Egyéb

• 6. The proiferation rate is less than 5 times response to CD3/CD28 co-stimulation signal;
• 9. Any situation that researchers believe may increase the risk to the subjects or interfere with the trial results.

• 1. Patients with a histologically or immunophenotypically confirmed diagnosis of CD117-positive Acute Myeloid Leukemia (AML).
• 2. Diagnosis must meet the 2016 WHO classification criteria for AML and fulfill the definitions for relapsed or refractory disease per the *Chinese Guidelines for the Diagnosis and Management of Relapsed/Refractory Acute Myeloid Leukemia (2017 Edition)*, with no available suitable standard therapeutic options or registered clinical trials.
• a). Relapsed AML: Defined as the reappearance of leukemic blasts in the peripheral blood, bone marrow blast count >5% (when assessed morphologically, after excluding regenerative changes post-consolidation chemotherapy), or development of extramedullary disease after achieving a Complete Remission (CR).
• b). Refractory AML (meeting at least one criterion): Failure to achieve CR following two cycles of standard induction therapy in newly diagnosed patients; relapse within 12 months after CR following consolidation therapy; relapse beyond 12 months that fails to respond to conventional salvage chemotherapy; ≥2 relapses; or persistent extramedullary leukemia.
• 3. Presence of >5% bone marrow blasts (by morphology) and/or >1% (by flow cytometric analysis).
• 4. Total bilirubin ≤1.5 × ULN (≤51 μmol/L) ALT and AST ≤3 × ULN Serum creatinine ≤1.5 × ULN (≤176.8 μmol/L)
• 5. Left ventricular ejection fraction (LVEF) ≥50% as assessed by echocardiography.
• 6. Oxygen saturation ≥92% on room air.
• 7. Life expectancy ≥3 months.
• 8. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
• 9. For patients of childbearing potential: Agreement to use highly effective contraception from screening, throughout the study treatment period, and for at least 6 months after the cell infusion (due to unknown risks to the fetus).
• 10. Voluntary participation, understanding of the study procedures, and provision of written informed consent by the patient or their legally authorized representative.
