Benralizumab Effectiveness in the LONG-term Real-life Setting in EGPA: The BELONG-EGPA Study
This is a multicenter, retro-prospective observational study evaluating the effectiveness and safety of benralizumab in adult patients with eosinophilic granulomatosis with polyangiitis (EGPA) in a real-world setting.
The study will include patients treated with benralizumab 30 mg every 4 weeks at EGPA referral centers participating in the European EGPA Study Group.
Clinical, laboratory, lung function, treatment, relapse, and safety data will be collected from medical charts at baseline and during follow-up up to 24 months.

Detaillierte Beschreibung
BELONG-EGPA is a multicenter, retro-prospective observational study conducted within centers belonging to the European EGPA Study Group. The study is designed to evaluate the long-term real-world effectiveness and safety of benralizumab in adult patients with eosinophilic granulomatosis with polyangiitis (EGPA).
The study population will include adult patients with EGPA who meet the 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for EGPA or the criteria proposed in the MIRRA trial, and who receive benralizumab 30 mg every 4 weeks. Only patients with at least 3 months of available follow-up after starting benralizumab will be included.
Demographic, clinical, biological, lung function, and treatment-related data will be collected from medical charts through a standardized electronic case report form. Data will be collected at the start of benralizumab treatment and at 3, 6, 12, and 24 months of follow-up.
The primary effectiveness outcomes include achievement of complete response and partial response, changes in lung function measured by pre-bronchodilator FEV1, and disease relapses. Complete response is defined as no disease activity, with Birmingham Vasculitis Activity Score equal to 0, and an oral corticosteroid dose of 4.0 mg/day or less of prednisone, prednisolone, or equivalent. Partial response is defined as no disease activity with an oral corticosteroid dose greater than 4.0 mg/day.
Secondary outcomes include treatment persistence, oral corticosteroid tapering and discontinuation, effectiveness and safety in first-line patients compared with patients previously exposed to mepolizumab, outcomes after benralizumab dosage switching, and adverse events and serious adverse events during treatment.
Additional outcomes include changes in organ manifestations, discontinuation of disease-modifying antirheumatic drugs, changes in ANCA status, and variation in eosinophil count. All data will be anonymized and stored in a centralized database.

Patients with EGPA treated with benralizumab
Adult patients with eosinophilic granulomatosis with polyangiitis (EGPA) receiving benralizumab 30 mg every 4 weeks in a real-world setting.
Patients may be newly diagnosed or have relapsing or refractory EGPA and must have at least 3 months of available follow-up after starting benralizumab.
|
Benralizumab administered at a dose of 30 mg every 4 weeks in adult patients with eosinophilic granulomatosis with polyangiitis (EGPA) in a real-world setting.
Patients may receive benralizumab as first-line biologic therapy or after previous exposure to mepolizumab.
Treatment use, persistence, dosage changes, effectiveness outcomes, and safety events will be assessed during follow-up.
