Brief Summary:
The main aim of this study is to investigate the change in asthma control after 6 months of therapy in patients treated with benralizumab biologic therapy for severe eosinophilic asthma under real-life conditions in a pulmonary care setting in Germany. The study also aims to investigate Quality-of-Life (QoL), the early treatment response, treatment effectiveness and the change in asthma control over time, following benralizumab therapy. This study will also describe the physician-chosen reasons for starting beralizumab therapy or switching to benralizumab therapy.

Outcome Measures

Primary Outcome Measures :
  1. The change in asthma control after 6 months of treatment in anti-IL5/IL5R naïve patients initiated with benralizumab treatment [ Time Frame: Baseline and 6 months after baseline ]
    Change from baseline in (Asthma Control Test - questionnaire) ACT score after 6 months treatment in anti-IL5/IL5R naïve patients. ACT is a simple, validated, 5-item tool giving a total score from 5 (worst control) to 25 (best control). Scores of 20 to 25 denote well-controlled asthma, scores ≤19 identifies patients with poorly controlled asthma. The minimum clinically important difference (MCID) is reported to be 3 points.


Secondary Outcome Measures :
  1. The investigator reported treatment effectiveness after 6 months of treatment in anti-IL5/IL5R naïve patients initiated with benralizumab treatment [ Time Frame: 6 months after first treatment ]
    Investigator-reported treatment effectiveness using GETE (Global Evaluation of Treatment Effectiveness) after 6 months of treatment. GETE grades overall treatment effectiveness using the following criteria: excellent (complete control of asthma); good (marked improvement of asthma); moderate (discernible, but limited improvement in asthma); poor (no appreciable change in asthma); or worsening (of asthma).

  2. The change in health-related quality of life (HRQL) in anti-IL5/IL5R naïve patients initiated with benralizumab treatment [ Time Frame: Baseline and 6 months after first treatment ]
    Change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score and domain scores (symptoms, activity and impact score) after 6 months treatment in anti-IL5/IL5R naïve patients. SGRQ is a validated, 50-item questionnaire, giving scores ranging from 0 (best health status) to 100 (worst health status). The SGRQ yields a total score and 3 domain scores (symptoms, activity, and impacts). The total score indicates the impact of disease on overall health status. A difference of four units in the SGRQ total score is considered the MCID.

  3. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 7, ACQ-6 [ Time Frame: Baseline and day 7 after first treatment ]

    Change from baseline in ACQ-6 (Asthma-Control-Questionnaire-6) score after 7 days of treatment in anti-IL5/IL5R naïve patients.

    ACQ-6 is a validated questionnaire based on 5 symptoms questions (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing), and daily rescue bronchodilator use. Each item is scored on a 7-point scale (0=no impairment; 6=maximum impairment), and the ACQ score is the mean of these items. The MCID is greater than or equal to 0.5.


  4. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 7, VAS-1 [ Time Frame: Baseline and day 7 after first treatment ]
    Change from baseline in patient satisfaction, measured on Visual Analogue Scale (VAS), after 7 days of treatment in anti-IL5/IL5R naïve patients. VAS Scores ranged from "extremly satisfied" (0 mm) to "not at all satisfied" (100 mm).

  5. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 7, VAS-2 [ Time Frame: Baseline and day 7 after first treatment ]
    Change from baseline in patient symptoms, measured on Visual Analogue Scale (VAS), after 7 days of treatment in anti-IL5/IL5R naïve patients. VAS Scores ranged from "not at all bothersome" (0 mm) to "extremly bothersome" (100 mm).

  6. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 14, ACQ-6 [ Time Frame: Baseline and day 14 after first treatment ]
    Change from baseline in ACQ-6 (Asthma-Control-Questionnaire-6) score after 14 days of treatment in anti-IL5/IL5R naïve patients. ACQ-6 is a validated questionnaire based on 5 symptoms questions (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing), and daily rescue bronchodilator use. Each item is scored on a 7-point scale (0=no impairment; 6=maximum impairment), and the ACQ score is the mean of these items. The MCID is greater than or equal to 0.5.

  7. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 14, VAS-1 [ Time Frame: Baseline and day 14 after first treatment ]
    Change from baseline in patient satisfaction, measured on Visual Analogue Scale (VAS), after 14 days of treatment in anti-IL5/IL5R naïve patients. VAS Scores ranged from "extremly satisfied" (0 mm) to "not at all satisfied" (100 mm).

  8. The early treatment response in anti-IL5/IL5R naïve patients initiated with benralizumab treatment, day 14, VAS-2 [ Time Frame: Baseline and day 14 after first treatment ]
    Change from baseline in patient symptoms, measured on Visual Analogue Scale (VAS), after 14 days of treatment in anti-IL5/IL5R naïve patients. VAS Scores ranged from "not at all bothersome" (0 mm) to "extremly bothersome" (100 mm).

  9. The change of asthma control over time and the maintained response after initiation of benralizumab treatment in anti-IL5/IL5R naïve patients initiated with benralizumab treatment using ACT [ Time Frame: Date of enrollment until end of follow-up (approx. 24 months after enrollment) ]
    Change from baseline in asthma control at each visit during the study period, using ACT in anti-IL5/IL5R naïve patients. ACT is a simple, validated, 5- item tool giving a total score from 5 (worst control) to 25 (best control). Scores of 20 to 25 denote well-controlled asthma, scores ≤19 identifies patients with poorly controlled asthma. The minimum clinically important difference (MCID) is reported to be 3 points.

  10. The change of asthma control over time and the maintained response after initiation of benralizumab treatment in anti-IL5/IL5R naïve patients initiated with benralizumab treatment using ACQ-6 [ Time Frame: Date of enrollment until end of follow-up (approx. 24 months after enrollment) ]
    Change from baseline in asthma control at each visit during the study period, using ACQ-6 in anti-IL5/IL5R naïve patients. ACQ-6 is a validated questionnaire based on 5 symptoms questions (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing), and daily rescue bronchodilator use. Each item is scored on a 7-point scale (0=no impairment; 6=maximum impairment), and the ACQ score is the mean of these items. The MCID is greater than or equal to 0.5.
