Donor Derived CD117 CAR-T Cells in the Treatment of R/R Acute Myeloid Leukemia

Inclusion Criteria12

• \. Patients with a histologically or immunophenotypically confirmed diagnosis of CD117-positive Acute Myeloid Leukemia (AML).
• \. 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.
• \. Presence of \>5% bone marrow blasts (by morphology) and/or \>1% (by flow cytometric analysis).
• \. Total bilirubin ≤1.5 × ULN (≤51 μmol/L) ALT and AST ≤3 × ULN Serum creatinine ≤1.5 × ULN (≤176.8 μmol/L)
• \. Left ventricular ejection fraction (LVEF) ≥50% as assessed by echocardiography.
• \. Oxygen saturation ≥92% on room air.
• \. Life expectancy ≥3 months.
• \. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
• \. 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).
• \. Voluntary participation, understanding of the study procedures, and provision of written informed consent by the patient or their legally authorized representative.
