Study Endpoints
Primary Endpoints
Time to first CompEx Asthma event
12 weeks

The CompEx Asthma is a composite endpoint for exacerbations that captures asthma-worsening episodes based on combination of diary events (worsening in daily PEF, asthma symptoms and rescue medication use) plus severe asthma exacerbation events. Diary events are defined by threshold and slope criteria using the following morning/evening diary variables: * PEF * Asthma symptom score (0 to 3) * Use of rescue medication
