This is a phase 3 study. All subjects are patients with unresectable locally advanced or metastatic biliary tract cancer (BTC), Eastern Cooperative Oncology Group (ECOG) performance status 0-1. The purpose of this study is to evaluate the efficacy and safety of AK112 in combination with chemotherapy versus durvalumab in combination with chemotherapy in patients with unresectable locally advanced or metastatic BTC.

AK112 will be administered at a selected dose intravenously (IV) every three weeks (Q3W). Gemcitabine will be administered at 1000 mg/m2, D1, D8, Q3W, intravenously (IV) for 8 cycles. Cisplatin will be administered at 25 mg/m2, D1, D8, Q3W, intravenously (IV) for 8 cycles.
Durvalumab will be administered at 1500mg intravenously (IV) every three weeks (Q3W) for 8 cycles and followed by monotherapy every 4 weeks. Gemcitabine will be administered at 1000 mg/m2, D1, D8, Q3W, intravenously (IV) for 8 cycles. Cisplatin will be administered at 25 mg/m2, D1, D8, Q3W, intravenously (IV) for 8 cycles.

Overall Survival (OS)
OS is the time from randomization to death due to any cause.
Time frame: Up to approximately 2 years
Progression Free Survival (PFS)
PFS is defined as the time from randomization to the first documented disease progression (per RECIST v1.1 criteria) assessed by investigators or death due to any cause, whichever occurs first.
Time frame: Up to approximately 2 years
Objective Response Rate (ORR)
ORR is the proportion of subjects with complete response(CR) or partial response(PR) , assessed by investigators based on RECIST v1.1.
Time frame: Up to approximately 2 years
Duration of Response (DoR)
The DoR was defined as the time from the date of first documented OR (confirmed CR or confirmed PR) until date of documented progression (PD) based on investigator assessments by using RECIST version 1.1 or death in absence of disease progression.
Time frame: Up to approximately 2 years
Disease Control Rate (DCR)
DCR is the proportion of subjects with complete response(CR) , partial response (PR) or stable disease (SD) , assessed by investigators based on RECIST v1.1.
Time frame: Up to approximately 2 years
Time to response (TTR)
TTR is defined as the time to response based on RECIST v1.1.
Time frame: Up to approximately 2 years
Adverse Events (AEs)
An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.
