About this study

Official title: G-CSF Mobilized Peripheral Blood Stem Cell Combined With Mesenchymal Stem Cells for Treatment of Poor Graft Function After Allogeneic Hematopoietic Stem Cell Transplant

The purpose of this study is to evaluate the utility of treating patients experiencing poor graft function after allogeneic hematopoietic stem cell transplantation with Granulocyte Colony-Stimulating Factor (G-CSF) mobilized peripheral stem cell combined (PBSC) 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) is the only cure for many hematologic diseases. However, poor graft function (PGF) is an important complication after allo-HSCT that occurs in 5-27% of patients, and is associated with considerable 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 second transplantation, but these methods are associated with dismal effect or even a significant risk of graft-versus-host disease (GVHD).

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 include improving hematopoietic engraftment, preventing and treating graft-versus-host disease after allo-HSCT and so on. Some studies have shown that MSCs combined with PBSC or cord blood could be useful to improve engraftment after HSCT. Several reports suggested MSCs might be effective in the treatment of PGF.

However, the efficacy of MSCs as single-drug treatment for PGF is unsatisfactory in our previous study. Therefore, in the present study, G-CSF mobilized PBSC will be used combined with MSCs in the 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.

Study groups in NCT02083718
Study groupRoleWhat they receive
PBSC & MSCsExperimentalPBSC will be intravenously infused at a dose of 2×10^8/kg. MSCs will be intravenously infused at a dose of 1×10^6 cells/kg once per week. The vital signs of all patients will be closely monitored during and for 24h after administration.If the NEU and PLT levels do not attain the completely response(CR)standards within 28d, a second course of the same treatment will be given.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants with 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)
  1. Number of Participants with Serious and Non-Serious Adverse Events

    Adverse Events include infections, GVHD, primary underlying disease relapse and any other side effects. Infections will be mainly focused within the first 100 days after treatment. 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: up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PBSC and MSCs in people with Stem Cell Transplantation, Hematopoietic and Poor Graft Function, 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 3 inclusion and 2 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 11 Mar 2014. 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 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?

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?

Percentage of Participants with 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 NCT02083718, 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 11 Mar 2014.
