• People who have been using a daily combination inhaler (containing both a steroid and a long-acting bronchodilator) for at least 12 weeks before the first study visit, with no changes to their asthma medications in the 6 weeks before that visit, and a stable steroid dose within a specific range (confirm with trial site for exact dosing details).
• People who, in the year before the second study visit, had a documented medical contact for sudden worsening asthma symptoms, or had a documented temporary change in their asthma treatment as part of an agreed asthma action plan.
