简要总结
This trial will explore the maximum tolerated dose of cord blood NKG2D CAR-NK in the treatment of recurrent refractory acute myeloid leukemia in a dose-escalation manner, and observe its clinical safety and efficacy.
详细描述
This is a single arm, open-label, Phase 1 study initiated with 3 cohorts:
Cohort 1: 2×10∧6/kg CAR-NK cells, 2 infusions on Day 0 and Day 7 Cohort 2: 6×10∧6/kg CAR-NK cells, 2 infusions on Day 0 and Day 7 Cohort 3: 18×10∧6/kg CAR-NK cells, 2 infusions on Day 0 and Day 7

入选标准
- •Age: ≥ 10 years old and ≤ 75 years old, male or female;
- •Meet the diagnostic criteria for recurrent AML: detection of leukemia cells after complete remission (CR) or >0.1% of leukemia cells in bone marrow, including recurrence after allogeneic hematopoietic stem cell transplantation, or extramedullary infiltration of leukemia cells;
- •Initial cases with failure of 2 lines of standard treatment; patients who relapsed within 12 months after consolidation intensification after CR; recurrence in 12 months and no respond to conventional chemotherapy; 2 or more recurrences; persistent extramedullarial leukemia;
- •Patients currently have no effective treatment options, such as chemotherapy or allogeneic hematopoietic stem cell transplantation, or patients voluntarily choose to infuse NKG2D CAR-NK cells as the first treatment option;
- •Physical status assessment (ECOG-PS) of the Eastern Oncology Collaborative Group is 0-2 points;
- •Estimated survival > 3 months
- •Flow cytometry check for NKG2D ligand expression on the surface of cancer cells for a reference of selecting patients
- •The main organs of the patient are well functioned: (1) cardiac function: no heart disease or coronary heart disease, the patient's cardiac function grade 1-2; (2) liver function: TBIL≦3ULN, AST≦2.5ULN, ALT≦2.5ULN; (3) Renal function: Cr≦1.25ULN;
- •The patient's peripheral superficial vein can meet the needs of intravenous injection;
- •No other serious diseases that conflict with this protocol (e.g., autoimmune diseases, immunodeficiency, organ transplantation);
- •No history of other malignant tumors;
- •Women of childbearing age must be tested negative for pregnancy within 7 days, and subjects of childbearing age must use appropriate contraception during both the trial and for 3 months after the test;
- •Subjects have negative HIV, HBV, HCV, syphilis serology test results

- •Also suffering from other hematologic diseases (such as hemophilia, myelofibrosis, etc., which researchers consider unsuitable for inductees);
- •Diffuse vascular internal coagulation;
- •Concomitant serious infection or other serious underlying medical condition;
- •Have immunodeficiency and autoimmune diseases;
- •Have severe allergic diseases;
- •Clinical symptoms of brain dysfunction or severe mental illness that can not understand or follow the research protocol;
