Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children and adolescents aged 21 years or younger with acute lymphoblastic leukaemia in complete remission who require allogeneic HSCT.
✕Probably not a fit
Patients with non-Hodgkin lymphoma or those who do not meet the inclusion criteria will not benefit from this study.

What this trial studies
This trial investigates the effectiveness of allogeneic stem cell transplantation (HSCT) in children and adolescents diagnosed with acute lymphoblastic leukaemia (ALL) who are in complete remission. The study aims to determine if a chemotherapy-based conditioning regimen can replace total body irradiation (TBI) before HSCT, potentially reducing late complications associated with TBI. It is a multinational, multicenter, controlled, prospective study that involves stratifying patients based on their individual transplantation modalities and donor availability. The trial seeks to gather data from a diverse patient population to improve treatment outcomes for those with high-risk ALL.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment protocols for pediatric ALL, reducing the risk of late complications associated with traditional TBI.
How similar studies have gone: Other studies have shown promise in using chemotherapy-based conditioning regimens, but this specific approach in pediatric ALL is novel and has not been extensively tested.

Inclusion Criteria: Patients with ALL (except for patients with B-ALL) who fulfil the following criteria: * age at diagnosis ≤ 18 years. Age at HSCT ≤ 21 years * indication for allogeneic HSCT * complete remission (CR) before HSCT * written consent of the parents (legal guardian) and, if necessary, the minor patient via "Informed Consent Form" * no pregnancy * no secondary malignancy * no previous HSCT * HSCT is performed in a study participating centre Exclusion Criteria: * patients who do not fulfil the inclusion criteria * Non Hodgkin-Lymphoma * the whole protocol or essential parts are declined either by patient himself/herself or the respective legal guardian * no consent is given for saving and propagation of anonymous medical data for study reasons * severe concomitant disease that does not allow treatment according to the protocol at the investigator's discretion (e.g. malformation syndromes, cardiac malformations, metabolic disorders) * Karnofsky / Lansky score \< 50% * subjects unwilling or unable to comply with the study procedures
