Mepolizumab for eosinophilic chronic obstructive pulmonary disease
BACKGROUNDPatients with chronic obstructive pulmonary disease (COPD) with an eosinophilic phenotype may benefit from treatment with mepolizumab, a monoclonal antibody directed against interleukin-5.METHODSWe performed two phase 3, randomized, placebo-controlled, double-blind, parallel-group trials comparing mepolizumab (100 mg in METREX, 100 or 300 mg in METREO) with placebo, given as a subcutaneous injection every 4 weeks for 52 weeks in patients with COPD who had a history of moderate or severe exacerbations while taking inhaled glucocorticoid-based triple maintenance therapy. In METREX, unselected patients in the modified intention-to-treat population with an eosinophilic phenotype were …
Late Breaking Abstract - Dose-ranging study of mepolizumab in eosinophilic COPD
Background: Patients with eosinophilic COPD & frequent exacerbations may benefit from mepolizumab (MEP) treatment. Objective: Assess efficacy & safety of 2 MEP doses vs placebo (PBO) in COPD with blood eosinophils ≥150 cells/µL [screening] or ≥300 cells/µL [prior yr], history of ≥2 moderate/≥1 severe exacerbations & ICS+≥2 bronchodilator maintenance therapies (ICS+MT). Methods: Phase III, randomised, PBO-controlled, double-blind, parallel-group trial (METREO); patients received SC MEP 100mg, MEP 300mg or PBO plus ICS+MT, every 4 wks for 52 wks. Primary endpoint: rate/yr of moderate (systemic corticosteroids/antibiotics)/severe(hospitalisation or death) exacerbations. Secondary endpoints inc…
