Trial summary

Allogeneic hematopoietic cell transplantation offers high cure rates for patients with hematological and oncological diseases. Graft-versus-host disease (attack of donor's white blood cells on patient's tissues) is a serious complication also affecting the patient's immune system. Read more about this study

About this study

Official title: Prospective Phase II Study for Assessment of Regulatory Immune Cell Populations After Allogeneic Hematopoietic Stem Cell Transplantation and Immunomodulatory Consequences of Chronic Graft-Versus-Host Disease and Therapy

Allogeneic hematopoietic cell transplantation offers high cure rates for patients with hematological and oncological diseases. Graft-versus-host disease (attack of donor's white blood cells on patient's tissues) is a serious complication also affecting the patient's immune system. Therefore, patients in the early phase after allogeneic cell transplantation are at high risk for severe infectious complications. So far, no predictive biomarkers for the development of the chronic form of graft-versus-host disease are available. By analysing serially immune cell populations of the peripheral blood we will investigate whether certain subsets of cells are associated with development of chronic graft-versus-host disease. In addition, the patients' immune regeneration will be evaluated by serial analyses of peripheral blood immune cell populations 3 months to 2 years after allogeneic cell transplantation.

What is being measured

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

  1. Correlation of perturbed B cell homeostasis with chronic graft-versus-host disease activity of immune system

    Measured: October 2007 until December 2010

Secondary outcomes (5)
  1. Difference of time-dependent pattern of immune reconstitution after allogeneic cell transplantation between patients with and without chronic graft-versus-host disease

    Measured: October 2010 until December 2010

  2. Compare number of clinically defined bacterial, viral and fungal infectious episodes between patients with and without chronic graft-versus-host disease

    Measured: October 2007 until December 2010

  3. Compare the number of circulating T, DC, NK subsets in patients with and without chronic GVHD to identify their respective role in development and prolongation of chronic GVHD

    Measured: October 2007 until December 2010

  4. Investigate the impact of different immunosuppressive/immunomodulatory treatments for chronic GVHD on various immune cell populations

    Measured: October 2007 until December 2010

  5. Assess the chimerism of antigen-presenting cells in circulation and tissue specimens and correlate it with occurrence of chronic GVHD

    Measured: October 2007 until December 2010

Questions about this trial

What is this clinical trial studying?

An observational study of Allogeneic Hematopoietic Cell Transplant Recipients, run by Medical University of Vienna at 2 sites in 2 countries.

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 6 inclusion and 6 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 7 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Austria, Czechia. 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.

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 Hildegard T Greinix, Professor (+43140400 ext. 4457, hildegard.greinix@meduniwien.ac.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation of perturbed B cell homeostasis with chronic graft-versus-host disease activity of immune system (time frame: October 2007 until December 2010). 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 7 Jan 2008.
