Description of intervention(s) / exposure
Observational post-marketing surveillance registry of adults receiving mepolizumab treatment for severe eosinophilic chronic rhinosinusitis with nasal polyps.

Participants will participate in 2 structured computer-assisted telephone interviews with a member of the research team, and complete post-interview questionnaires. These are completed at baseline (prior to commencement of mepolizumab treatment) and again 12 months after mepolizumab commencement. Completion of each interview and the questionnaires will take approximately 2 hours. Data from the participants' medical records are also collected for the baseline and 12 month followup assessments (including nasal polyp scores, sinus surgery details).

The participants' response to mepolizumab treatment will be observed (rhinosinusitis/nasal polyps symptoms, requirement for sinus surgery, health-related quality of life, requirement for systemic corticosteroid treatment, adverse drug-related effects, asthma symptom control for participants with asthma diagnosis)

Secondary outcome [5] 422234 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).

Statistical methods / analysis
Summary statistics will be produced for the key variables contained within the registry, such as CRS/NP characteristics, and treatment for baseline data. Mepolizumab treatment clinical response variables will be summarised (eg. nasal obstruction VAS, overall symptoms VAS, requirement for surgery, bilateral endoscopic NP score).

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 categorised by response; comorbidity, phenotypic characteristics. Analysis of normally distributed data will be performed using the unpaired Student’s t test for comparison between two groups. Analysis of non-parametric data will be performed using the Wilcoxon rank sum test for comparison between two groups or the Kruskal-Wallis test with post-hoc test applied to correct for multiple comparisons. Chi2 or Fisher’s exact test will be used to analyse categorical data.
