last dose of antibiotic and prior to randomisation

- Must be on airway clearance therapy, physiotherapy, or mucus clearance therapy.The
dose and regimen of these therapies and any drugs used to aid expectoration should be
stable for at least 3 months prior to the screening visit and remain stable throughout
the DB period of the study.

- If receiving inhaled corticosteroid or bronchodilator therapy, the dose and regimen
should be stable with no alteration to dose or formulation for at least 3 months prior
to the screening visit and this should remain stable throughout the DB period of the
study.

- Women of childbearing potential (WOCBP) must have a negative serum and urine pregnancy
test prior to randomization and agree to use a highly effective method of birth
control from enrollment, throughout the study duration, and for 12 weeks after the
last dose of IP.

Summary
Brief summary
This is a multicentre, randomised, double-blind, parallel-group, placebo-controlled, phase
III study originally designed to test the hypothesis that benralizumab will reduce
exacerbation rates compared with placebo on top of standard-of-care therapy in adult patients
with non-cystic fibrosis bronchiectasis with eosinophilic inflammation (NCFB+EI).

All patients who complete the double-blind treatment period (28 to 52 weeks depending on the
timing of patient randomization and when the revised CSP version 3.0 becomes effective) on
investigational product (IP) may be eligible to continue into an open-label extension (OLE)
period during which all patients will receive benralizumab.

The revised OLE period is intended to allow patients approximately 32 weeks of treatment with
open label benralizumab (24 weeks followed by a FU visit 8 weeks after the last dose of IP
for a total of approximately 32 weeks).
