Patients with a diagnosis of severe asthma confirmed, evaluated, and managed by the clinical site/site network for ≥ 6 months prior to Visit 1.
Patients with an exacerbation history of asthma exacerbations (defined as a requirement for systemic corticosteroids and/or hospitalisation) within 12 months prior to Visit 1, OR,
2 asthma exacerbations (defined as a requirement for systemic corticosteroids and/or hospitalisation) per year within the 2 years prior to Visit 1 AND, one or more of the following:
Currently on stable maintenance oral corticosteroids (OCS) used for at least 3 months prior to Visit 1, OR,
At least one of the 2 exacerbations that occurred in the year prior to Visit 1 resulted in hospitalisation.
Patients on well-documented, stable treatment for asthma with high dose ICS and at least one additional controller medication, such as long-acting β2 agonists (LABA), leukotriene receptor antagonists (LTRA), long-acting muscarinic antagonists (LAMA), or theophylline, since at least 6 months prior to Visit 1.
Eosinophilic airway inflammation that is related to asthma characterised as eosinophilic in nature as indicated by peripheral blood eosinophil count of ≥ 300 cells/μL during screening OR a blood eosinophil count of 150 to 299 cells/μL during screening and documentation of elevated eosinophils in bronchoalveolar lavage (BAL), sputum, bronchial biopsy, or historical eosinophil count ≥ 300 cells/μL within the 2 years prior to Visit 1.
≥ 70% compliance with maintenance asthma medication during the screening period based on the Paediatric Asthma Symptom - Observer reported (PASO) or Asthma Daily Diary.
At least 50% daily PASO or Asthma Daily Diary completion during the entire screening period, with at least 50% PASO or Asthma Daily Diary completion in the 14-day period prior to randomisation.
ACQ-IA ≥ 1.5 at screening and Visit 2a.
Body weight ≥ 15 kg.
Females of childbearing potential (FOCBP) who are sexually active, as judged by the investigator, must commit to consistent and correct use of a highly effective method of contraception.

Any disorder that is not stable in the opinion of the investigator and could affect the safety of the patient during the study, influence the findings of the studies or their interpretations or impede the patient's ability to complete the entire duration of the study.
History of anaphylaxis to any biologic therapy.
Current malignancy, or history of malignancy.
A helminth parasitic infection.
Use of immunosuppressive medication.
