6 February 2026 - GSK today announced the European Commission has approved Nucala (mepolizumab), a monoclonal antibody targeting interleukin-5 , in adults as an add-on maintenance treatment for uncontrolled COPD characterised by raised blood eosinophils on a combination of an inhaled corticosteroid, a long-acting beta2-agonist, and a long-acting muscarinic antagonist.
The approval was based on data from the positive MATINEE Phase 3 trial in which mepolizumab showed a clinically meaningful and statistically significant reduction in the annualised rate of moderate/severe exacerbations versus placebo plus standard of care in a wide spectrum of COPD patients with an eosinophilic phenotype.
