Efficacy and Safety of Benralizumab in Patients With Non-cystic Fibrosis Bronchiectasis (MAHALE)
A Multicentre, Randomised, Double-blind, Parallel-group, Placebo-controlled, 52 Week, Phase III Study With an Open-label Extension to Evaluate the Efficacy and Safety of Benralizumab in Patients With Non-Cystic Fibrosis Bronchiectasis (MAHALE)
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).

- If receiving prophylactic systemic or inhaled antibiotics to prevent bronchiectasis exacerbations, the dose/regimen must be stable for at least 3 months prior to the screening visit and remain stable throughout the DB period of the study. If prophylactic macrolides have been recently discontinued, patients must have been off treatment for at least 3 months prior to randomisation. In all other cases of prophylactic antibiotic use, ≥ 4 weeks wash out period should be in place after the 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.
