Study design details

Study design

Observational study, historical cohort study

Main study objective

Objective 1:
To describe the timing of biologic therapy initiation using various proxies of time to initiation

Objective 2:
To assess whether the timing of biologic therapy initiation is associated with the course of the disease in patients with severe asthma, including remission, biomarkers and individual clinical outcomes.

Setting

Data collected at a clinical setting from years 2017-2024

Comparators

Early vs late biologic initiators

Outcomes

Asthma clinical remission, exacerbation, Long-term OCS, asthma control, blood eosinophil count, Fractional exhaled nitric oxide

Data analysis plan

Remission:
- Type: Yes / No, Univariable: Logistic regression

Clinical outcomes:
- Exacerbations, Type: count, Univariable: Negative binomial
- Total OCS, Type: Continuous, Univariable: Linear regression
- Asthma control, Type: Ordinal, Univariable: Ordinal logistic regression
- Lung function, Type: Continuous, Univariable: Linear regression

Biomarkers:
- FeNO, Type: Continuous, Univariable: Median change from baseline to 3 months, 12 month, 2 yrs, 3 yrs (Linear or quantile regression)
- BEC, Type: Continuous, Univariable: Median change from baseline to 3 months, 12 month, 2 yrs, 3 yrs (Linear or quantile regression)
