A Single-center, Single-arm, Open-label, Dose-escalation Clinical Study to Evaluate the Safety and Anti-tumor Efficacy of Intratumoral NKG2D CAR-NK Cell Injection Guided by EUS in the Treatment of Locally Advanced Pancreatic Cancer.
This is a single-center, single-arm, open-label, dose-escalation clinical study to evaluate the safety and anti-tumor efficacy of intratumoral NKG2D CAR-NK cell injection guided by endoscopic ultrasound in the treatment of locally advanced pancreatic cancer.
• 18\
⁃ 75 years old (including boundary value), both male and female.
• Histologically or cytologically confirmed pancreatic ductal adenocarcinoma or IPMN carcinogenesis.
• Recurrent or unresectable locally advanced pancreatic cancer. Patients with technically resectable tumors but are considered as unable to undergo surgical treatment due to medical comorbidities or the patient\'s refusal of surgery are also eligible for enrollment.
• ECOG PS score of 0-1.
• At least 3 months of life expectancy at screening, as judged by the investigator.
• Subject has adequate organ and bone marrow function. Laboratory screening results should be within the stable range described below, and there should be no ongoing supportive care (\"jaundice relieve\" therapy such as PTCD, ENBD, or bile duct stenting is allowed when pancreatic cancer invades the common bile duct). a) Blood biochemistry: serum creatinine ≤ 1.5×ULN, serum total bilirubin ≤ 2.0×ULN, and serum liver aminotransferase ≤ 3 ×ULN b) Blood tests: neutrophil count ≥ 1.5×109/L, platelet count ≥ 60×109/L, hemoglobin ≥ 8.0g/dL, lymphocyte count ≥ 0.4×109/L;
• Childbearing status: not pregnant and, if of childbearing potential, willing to use effective contraception from the time of signing the informed consent form until 6 months after the last cell infusion (women of childbearing potential include premenopausal women and women within 2 years of postmenopausal time).
• Subjects must sign a written informed consent form.
• Subjects must be voluntary and able to comply with the scheduled treatment regimen, laboratory tests, follow-up, and other study requirements.
