About this study
Official title: Allogeneic Hematopoietic Cell Transplantation With Cyclophosphamide, Fludarabine, and Antithymocyte Globulin in Lower Risk Myelodysplastic Syndrome Phase 2 Extension Study
To evaluate the efficacy of the conditioning regimen with cyclophosphamide, fludarabine, and antithymocyte globulin (CyFluATG) for allogeneic hematopoietic cell transplantation (HCT) in patients with lower risk myelodysplastic syndrome (MDS). The efficacy of the treatment will be measured in terms of engraftment and non-relapse mortality (NRM).
Read the detailed description
- This is a prospective, phase 2 extension study
- Conditioning regimen A. Cyclophosphamide 50 mg/kg/day i.v. daily on days -3 and -2 (for 2 days) B. Fludarabine 30 mg/m2/day i.v. daily on days -7to -2 (for 6 days) C. Antithymocyte globulin (Thymoglobulin) 1.5 mg/kg/day (for HLA-matched sibling donor HCT) or 3.0 mg/kg/day (for other alternative donor HCT) i.v. daily on days -3 to -1 (for 3 days) D. Methylprednisolone 2 mg/kg i.v. daily on days -4 to -1 (for 4 days)
- Harvest and infusion of donor hematopoietic cells A. Harvested peripheral blood mononuclear cells of donors via leukapheresis will be infused to recipients on day 0. Additional infusion on day 1 can be made based on the judgement of attending physician.
- GVHD prophylaxis A. Cyclosporine: 1.5 mg/kg i.v. every 12 hours beginning on day -1 and changed to oral dosing (with twice the i.v. dose) when oral intake is possible.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing cyclophosphamide, fludarabine, and antithymocyte globulin in people with Myelodysplastic Syndromes, run by Asan Medical Center at 1 site in South Korea.
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 7 inclusion and 6 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: under way, not looking for participants, as of the sponsor's last update on 24 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. 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?
This study is still under way. Results are not available in the source record yet.
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?
engraftment and non-relapse mortality (time frame: 8 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 24 Oct 2023.
