Study design details

Study design

Observational longitudinal study

Main study objective

Objective 1: To describe the patterns of remission over time and the patient characteristics of various patterns of remission.
Objective 2: To investigate the effect of remission on long-term clinical outcomes of asthma between those that graduate to remission at 12-months post-initiation of biologic therapy compared to those that do not.

Setting

The study population will be extracted from the International Severe Asthma Registry database (data collected between 2017 and 2025). Eligibility criteria include having initiated biologic therapy, being adult at initiation, and having follow-up data for at least 2 years after initiation.

Comparators

Patients who met remission criteria in the first year of follow-up versus those who did not.

Outcomes

Asthma clinical remission, exacerbations, long-term OCS use, asthma symptom control, lung function.
