Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Explore if adult asthma patients prescribed fixed dose combinations (budenosid/formoterol (Symbicort®), salmeterol/fluticasone (Seretide®), beclometasone/formoterol (Innovair®)) are optimal treated regarding the mannitol challenge test and the following reversibility test.;Secondary Objective: Explore how the asthma patients score themselves according the Asthma Control Test (ACT), “symptomatic” or “well-treated”. Explore how the Investigator evaluates the patients control of asthma, Asthma Score. ;Primary end point(s): • Mannitol challenge test (Aridol™) + short-acting ß2-agonist – positive response defined as one of the following: o =15% fall in FEV1 from baseline o 10% incremental fall in FEV1 between two consecutive doses in the test o Reversibility test with a short-acting ß2-agonist - increase in FEV1 of =15% ;Timepoint(s) of evaluation of this end point: At the day of the mannitol challenge test, visit nr. 2. | — |
