Primary
| Measure | Time frame |
|---|---|
| Main Objective: To analyze the protective effect of azelastine/fluticasone propionate against exercise-induced airway narrowing by measuring inspiratory and expiratory airflow limitation and airway resistance and reactance in asthmatic children. ;Timepoint(s) of evaluation of this end point: At day 1 and after 3 weeks; Secondary Objective: -Analyze the reduction in exercise-induced increase of airway resistance at low frequency, measured with FOT, after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo. -Analyze the reduction in exercise-induced decrease of airway reactance at low frequency, measured with FOT, after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo. -Analyze the increase in quality of life, measured with the pediatric asthma quality of life questionnaire (PAQLQ), after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo. -Analyze the increase in control of asthma, measured with the asthma control test (ACT), after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo ; Primary end point(s): -The reduction in exercise-induced fall in FEV1 after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo. -The reduction in exercise-induced fall in MIF50 after three weeks of treatment with azelastine/fluticasone propionate in comparison with a placebo. | — |
