Trial summary

Chemotherapy or targeted therapy are usually used to treat hematological pathologies. Despite of medical improvement, some of these pathologies present drug resistances, or high risk of relapse. Hematopoietic stem cell (HSC) transplantation remain the gold standard of consolidation, to maintain a durable response. Read more about this study

About this study

Official title: Biomarkers Impact Evaluation on the Post-transplant Immune Response After Allografting of Hematopoietic Stem Cells: MENTALO Study

Chemotherapy or targeted therapy are usually used to treat hematological pathologies. Despite of medical improvement, some of these pathologies present drug resistances, or high risk of relapse. Hematopoietic stem cell (HSC) transplantation remain the gold standard of consolidation, to maintain a durable response. In this situation, allograft with hematopoietic stem cells donor aims at producing Graft-versus-Tumor effect, by producing a new immune system, reproducing anti-tumoral immunity.

However, all hemopathies do not have the same sensibility. Nowadays, mechanisms underlying this phenomenon remain poorly understood.

Indeed, few data precisely document the expression of immunological checkpoints and other biomarkers in the context of allogeneic HSC transplantation, particularly their impact on post-transplant outcome.

Chemotherapy or targeted therapy are usually used to treat hematological pathologies. Despite of medical improvement, some of these pathologies present drug resistances, or high risk of relapse. Hematopoietic stem cell (HSC) transplantation remain the gold standard of consolidation, to maintain a durable response. In this situation, allograft with hematopoietic stem cells donor aims at producing Graft-versus-Tumor effect, by producing a new immune system, reproducing anti-tumoral immunity.

However, all hemopathies do not have the same sensibility. Nowadays, mechanisms underlying this phenomenon remain poorly understood.

Indeed, few data precisely document the expression of immunological checkpoints and other biomarkers in the context of allogeneic HSC transplantation, particularly their impact on post-transplant outcome. Therefore, we want to systematically study the expression profile of different biomarkers during allogeneic transplantation, in order to establish a correlation between these expression patterns and post-transplant outcome. Ultimately, this research will enable to (i) have tools to predict the post-transplant response and (ii) define whether a targeted therapy could be beneficial or be contraindicated for adequate patient management.

Patients will be selected for the study once they meet all the inclusion criteria. The study will be proposed to them during the pre-allogeneic consultation as part of their usual care. This study does not modify the treatment or the usual management of patients according to the current practice of pre- and post-transplant management. Clinically, it consists of building up a relevant biological collection.

What participants receive

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

  • Blood samplesOther

    A peripheral blood sample will be taken and will include 2 EDTA tubes of 5 mL, for a total volume of 10 mL:

    • Samples before the allograft,
    • Samples at different times post-allograft: 15 days, 30 days, 60 days, 90 days, 180 days, 360 days,
    • Samples in the event of the occurrence of concomitant events during the 12-month follow-up period: occurrence of acute Graft Versus Host Disease, chronic Graft Versus Host Disease, or relapse of the disease before the initiation of a new treatment.

Questions about this trial

What is this clinical trial studying?

A study testing Blood samples in people with Malignant Hemopathy, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.

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 3 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: looking for participants now, as of the sponsor's last update on 9 Apr 2025. 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 France. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jérôme Cornillon, MD (477917089 ext. +33, elisabeth.daguenet@chu-st-etienne.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Expression level of Programmed death-ligand (PD) plasmatic biomarkers (time frame: 12 months). The study lists 4 primary outcomes in all. 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 9 Apr 2025.
