Summary
Brief summary (as posted)
GATLA 8-AML´07 trial is an multicenter phase III dose-optimization trial for the treatment of acute myeloid leukemias in children and adolescents. Patients are treated with a combination of intensive chemotherapy in combination with intrathecal-injection by CNS and haematopoietic stem cell transplantation. The patients are stratified in a standard-group (SR) and a high risk-group (HR). SR was defined as FAB (French-American-British) M1/M2 with Auer rods; FAB M4eo or favorable cytogenetics \[t(8;21)/AML1-ETO or inv(16) or t(16;16) and/or CBFB/MYH11)\]; bone marrow blasts ≤5% on day 15. HR was defined as all others. SR patients were reclassified to the HR group if FLT3-ITD positive. Based on the experience of the BFM group, it was decided to randomly evaluate whether the six-drug conventional consolidation stage can be replaced with the use of a consolidation based by block therapy on drugs of proven efficacy in AML with the aim of reducing residual disease, and the toxicity of this stage. Patients are randomized once the double induction is completed into those who will receive the conventional consolidation phase and those who will receive consolidation with the combination of high doses cytarabine and two different anthracyclines sequentially.
