Description of intervention(s) / exposure
A 2 year observation of patients treated with Mepolizumab for severe asthma.
Prior to starting treatment with Mepolizumab, patients will complete questionnaires concerning their asthma control and health-related quality of life. Details of medical history, asthma exacerbations and medication use are also recorded. Lung function and blood biomarkers (blood eosinophils, serum IgE) are also reported. Follow up data collection is performed at approximately 4, 7, 12, 18 and 24 months after starting treatment. Data collection is aligned with standard clinic visits and assessments. Patients will again complete questionnaires and clinical outcomes will also be reported.

Drug-related adverse events will be assessed by clinical observation/patient report.
Acute and delayed systemic reactions, including hypersensitivity reactions (e.g. anaphylaxis, urticaria, angioedema, rash, bronchospasm, hypotension), have occurred following administration of mepolizumab. These reactions generally occur within hours of administration, but in some instances had a delayed onset (i.e., days).

Statistical methods / analysis
Summary statistics will be produced for the key variables contained within the database, such as asthma characteristics, and asthma treatment for baseline data. Mepolizumab treatment cycles will be described and clinical response variables summarised. Relevant comparisons will be conducted between defined sub-groups and based on subject characteristic variables [e.g. age, sex, treatment intensity, asthma duration, etc]. Subject to data availability, data linkage analysis may be conducted for selected outcome variables.
A target minimum sample size is 100 participants which will give sufficient power to allow precision around point estimates. The likely sample size will be between 200 and 400 participants over the study enrolment period.
Demographic and participant characteristics will be summarised using measures of central tendency (mean, median) and appropriate variance estimates. Proportions of responders, and participants developing adverse events will be reported with 95% confidence intervals. Subgroup analyses will be performed with participants categorized by response; comorbidity, phenotypic characteristics.

Summary
Brief summary
The Australian Mepolizumab Registry (AMR) collects data on individuals with severe refractory asthma who receive mepolizumab for the management of their asthma. This includes those with treatment-resistant severe eosinophilic asthma who receive Pharmaceutical Benefit Scheme (PBS)-subsidised mepolizumab, and those with treatment-resistant severe asthma who receive mepolizumab outside of the PBS scheme.
The AMR provide a mechanism for researchers and clinicians to better understand the use, effectiveness, and safety associated with the treatment of severe asthma with mepolizumab.
