About this study
Official title: Mesenchymal Stem Cells From Third-party Donors for Treatment of Poor Graft Function After Allogeneic Hematopoietic Stem Cell Transplantation
The purpose of this study is to evaluate the utility of treating patients experiencing poor graft function after allogeneic hematopoietic stem cell transplantation with ex-vivo-expanded BM-drived mesenchymal stem cells from third-party donors. Our first objective was to evaluate the effect of such treatment on poor graft function, and second object was to investigate the safety of such treatment.
Read the detailed description
Allogeneic hematopoietic stem cell transplantation(allo-HSCT) can cure many hematologic diseases. Although good progress has been made in the prevention and treatment of side effects associated with transplantation, poor graft function (PGF) remains an important complication that occurs in 5-27% of patients, and is associated with considerable morbidity and mortality related to infections or hemorrhagic complications. Treatment of PGF usually involves the prescription of hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF), or repeat transplantation, but these methods are associated with short-term effect and a significant risk of graft-versus-host disease（GVHD） development, respectively.
Mesenchymal stem cells (MSCs) are a form of multipotent adult stem cells that can be isolated from bone marrow (BM), adipose tissue, and cord blood. Clinical applications of human MSCs are evolving rapidly with goals of improving hematopoietic engraftment, preventing and treating graft-versus-host disease after allo-HSCT and so on. However, the efficacy of treatment of PGF that develops after allo-HSCT using expanded BM-derived MSCs from a third-party donor is rarely reported. If such treatment could be shown to be effective and safe, BM-derived MSCs could potentially be used as an universal donor material. This would have a major impact because the generation of donor-specific MSCs is time-consuming, costly, and often impractical if the clinical status of a patient is urgent.
In the present study, the investigators will prospectively evaluate the efficacy and safety of ex-vivo-expanded BM-derived MSCs from third-party donors in treating patients with PGF after allo-HSCT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mesenchymal stem cellsBiological
Mesenchymal stem cells will be intravenously infused via a central venous catheter,at a dose of 1×10^6 cells/kg, over 15 min. The vital signs of all patients will be closely monitored during and for 24h after MSCs administration. If the NEU and PLT levels do not attain the completely response(CR)standards within 14d, a second course of MSCs treatment will be given.

| Mesenchymal stem cells | Experimental | Mesenchymal stem cells 1×10^6 cells/kg, intravenously Receives: Biological: Mesenchymal stem cells |
What is being measured
The primary outcome is the main question the study is designed to answer.
hematopoietic recovery
Hematopoietic reconstitution post-transplantation is defined as reconstitution of both neutrophil and platelet numbers. Neutrophil reconstitution is defined as occurring on the first 3 consecutive days with an neutrophil(NEU)>0.5×10^9/L, and platelet (PLT) reconstitution is defined as the first >20×10^9/L for 3 consecutive days.
Measured: 1 year
Secondary outcomes (1)
infections, primary underlying disease relapse and any toxic side effects of MSCs treatment
Infections will be mainly focused within the first 100 days after MSCs treatment. Toxic side effects of treatment includes acute toxicity and late side effects. Acute toxicity principally involves the heart,live and kidney. Late toxic side effects involves principally the development of secondary tumors and relapse of the primary disease.
Measured: 1 year

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 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.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ren Lin, MD (+86-020-61641613, lansinglinren@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
hematopoietic recovery (time frame: 1 year). 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 NCT01763086, 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 16 Jan 2013.
