Criteria

Inclusion Criteria: Subjects must meet all of the following criteria

• Subjects volunteer to participate in the study and agree to sign the informed consent with good compliance and follow-up.

• Subjects are 18 years old or older when signing the informed consent and gender is not limited.

• Subjects were diagnosed with advanced hepatobiliary malignant tumors (clinical stage IV) by imaging and histological examination, including hepatocellular carcinoma, cholangiocarcinoma, ampullary carcinoma, gallbladder carcinoma and mixed carcinoma.

• The disease is not suitable for radical surgery and/or topical treatment, or disease progression occurs after surgery and/or local treatment.

• At least one measurable lesion (according to RECIST version 1.1): the measurable lesion has a long diameter ≥ 10 mm or lymphadenopathy has a short diameter ≥ 15 mm in spiral CT scan.

• Patients fail after at least one systemic failure, including surgery, intervention, radiotherapy, chemotherapy and targeted therapy and require palliative treatment.

Definition of treatment failure: Disease progression during treatment or relapse after treatment, such as after at least once radical or palliative resection surgery, revenue recurrence or progression after intervention therapy or radiotherapy. Intervention therapy or oxaliplatin treatment must be more than 1 cycle, and molecular targeted therapy must more than ≥14 days.

Definition of intolerance: Grade ≥IV hematologic toxicity, or grade ≥III non- hematologic toxicity, or grade ≥ II damage of heart, liver and kidney during treatment.

• The ECOG score is 0-1 within 1 week before enrollment.

• Liver function assessment: Child-Pugh Grade A or mild Grade B (score ≤ 7), BCLC stage B-C.

• More than 2 weeks from first-line system treatment failure to sign informed consent for this study, and adverse events returned to normal (NCI-CTCAE ≤ I).

• Estimated survival time ≥ 6 months.

• HBV DNA <2000 IU/ml (10^4 copies/ml).

• Hematology and organ function are sufficient based on the following laboratory results within 14 days prior to the treatment of this study:

Whole blood cell examination (no blood transfusion within 14 days, no G-CSF use and no drugs use): Hb≥100g/L, ANC≥1.5×10*9/L, PLT≥75×10*9/L.

Biochemical examination (no ALB infused within 14 days): ALB≥35g/L, ALT and AST<3×ULN, TBIL≤2×ULN, creatinine≤1.5×ULN, PT≤ULN+4S, INR≤2.2 (note: only one of albumin and bilirubin is permitted Child-Pugh score 2).

• There are no active autoimmune diseases that require systemic therapy in the past 2 years (note: active state means requiring disease modulators, corticosteroids or immunosuppressive drugs use). Alternative therapies, such as thyroxine, insulin or a physiological corticosteroid replacement therapy are not considered as systemic therapy.

• Women with fertility agree to abstinence during the treatment period and at least 6 months after the last dose (avoiding heterosexual intercourse) or using a contraceptive method with an annual contraceptive failure rate <1%.

If a female patient has menstruation and not reached the postmenopausal state (continuously no menstruation ≥ 12 months and no other causes), and has not undergone sterilization by removing the ovaries and/or uterus), then the patient has fertility.

Contraceptive methods with a contraceptive failure rate <1% include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices and copper intrauterine devices.

The reliability of sexual desire should be evaluated relative to the duration of the clinical trial and lifestyle of patient. Periodic abstinence (eg. calendar days, ovulation, symptomatic body temperature or post-ovulation methods) and in vitro ejaculation are unacceptable methods of contraception.

• Male patients agree to abstinence (no heterosexual intercourse) or use of contraceptive measures and no sperm donation, as defined below:

When a female partner has fertility, male patients must abstinence from sex during treatment and at least 6 months after the last dose of treatment, or use condoms and other contraceptive methods with contraceptive failure rate <1%. At the same time, male patients must also agree not to donate sperm.

When a female partner is pregnant, the male patient must abstinence or using a condom during the treatment period and at least 6 months after the last dose of treatment to prevent the fetus from being affected by the study.

The reliability of sexual desire should be evaluated relative to the duration of the clinical trial and lifestyle of patient. Periodic abstinence (eg. calendar days, ovulation, symptomatic body temperature or post-ovulation methods) and in vitro ejaculation are unacceptable methods of contraception.

• Tumor tissue must be available for biomarker analysis prior to the first dose of treatment, If not available, participants can consult the investigator for enrollment agreement. (Note: If an unstained section is submitted, the new section should be submitted to the laboratory within 14 days.)

Exclusion Criteria: Subjects with one or more than one of the following criteria should be excluded
