New chemo combo may lower death risk in child stem cell transplants
NCT ID NCT02349906
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two different chemotherapy drugs (Treosulfan and Busulfan) given before a stem cell transplant in 106 children with serious non-cancer diseases like immune disorders, metabolic diseases, blood disorders, and bone marrow failure. The goal was to see which drug leads to fewer deaths from transplant-related causes in the first 100 days. The approach uses a standard drug (Fludarabine) plus one of the two chemo drugs to prepare the body for donor stem cells.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Non-malignant disease indicated for first myeloablative allogeneic HSCT, including inborn errors of metabolism, primary immunodeficiencies, haemoglobinopathies and bone marrow failure syndromes. 2. First allogeneic HSCT. 3. Available matched sibling donor (MSD), matched family donor (MFD) or matched unrelated donor (MUD). For bone marrow (BM) and peripheral blood (PB) match is defined as at least 9/10 allele matches after four digit typing in human leucocyte antigen (HLA)-A, -B, -C, -DRB1 and DQB1 antigens. For umbilical cord blood (UCB) match is defined as at least 5/6 matches after two digit typing in HLA-A and -B and four digit typing in DRB1 antigens. Exclusion Criteria: 1. Second or later HSCT. 2. HSCT from mismatched donor (less than 9/10 BM/peripheral blood stem cells (PBSC) or less than 5/6 matched cord donor). 3. Preterm newborn infants (\<37 weeks gestational age) and term newborn infants aged 0 - 27 days at time of registration. 4. Obese paediatric patients with body mass index weight (kg)/\[height (m)\]² \> 30 kg/m². 5. Diagnosis of Fanconi anaemia and other chromosomal breakage disorders, radiosensitivity disorders (deoxyribonucleic acid (DNA) Ligase 4, Cernunnos- X-ray repair cross-complementing protein 4 (XRCC4) like factor (XLF), Nijmegen Breakage Syndrome (NBS)) and Dyskeratosis Congenita.
