About this study
Mesenchymal stem cells (MSCs) have been used in the treatment and prevention of graft-versus host disease (GVHD). In this study the investigators aim to present the efficacy of mesenchymal stem cells in graft versus host disease prophylaxis and effect of engraftment in haploidentical recipients. Forty patients aged older than 18 who have indications for haploidentical hematopoietic stem cell transplantation will be included to the study. MSCs will be isolated from donor bone marrows and infused to the patient after conditioning regimen on day +6. If the haploidentical transplantation results improve with MSCs treatment it would be possible to ameliorate the problem of HLA-matched donor paucity in Turkey and prefer haploidentical donors.
Read the detailed description
Mesenchymal stem cells (MSCs) have been utilized in the treatment and prevention of graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (alloSCT). However, studies on MSC use in alloSCT from haploidentical donors (haploSCT) have been limited.
In this study, the investigators aim 1) to evaluate MSCs' efficacy in GVHD prophylaxis and effect on engraftment of the haploidentical graft, 2) to improve the success rate of haploSCT by further decreasing GVHD incidence and graft failure rate. With higher haploSCT success rates, haploidentical donors would be important alternative graft sources in patients without HLA-matched donors.
Forty patients who present to Ankara University, School of Medicine, Division of Hematology with hematological malignancies and have indications for haploSCT will be included in the study after informed consent is obtained. MSCs will be procured and isolated from donor bone marrows. MSCs will be isolated, cultured, and stored in the good manufacturing practice (GMP) laboratory in Ankara University Stem Cell Institute. Donor bone marrow will be harvested, four to six weeks prior to transplantation, for MSC isolation and culture. Patients will receive either an ablative or non-ablative induction regimen based on their age, diagnosis, and the disease status at the time of transplantation. Donor bone marrow will be harvested a second time on the day of transplantation and the procured bone marrow graft will be infused to the patient the same day. GVHD prophylaxis will include post-transplantation cyclophosphamide (Cy) on days +3 and +4 (50 mg/kg/day), tacrolimus, and mycophenolate mofetil. Stored MSCs will be infused to the patient on day +6. The endpoints include graft failure rate, GVHD incidence, transplant-related mortality, disease-free survival, and overall survival.
The investigators aim to evaluate the utility of MSCs in improving haploSCT results and to enhance the reliability and success of haploSCT. Successful transplants from haploidentical donors would ameliorate the problem of matched donor paucity in countries with a limited number of hematopoietic stem cell donors, such as Turkey, and would establish haploidentical donors an alternative donor source for patients without matched donors in Turkey. As haploidentical donors may be parents or children, rapid and easy access to donors would decrease wait times for alloSCT. Moreover, national current account deficit may be reduced through using grafts obtained from haploidentical donors residing in Turkey instead of grafts from foreign stem cell/umbilical cord banks.
In this project, the investigators seek to develop clinical therapy applications in concordant with the ambition of "renewal and repair of human cells, tissues, and organs through cellular therapy and cellular products" that is included in the The Scientific and Technological Research Council of Turkey 1003 Call for Projects.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing mesenchymal stem cells and cyclophosphamide administration in people with Hematopoietic Stem Cell Transplantation, run by Ankara University at 1 site in Turkey (Türkiye).
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: finished, as of the sponsor's last update on 10 Jan 2018. 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 Turkey (Türkiye). 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Effect of mesenchymal stem cells on overall survival in haploidentical stem cell transplantation (time frame: 36 months). 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 10 Jan 2018.
