Inclusion criteria: 1. Can understand and voluntarily sign written informed consent. 2. Men or women aged 18-75 years (including the threshold). 3. Locally advanced or metastatic pancreatic ductal adenocarcinoma that is not suitable for surgical resection, confirmed by histopathological/cytological examination of the primary and/or metastatic sites. 4. The pathological biopsy of the primary site indicated at least one specific antigen; Blood target detection indicates the presence of at least one target. 5. No previous systematic treatment for unresectable metastatic pancreatic cancer. The use of fluorouracil or gemcitabine as radiotherapy sensitizers in adjuvant therapy is permitted, provided that the time from last administration to admission is greater than 6 months and that the toxic effects of prior treatment have returned to baseline or = grade 1 (except for alopecia and vitiligo; Stable or = grade 2 neuropathy induced by previous antitumor therapy). 6. Have at least one measurable lesion (non-nodular lesion with maximum diameter =10mm, or nodular lesion with short diameter =15mm) according to the solid tumor response evaluation criteria (RECIST 1.1). 7. Expected survival =6 months. 8. ECOG Fitness score 0-1. 9. No serious hematology, liver and kidney function abnormalities, consistent with the following laboratory test results: 1) Hematology: neutrophils =1.5×l09/L, platelets =75×109/L, hemoglobin =90g/L. 2) Liver function: alanine aminotransferase (ALT) and aspartate aminotransferase (AST), without liver metastasis ALT and AST= the upper limit of normal ×3, with liver tumor or liver metastasis ALT and AST= the upper limit of normal ×5; Alkaline phosphatase (ALP) patients with no liver metastasis = the upper limit of normal ×2.5, those with liver metastasis = the upper limit of normal ×5; Total bilirubin (TBIL) = upper limit of normal ×1.5. 3) Renal function: creatinine (Cr)< 1.5 × upper limit of normal value; Creatinine clearance = 60mL/min as calculated by Cockcroft-Gault formula. 4) Coagulation function: International standardized ratio (INR) =1.5 or prothrombin time (PT) =1.5 × ULN or activated partial prothrombin time (APTT) =1.5 × ULN. 5) Urine routine detection of urinary protein concentration =1+, no edema or serum albumin level below the lower limit of normal (LLN). 10. Female subjects must meet the following criteria: 1) Surgical sterilization or postmenopausal =2 years, or women of reproductive age (including postmenopausal < 2 years) a negative pregnancy test and a willingness to use effective birth control (such as condoms or Iuds) during the study period. Contraceptives containing progesterone are not allowed. 2) Agree not to breastfeed during the study period and for at least 28 days after the last study dosing. 11. Male subjects must meet the following criteria: If sterilization is not performed and sexual activity is likely to result in pregnancy, consent to use effective contraception (such as condoms) during the study period and for at least 28 days after the last study dosing. 12. The investigator determines that the subjects are willing and able to follow the protocol requirements for the study.
Exclusion criteria
Exclusion criteria: 1.
