Mepolizumab in Chronic Obstructive Pulmonary Diseases (COPD) With Eosinophilic Bronchitis

It is thus likely that a specific treatment such as anti-IL5 directed against eosinophils would be superior to the current standard treatment in decreasing sputum eosinophil counts and exacerbations and decrease structural changes (remodelling) in patients with COPD who continue to have eosinophils in their airway and whose airway disease has an eosinophil-driven component as evidenced by persistent airway eosinophilia.
