Title Allogeneic Stem Cell Transplantation in Children and Adolescents with Acute Lymphoblastic Leukaemia
Disease Acute lymphblastic leukeamia
Type Open, randomised, multicentre, controlled, prospective phase III study
Problem / Objectives

Background

Children an adolescents with lymphoblastic leukeamia can be cured with modern therapies in more than 80%. Nevertheless patients with high risk or relapsed acute lymphoblastic leukaemia (ALL) have a poor prognosis. For these patients intensive therapy is required after they have achieved remission with multimodal chemotherapy. Allogeneic hematopoietic stem cell transplantation (HSCT) can effectively induce immunological antileukaemic control in patients with ALL by means of the graft-versus-leukaemia effect (GvL), but treatment related mortality (TRM), morbidity and late effects remain serious problems of this treatment modality. In the last decade the short term outcome of 900 children with ALL from more than 60 different study centres who received allogeneic HSCT has improved, due to the use of donors more closely matched by Human leukocyte antigen (HLA) typing, resulting in less severe graft vs host disease (GvHD) and better supportive care. However, the risk of life long complications persists in all children. The observation and documentation of late complications are especially important for children and adolescents.

Rationale

The biggest burdens for children given TBI are the risks of long term complications as secondary malignancies, growth retardation (especially if irradiated below 10 years) and infertility (most common after irradiation during or after puberty). This is why "ALL-SCTped Forum" explores the question, if TBI can be replaced by a less toxic combination of different chemotherapies.

Therapy / Study arms

Stratum 1

All patients > 4 years with a Matched Donor (MD) or Matched Sibling Donor (MSD) will be randomized between the conditioning with VP16/TBI or a Chemo-Conditioning (Busulfan/Thiatepa/Fludarabin or Treosulfan/Fludarabin/R´Thiotepa).

Stratum 2

Patients with a missmatched donor (MMD) will be stratified depending of the treatment centre. As Stem cell source has to be used an classical mismatched donor, a haploidentical donor or, cord blood. MMD transplanted patients receive stratified to the country a non-TBI chemo-conditioning with Fludarabine/Thiotepa/Treosulfan or Fludarabin/Thiotepa/Busulfan.

Patients ≤ 4 years are not randomized and receive a non-TBI chemo-conditioning ( Fludarabin/Thiotepa/Treosulfan or Fludarabin/Thiotepa/Busulfan).
