Primary Outcome Measures:
- Change from baseline in sputum eosinophil percentage at week 12 (baseline measurement is defined as sputum eosinophil percentage at Day1 prior to the first dosing). [ Time Frame: Visit 3 (day 1); Visit 5 (day 84) ] [ Designated as safety issue: No ]Sputum induction is performed through the inhalation of hypertonic saline. Sputum is collected and assessed for differential cellular content (absolute numbers and percentages). The primary variable will be summarized by treatment and analyzed using an ANCOVA model with treatment as the fixed effect and the respective baseline value as the covariate.
Secondary Outcome Measures:
- Change from baseline to week 12 in Asthma Control Questionnaire (ACQ) [ Time Frame: Visit 3 (day 1); Visit 5 (day 84) ] [ Designated as safety issue: No ]Participants complete the Asthma Control Questionnaire (ACQ). The ACQ has 7 equally weighted items; 5 on symptom assessment, 1 on rescue bronchodilator use and 1 on airway caliber Forced Expiratory Volume in one second (FEV1) % predicted. Items 1-6 are scored along a 7 point response scale, where 0 = good control and 6 = poor control. The 7th item on % predicted FEV1 (pre-bronchodilator) is scored by clinic staff on a 7 point scale. Secondary variables are summarized by treatment and analyzed using ANCOVA model with treatment as the fixed effect and the respective baseline value as covariate.
- Safety and tolerability of QAW039 in patients with moderate to severe asthma [ Time Frame: Visit 2 (day -14); Visit 3 (day 1); Visit 4 (day 42); Visit 5 (day 84); Visit 6 (day 126) ] [ Designated as safety issue: Yes ]All safety endpoints (including adverse events, laboratory data, vital signs and ECG) will be summarized by treatment group for all patients in the safety population. All data will be included in the analysis regardless of rescue medication use.
