The prospective clinical phase II protocol MC-FludT.16/NM is to be conducted to verify safety and efficacy of Treosulfan-based conditioning compared to Busulfan-based conditioning in paediatric patients. Based on the given clinical experience with either Treosulfan-based or Busulfan-based conditioning in combination with Fludarabine no increased risk for graft failure is expected in paediatric patients. A potential benefit for study patients is expected with respect to a probably low non-haematological toxicity of treatment compared to myeloablative TBI-based conditioning or high-dose Busulfan-based conditioning in combination with Cyclophosphamide.
However, the allogeneic HSCT procedure itself potentially involves serious risks with regard to severe or life-threatening conditions like graft versus host disease (GvHD) and/or infectious complications as well as graft failure.
In summary, the primary goal of this study is to evaluate the Treosulfan-based myeloablative conditioning regimen as an alternative in children and to contribute to the current PK model for Treosulfan to be able to finally give age (or body surface area [BSA]) dependent dose recommendations. The treatment regimens given in the protocol MC-FludT.16/NM are based on sufficient clinical safety and efficacy data. Considering the vital indication for allogeneic HSCT of the selected patient population, the risk-benefit assessment seems to be in favour of the study conduct.
Moreover, planned interim analyses will ensure the early identification of unexpected risks. Therefore, the conduct of the protocol MC-FludT.16/NM is considered reasonably justified.

|Official Title:||Clinical Phase II Trial to Compare Treosulfan-based Conditioning Therapy With Busulfan-based Conditioning Prior to Allogeneic Haematopoietic Stem Cell Transplantation (HSCT) in Paediatric Patients With Non-malignant Diseases|

|Estimated Primary Completion Date :||December 2020|
|Estimated Study Completion Date :||December 2022|
One Treosulfan dose per day administered i.v. on three consecutive days (-6, -5 and -4); given over 2 hours as part of background conditioning prior to allogeneic stem cell transplantation.
The dose has to be calculated as follows:
If the BSA (m2) is equal or less than 0.3, the Treosulfan dose should be 10g/m2/day.
If the BSA (m2) is greater than 0.3 and equal or less than 0.8, the Treosulfan dose should be 12g/m2/day.
If the BSA (m2) is greater than 0.8, the Treosulfan dose should be 14g/m2/day.
Active Comparator: Busulfan
Total daily Busilvex dose (3.2 to 4.8 mg/kg/day, based on body weight) according to authorised dosage for children and adolescents administered i.v. as part of the background conditioning regimen on four consecutive days (days -7, -6, -5 and -4); given in 1, 2, or 4 portions per day according to the respective hospital's standard.
- Comparative evaluation of freedom from transplant (treatment)-related mortality (TRM), defined as death from any transplant-related cause from the day of first administration of study medication (day -7) until day +100 after HSCT. [ Time Frame: day -7 to day +100 ]
