Internationale Studie zur Behandlung von Kindern und Jugendlichen mit Therapie-resistenter oder rezidivierender akuter myeloischer Leukämie.

Disease category: Leukemia

Brief description of trial (Data source: BASEC)

Die akute myeloische Leukämie (AML) ist eine bösartige Erkrankung des blutbildenden Systems. Sie führt zu einer zum Teil massiven Vermehrung unreifer Zellen „Blasten“ im Knochenmark.
Diese Studie hat das Ziel, die Heilungsrate von Kindern mit Rückfall einer AML weiter zu verbessern. Bei dieser Studie soll festgestellt werden, ob eine einmalige zusätzliche intravenöse Gabe des Medikamentes Mylotarg® (GO) zu der gängigen intravenösen Therapie mit den Medikamenten Fludarabin, liposomalem Daunorubicin und Cytarabin, ein besseres Ansprechen auf die Therapie erzielt.
Der Ablauf der Behandlung und die notwendigen Untersuchungen sind nicht spezifisch für diese Studie, sondern bei der Durchführung jeder AML Chemotherapie erforderlich. Insgesamt besteht die Chemotherapie aus kombinierten Medikamenten (Fludarabin, Cytarabin, liposomales Daunorubicin), die über einen Zeitraum von 6 bis 8 Tagen gegeben werden (Chemotherapieblock). Danach ist jeweils eine Pause vorgesehen, in der die Medikamente wirken und die Patienten sich von den Nebenwirkungen erholen. Abhängig vom Ansprechen der Leukämie auf die Behandlung und der allfälligen Verfügbarkeit eines Blut-Stammzell- oder Knochenmarkspenders, werden insgesamt zwei oder drei Chemotherapieblöcke verabreicht.
Die Patienten erhalten entweder die Standardtherapie mit oder ohne GO. Die Zuteilung wird per Zufall entschieden.

Primary end point (Data source: WHO)

Main Objective: Determination of the initial efficacy of GO when added to DX-FLA in the first course of reinduction chemotherapy in children with relapsed or refractory AML compared to DX-FLA only. Activity will be measured by the percentage of patients having not more than 20% blasts in the bone marrow (BM) before the second induction course.;
Secondary Objective: 1.Determine clinical outcome in both treatment arms, defined as refractory disease, complete remission rate after 2 reinduction courses, cumulative incidence of relapse, EFS and OS.
2.Incidence of treatment related mortality and toxicity of GO according to the CTCAEv4 when added to DX-FLA, in terms of mucosal toxicity, BM aplasia, liver toxicity with special respect to the development of VOD, also called SOS), short- and long-term cardiotoxicity and other adverse reactions, as compared to patients treated with DX-FLA only.
3.Identification of additional prognostic factors in pediatric relapsed AML, other than early treatment response, cytogenetics and duration of CR1.
4.Establish a diagnostic and logistic network to obtain an individual characterization of AML based on morphology, immunophenotype, type I and II mutations, signal pathway activation, and monitoring of MRD / treatment response for individualized stratification to targeted therapy within a short timeframe.
;Primary end point(s): The percentage of bone marrow blasts after the first course of reinduction chemotherapy on day 28” (in practice anytime between day 28 and 42 after start of first reinduction chemotherapy and before the start of the second reinduction course) given as = 20% or > 20%.;Timepoint(s) of evaluation of this end point: day 28” (before the start of the second reinduction course)

Secundary end point (Data source: WHO)

Secondary end point(s): 1. Determine incidence of refractory disease, CR/CRi rates after 2 courses and efficacy (cumulative incidence of relapse, event-free survival, and overall survival) in the different study arms
2. Determine the toxicity of GO (Mylotarg®) when added to DX-FLA in terms of BM aplasia, liver toxicity including VOD, cardiotoxicity, mucosal toxicity and other adverse reactions according to CTCAEv4 which are considered to be relevant in relapsed AML and the proposed therapy when compared to treatment with DX-FLA only.
3. Identify additional prognostic factors in pediatric relapsed AML, other than early treatment response, cytogenetics and duration of CR1.
4. Provide individual biological characterization of leukemia (morphology, immunophenotype, cytogenetics, molecular genetics and activated signalling pathways), for future individualized stratification to targeted therapy.
Timepoint(s) of evaluation of this end point: 1.: After second reinduction course
2.: Begin of treatment - Day 34 (or before the start of the second reinduction course)
3-4: Begin of treatment - after second reinduction course
