About this study

Official title: Decitabine and Umbilical Cord Blood for Poor Graft Function Post Allogenic Hematopoietic Stem Cell Transplantation

This randomized trial aimed at validating the efficacy and safety of low-dose decitabine, together with umbilical cord blood in PGF post allo-HSCT patients.

Read the detailed description

Poor graft function (PGF), defined by the presence of multilineage cytopenias in the presence of 100% donor chimerism, is a serious complication of allogeneic stem cell transplant (allo-HSCT). Emerging evidence demonstrates that the inadequate stem cells infusion, bone marrow microenvironment and immune dysregulation play a crucial role in maintaining and regulating hematopoiesis. Current therapies remain debatable, including selected CD34+ cells infusion, mesenchymal stromal cells infusion, prophylactic N-acetyl cysteine administration, etc. Thereafter, the investigators conduct a randomized trial aiming at validating the efficacy and safety of low-dose decitabine, together with umbilical cord blood in PGF post allo-HSCT patients.

Patients were eligible if they were diagnosed as PGF at day 28 post-HSCT or later. PGF was defined as two or three cytopenias, absolute neutrophil count ≤ 1.5 × 109/L, platelet count ≤ 30 × 109/L, hemoglobin ≤ 85g/L, lasting for more than 14 consecutive weeks, in the presence of full donor chimerism and primary disease in remission without severe graft-versus- host disease (GVHD) and relapse.

Patients with the following conditions or diagnoses were excluded: allergic to decitabine or any components of frozen preservation of umbilical cord blood; active infections; uncontrolled GVHD; severe organ dysfunction; relapse of underlying malignancies; graft failure. Patients were also excluded if they had received decitabine or participated in other clinical trials within one month before screening.

Hematological improvement is defined as recovery of two or three blood lineages: absolute neutrophil count>1.5 × 109/L, platelet count>30 × 109/L, hemoglobin>85g/L, without G-CSF, red blood cell or platelet infusion.

Hematological response is defined as recovery of three blood lineages: absolute neutrophil count>2.5 × 109/L, platelet count>60 × 109/L, hemoglobin>100g/L, without G-CSF, red blood cell or platelet infusion.

No response: failed to achieve hematological improvement or response.

Being tested
decitabine, umbilical cord blood, Granulocyte-colony stimulating factor, Recombinant human thrombopoietin / thrombopoietin receptor agonist, Recombinant human erythropoietin

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing decitabine, umbilical cord blood and Granulocyte-colony stimulating factor in people with Poor Graft Function, run by The First Affiliated Hospital of Soochow University.

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 4 inclusion and 7 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: opening soon, as of the sponsor's last update on 9 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Contact Yaqiong Tang (18896588075, tangyaqiong@suda.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The treatment response (time frame: day +28). The study lists 2 primary outcomes in all. 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 NCT05669079, which also lists 5 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 9 Jun 2023; AzTrials last refreshed its copy on 30 Oct 2026.
