Identification by Cytometry by Mass of Predictive Immunological Profiles of Answer to Treatmentby Biotherapics for Patients With Crohn's Disease (PICTURE)

NCT03712826 NA WITHDRAWN

Crohn disease is an inflammatory chronic disease of the bowel the complex physiopathology of which brings in immunological, genetic and environmental factors. At present, the appeal to biotherapics anti-TNFa (infliximab and adalimumab) or anti-IL-12/23 (ustekinumab) in MC represents a major therapeutic progress at the origin of a significant improvement of the symptoms, the healing of the intestinal hurts and the quality of life. Considering the new immunological targets of these biotherapics, the investigators put the hypothesis that an immunological profile (impulsive person and\\or tissular) specific of the patients with one MC is associated with the answer to biotherapics. So, before beginning the treatment the patients expressing strongly the pro-inflammatory cytokine TNFa, would more may be answering machines in anti-TNFa and those with whom the immunological profile is very marked towards the way Th1/Th17 would more may answer favorably the ustekinumab. The identification of immunological profiles capable of predicting before treatment the answer under biotherapics could establish in MC but also in other inflammatory diseases a major step forward to guide the coverage.
