ListOutcomeTime frameDescription
PrimaryNumber of Subjects Who Achieved Main Remission at Both Weeks 36 and 48Week 36 and Week 48Percentage of patients with relapsing or refractory EGPA, achieving remission, defined as BVAS = 0 and OCS dose ≤ 4 mg/day (main remission definition) at both Weeks 36 and 48.
PrimarySupportive Endpoint: Proportion of Subjects Who Achieved Supportive Remission at Both Weeks 36 and 48Week 36 and Week 48
Supportive endpoint: Proportion of patients with relapsing or refractory EGPA, achieving remission, defined as BVAS = 0 and OCS dose ≤ 7.5 mg/day (supportive remission definition) at both Weeks 36 and 48.
SecondaryTotal Accrued Duration of Remission During DB Treatment Periodfrom baseline to end of DB period, 52 Weeks.Total accrued duration of remission for the following categories: 0 week, \> 0 to \< 12 week, 12 to \< 24 week, 24 to \< 36 week, ≥ 36 week.
SecondaryTotal Accrued Duration of Sustained Remission During DB Treatment Periodfrom baseline to end of DB period, 52 WeeksTotal accrued duration of sustained remission for the following categories: 0 week, \> 0 to \< 12 week, 12 to \< 24 week, 24 to \< 36 week, ≥ 36 week.
SecondaryTime From Randomization to First Eosinophilic Granulomatosis With Polyangiitis (EGPA) Relapsefrom baseline to end of DB period, 52 Weeks
Time from randomization to first Eosinophilic Granulomatosis with Polyangiitis (EGPA) relapse, where relapse is defined as any of the following: * Active vasculitis (BVAS \> 0); OR * Active asthma symptoms and/or signs with a corresponding worsening in ACQ-6 score; OR * Active nasal and/or sinus disease, with a corresponding worsening in at least one of the sino-nasal symptom questions; warranting any of the following: * An increased dose of OCS therapy to \> 4 mg/day prednisolone total daily dose; OR * An increased dose or addition of immunosuppressive therapy; OR * Hospitalization related to EGPA worsening Calculated using the Kaplan-Meier technique.
SecondaryAnnualized Eosinophilic Granulomatosis With Polyangiitis (EGPA) Relapse Ratefrom baseline to end of DB period, 52 Weeks
Annualized Eosinophilic Granulomatosis with Polyangiitis (EGPA) relapse rate through end of DB treatment period. The estimate of annualized relapse rate (relapses per year) and the corresponding 95% CIs were calculated using a negative binomial model. The response variable in the model is the number of relapses experienced by a subject up to Week 52. The logarithm of the subject's corresponding follow-up time up to Week 52 was used as an offset variable to adjust for subjects having different follow-up times during which the events occur. The covariates in the model include treatment arm, baseline dose of prednisone, baseline BVAS and region.
SecondaryAverage Daily Dose of Prednisolone/Prednisone and Change From Baseline During Week 48 Through 52last 4 weeks of DB periodAverage daily dose of prednisolone/prednisone and change from baseline during Week 48 through 52, or last 28 days prior to last double-blind assessment for those that withdrew
SecondaryProportion of Patients With Average Daily Dose of Prednisolone/Prednisone During Week 48 Through 52last 4 weeks of DB periodProportion of patients with average daily dose of prednisolone/prednisone during Week 48 through 52 in each category: 0 mg; \>0 to ≤ 4 mg; \> 4 to ≤ 7.5 mg and \> 7.5 mg
SecondaryPercentage Reduction From Baseline in Average Daily Dose of Prednisolone/Prednisone During Week 48 Through 52last 4 weeks of DB period
Percentage reduction from baseline in average daily dose of prednisolone/prednisone during Week 48 through 52 in each category: no reduction or withdrawal from treatment; \< 25% reduction; 25 to \< 50% reduction; 50 to \<75% reduction; 75 to \< 100% reduction; 100% reduction.
SecondaryProportion of Subjects With Reduction From Baseline in Average Daily Dose of Prednisolone/Prednisone During Week 48 Through 52last 4 weeks of DB period
Proportion of subjects with reduction from baseline in average daily dose of prednisolone/prednisone during Week 48 through 52 in each category: \>= 50% reduction; 100% reduction; OCS dose \<= 4 mg/day.
