Airway Remodeling During Mepolizumab Treatment

NCT03797404 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 37

No results posted yet for this study

Summary

Chronic airway changes, such as smooth muscle hypertrophy/hyperplasia, reticular basement membrane (RBM) thickening, goblet cells hyperplasia characterize severe asthma. Chronic inflammation, and especially eosinophilia and T2 cytokines are involved in these structural changes. The aim of this prospective observational study is to assess airway changes, assessed by bronchial biopsies before treatment, then after 6 months and 12 months, induced by mepolizumab in 40 severe asthma patients who will receive the treatment as part of their standard care. Changes in RBM thickening, in airway smooth muscle (ASM) area, in the number of PGP9 sections will be assessed on bronchial biopsies after 6 months and 12 months of mepolizumab treatment. Bronchoalveolar lavage (BAL) levels of inflammatory and remodeling mediators and of extra-cellular matrix (ECM) components will be measured after 6 months and 12 months of mepolizumab treatment. Relationship between clinical response to mepolizumab and remodeling changes after 6 months and 12 months will be assessed.
