About this study

Official title: Randomized Trial of GVHD Prophylasxis With Post-transplantation Cyclophocphomide (PTCy) or Thymoglobulin in Unrelated SCT Recepients With Chronic Myeloproliferative Neoplasms and Myelodisplatic Syndrome

Purpose There is a growing evidence of high efficacy of post-transplantation cyclophocphomide (PTCy)-based GVHD prophylaxis in haploidentical and matched related and unrelated bone marrow transplantation. There is limitted, but growing data on safety and efficacy of this prophylaxis in unrelated and peripheral blood stem cell transplantations. Use of PTCy in chronic myeloproliferative neoplasms and myelodisplatic syndrome is of particular interest. On the one hand, PTCy could reduce the incidence of chronic GVHD and long-term bormidity. On the other hand, there is a concern, that PTCy can increase the incidence of graft failures in this group of patients. Currently published data indicate that low-dose Thymoglobulin-based prophylaxis is the most promissing compatitor in terms of acute and chronic GVHD control. So there is a rationale to randomize Thymoglobulin and PTCy as GVHD prophilaxis. Pre-transplant assesment of moratlity (PAM)-index will be used as the strata for randomization, as it is the paramter that takes into account the most important factors effecting survival. The conditioning regimen and the other two components of GVHD prophylaxis (mycophenolate mofetil and tacrolimus) will be identical in the two arms of the study.

What is being measured

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

  1. Incidence of primary graft failure

    Measured: 60 days

Secondary outcomes (8)
  1. Incidence of acute GVHD, grades II-IV

    Measured: 365 days

  2. Incidence of chronic GVHD, moderate and severe (NIH criteria)

    Measured: 365 days

  3. Non-relapse mortality analysis

    Measured: 365 days

  4. Event-free survival analysis

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Unrelated allogeneic stem cell transplantation, Busulfan and Fludarabine monophosphate in people with Leukemia, Chronic Myeloid and Myelodysplastic Syndromes, run by St. Petersburg State Pavlov Medical University at 1 site in Russia.

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 8 inclusion and 10 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: stopped early, as of the sponsor's last update on 5 Apr 2019. 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 Russia. 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?

The study was stopped early (reason given: Poor recruitment). Results are not available in the source record.

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?

Incidence of primary graft failure (time frame: 60 days). 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 5 Apr 2019.
