About this study
Official title: Treatment of Patients With MDS or AML With an Impending Hematological Relapse With Azacitidine (Vidaza)
Assessment of efficacy of azacitidine to prevent a relapse
Read the detailed description
Analysis of the effectiveness of azacitidine 6 months after start of therapy to prevent a hematological relapse in MDS or AML patients with significant residuals or an increase of minimal residual disease (MRD) which is defined as:
- decrease of CD34 donor chimerism (<80%) after allogeneic related or unrelated HSCT in CD34+ or CD117+ MDS or AML or

- persistence of the (above) MRD level >1% after conventional chemotherapy or allogeneic HSCT
- tolerance of azacitidine

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Azacitidine in people with Acute Myelocytic Leukemia and Myelodysplastic Syndrome, run by Technische Universität Dresden at 11 sites in Germany.
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 10 inclusion and 19 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 15 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Germany. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Number of patients with hematological relapse 6 months after start of treatment with azacitidin (time frame: 6 months after end of treatment). 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 NCT01462578, which also lists 2 linked publications.
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 15 Nov 2021.
