Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 6 to under 18 years with eosinophilic granulomatosis with polyangiitis who are stable on corticosteroid therapy.

Probably not a fit

Patients with current malignancies, history of anaphylaxis to biologics, or significant pre-existing health conditions may not benefit from this study.

What this trial studies

This open-label, multicenter trial evaluates the safety, pharmacokinetics, pharmacodynamics, efficacy, and immunogenicity of benralizumab administered subcutaneously every four weeks in children aged 6 to under 18 with eosinophilic granulomatosis with polyangiitis (EGPA). The study consists of a screening period, a 52-week treatment period, and an optional extension period for continued treatment. Participants will receive benralizumab during the treatment phase, with the possibility of extending their participation for an additional year. The trial aims to gather comprehensive data on the drug's effects in this pediatric population.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of eosinophilic diseases in children, leading to better health outcomes.

How similar studies have gone: Other studies have shown promise with similar biologic therapies in treating eosinophilic diseases, suggesting potential for success in this approach.

EGPA Cohort:

* Therapy with corticosteroids: The prescribed dose of oral corticosteroids (OCS) (greater than \[\>\] 0.1 milligrams per kilogram per day (mg/kg/day), max dose of 50 milligrams per day (mg/day) must be stable (that is, no adjustment of the dose) for at least 4 weeks prior to baseline (Visit 2).
* Immunosuppressive therapy: If receiving immunosuppressive therapy, the dosage must be stable for at least 4 weeks prior to baseline (Visit 2).

HES Cohort:

* Documented HES diagnosis, defined as history of persistent eosinophilia \>1500 cells/µL without secondary cause on 2 examinations ≥1 month apart and evidence of eosinophil-mediated organ involvement.
* Symptomatic active HES, or history of a prior flare, or considered eligible based on disease severity per investigator judgement.

* Previous receipt of benralizumab in an interventional clinical study.

EGPA Cohort:

* Diagnosed with granulomatosis with polyangiitis (previously known as Wegener'granulomatosis) or microscopic polyangiitis.

* Life-threatening EGPA: imminently life-threatening EGPA disease within 3 months prior to screening (Visit 1) and through first administration of IP at baseline (Visit 2), as per Investigator judgement.

HES Cohort:
