Clinical Trial Summary

This is an international multicenter open label randomized phase III trial in children with relapsed and refractory acute myeloid leukemia (AML) such a disease. The main purpose of this study is to determine the efficacy and toxicity of liposomal daunorubicin when added to fludarabine, ara-C and G-CSF(FLAG) in children with relapsed and refractory AML.

Description:

Secondary objectives of this trial are:

• To determine the toxicity of liposomal daunorubicin when added to FLAG, in terms of mucosal toxicity, bone marrow aplasia, short- and long-term cardiotoxicity and other side effects as compared to patients treated with FLAG only.

• To determine the long-term clinical outcome prospectively in a large group of children with refractory and relapsed acute myeloid leukemia.

• To determine the changes in minimal residual disease over time, and the prognostic significance of minimal residual disease determined at various time-points.

• To determine the relation between in vitro cellular drug resistance and clinical and cell biological features, minimal residual disease and clinical outcome in this patient group

• To determine the pharmacokinetics of liposomal daunorubicin in relation to its toxicity and efficacy

Reinduction treatment will be done with 2 courses of combination chemotherapy, with FLAG (fludarabine, ara-C and G-CSF) in both courses as standard treatment. In the first course there will be a randomisation for liposomal daunorubicin (DaunoXome®) to be added or not. The second course should always concern FLAG. If patients have > 20% of blasts in the bone marrow after the 1st course, or if they are not in complete remission (CR) after the 2nd course, they will go off protocol. Patients in CR after reinduction treatment can immediately proceed to stem cell transplantation. Consolidation chemotherapy should be given if SCT is delayed. A 3rd course of intensive chemotherapy (VP16 and continuous infusion with cytarabine) is the general recommendation. In selected patients, a low intensity consolidation may be preferred, and such a schedule is described as well. The type of SCT is based on the risk-group. Preferably, a matched sibling donor (MSD) SCT is performed. If a MSD is not available all patients are candidates for a matched unrelated donor (MUD) SCT. If a MUD is also not available, patients with primary refractory disease, early relapse (within 1 year from diagnosis), or greater than or equal to 2nd relapse, are candidates for the more experimental haplo-identical donor (HID) SCT in view of the dismal prognosis. However, patients with a late relapse (>1 year from initial diagnosis) have a better prognosis and should be offered an autologous SCT if a MSD or MUD SCT is not possible. Only in case of autologous SCT, maintenance treatment and/or adjuvant immunotherapy could be considered.
