Tezepelumab PRO Study

This study assesses the impact of tezepelumab treatment not only on asthma control but also on cough specific Health-Related Quality of Life (HRQoL). Asthma control can be evaluated using Asthma Control Questionnaire (ACQ). Cough symptom which is one of the symptoms related airway hyperresponsiveness can be assessed via the relevant questionnaire, Leicester Cough Questionnaire (LCQ). There is moderate negative correlation between ACQ and LCQ . Improvements in both asthma control and cough symptom by tezepelumab would clarify effectiveness of Tezepelumab in real-world. Though Tezepelumab is recently approved in Japan, there is no real-world evidence on tezepelumab, particularly on above mentioned symptoms. Thus, this study aims to estimate effectiveness of tezepelumab on asthma and cough symptoms in real world settings.
