• Study description:
  A registry-based historical cohort study of severe asthma patients who initiated anti-IL5/5R biologic treatments. Changes in clinical outcomes (lung function and exacerbations) and changes in a biomarker (blood eosinophil count) over time following initiation of the biologic will be related to each other and to baseline patient characteristics as well as to other prior and ongoing asthma treatments. ; The main aim of the study is to identify patient characteristics associated with biological and/or clinical treatment failure at different times after initiation of anti-IL5/5R biologics and the extent to which these are linked or independent events. ; This information will help clinicians in selecting the best treatment for patients and provide important evidence on the information that should be collected before and after biologic initiation.
