Brief summary: This is a prospective, single arm, single center, phase II study of NALIRIFOX as conversion therapy in patients with locally advanced pancreatic cancer.

Detailed description: Subjects will be treated with the NALIRIFOX regimen every 2 weeks in 4-weeks cycles Imaging of tumor lesions will be performed after the subject has completed the first 2 cycles of treatment, and if the subject has not progressed, the subject will continue treatment until surgical resection, disease progression (RECIST 1.1) or intolerable toxicity, start of new anticancer drug therapy, withdrawal from the study, death, or loss to follow-up. All treated subjects will be evaluated for response while on this treatment every 8 weeks (±7) days after until surgical resection, disease progression (RECIST 1.1), intolerable toxicity, start of new anticancer drug therapy, withdrawal from the study, death, or loss to follow-up.. After 24 weeks of treatment, capecitabine or S-1 is the maintenance regimen. Radiographic response will be evaluated every 12 weeks (± 7 days) during the maintenance phase.

3. ECOG score 0-1;
4. The subject had histopathologically or cytologically confirmed type of pancreatic ductal adenocarcinoma
5. Local progression according to the 2022 CSCO guidelines;
6. Initial subjects with locally advanced pancreatic cancer who have not undergone resection of pancreatic tumor (except open exploration or internal drainage surgery), chemotherapy, targeted, or immunotherapy.
7. At least one measurable pancreatic lesion per RECIST 1.1 criteria;
8. Expected survival time ≥ 3 months.
9. Heart, lung, liver, kidney and other major organ functions are basically normal.
10. Hematology tests should meet the following criteria (no blood transfusion, no use of blood products, granulocyte colony-stimulating factor, or other hematopoietic growth factors within 7 days prior to hematology):

    1. White blood cell count ≥ 3.0 × 109/L and neutrophil count ≥ 1.5 × 109/L.
    2. Platelet count ≥ 100 × 109/L.
    3. Hemoglobin ≥ 90 g/L.
    4. If component blood transfusions (red blood cells, platelets, etc.) are received at screening, reexamination of hematology must be performed at 1-week intervals before further screening can be considered.
11. Blood chemistry tests should meet the following criteria:

    1. Plasma total bilirubin ≤ 1.5 × upper limit of normal.
    2. ALT, AST, or ALP ≤ 2.5 × upper limit of normal;
    3. Creatinine clearance ≥30 mL/min calculated by the Cockcroft-Gault formula (Cockcroft-Gault formula: male Ccr = \[(140-age) × body weight (kg)\]/\[0.818 × Scr (μmol/L)\] or Ccr = (140-age) × body weight (kg)/72 × Scr (mg/dl), and female Ccr calculated as male × 0.85);
12. The subject had no symptoms of cardiac insufficiency (NYHA functional class ≤ II) at baseline and had no obvious abnormalities or abnormalities in electrocardiograms that were not clinically significant.
13. Good compliance, voluntary compliance with this clinical trial protocol and follow-up by the investigator during the study.
14. Subjects of childbearing potential voluntarily take highly effective contraceptive measures in the trial.
15. Females must be non-lactating.

Exclusion Criteria:

1. Known allergy or intolerance to the ingredients or excipients of this investigational product.
2. Any metastatic lesions.
3. Patients with unresolved acute or chronic infection
4. Other malignancies within 5 years (except cured basal cell carcinoma of the skin and carcinoma in situ of the cervix);
5. Active hepatitis.
6. Patients with portal hypertension or cavernous transformation of the portal vein; patients with gastrointestinal bleeding caused by tumor involving the digestive tract; patients with intra-abdominal fistula or abscess due to tumor involvement of digestive tract; the tumor encircles the celiac trunk or SMA and causes significant vascular wall involvement (worm-like changes);
7. Presence of third space effusion that cannot be controlled by drainage or other means (e.g., moderate-large pleural effusion, moderate-large pericardial effusion, ascites); a small amount of pleural effusion or ascites that is not clinically symptomatic and does not require clinical intervention should be strictly controlled before enrollment.
8. Mental illness or mental disorder, poor compliance, unable to cooperate with treatment
9. Patients with severe organic diseases or major organ failure, such as decompensated heart and lung failure, which lead to intolerance to chemotherapy.

17. Subjects with active hepatitis B or hepatitis C (HBV DNA ≥ 1 × 104 copies or ≥ 2000 IU/mL regardless of drug control; hepatitis C infection, HCV RNA ≥ 15 IU/mL); or HIV antibody positive (testing is not required if there is no clinical evidence of possible HIV infection); or syphilis antibody (TPPA) positive.
18. Breast feeding, known pregnancy, positive serum pregnancy test or unwillingness to use a reliable method of birth control, during therapy and for 6 months following the last dose of nal-IRI. Females of Childbearing Potential must either agree to use and be able to take effective contraceptive birth control measures (Pearl Index \< 1) or agree to use effective contraception during treatment and for at least 7 months after last application of program treatment. Males with female partners of reproductive potential should use condoms during treatment and for 4 months after the last dose. A female subject is considered to be of childbearing potential unless she is age ≥ 50 years and naturally amenorrhoeic for ≥ 2 years, or unless she is surgically sterile. Males must agree not to father a child (including not donating sperm) during the course of the trial and for at least 6 months after last administration of study drugs.
