Summary

Approximately 300 million people have asthma worldwide and 400,000 people died from asthma globally in 2015 (GINA Asthma). Singapore's asthma mortality and hospitalisation rates are several times higher than OECD countries. Spot Blood eosinophil count (BEC) during an acute exacerbation of asthma was a predictor of more severe respiratory failure and was associated with future acute health care utilization (HR 1.8, 95% CI 1.1-2.9, p=0.02) in a previous study conducted across 4 ICUs in Singapore. Benralizumab, an anti-IL5 receptor α monoclonal antibody causes rapid depletion of blood eosinophils and reduces asthma exacerbations when given over 12-month duration in patient with Severe Eosinophilic Asthma. However, the efficacy of Benralizumab when given during an acute exacerbation of asthma in reducing future exacerbations or severity of asthma exacerbation is relatively unexplored. A Phase 2A randomized double-blind placebo-controlled trial involving the use of one dose of the intravenous formulation of Benralizumab (0.3 mg/kg or 1.0mg/kg) in patients presenting with acute asthma exacerbation did not demonstrate difference in the proportion of subjects with \>/=1 asthma exacerbation at 12 weeks when compared to placebo (33.3% vs. 38.9%; P=0.67). However, compared with placebo, Benralizumab reduced asthma exacerbation rates by 49% (3.59 vs 1.82; P=0.01) and exacerbations resulting in hospitalization by 60% (1.62 vs 0.65; P=.02) in the combined groups at 12 weeks (secondary outcomes).

Benralizumab, an anti-IL5 receptor α monoclonal antibody causes rapid depletion of blood eosinophils and reduces asthma exacerbations when given over 12-month duration in patient with Severe Eosinophilic Asthma.

This study aims to look at whether subcutaneous administration of Benralizumab when initiated during an acute severe asthma exacerbation and then continued over 48 weeks period can increase time to first exacerbation compared to placebo as well as other key secondary outcome such as hospital readmission and health care utilization.

We hypothesise that administration of Benralizumab when initiated during an acute severe asthma exacerbation and then continued over 48 weeks period can increase time to first exacerbation compared to placebo as well as other key secondary outcome such as hospital readmission and health care utilization.
