Eligibility Criteria

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Age: ≥ 3 years old and ≤ 75 years old, male or female;
  • Meet the diagnostic criteria for recurrent AML specified in the guidelines for diagnosis and treatment of acute myelogenous leukemia (relapse/refractory) in China (2017): leukemic cells reappear in peripheral blood or bone marrow MRD \> 0.1% after complete remission (CR), including relapse after allogeneic hematopoietic stem cell transplantation or extramedullary leukemic cell infiltration.
  • Meet the diagnostic criteria for refractory AML specified in the guidelines for diagnosis and treatment of acute myelogenous leukemia (relapse/refractory) in China (2017): 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;
  • Life expectancy ≥ 12 weeks from the time of enrollment;
  • 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;
  • Flow cytometry check for NKG2D ligand expression on the surface of cancer cells as a reference for patient selection;
  • The patient's peripheral superficial vein is accessible for IV insertion and blood draws;
  • No other serious diseases that conflict with this protocol (e.g., autoimmune diseases, immunodeficiency, organ transplantation);
  • No history of other malignant tumors;12. 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; 14. Written informed consent form must be signed by the patient or the patient's immediate family members before enrollment.

You may not qualify if:

  • Acute promyelocytic leukemia (Type M3);
  • Patients with cardiac insufficiency, patients with liver and renal insufficiency;
  • Patients with other malignant tumors need to be treated;
  • Poorly controlled hypertension (systolic blood pressure \>160 mmHg and/or diastolic blood pressure \>90 mmHg) or clinically significant cardiovascular and cerebrovascular diseases such as cerebrovascular accident (within 6 months before signing the informed consent form), myocardial infarction (within 6 months before signing the informed consent), unstable angina, congestive heart failure, or severe arrhythmias that cannot be controlled with drugs or have a potential impact on research treatment;
  • Patients suffering from other hematologic diseases (such as hemophilia, myelofibrosis, etc., which researchers consider unsuitable for enrollment);
  • Patients with diffuse vascular internal coagulation;
  • Patients with concomitant serious infection or other serious underlying medical condition;
  • Patients with variable immunodeficiency and autoimmune diseases;
  • Patients who have severe allergic diseases;
  • Clinical symptoms of brain dysfunction or severe mental illness that can not understand or follow the research protocol;
  • Have participated in clinical trials of other drugs within 4 weeks or within 21 days of surgery;
  • Have received cell therapy in the previous 1 month;
  • Have received hormonal drug therapy in the previous 14 days;
  • Known human immunodeficiency virus (HIV) seropositivity or active hepatitis B or C infection or syphilis;
  • Have received organ transplants (excluding stem cell transplant patients);
  • +4 more criteria
