Eligibility Criteria
- Ages
- 0 years to 17 years (0-17 Years)

- Yes
Inclusion Criteria
- •Capable of giving assent (signing the assent form) to participate in the study, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol. 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.
- •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% of the predicted normal value or pre-BD FEV1/FVC ratio < 0.85 required at Visit
- •Patients with ≥ 25 % increase in 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 method of contraception (confirmed by the investigator) for the duration of the study and for 12 weeks after the last dose of IP. Highly effective methods defined in protocol
- •Patient and the caregiver (where applicable) must be willing to and be able to answer questionnaires that are part of the study procedures, as listed in the ICF, the assent form, and the CSP.
- •Male or female patients aged ≥ 6 to < 18 years old at the time of signing the assent form and their caregivers signing the informed consent form.
- •Patients with physician-diagnosed severe eosinophilic asthma for at least 12 months prior to Visit
Exclusion Criteria
- •Clinically important pulmonary disease other than asthma as defined in protocol.
- •A helminth parasitic infection as defined in protocol.
- •A history of known immunodeficiency including HIV infection.
- •Active liver disease.
- •Current use of any oral or ophthalmic non-selective β adrenergic antagonist (eg, propranolol).
- •Use of immunosuppressive as defined in protocol. Chronic maintenance corticosteroid for the treatment of asthma is allowed.
- •Receipt of immunoglobulin or blood products as defined in protocol.
- •Receipt of any marketed or investigational biologic as defined in protocol.
- •Previously received benralizumab (MEDI-563).
- •Receipt of live attenuated vaccines as defined in protocol.
Outcomes
Primary Outcomes
Time to first asthma exacerbation defined as a worsening of asthma requiring: • Use of systemic corticosteroid (or a temporary increase) for at least 3 days; a single depo-injectable dose, OR • An emergency room visit due to asthma OR • Hospitalisation due to asthma

Secondary Outcomes
- Change from baseline, during the DB treatment period, in the following measures: ACQ-IA, Asthma symptom score, Rescue medication use, Night-time awakenings due to asthma, PEF
- • Serum benralizumab trough concentration • Anti-benralizumab antibodies
- Change from baseline, during the DB treatment period, in PAQLQ-IA total score
- Change from baseline, during the DB treatment period, in spirometry, including pre-dose/pre-bronchodilator FEV1 and post-bronchodilator FEV1
- The AAER in the DB treatment period
- Safety: AEs/SAEs : Occurrence/frequency ; Relationship to the IP as assessed by the investigator ; Intensity ; Seriousness ; Death ; AEs leading to discontinuation of IP ; Vital signs ; Clinical laboratory parameters
- the Open-Label Extension;Period: AEs and SAEs
