- Primary Outcome Measures
Name Time Method Total Number of Asthma Exacerbations 52 Weeks An exacerbation was defined as symptomatic worsening requiring oral/systemic glucocorticoid therapy and/or emergency room visit and/or urgent care center visit and/or hospitalization.
- Secondary Outcome Measures
Name Time Method Asthma Exacerbations 52 Weeks Number of participants with at least 1 exacerbation
QT Interval Corrected Using the Fridericia Formula Measured Via Electrocardiogram (ECG) Baseline and 52 weeks QT interval corrected using the Fridericia formula \[QTc (Frid)\] - Change from baseline to end of treatment
Number of Patients With Shift From Normal to High Rate of Total Ectopic Ventricular Beats as Measured by 24-hour Holter Monitor Assessment Baseline and 2 weeks (visit 4) Total ectopic ventricular (VE) beats - number of participants with shift from normal (\<50) to high (≥50) from baseline to visit 4.
Number of Patients With Shift From Normal to High Rate of Total Ectopic Supraventricular Beats as Measured by 24-hour Holter Monitor Assessment Baseline and 2 weeks (visit 4) Total ectopic supraventricular (VE) beats - number of participants with shift normal (\<50) to high (≥50) from baseline to visit 4.
Total Number of Ventricular Runs as Measured by 24-hour Holter Monitor Assessment Baseline and 2 weeks (visit 4) Total ventricular runs - number of participants with shift normal (\<1) to high (≥1) from baseline to week 2.
Diary Assessments - Rescue-free Day baseline and 52 weeks Calculated as the number of rescue-free days divided by the number of non missing days in the baseline period times 100%. The results are expressed as the change in % rescue-free days in the baseline period and the active treatment period. A rescue-free day was one in which the patient answered "no" to having used rescue medication that day
Diary Assessments - Symptom-free Day baseline and 52 weeks Calculated as the number of symptom-free days divided by the number of non missing days in the baseline period times 100%. The results are expressed as the change in % symptom-free days in the baseline period and the active treatment period. A symptom-free day was one in which the patient answered "no" to having symptoms that day
Diary Assessments - Asthma-control Day baseline and 52 weeks Calculated as the number of asthma control days divided by the number of non missing days in the baseline period times 100%. The results are expressed as the change in % asthma control days in the baseline period and the active treatment period. An asthma control day was one in which the patient answered "no" to having symptoms and "0" to the use of rescue medication that day
Onset of Effect Questionnaire (OEQ) 1 week Number of participants with positive response to Item 5 in questionnaire "During the past week, you were satisfied with how quickly you felt your study medication begin to work." The scale was scored on a 5-point Likert scale from strongly agree to strongly disagree. A positive response was defined as a response of "strongly agree" or "somewhat agree"
Peak Expiratory Flow (PEF) in Morning baseline and 52 weeks Change in AM PEF from baseline (mean over the 2 weeks run-in) to the average of the randomized treatment period.
Forced Expiratory Volume in One Second (FEV1) baseline and 52 weeks Change in pre-dose FEV1 from baseline (end of run-in, visit 3) to the average of the randomized treatment period
Asthma Treatment Satisfaction Measure (ATSM) Baseline and 52 weeks Overall score - change from baseline to end of treatment. For 11 individual attributes, expectations were subtracted from the outcomes. This difference and the importance rating were combined in a weighted average which was then multiplied by the raw satisfaction measure. The final derived satisfaction measure was transformed to a 0 to 100 scale, with higher scores representing greater satisfaction.
