AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children and teenagers with EGPA or hypereosinophilic syndrome (HES) to test the safety and effect of benralizumab.
- Age
- 6 to under 18 years old
- Sex
- Boys and girls can both join.
- Disease stage
- EGPA cohort: on a stable corticosteroid dose. HES cohort: persistent eosinophilia above 1500 cells/µL without another cause, with organ involvement, and active symptoms or a past flare.
- Earlier treatment
- EGPA cohort: stable oral corticosteroid dose for at least 4 weeks before baseline, and stable immunosuppressive dose for at least 4 weeks if taken. Cannot have had benralizumab in a study before.
- Biomarker or test result
- HES cohort: eosinophil count of at least 1000 cells/µL at screening, and a documented negative test for the FIP1L1-PDGFR fusion gene.
Main reasons for not taking part
- Any current or past cancer
- Past severe allergic reaction (anaphylaxis) to a biologic therapy or vaccine
- Other significant long-term health problems in a body system
- Life-threatening EGPA or HES
- Granulomatosis with polyangiitis, microscopic polyangiitis or systemic mastocytosis

Phase 3, Open-label Trial to Evaluate Safety, Pharmacokinetics, and Efficacy of Benralizumab in Children With Eosinophilic Diseases (CLIPS)
The main purpose of study is to assess the safety, tolerability, pharmacokinetics (PK), and efficacy of benralizumab.
Inclusion: All Cohorts:; Male or female participants must be aged 6 to < 18 years of age at the time of signing the assent form and their caregiver signing the informed consent form; Body weight greater than (>=) 15 kilograms (kg); 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; AEC ≥1000 cells/µL at screening (Visit 1); Documented negative testing for Fip1-like 1 gene fused with the platelet-derived growth factor receptor alpha gene (FIP1L1-PDGFR) fusion tyrosine kinase gene translocation.
Exclusion: Previous receipt of benralizumab in an interventional clinical study; EGPA Cohort:; Diagnosed with granulomatosis with polyangiitis (previously known as Wegener'granulomatosis) or microscopic polyangiitis; EGPA relapse: any deterioration in EGPA and/or organ-threatening EGPA that per Investigator judgement renders participants unstable in their EGPA within 3 months prior to screening (Visit 1) and through first administration of IP at baseline (Visit 2); 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:; Any current malignancy or history of malignancy; History of anaphylaxis to any biologic therapy or vaccine; Known, pre-existing, clinically significant endocrine, autoimmune, metabolic, neurological, renal, gastrointestinal, hepatic, haematological, respiratory, or any other system abnormalities; All Cohorts:; Life-threatening HES or HES complications, as judged by the investigator; Hypereosinophilia of unknown significance (HE-US); Diagnosis of systemic mastocytosis.
