This is a prospective, single-arm, multicenter, observational study to evaluate the safety and effectiveness of tezepelumab from treatment initiation up to 24 weeks in patients who are prescribed tezepelumab according to its approved indication in South Korea.
The effectiveness assessment will estimate the proportion of patients with improved asthma control or a clinically meaningful improvement in SNOT-22 scores, from treatment initiation up to 24 weeks after the initiation of tezepelumab.
This study design will reflect the actual management of these subjects in routine clinical practice. The treating physician will determine the treatment plan, as well as the frequency of laboratory and clinical assessment, if necessary, based on routine practice.
All patients will be evaluated for safety during tezepelumab use (24 weeks) or within 30 days after the last administration of tezepelumab if the patients discontinued tezepelumab before 24 weeks.
