Brief Summary

A study to evaluate the efficacy and safety of benralizumab administered subcutaneously in patients ≥ 6 to \< 18 years of age with severe eosinophilic asthma, including a well-documented history of asthma exacerbations and uncontrolled asthma receiving high-dose inhaled corticosteroid (ICS) plus at least one additional controller medication.

Conditions

Asthma

Keywords

Outcome Measures

Primary Outcomes (1)

• Time to first asthma exacerbation

  The effect of benralizumab on asthma exacerbations in paediatric and adolescent patients with uncontrolled asthma will be evaluated.

  From Baseline (Week 0) to End of Treatment (EOT) in DB treatment period

Secondary Outcomes (11)

• Change from baseline, during the DB treatment period in Interviewer-Administered Version of the Asthma Control Questionnaire (ACQ-IA)

  From Baseline (Week 0) to EOT in DB treatment period

• Change from baseline, during the DB treatment period in Asthma symptom score

  From Baseline (Week 0) to EOT in DB treatment period

• Change from baseline, during the DB treatment period in rescue medication use

  From Baseline (Week 0) to EOT in DB treatment period

• Change from baseline, during the DB treatment period in night-time awakenings due to asthma

  From Baseline (Week 0) to EOT in DB treatment period

• Change from baseline, during the DB treatment period in peak expiratory flow (PEF) measurement at home

  From Baseline (Week 0) to EOT in DB treatment period

Other Outcomes (2)

• Number of patients with Adverse events (AEs) and Serious adverse events (SAEs)

  From Screening period until EOT DB treatment period

• 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.

• Life-threatening asthma.
• Asthma exacerbation requiring use of systemic corticosteroids or increase in maintenance dose of OCS within 2 weeks prior to Visit 2a or acute upper/lower respiratory infection that requires antibiotics or antiviral medication within 2 weeks prior to the first dose of the IP (Visit 2b).
• 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.
• Receipt of immunoglobulin or blood products within 30 days prior to Visit 1.
• Receipt of any marketed or investigational biologic within 5 half-lives prior to Visit 2.
