Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the efficacy of haploidentical NK-cell based consolidation with standard cytarabine based consolidation in elderly patients suffering from AML with high risk of fatal relapse and no option for allogeneic stem cell transplantation (SCT). ;Secondary Objective: - To compare the time to relapse (TTR), the cumulative incidence of relapse (CIR) and relapse-free survival (RFS) between the two study groups - To investigate the yield and purity of NK cells (CD3-CD56+) after CD3 de-pletion and CD56 enrichment - To investigate patients NC cell recovery, NK cell chimerism, NK phenotype and functional capacity of NK cells at various time points after infusion - To compare tolerability and safety of the two interventions;Primary end point(s): 2-year overall survival;Timepoint(s) of evaluation of this end point: 2-year after study inclusion | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Time to relapse (TTR), cumulative incidence of relapse (CIR), • Relapse-free survival (RFS), • Yield and purity of NK cells (CD3-CD56+) after CD3 depletion and CD56 enrichment, • Patient NK cell recovery • NK cell chimerism • NK phenotype s • Clinical performance (ECOG score) • Incidence and severity of GVHD • Incidence of AEs and SAEs;Timepoint(s) of evaluation of this end point: up to 2 years from study inclusion | — |
