E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective is to compare the efficacy and the safety of masitinib at 6 mg/kg/day versus placebo in the treatment of patients with Severe Persistent Asthma treated with oral corticosteroids. Primary endpoint: Asthma exacerbation rate (severe and moderate exacerbations) at 36 weeks adjusted on the available person-time (time to end of treatment) |
|
E.2.2 | Secondary objectives of the trial |
• Asthma Control Questionnaire (ACQ) Score at 12, 20, 28 and 36 weeks • Moderate and severe asthma exacerbation rate at 12, 20, 28 and 36 weeks • Severe asthma exacerbation rate at 12, 20, 28 and 36 weeks • Time to first asthma exacerbation (severe or moderate) • Percentage of patient experiencing at least one exacerbation at 12, 20, 28 and 36 weeks • Asthma symptom score at all time points • Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC), Forced Expiratory Flow between 25-75% of FVC (FEF25-75) at 12, 20, 28 and 36 weeks • Morning and evening Peak Expiratory Flow Rate (PEFR) at 12, 20, 28 and 36 weeks • Use of rescue medication for asthma at 12, 20, 28 and 36 weeks • Quality of Life assessment: AQLQ score at each visit at 12, 20, 28 and 36 weeks |
