Clinical Phase III Trial Treosulfan-based Conditioning Versus Reduced-intensity Conditioning (RIC)
Clinical Phase III Trial to Compare Treosulfan-based Conditioning Therapy With Busulfan-based Reduced-intensity Conditioning (RIC) Prior to Allogeneic Haematopoietic Stem Cell Transplantation in Patients With AML or MDS Considered Ineligible to Standard Conditioning Regimens

Intervention / Treatment
Detailed Description
To compare efficacy and safety of Treosulfan-based conditioning (test) with i.v. Busulfan-based reduced intensity conditioning (reference).
The statistical aim of the study is to show non-inferiority with respect to:
Event-free survival (EFS) within 2 years after transplantation. Events are defined as relapse of disease, graft failure or death (whatever occurs first).
- Comparative evaluation of incidence of CTC grade III/IV mucositis/stomatitis between day -6 and day +28
- Comparative evaluation of overall survival (OS) and cumulative incidence of relapse (RI) as well as non-relapse mortality (NRM) and transplantation-related mortality (TRM)within 2 years after transplantation
- Comparative evaluation of day +28 conditional cumulative incidence of engraftment
- Comparative evaluation of day +28 and day +100 incidence of complete donor-type chimerism
- Comparative evaluation of cumulative incidence of acute and chronic GvHD within 2 years after transplantation
- Comparative evaluation of incidence of other CTC grade III/IV adverse events between day -6 and day +28
Individual patients will be followed-up for at most 2 years after transplantation. Three confirmatory interim evaluations and one final analysis are planned, which allow to stop the trial as soon as the question of non-inferiority is answered (as outlined below). In addition, post-surveillance with respect to OS and EFS will be conducted one year after transplantation of the last randomised patient.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
Patients with acute myeloid leukaemia acc. to WHO, 2008 (AML in complete remission at transplant, i.e. blast counts < 5 % in bone marrow) or myelodysplastic syndrome acc. to WHO, 2008 (MDS with blast counts < 20 % in bone marrow during disease history) indicated for allogeneic haematopoietic progenitor cell transplantation but considered to be at increased risk for standard conditioning therapies according to the following criteria:
- patients aged ≥ 50 years at transplant and / or
- patients with a HCT-CI score > 2 [acc. to Sorror et al., 2005]
- Availability of an HLA-identical sibling donor (MRD) or HLA-identical unrelated donor (MUD). Donor selection is based on molecular high resolution typing (4 digits) of class II alleles of the DRB1 and DQB1 gene loci and molecular (at least) low resolution typing (2 digits) of class I alleles (i.e., antigens) of the HLA- A, B, and C gene loci. In case, no class I and class II completely identical donor (10 out of 10 gene loci) can be identified, one antigen disparity (class I) and/or one allele disparity (class II) between patient and donor are acceptable. Conversely, disparity of two antigens (irrespective of the involved gene loci) cannot be accepted. These definitions for the required degree of histocompatibility apply to the selection of related as well as of unrelated donors.
- Adult patients of both gender, age 18 - 70 years
- Karnofsky Index ≥ 60 %
- Written informed consent
- Men capable of reproduction and women of childbearing potential must be willing to consent to using a highly effective method of birth control such as condoms, implants, injectables, combined oral contraceptives, IUDs, sexual abstinence or vasectomised partner while on treatment and for at least 6 months thereafter
Exclusion Criteria:

- patients with severe pulmonary impairment, DLCOsb (Hb-adjusted)/or FEV1 < 50 % or severe dyspnoea at rest or requiring oxygen supply
- patients with severe cardiac impairment diagnosed by echocardiography and LVEF < 40 %
- patients with severe hepatic impairment indicated by hyperbilirubinaemia > 3 x ULN or ALT / AST > 5 x ULN

- Participation in another experimental drug trial within 4 weeks prior to day -6 of the protocol
- Non-cooperative behaviour or non-compliance
- Psychiatric diseases or conditions that might compromise the ability to give informed consent
