About this study

Official title: G-CSF+DAC+BUCY vs. G-CSF+DAC+BF Conditioning Regimen for Patients With High-risk MDS Undergoing Allogeneic Hematopoietic Stem Cell Transplantation

Allo-HSCT is the most effective way to cure high-risk MDS patients. At present, the best conditioning regimen for high-risk MDS patients undergoing allo-HSCT remains in discussion. In this prospective study, the safety and efficacy of G-CSF+DAC+BUCY and G-CSF+DAC+BF conditioning regimens in high-risk MDS patients undergoing allo-HSCT are evaluated.

Read the detailed description

Allo-HSCT is the most effective way to cure high-risk MDS patients. At present, the best conditioning regimen for high-risk MDS patients undergoing allo-HSCT remains in discussion. A previous study by the investigators has showed that G-CSF +DAC+BUCY conditioning regimen could reduce the relapse and improve the survival compared with BUCY conditioning regimen, while the two conditioning regimens both have high non-relapse mortality (NRM). Several retrospective and prospective studies have demonstrated that BF conditioning regimen has a lower NRM compared with BUCY conditioning regimen, while the relapse and survival are similar in patients undergoing BF and BUCY conditioning regimens. Based on the above, the investigators design the prospective randomized controlled study to evaluate the safety and efficacy of G-CSF+DAC+BUCY and G-CSF+DAC+BF conditioning regimens in high-risk MDS patients undergoing allo-HSCT.

Being tested
Granulocyte Colony-Stimulating Factor(G-CSF), Decitabine (DAC), Busulfan, Fludarabine (FLU), Cyclophosphamide (CY)

    Decitabine was administered at 20mg/m2/day on days -14 to -10.

  • BusulfanDrug

    Busulfan was administered at 3.2 mg/kg/day on days -7 to -4 in G-CSF+DAC+BUCY group.

    Fludarabine was administered at 30 mg/m2/day on days -7 to -3.

  • Cyclophosphamide (CY)Drug

    Cyclophosphamide was administered at 60 mg/kg/day on days -3,-2.

  • Busulfan (BU)Drug

    Busulfan was administered at 3.2 mg/kg/day on days -6 to -3 in G-CSF+DAC +BF group.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Granulocyte Colony-Stimulating Factor(G-CSF), Decitabine (DAC) and Busulfan in people with Myelodysplastic Syndrome and Allogeneic Hematopoietic Stem Cell Transplantation, run by Nanfang Hospital, Southern Medical University at 1 site in China.

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 5 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 21 Mar 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 China. 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 combined 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.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Li Xuan (+86-020-62787883, 356135708@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Non-relapse mortality (NRM) (time frame: 1 year). 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 21 Mar 2023.
