a prospective observational study for evaluating cgvhd

Conditions: Chronic Graft-Versus-Host Disease

Summary: prospective, observational, multicentre, spontaneous, non-interventional study this study will evaluate all consecutive patients who develop chronic graft-versus-host disease, reported by the italian gitmo centers according to a standardized web platform for real-time, onsite data collection. the platform for data collection will be based on a software prototype developed by the clinica di ematologia di ancona transplant center for the management of patients with chronic graft-versus-host disease. this software has been integrated with algorithms that automatically determine: severity of chronic graft-versus-host disease and overall response according to the 2015 nih consensus criteria.

chronic graft-versus-host disease represents the first cause of transplant-related mortality and reduced quality of life after transplant (hsct). the epidemiology of chronic graft-versus-host disease is largely unknown; moreover, diagnosis of chronic graft-versus-host disease can be easily missed because its onset is often late in the post-transplant period, requires specific follow up, and general practitioners are usually not familiar with this entity. successful treatment of chronic graft-versus-host disease represents an unmet clinical need in the field of allogeneic transplantation. steroids are standard treatment, but up to 60% of the patients will require second-line treatment but there is no standard second-line treatment for chronic graft-versus-host disease steroid refractory. to help standardise the management chronic graft-versus-host disease, the nih consortium proposed consensus definitions for diagnosis, scoring and response criteria in 2006 revised in 2015 which offers a shared framework to study this rare disease. these criteria are not yet validated and thus not suitable for clinical trials. this study is prospective, observational, multicentre, spontaneous, non-interventional study that will evaluate all consecutive patients who develop chronic graft-versus-host disease, reported by the italian gitmo centers according to a standardized web platform for real-time, on-site data collection. the platform for data collection will be based on a software prototype developed by the ancona transplant center for the management of patients with chronic graft-versus-host disease. this software has been integrated with algorithms that automatically determine: severity of chronic graft-versus-host disease and overall response by the 2015 nih consensus criteria. historical controls to compare chronic graft-versus-host disease incidence, toxicities, response rate and hard outcomes will be used. the aim of this project is to evaluate prospectively the long-term effectiveness of different therapies by the hard outcome "failure free survival" commonly considered the most reliable one. the failure free survival is the result of a number of factors that influence the treatment failure and has been shown a reliable predictor of long-term survival. main cause of failure is the change in immunosuppressive treatment although recurrent disease, treatment toxicity and mortality from chronic graft-versus-host disease (or other infectious complications) also contribute to failure free survival. second, we aim to evaluate the prognostic ability of the latest nih response criteria to predict main hard survival outcomes and to assess their suitability as a tool for decision-making that ultimately leads to treatment changes. finally, we aim to evaluate the feasibility of the use of an electronic tool for data collection in daily clinical practice.
