Inclusion Criteria:

1. Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for releasing personal health information explained to, understood by, and signed by the subject or legally authorized representative.
2. Age ≥ 18 years at the time of consent.
3. Eastern Cooperative Oncology Group of 0-1 Performance Status)
4. Histological or cytological evidence/confirmation of pancreatic ductal adenocarcinoma.
5. Female subjects of childbearing potential must be willing to abstain from heterosexual activity or to use 2 forms of effective methods of contraception from the time of informed consent until 6 months after study treatment discontinuation. The two contraception methods can be comprised of two barrier methods, or a barrier method plus a hormonal method or an intrauterine device that meets \< 1% failure rate for protection from pregnancy in the product label.
6. Male subjects with female partners must have had a prior vasectomy or agree to use an adequate method of contraception (i.e., double barrier method: condom plus spermicidal agent) starting with the first dose of study therapy through 3 months after the cell infusion therapy.

Exclusion Criteria:

1. Subjects with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen.
2. Subject is not willing and able to comply with study procedures based on the judgment of the investigator.

主要终点：Number of participants with adverse event · Number of participants with adverse event (AE)s as a measure of safety and tolerability of intraventricular administration iC9-CAR.B7-H3 T cells in subjects with progressive recurrent or refractory pancreatic cancer. AEs will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Dose Limiting Toxicities (DLTs) are defined as at least possibly related to iC9-CAR.B7-H3 T cell product administration. · Up to 4 weeks；Cytokine Release Syndrome · Cytokine Release Syndrome (CRS) will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) CRS Consensus Grading. Grade 1 - Mild (Symptomatic Management): Fever ≥38\^ o C, No hypotension, No hypoxia, Grade 2 - Moderate (Moderate Intervention): Fever ≥38\^ o C, Hypotension not requiring vasopressors, Hypoxia requiring low-flow nasal cannula (≤6 L/minute) or blow-by, Grade 3 - Severe (Aggressive Intervention): Fever ≥ 38\^ o C, Hypotension requiring a vasopressor with or without vasopressin, Hypoxia requiring high-flow nasal cannula (\>6 L/minute), facemask, nonrebreather mask, or Venturi mask, Grade 4 - Life-threatening (Life-sustaining intervention): Fever ≥38\^oC, Hypotension requiring multiple vasopressors (excluding vasopressin), Hypoxia requiring positive pressure (e.g. Continuous positive airway pressure, BiPAP, intubation, mechanical ventilation), Grade 5 - Death: Death. · Up to 4 weeks；Neurotoxicity · Neurotoxicity will be graded according to the Central Nervous System (CNS) Toxicity criteria. Grade 0: Normal or no change from baseline exam at start of therapy, Grade 1: Mild lethargy and/or irritability or visual, motor, or sensory symptoms without change in neurological exam, Grade 2: Moderate lethargy, disorientation, or psychosis lasting \< 48 hours or mild increase in pre-existing neurological deficit, Grade 3: \>48hours of severe lethargy, but responsive to verbal stimuli or disorientation or psychosis lasting \>48 hours, Grade 4: Coma, unresponsive to verbal stimuli, increasing neurological deficit above grade 3, evidence of herniation, development of uncontrolled seizures, intracerebral hemorrhage. · Up to 4 weeks
次要终点：Definition of Dose Limiting Toxicity；Progression Free Survival (PFS)；Overall Survival (OS)；The disease control rate (DCR)；B7-H3 expression；The proportion of subjects who were able to receive CAR-T cell infusion；Objective response rate (ORR)- bridging therapy；Objective response rate- no bridging therapy

• CAR-T Cell Therapy · EXPERIMENTAL · Single Arm Subjects with Refractory Pancreatic Ductal Adenocarcinoma (PDAC) cancer will receive iC9.CAR.B7-H3 T cells manufactured from their collected blood sample.

The purpose of this gene therapy research study is to test the safety and tolerability of using a new treatment called autologous T lymphocyte chimeric antigen receptor cells against the B7-H3 antigen (iC9.CAR.B7-H3 T cells) in patients with pancreatic ductal adenocarcinoma that came back after receiving standard therapy for this cancer. The iC9.CAR.B7-H3 treatment is experimental and has not been approved by the Food and Drug Administration.
