time, unless it is during the follow-up period of an observational (non-interventional) or supportive care clinical study or interventional study.
2. Obstructive jaundice (bilirubin \> 1.5 ULN) with inadequate biliary drainage.
3. Absolute neutrophil count (ANC) \<1×109/L or platelet \<80×109/L or hemoglobin \< 8g/dL (based on the normal value of the clinical trial center)
4. Serum total bilirubin was 5 times higher than the upper limit of the normal reference range;
5. ALT, AST or ALP above 5 times the upper limit of the normal reference range;
6. Known active central nervous system metastatic and/or cancerous meningitis; Patients with previously treated BMS may participate provided they are stable (there is no evidence of imaging progression at least 4 weeks before the first dose of trial treatment, and any neurological symptoms have returned to baseline levels), there is no evidence of new or expanded BMS, and there is no evidence of new or expanded BMS.

9. Organ failure; Heart: Grade III and grade IV; Liver: reached Child-Pugh liver function grade B and C; Kidney: renal failure and uremia stage; Lungs: Symptoms of severe respiratory failure; Brain: A person with a disorder of consciousness.
10. History of heart disease:

1) Patients with pre-existing arrhythmias with prolonged PR, QTc and/or QRS; 2) Acute myocardial infarction or congestive heart failure within 6 months; 3) Patients with long QT syndrome; 4) Patients who have been treated with antiarrhythmic drugs (e.g. quinidine IA, amiodarone III, sotalol); 11. Patients who have undergone major surgery within 4 weeks prior to the start of study treatment, or who expect to undergo major surgery (other than surgery for diagnostic purposes) during the study period; 12.HIV antibody positive, or have other acquired, congenital immunodeficiency diseases, or have a history of organ transplantation; 13. Uncontrolled co-morbidity, including but not limited to persistent or active infections, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina, arrhythmia, interstitial lung disease, severe chronic gastrointestinal disease with diarrhea, or mental illness/social conditions, will limit compliance with study requirements. Substantially increases the risk of developing AEs or impairs a patient's ability to give written informed consent.

14. Patients with a history of Parkinson's disease or epilepsy, or who had a history of transient ischemic attacks, stroke, or traumatic brain injury with disturbance of consciousness in the 12 months prior to the study; 15. CTCAE2 grade infection that does not respond to treatment or CTCAE grade \> 2 active clinically serious infection.

16. Patients with active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection who require treatment.

17. Known or suspected prior allergy or hypersensitivity to any investigational drug or to any investigational drug excipient (duvaliumab, Sofantinib, Pabolizumab).

18. Chronic diseases requiring immunological agents or hormone therapy; 19. Women who are pregnant (positive pregnancy test before medication) or breastfeeding; 20. Participated in a non-anti-PD1 /L1 antibody based clinical trial within the past 30 days.

21. Patients with rare heritability should not participate in this clinical study.
