A Non-interventional, Prospective Study With Benralizumab

This is a prospective, non-interventional, single-arm, multicenter study to investigate asthma control, and health-related quality of life (HRQL), lung function and asthma medication intake in severe eosinophilic asthma patients treated with benralizumab in a real-life setting in Germany.

This is a prospective observational study to investigate the asthma control and health realted quality of life (HRQL) of benralizumab treated patients in routine clinical practice, their asthma medication intake, and their changes in asthma medication during the study, up to 52 weeks.

The asthma control will be analyzed by using the Asthma Control Test (ACT) and the Asthma Impairment and Risk Questionnaire (AIRQ®) at different timepoints during the study period either collected by the investigator or self-reported by the patient. In addition, health realted quality of life will be assessed at baseline and routine follow-up visits using the mini Asthma Quality of Life Questionnaire (miniAQLQ) which is collected by the investigator. To investigate the medication intake and assess the changes in asthma medication, the patients will record their weekly medication intake in a paper-based or an electronic medication diary throughout the study.

* After full explanation, patients must have signed an informed consent form (ICF) indicating that they understand the purpose of, and the procedures required for the study and are willing to participate in the study

* Concurrent asthma biologic therapy
* Helminth parasitic infection diagnosed within 24 weeks prior to the date informed consent was obtained that had not been treated with, or had failed to respond to standard of care (SOC) therapy
* Any other pulmonary disease than asthma that, in the investigator's point of view, would have an impact on the interpretation of results
* An acute or chronic condition that, in the investigator's point of view, would limit the patient's ability to complete questionnaires or participate in this study or impact the interpretations of results
* Current or history of malignancy within 5 years before the enrolment date with the following exceptions:

  * In-situ carcinoma of the cervix where curative therapy has been completed and patients are in remission for at least 12 months prior to enrolment date
