Study Arms (1)

METR-NK cell（metabolic remodeling nature killer cells）

EXPERIMENTAL

Intraperitoneal allogeneic METR-NK cells infusion ： Dilute 200 mL of METR-NK cells in 1500 mL of 0.9% saline solution at 37°C. The minimum amount of METR-NK cells infused each time should be no less than 7.5×10\^7 cells per kilogram. Continuous infusion for 2 days constitutes one course, with 4 courses, with 13-day interval between each course

Drug: METR-NK cell(Metabolic Remodeling Nature Killer Cells)

Interventions

METR-NK cell(Metabolic Remodeling Nature Killer Cells) DRUG

The minimum amount of METR-NK cells infused each time should be no less than 7.5×10\^7 cells, Continuous infusion for 2 days constitutes one course, with 4 courses. The infusion is given every 2 weeks.

You may not qualify if:

• Patients who have received drugs or other cell immunotherapy in other clinical trials within 28 days before the screening period;
• Patients who have had other malignant tumors in the past 5 years;
• Acute illnesses are ongoing, or severe illnesses have occurred in the past 2 years, such as patients with active infections or fever, cardiovascular diseases (Grade III or IV heart failure), mental health issues (such as alcoholism, drug abuse);
• History of immunodeficiency, including HIV-positive status or other acquired, congenital immunodeficiency diseases;
• Organ transplant or organ failure patients, patients receiving immunosuppressive therapy after organ transplantation, or patients taking immunosuppressive drugs long-term;
• Thromboembolic events such as cerebrovascular accidents (including transient ischemic attacks), deep vein thrombosis, and pulmonary embolism within 6 months;
