Title: A Multi-centre, Open-label, Long-term Safety Study of Mepolizumab in Asthmatic Subjects Who Participated in theMEA115588 or MEA115575 Trials
Brief Summary: This is a multi-centre, open-label long-term safety study of 100 milligram (mg) mepolizumab administered subcutaneously (SC) every 4 weeks for 12 months in addition to standard of care in subjects who have severe, refractory asthma and a history of eosinophilic inflammation. Subjects who completed either MEA115588 or MEA115575 will be offered the opportunity to consent for this study.
