NB: High dose ICS defined according to GINA
• One documented blood EOS (%) or absolute count in the last 12 months
• Twelve months of documented baseline data in medical records or asked on study visit day including asthma medication, especially oral corticosteroid (OCS) treatment and history of asthma exacerbations (number and severity)
• Evidence of one pre-bronchodilator forced expiratory volume in the first second (FEV1) in last 12 months or on study visit day
• 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

• Concurrent biologics for asthma except for stable allergen immunotherapy (defined as a stable dose and regimen at the time of the study visit). Acceptable washout periods for other asthma biologics:

  1. Other eosinophil lowering products indicated for asthma (including mepolizumab or reslizumab): at least 4 months.
  2. Prior omalizumab use: at least 1 month
• 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
