Clinical Trial for Severe Eosinophilic Asthma (Variable Duration)

Treatment: Injection Age: 6 Years

Children or adolescents (aged ≥ 6 to < 18 years old) with a diagnosis of severe asthma confirmed, evaluated, and managed by the clinical site for
≥ 6 months prior to Visit 1, may qualify to participate in this study. Patients must have a diagnosis of eosinophilic asthma, defined by regional
guidelines, for at least 12 months prior to Visit 1.

We are looking for children and adolescents who:
• have had asthma episodes over the last year that required steroid medication or hospital treatment
• are already using an inhaled steroid plus at least 1 additional asthma medication

Participants will receive investigational treatment (active study drug) or placebo, via injection (every 4-8 weeks). Study treatment and study-related assessments will be provided at no cost. Reimbursement for study-related expenses may be provided. Participants can stay on their usual asthma medication throughout the study.

Length of study participation and number of study visits will vary for each participant, depending on when they experience their first asthma
exacerbation. After an exacerbation, participants will then enter an open-label extension period for a variable length of time (56 or 112 weeks,
based on age). During the extension period, all participants will receive the investigational study drug.

Please get in touch if this may be of interest to you/your child. There is no obligation to take part just by asking for more information.

Study Description

  • 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.

  • Intervention/Treatment:

    Drug: Benralizumab
    Drug: Placebo
  • Phase:

    Phase 3

  • Ages Eligible for Study:

    6 Years and 18 Years (Child)

  • Sexes Eligible for Study:


Inclusion Criteria:

Capable of giving assent (signing the assent form) to participate in the study. The caregiver of the patient must be capable of giving written informed consent for the patient’s participation in the study. Consent and assent forms must be completed prior to any study specific procedures.
Patient and the caregiver (where applicable) must be willing to and be able to answer questionnaires that are part of the study procedures.
Male or female patients aged ≥ 6 to < 18 years old. Patients with a diagnosis of eosinophilic asthma, defined by regional for at least 12 months prior to Visit 1. Patients with a diagnosis of severe asthma confirmed, evaluated, and managed by the clinical site for ≥ 6 months prior to Visit 1. Patients with an exacerbation history of asthma exacerbations (defined as a requirement for systemic corticosteroids and/or hospitalization) within 12 months prior to Visit 1, OR, 2 asthma exacerbations (defined as a requirement for systemic corticosteroids and/or hospitalization) 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 1 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 and documentation of elevated eosinophils in bronchoalveolar lavage (BAL), sputum, or bronchial biopsy 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 70% 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. Pre-BD FEV1 ≤ 95% PN or pre-BD FEV1/FVC ratio < 0.85 required. Patients with ≥ 25 % increase in mean pre-BD FEV1 value during the screening period will be screen failed. ACQ-IA ≥ 1.5 with no meaningful improvement (ACQ-IA change ≤ -0.5) between 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 and acceptable method of contraception Exclusion Criteria: Clinically important pulmonary disease other than asthma or patients who have ever been diagnosed with pulmonary or systemic disease, other than asthma, that are associated with elevated peripheral eosinophil counts 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 4 months or 5 half-lives prior to Visit 1 Previously received benralizumab (MEDI-563). Participation in another interventional clinical study Patients with known hypersensitivity to benralizumab or any of the excipients of the product.
