Eligibility Criteria

Inclusion

  • Informed Consent: Willing and able to provide written informed consent, with commitment to comply with scheduled visits, study treatment, laboratory tests, and other trial procedures.
  • Age: ≥18 years, regardless of gender.
  • Diagnosis: Pathologically confirmed myeloid malignancy (including but not limited to AML or MDS) meeting relapsed/refractory criteria:
  • Relapsed Disease: Reappearance of leukemic cells in peripheral blood, bone marrow blasts \>5%, or extramedullary relapse after achieving CR/CRi with ≥2 lines of salvage therapy.
  • Refractory Disease: Failure to achieve CR/CRi after ≥2 cycles of standard intensive chemotherapy.
  • Antigen Expression: Tumor cell positivity for CD33, CD123, and/or CLL-1 confirmed by immunohistochemistry (IHC) or flow cytometry.
  • Life Expectancy: ≥3 months from the date of informed consent signing. Hematologic Criteria: Hemoglobin ≥70 g/L (transfusion permitted).
  • Organ Function:
  • Renal: Serum creatinine ≤1.5×ULN. Cardiac: Left ventricular ejection fraction (LVEF) ≥50%. Pulmonary: Oxygen saturation \>90% on room air. Hepatic: Total bilirubin ≤1.5×ULN; ALT/AST ≤2.5×ULN. Performance Status: Eastern Cooperative Oncology Group (ECOG) performance status score 0-2.

Exclusion

  • Cardiac Dysfunction: Severe cardiac insufficiency with left ventricular ejection fraction (LVEF) \<50%.
  • Pulmonary Disease: History of severe pulmonary dysfunction (e.g., chronic respiratory failure, interstitial lung disease, or pulmonary hypertension requiring oxygen therapy).
  • Concurrent Malignancy: Active/progressive malignancy other than myeloid neoplasms (exceptions: adequately treated non-melanoma skin cancer or carcinoma in situ).
  • Uncontrolled Infection: Active severe infection requiring systemic antimicrobial therapy (antibacterial, antiviral, or antifungal) without clinical resolution.
  • Immune Disorders:
  • Severe autoimmune disease requiring immunosuppressive therapy within 6 months. Primary immunodeficiency disorders (e.g., common variable immunodeficiency, severe combined immunodeficiency).
  • Viral Infections:
  • Active hepatitis B (HBV-DNA ≥2000 IU/mL) or hepatitis C (HCV-RNA positive). HIV infection, AIDS, or untreated syphilis (confirmed by serological testing). Hypersensitivity: History of severe allergic reaction (Grade ≥3) to biological products, including antibiotics.
  • Transplant Complications: Allogeneic hematopoietic stem cell transplant recipients with:
  • Acute graft-versus-host disease (GvHD) ≥ Grade II within 3 months. Ongoing immunosuppressive therapy for GvHD within 4 weeks.
  • General Exclusion:
  • Any physical, psychiatric, or laboratory abnormality that may:
  • Significantly increase study risk (e.g., uncontrolled diabetes, NYHA Class III/IV heart failure).
  • Compromise protocol compliance or data interpretation. Investigator-determined unsuitability for trial participation.
