What the trial is, and whether it could suit you
Mepolizumab is a biologic agent already approved for severe asthma. Recently, there is increasing evidence concerning the benefit of anti-IL5 treatments upon patients with nasal polyposis with or without severe asthma.
The novelty of this project is that no biologic agent has yet been fully investigated to identify any biomarkers of response for patients with nasal polyps with or without asthma including sinonasal tissue remodeling a key element in the resultant histopathological changes of the inflammation. The investigation of airway remodeling of various locations (nose and bronchus) under mepolizumab treatment will be our primary objective on the long-term basis of 156 weeks of treatment.
Endobronchial and nasal biopsies will be performed as routine care for tissue evauation and disease investigation for every patient.
Besides, the united airways will provide better guidance for m
