Description of intervention(s) / exposure
A 4 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, 24, 36, 48 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.

Outcomes
Primary outcome [1] 307016 0
Change in asthma control score
(Juniper Asthma Control Questionnaire - ACQ5)
Timepoint [1] 307016 0
Change in asthma control score is assessed at 4(3-5), 7(6-8), 12, 18, and 24, 36 and 48 months post-commencement of treatment. Asthma control is assessed at each time-point for the week preceding.
Primary outcome [2] 307017 0
Number of severe exacerbations
Severe asthma exacerbations identified as those requiring use of systemic corticosteroids prescribed or supervised by a physician, hospitalisation or an emergency department visit requiring systemic corticosteroids. Severe exacerbations are captured via clinical staff report/medical record review.
Timepoint [2] 307017 0
The number of severe exacerbations that have occurred since the previous visit are assessed at 4(3-5), 7(6-8), 12, 18, 24, 36 and 48 months post-commencement of treatment.
Secondary outcome [1] 350363 0
Quality of life
(Juniper Asthma Quality of Life Questionnaire)
Timepoint [1] 350363 0
Quality of life is assessed at 4(3-5), 7(6-8), 12, 18 and 24 months post-commencement of treatment. The AQLQ is completed at each time-point for the 2 weeks preceding.
Secondary outcome [2] 350364 0
Blood eosinophil levels
Timepoint [2] 350364 0
Blood eosinophil level is measured at 4(3-5) months, 12 months and 24, 36 and 48 months after commencement of treatment.
Secondary outcome [3] 350365 0
Lung function (FEV1, FVC) is assessed using standard spirometers in the clinic or pulmonary function laboratory.
Timepoint [3] 350365 0
Spirometry is performed to determine lung function at 4(3-5), 7(6-8), 12, 18, 24, 36 and 48 months post-commencement of treatment.
Secondary outcome [4] 350366 0
Health care resource utilisation is assessed via patient interview and medical record review.
Timepoint [4] 350366 0
Health care resource utilisation is assessed at 4(3-5), 7(6-8), 12, 18, 24, 36 and 48 months post-commencement of treatment. Health care resource utilisation since the previous assessment is assessed.
Secondary outcome [5] 350367 0
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).
Timepoint [5] 350367 0
during the week following administration of mepolizumab and during the 4-year followup
Secondary outcome [6] 441132 0

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.
