About this trial

An open-label, phase I, multi-center study to determine in relapsed/refractory (r/r) acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) patients the recommended dose of CYAD-02 after a non-myeloablative preconditioning chemotherapy followed by a potential CYAD-02 consolidation cycle for non-progressive patient. A maximum of 27 r/r AML/MDS patients will be evaluated in this study in case of no dose limiting toxicity (DLT) and no replacement of patients.

Recurrence of disease after a second complete remission, or

Failure to achieve a Complete Response after induction chemotherapy.
