About this study

Official title: Search of Circulating Endothelial Cells of Donor Origin After Allogeneic Hematopoietic Stem Cell Transplantation: Evaluation for Potential Clinically Relevant Implications in the Context of Graft-Versus-Host Disease

We believe that CEC, besides coming from cells shedding from patient vasculature, could partly belong to donor, originating from the cellular graft.

Read the detailed description

In consideration of the fact that the vascular endothelium has been shown to be a target of GvHD in early stage and that the count of CEC represent a marker of endothelial damage, we want to correlate the presence of donor CEC at engraftment with a putative protective function against GVHD manifestations. We will enroll patients affected by hematologic disorders undergoing allo-HSCT. At time of engraftment and at + 3 months after allo-HSCT, CEC identified and counted by means of the CellSearch system, will be recovered from the counting cartridge and further sorted at the single cell level. STR profile of each single CEC recovered will be performed in order to define host versus donor origin of each CEC analysed.

Through the conduct of this study, we expect to upfront identify patients who will or will not manifest GvHD. This result will allow definitely different clinical approaches: stringent monitoring and early therapeutic intervention, before refractory disease's development, in the formers, while, sparing unnecessarily expensive testing or heavier treatment in the latters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • D-CEC countingDiagnostic test

    By means of preliminary bulk separation step with the CellSearch system, single CEC will be sorted

What is being measured

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

  1. Presence of D-CEC at time of engraftment in patients undergoing allo-HSCT

    Single CEC will be isolated and STR profile determined

    Measured: Within 30 days from allo-HSCT

  2. Correlate presence/absence of D-CEC with GVHD manifestations

    D-CEC presence will be correlated with GVHD onset

    Measured: day +100 post allo-HSCT

Secondary outcomes (1)

  1. Presence of donor CEC embedded in the endothelial layer of patients microvasculature at late timepoint after allo-HSCT

    CISH analysis will be performed on tissue biopsies at 3 months post-transplant

    Measured: day +100 post allo-HSCT

Questions about this trial

What is this clinical trial studying?

An observational study of Graft Versus Host Disease, Acute and Endothelial Dysfunction, run by Azienda Socio Sanitaria Territoriale degli Spedali Civili di Brescia at 1 site in Italy.

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 4 inclusion and 1 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 8 Jul 2020. 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 Italy. 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?

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?

Presence of D-CEC at time of engraftment in patients undergoing allo-HSCT (time frame: Within 30 days from allo-HSCT). The study lists 2 primary outcomes in all. 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 NCT04038827, which also lists 13 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 8 Jul 2020.
