3. Pathologically or cytologically confirmed biliary tract cancer

4. Patients who are advanced and/or unresectable after imaging and multidisciplinary consultation

5. Patients must have at least one measurable lesion as defined by RECIST 1.1

6. Survival expectation of 12 weeks or longer after beginning of study treatment

7. The major organs meeting the following criteria:

   Adequate bone marrow function,defined as: Hemoglobin (HGB) ≥80g/L;Neutrophil absolute count (ANC) ≥1.0×10^9/L;Platelet (PLT) ≥60×10^9/L

   Adequate liver function, defined as: aspartate aminotransferase (AST), and alanine aminotransferase (ALT) ≤ 2.5× upper limit of normal (ULN) ( ≤ 5.0 × ULN for participants with the liver transplantion);Serum total bilirubin（STB） <1.5×ULN

8. Patients requiring biliary stent implantation must complete the procedure at least 14 days before enrollment

Exclusion Criteria

1. Allergy to Lenvatinib or PD-1 inhibitors
2. Patients who have had other malignancies within the past 2 years (except cured carcinoma in situ and basal cell carcinoma of the skin)
3. Patients who have previously received systemic therapy, except for permitted neoadjuvant/adjuvant therapy, neoadjuvant/adjuvant therapy should be completed at least 4 months before diagnosis of advanced and/or unresectable disease
4. Patients with ampullary carcinoma are excluded (patients with mixed HCC/ BTC may be considered)
5. Active autoimmune disease requiring systemic treatment (i.e. corticosteroids or immunosuppressive drugs) within the past 2 years.Alternative therapies (e.g., thyroxine, insulin, or physical corticosteroid replacement for adrenal or pituitary insufficiency) are not considered systemic and permitted
6. Major surgery prior to initiation of the study intervention and insufficient recovery from surgery and/or surgical complications
7. Radiation therapy was received within 2 weeks prior to initiation of study therapy. Or the subject must have recovered from all radiation-related toxicity, not required corticosteroids, and have not experienced radiation pneumonia; Palliative radiotherapy for non-central nervous system (CNS) disease (≤2 weeks) allows a washout period of 1 week (if deemed safe by the investigator)

Arm && Interventions

Group	Intervention	Description
Lenvatinib+PD-1 inhibitors	Lenvatinib	Participants received lenvatinib capsules 8 mg , orally, once daily (QD) PD-1 inhibitors in this study include, but not limited to, Pembrolizumab, nivolumab, sintilimab, toripalimab, etc. The usage and dosage refer to label information or other clinical study
Lenvatinib+PD-1 inhibitors	PD-1 inhibitors	Participants received lenvatinib capsules 8 mg , orally, once daily (QD) PD-1 inhibitors in this study include, but not limited to, Pembrolizumab, nivolumab, sintilimab, toripalimab, etc. The usage and dosage refer to label information or other clinical study

Primary Outcome Measures

Name	Time	Method
ORR	12-months	ORR was assessed by the investigator based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. ORR was defined as the percentage of participants with best overall response (BOR) of complete response (CR) or partial response (PR). Confirmation of CR or PR was performed at least 28 days following the initial achievement of the response

Secondary Outcome Measures

Name	Time	Method
Disease Control Rate (DCR)	12-months	DCR was assessed by the investigator based on RECIST 1.1. DCR was defined as the percentage of participants whose BOR was CR, PR or SD
Overall Survival (OS)	24-months	OS was defined as the time from the date of first dose to the date of death from any cause. For the participants who were alive or unknown, OS was censored on the last date participant was known to be event-free or date of data-cut-off. OS was calculated using the Kaplan-Meier method.
Overall Survival (OS) Rate at 9 months	9-months	OS was defined as the time from the date of first dose to the date of death from any cause. For the participants who were alive or unknown, OS was censored on the last date participant was known to be event-free or date of data-cut-off.
Progression-free Survival (PFS)	12-months	PFS was assessed by the investigator based on RECIST 1.1. PFS was defined as the time from the date of first dose to the date of last documentation of disease progression or date of death from any cause, whichever occurred first. For participants who did not have an event, PFS were censored. PFS was calculated using Kaplan-Meier method
Overall Survival (OS) Rate at 12 months	12-months	OS was defined as the time from the date of first dose to the date of death from any cause. For the participants who were alive or unknown, OS was censored on the last date participant was known to be event-free or date of data-cut-off.
