    Outcomes

    Primary Outcome Measures

    The proportion of subjects in remission [OGC 4.0]
    The proportion of subjects in remission (oral glucocorticoid [OGC] 4.0) at Week 28 of the study treatment period. Definition of remission (OGC 4.0): BVAS of 0 AND OGC dose of prednisolone/prednisone ≤4 mg/day

    Secondary Outcome Measures

    The proportion of subjects in remission [OGC 7.5]
    The proportion of subjects in remission (OGC 7.5) at Week 28 of the study treatment period Definition of remission (OGC 7.5): BVAS of 0 AND OGC dose of prednisolone/prednisone ≤7.5 mg/day
    Time to first relapse of EGPA
    Relapse of EGPA will be defined as active disease since the last visit after remission (OGC 4.0) was achieved, characterized by: Active vasculitis (BVAS of >0); OR Signs and/or symptoms of active asthma with a corresponding worsening in answers on the 6-item Asthma Control Questionnaire (compared with the most recent previous results); OR Active nasal and/or sinus disease (attributable to EGPA) with a corresponding worsening in at least 1 of the answers on the sinonasal symptom questionnaire (compared with the most recent previous assessment).
    Time to first worsening of EGPA
    Worsening of EGPA will be defined as worsening of active disease since the last visit, characterized by: Active vasculitis (BVAS >0) and the score greater than the previous visit; OR Signs and/or symptoms of active asthma with a corresponding worsening in answers on the 6-item Asthma Control Questionnaire (compared to the most recent previous score); OR Active nasal and/or sinus disease (attributable to EGPA) with a corresponding worsening in at least 1 of the answers on the sinonasal symptom questionnaire (compared to the most recent previous assessment).

    5. Study Description

    Brief Summary
    This study will enroll male and female subjects who are 18 years of age or older with Eosinophilic Granulomatosis With Polyangiitis.
    Detailed Description
    The purpose of this randomized, double-blind study is to investigate the efficacy and safety of NS229 compared with placebo over a 28-week study treatment period in subjects with Eosinophilic Granulomatosis with Polyangiitis (EGPA) receiving background corticosteroid therapy with or without mepolizumab therapy. During the treatment period corticosteroid dose will be tapered. The key outcomes in the study focus on evaluation of clinical remission, defined as Birmingham Vasculitis Activity Score (BVAS)=0 with a corticosteroid dose of <=4 mg/day prednisolone/prednisone.
