Assessment

Primary outcomes

During a 4-month observation period (up to 1 year), all participants will be divided into treatment responders and non-responders using FEV1.0, ACT score, GETE score, and frequency of acute exacerbations.

Key secondary outcomes

1, To analyze association between gene expression data from whole blood cells and effect of Tezepelumab, first, the difference in baseline gene expression between the responder and non-responder groups will be analyzed. In addition, changes in gene expression will be analyzed before and after tezepelumab treatment in the responder group and non-responder group, or in all patients. Thereafter, a cluster analysis will be performed by integrating gene sets with changes and clinical information.

2, If important genes involved in treatment response are identified, serum protein concentrations will be measured to determine whether these can be used as biomarkers.

3, To analyze the difference in the effect of Tezepelumab between type2 severe asthma patients and non-type 2 severe asthma patients in terms of clinical and gene expression information.

4, To clarify the effect of tezepelumab in terms of TSLP genetic polymorphisms.

5, Furthermore, using the R package, Coexpression analysis and consensus clustering will be performed, and analysis that is not bound by existing clinical information will also be performed. And the correlation between genetic information and clinical information will be analyzed.

Other related information

The integration of information from molecular genetic analyses, such as comprehensive analyses of gene expression and analyses of gene polymorphisms, may reveal not only unknown mechanisms of action of Tezepelumab but may also lead to the elucidation of the pathophysiological mechanisms of severe asthma (particularly, non-type 2 severe asthma).
