Benralizumab Airway Remodeling Study in Severe Eosinophilic Asthmatics

Running, not enrolling · Phase 4 · Has a placebo group

Conditions studied: Asthma

In brief

The purpose of the study is to evaluate effect of benralizumab on structural and lung function changes in severe eosinophilic asthmatics. Changes will be assessed over 48 week treatment period in patients with persistent symptoms despite standard therapy of inhaled corticosteroids (ICS) plus long acting B2-agonist (LABA) with or without additional controller medication. Patients who complete treatment will enter 4 weeks follow-up period.
