Clinical Trial Summary

Prospective study to evaluate the relevance of CALR allele burden monitoring as a molecular marker of disease progression.

Clinical Trial Description

A first local study on 45 patients showed the prognostic impact of CALR mutation quantification in follow-up, independently of the European LeukemiaNet (ELN) prognostic score validated in this group of patients. This study aims to evaluate a multicenter cohort of 260 patients, including all types of CALR-mutated MPNs and several follow-up samples, to model the temporal evolution of CALR allele burden. Blood of MPN patients will be collected, at the time of diagnosis and for 3 years (max 1 sample/year), for the quantification of the CALR allele burden. During follow-up, a clinicobiological score to define the progression or not of the disease for each patient will be evaluated in Essential Thrombocythemia (ET) and MyeloFibrosis (MF). ;
