Clinical Details
Official title: Diagnostic and Prognostic Biomarkers for Acute Graft-versus-host Disease: a Prospective Single Centre Biological Study
Study design: Observational Model: Cohort, Time Perspective: Prospective
Primary outcome: Number of patients with an Acute Graft-versus-Host diseaseNumber of patients with an Acute Graft-versus-Host disease refractory to steroids
Detailed description:
Description of the project: The main objective of this prospective biological single center
study (non interventional) is to identify non invasive biomarkers able to diagnose acute
GVHD and/or predict outcome of patients with acute GVHD. The primary objective of the study
is double: (1): to evaluate markers as diagnostic markers of GVHD (2): to evaluate the
potential of the markers as risk factor for steroid-refractory acute GVHD occurrence.
Secondary objectives are: - to evaluate the markers as risk factors for GVHD -to evaluate the
potential of these markers as prognostic factors of 6-month non-relapse mortality in
patients with acute GVHD-to evaluate the additional value of the biomarkers to predict GVHD
or steroid-refractory GVHD as compared to other known and routinely used risk factors
(clinical grading system, performance status, albuminemia...). Stools and blood will be on
day 7, 14, 21, 28 after transplantation and the first day of digestive GVHD. Management of
patients will not differ from the usual care. Fecal calprotectin and alpha 1 anti-trypsin,
plasmatic RER3a, IL-8, Elafin, TNFaR1, IL-2R alpha, HGF will be measured at each points by
ELISA tests. 315 patients would be sufficient to estimate the area under the ROC curve with
a half-width of the 99% confidence interval of 0. 05, assuming 60% of patients would develop
acute GVHD, and normally distributed markers. The diagnosis and prognosis values will be
analyzed separately.
Expected results: If some biomarkers are found significantly associated with diagnosis or
prognosis of acute GVHD, they will be compared with the current clinical, biological and
histological markers. Indeed, these markers have a clinical potential impact only if they
give similar or better information than routine currently available markers, ie: clinical
GVHD grading system, performance status, gut endoscopy and histology. The non-invasivity of
these biomarkers should also be taken into account (in comparison to histology).
Identification of diagnostic markers will avoid useless treatment with high dose
corticosteroids in patients without GVHD Identification of prognostic markers will comfort
the decision of a second-line treatment sooner than usually, ie: at GVHD onset. Indeed, the
onset of a second-line treatment after a steroid-refractory GVHD varies from 3 to 21 days
depending on clinical evolution of patients. If some prognostic markers are available at
diagnosis, delay in second-line treatment can be shortened and the patient can consequently
have an increased chance to response to an early treatment.
Identification of prognostic markers will also guide the corticosteroids decrease in
patients with good prognosis GVHD
