The Oral cGVHD as a Predictive Factor of Graft Versus Leukaemia Effect in Patients Who Received an Allograft

December 5, 2025 updated by: Centre Hospitalier Universitaire de Nice

"Oral Chronic Graft-Versus-Host Disease (cGVHD) as a Potential Clinical Marker of the Graft-Versus-Leukemia (GVL) Effect in Allogeneic Hematopoietic Stem Cell Transplantation:Prospective Single-Center Study"

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the standard treatment for many malignant blood disorders. Its effectiveness is based on the graft-versus-leukemia (GVL) effect, which is intrinsically linked to the occurrence of graft-versus-host disease (GVHD). While GVHD reflects favorable alloreactivity, its severe forms increase While GVHD reflects favorable allograft reactivity, its severe forms increase non-relapse mortality (NRM) and impair quality of life. Currently, there is no simple clinical marker that can predict or monitor the efficacy of the GVL effect. The investigators therefore hypothesized that chronic oral GVHD, a common and easily identifiable manifestation, could reflect beneficial alloreactivity, reflecting a balance between GVL effect and toxicity. The investigators conducted a prospective, observational, single-center study including patients transplanted at the Nice University Hospital between October 2023 and May 2025, followed by a standardized stomatological protocol before and after transplantation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall survival
Time Frame: 3 months, 6 months, 1 years and 1,5 years
Overall Survival (OS) is defined as the time, measured in months, from the date of study entry (or randomization, depending on protocol specifications) to death from any cause. Participants who are alive at the time of the last known follow-up are censored at that date.
3 months, 6 months, 1 years and 1,5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease free survival,
Time Frame: 3 months, 6 months, 1 years and 1,5 years
Disease-Free Survival (DFS) is defined as the time, measured in months, from the date of curative-intent treatment (or randomization, according to protocol specifications) to the first documented recurrence of the disease or death from any cause, whichever occurs first. Participants who remain alive and free of disease at the time of the last known follow-up are censored at that date.
3 months, 6 months, 1 years and 1,5 years
Non relapse mortality
Time Frame: 3 months, 6 months, 1 years and 1,5 years
Non-Relapse Mortality (NRM) is defined as the time, measured in months, from the date of allogeneic transplantation (or study entry, depending on protocol specifications) to death without prior disease relapse or progression. Deaths occurring after documented relapse/progression are not counted as NRM events. Participants who are alive without relapse at last follow-up are censored at that date.
3 months, 6 months, 1 years and 1,5 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2023

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
