Evidence of asthma as documented by either: - Airway reversibility (FEV1 ≥12% and 200 mL) demonstrated at Visit 1, Visit 2, or Visit 3 using the Maximum Post-bronchodilator Procedure OR - Documented reversibility in the previous 24 months prior to Visit 1 OR - Airway hyperresponsiveness (PC20 FEV1 methacholine concentration ≤8mg/mL) documented in the previous 12 months prior to planned date of randomization OR - Airflow variability in clinic FEV1 ≥20% between 2 consecutive clinic visits documented in the 12 months prior to the planned date of randomization (FEV1 recorded during an exacerbation should not be considered for this criterion).
10. At least 1 documented asthma exacerbation in the previous 12 months prior to the date informed consent is obtained.
11. Optimized OCS dose reached at least 2 weeks prior to randomization
12. Additional asthma controller medication must not have been initiated during run in/optimization period (not applicable for management of exacerbations during screening/ run in optimization phase).
13. At least 70% compliance with OCS use.
14. At least 70% compliance with usual asthma controller ICS-LABA.
15. Minimum 70% (ie. 10 of 14 days) compliance with asthma daily diary (morning and evening diary) between each study Visit from 1 to 6. |
|
E.4 | Principal exclusion criteria |
1. Clinically important pulmonary disease other than asthma or ever been diagnosed with pulmonary or systemic disease, other than asthma, that are associated with elevated peripheral eosinophil counts.
2. Any disorder, including, but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological,musculoskeletal, infectious, endocrine, metabolic,hematological, psychiatric, or major physical impairment that is not stable in the opinion of the Investigator and could: − Affect the safety of the patient throughout the study − Influence the findings of the studies or their interpretations − Impede the patient’s ability to complete the entire duration of study.
3. Acute upper or lower respiratory infections requiring antibiotics or antiviral medication within 30 days prior to the date informed consent is obtained or during the screening/run-in period.
4. Any clinically significant abnormal findings in physical examination, vital signs, hematology, clinical chemistry, or urinalysis during screening/run-in period, which in the opinion of the Investigator, may put the patient at risk because of his/her participation in the study, or may influence the results of the study, or the patient’s ability to complete entire duration of the study.
5. History of life-threatening asthma.
6. Asthma control reached at an OCS dose of ≤5mg during run-in/OCS optimization phase.
7. Qualifies for 3 consecutive dose reductions at Visits 2-4 and continues to meet OCS dose reduction criteria at Visit 5.
8. Receipt of oral corticosteroids, other than prednisone or prednisolone, as the maintenance oral steroid controller for asthma symptoms from Visit 1 and throughout the study. |
