- Ages 18 to 70 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- 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.

About this study
Official title: 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
This randomized allogeneic transplantation protocol compares i.v. Treosulfan-based conditioning therapy with reduced intensity i.v. Busulfan-based conditioning in adult AML and MDS patients at increased risk for standard conditioning therapies. The protocol is based on results of previous phase I/II trials evaluating Treosulfan/Fludarabine conditioning prior to allogeneic haematopoietic stem cell transplantation. The reference arm (reduced intensity i.v. Busulfan/Fludarabine) is considered to be accepted medical practice for the study patient population.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Busulfan and Treosulfan in people with Acute Myeloid Leukemia and Myelodysplastic Syndrome, run by medac GmbH at 33 sites in 6 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 33 sites in Germany, Italy, France, Poland, Finland and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Event-free survival (EFS) (time frame: within 2 years after transplantation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00822393, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2020.
