Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: Following treatment cycle 2; Main Objective: 1. To assess the safety and tolerability of HU at three different dose-levels added to standard AML therapy consisting of ara-C and daunorubicin (frequency and severity of toxicities; dose-finding) 1. To assess the effect of HU added to standard AML therapy consisting of ara-C and daunorubicin on the rate of negative minimal residual disease (MRD-negativity) after the second standard chemotherapy cycle ; Secondary Objective: 1. To assess the time to haematopoietic recovery after each chemotherapy treatment cycle 2. To assess the effect of HU added to standard AML therapy consisting of ara-C and daunorubicin on ara-CTP accumulation in peripheral blasts 3. To assess the effect of HU added to standard AML therapy on remission (CR/CRi/MLFS) 4. To assess the effect of HU added to standard AML therapy on event-free survival (EFS) 5. To assess the effect of HU added to standard AML therapy on relapse-free survival (RFS) two years after diagnosis 6. To assess the effect of HU added to standard AML therapy on overall survival (OS) two years after diagnosis 7. To assess the role of SAMHD1 protein expression for secondary objectives 2-6 ; Primary end point(s): • MRD-negativity after cycle 2 Definition of MRD: malignant blasts as a percentage of total bone-marrow cells and as a percentage of the whole white blood cell compartment. These percentages are calculated based on the frequency of cells with an aberrant phenotype. It is nowadays well established that minimal residual disease (MRD) can be a clinical surrogate marker for survival, in particular relapse-free survival.

Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Safety and tolerability (frequency and severity of non-hematological toxicities). • Time to hematopoietic recovery (ANC 0.5 and 1.0 x 109/L; platelets 50 x 109/L) after each chemotherapy treatment cycle, defined as the time from the start of the cycle until recovery. • Efficacy profile (response rate (CR, CRi, MLFS), event free survival (EFS), relapse-free survival (RFS), and overall survival (OS)) ; Timepoint(s) of evaluation of this end point: MRD-negativity after cycle 2 response rate (CR, CRi, MLFS, PR) after cycle 2 event free survival (EFS) and overall survival (OS) after the end of the trial ara-CTP amounts after first and second ara-C infusion on day 1 of cycle 1 | — |
