Change in Patient-Reported Outcomes in Severe Eosinophilic Asthma Patients Treated With Benralizumab Under Real-life Conditions

Prior treatment

• Concomitant treatment with any other biologic for any indication
• Patients already treated with benralizumab
• Concurrent biologics for asthma are not allowed except for stable allergen immunotherapy (defined as a stable dose and regimen at the time of enrolment). Acceptable wash-out periods for other asthma biologics: ≥30 days from last dose of previous biologic

Other illness

• Clinically important pulmonary disease other than asthma including: chronic obstructive pulmonary disease (as main diagnosis), bronchiectasis, idiopathic pulmonary fibrosis, pulmonary hypertension, alpha-1-antitrypsin-deficiency, and malignancy of any kind (NB: the following conditions are permitted: nasal polyposis, allergic rhinitis, atopic dermatitis, non-idiopathic pulmonary fibrosis).
• An acute or chronic condition that, in the investigator's opinion, would limit the patient's ability to complete questionnaires or participate in this study or impact the interpretations of results.

Other

• Pregnancy or lactation period
• Participation in an observational trial that might, in the investigator's opinion, influence the assessment for the current study, or participation in a randomized clinical trial in the last 3 months

• Male or female patients aged 18 years or older with confirmed diagnosis of severe asthma according to the ATS/ERS and local German guidelines
• Decision was made by the investigator (regardless of this NIS) to start treating the patient with benralizumab according to severe eosinophilic asthma indication (NB: can include patients that are switched from another EU approved biologic treatment if required for a medical reason).
• Patients must be able and willing to read and comprehend written instructions, and comprehend and complete the questionnaires required by the protocol
• After full explanation, patients must have signed an informed consent document indicating that they understand the purpose of and the procedures required for the study and are willing to participate in the study.
