Brief Summary

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.

Detailed Description

This open-label phase I, multi-center study aims to determine in relapsed/refractory acute myeloid leukemia or myelodysplastic syndrome patients the recommended dose of CYAD-02 after a non-myeloablative preconditioning chemotherapy followed by a potential CYAD-02 consolidation cycle for non-progressive patients.

During dose escalation, three prespecified dose-levels of CYAD-02 will be evaluated in three cohorts. Patient enrollment during dose-escalation will be staggered according to the Fibonacci 3+3 design and extension of cohorts II and III will be done in parallel. The first CYAD-02 infusion will be administered after prior non-myeloablative preconditioning chemotherapy (CYFLU) administered on three consecutive days.

Non-progressive patients meeting the criteria specified below may receive a consolidation cycle with three additional CYAD-02 infusions at a 2-week interval without prior preconditioning.

For all patients who received at least one CYAD-02 infusion, the overall study duration will be approximately 15 years.

Dose Escalation Dose Level 1CYAD-02in case of no dose limiting toxicity (DLT) and no replacement of patients, 3 consecutive patients at the dose of 1x10e8 of CYAD-02 per infusion post preconditioning non-myeloablative chemotherapy according to a 3+3 study design. The preconditioning therapy consists of 3 consecutive days of cyclophosphamide (300 mg/m²/day) and fludarabine (30 mg/m²/day), two days before the CYAD-02 infusion. In case of no progression at D22, the patient is eligible to receive a consolidation cycle of 3 additional CYAD-02 infusion at the same dose level, without prior preconditioning chemotherapy.
