Description of intervention(s) / exposure
Severe asthma is defined as ‘Uncontrolled asthma which can result in risk of frequent severe exacerbation (or death) and/or adverse reactions to medications and/or chronic morbidity (including impaired lung function or reduced lung growth in children).’

The Australian Benralizumab Registry will:
· collect and report on data from people with severe refractory eosinophilic asthma who receive benralizumab:
a) as part of the PBS subsidised benralizumab treatment cycle, and the Pharmaceutical Benefits Scheme (PBS) Section 100 Special Authority Program,
or
b) who receive benralizumab for severe refractory eosinophilic asthma outside of the PBS restrictions.

Patients will be followed prospectively for 2 years and data collection will be conducted every 6 months. At patients' visits, data on demographics, anthropometrics, Quality of Life and clinical data will be collected.

Statistical methods / analysis
The sample size for this study was calculated using GPower (Erdfelder et al. 1996). This current study hypothesis is that benralizumab improves asthma control in severe refractory eosinophilic asthma, measured using the ACQ-5. We would aim to detect moderate magnitude of effect of benralizumab therapy on severe refractory eosinophilic asthma control. To obtain a power of 0.80, n = 74 participants will need to be recruited. With an expected drop-out rate of 30% (Lane, 2008), a minimum of approximately 100 patients will be required for this study.

Change in ACQ-5 from baseline to first continuation visit [likely 6 months] will be computed and expressed as mean and sd/ 95% confidence intervals (CI).
Proportion (95% CI) with change in ACQ-5 greater than 0.5.
