CART123 T Cells in Relapsed or Refractory CD123+ Hematologic Malignancies: A Dose Escalation Phase I Trial

Is NCT06765876 recruiting? Yes, currently enrolling (May 2026). This Early Phase 1 trial studies Autologous CAR123 T lymphocytes for leukemia, myeloid, acute(aml).

Early Phase 1RecruitingInstitute of Hematology and Blood Transfusion, Czech RepublicNCT06765876Data as of May 2026

Treatment: Autologous CAR123 T lymphocytesAdult patients with refractory or relapsed CD123+ hematologic malignancies, including acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia, or blastic plasmocytoid dentritic cell neoplasm will be recruited in the trial. CART123 cells will be manufatured from blood of each patient. During the production of CAR123 cells, patients may receive appropriate bridging therapy. After cells are produced, participants will undergo a single course of lymphodepleting chemotherapy and receive a single dose of CAR123 T cells. The trial will establish the recommended dose for further studies, either the Maximum Tolerated Dose (MTD) or Maximum Feasible Dose (MFD). Patients must be eligible for hematopoietic stem cell transplantation in order to participate in the trial.
