Mepolizumab for eosinophilic asthma


Results from two small, randomized, double-blind studies showed that monthly I.V. infusions of mepolizumab (Bosatria—GlaxoSmithKline) 750 mg reduced the frequency of severe asthma exacerbations and improved quality of life in patients with refractory eosinophilic asthma with a history of recurrent severe exacerbations (trial 1) and was associated with a significant reduction in prednisone requirements for patients who had asthma with sputum eosinophilia (trial 2).
