Design outcomes

Primary

MeasureTime frame
Timepoint(s) of evaluation of this end point: The primary endpoint of the study is event-free survival. This is a time to event endpoint. This cumulative endpoint includes the following events: no achievement of hematological complete remission after induction therapy; no achievement of molecular remission after the last consolidation course (molecular resistance); relapse (hematological/molecular); death including early death (within 30 days after randomization) or development of secondary myelodysplasia or leukemia.;Secondary Objective: - complete remission (CR) , overall survival (OS) and cumulative incidence of relapse (CIR) rates - cumulative incidence of secondary myelodysplastic syndromes or acute myeloid leukaemia - early death during induction - quality of life - toxicity profile - kinetics of MRD - duration of in-patient treatment - health economics ;Main Objective: To compare event-free survival (EFS) of the experimental treatment arm including ATO/ATRA and idarubicin with standard treatment based on ATRA plus chemotherapy (AIDA regimen) in newly diagnosed high-risk APL;Primary end point(s): The primary endpoint of the study is event-free survival.

Secondary

MeasureTime frame
Secondary end point(s): - complete remission (CR), overall survival (OS) and cumulative incidence of relapse (CIR) rates - cumulative incidence of secondary myelodysplastic syndromes or acute myeloid leukaemia - early death during induction - quality of life - toxicity profile - kinetics of MRD - duration of in-patient treatment - health economics ;Timepoint(s) of evaluation of this end point: -whole study
