Clinical Trial Summary

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as the Churg-Strauss syndrome, is a systemic necrotizing vasculitis that affects small and medium sized blood vessels. NUCALA® (mepolizumab 300 milligrams [mg], subcutaneous administration) was approved in Japan in 2018 for the treatment of EGPA in adult participants. This is a single-arm, multi-center, prospective, non-interventional study that aims to assess long-term (2 to 4 years) real-world safety and effectiveness of NUCALA. Approximately 120 participants who completed the NUCALA Post Marketing Surveillance (PMS) study (National Clinical Trial [NCT]03557060) will be enrolled in the study. NUCALA is a registered trademark of GlaxoSmithKline (GSK) group of companies.
