What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Mean Asthma Control Questionnaire (ACQ) Score at Day 92
Time Frame: Day 1 and 92
|
Asthma Control Questionnaire (ACQ) is a participant-reported questionnaire to assess the asthma control with 6 items assessing night-time waking, symptoms on waking, activity limitation, shortness of breath, wheeze, and rescue short-acting beta agonist use.
Each item was rated on a 7-point Likert scale ranging from 0 (no impairment) to 6 (maximum impairment).
Overall ACQ score is the mean of the 6 item scores with a score range of 0 (well controlled) to 6 (extremely poor controlled).
Data collected on Day 1 prior to dosing was considered as baseline.
Results were reported for overall ACQ score.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to First Observed Asthma Control
Time Frame: Day 1 to Day 92 and Day 169
|
Time to first asthma control was defined as the number of days from Study Day 1 to the post-baseline ACQ score measurement time point when greater than or equal to (>=) 0.5 reduction from baseline in mean ACQ score was first observed.
Time to first asthma control was analyzed from Day 1 through Day 92 and up to entire study duration through Day 169.
The ACQ score is a participant-reported questionnaire to assess the asthma control with 6 items assessing night-time waking, symptoms on waking, activity limitation, shortness of breath, wheeze, and rescue short-acting beta agonist use.
Each item was rated on a 7-point Likert scale ranging from 0 (no impairment) to 6 (maximum impairment).
Overall ACQ score is the mean of the 6 item scores with a score range of 0 (well controlled) to 6 (extremely poor controlled).
|
Day 1 to Day 92 and Day 169
|
Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Recorded at Study Sites at Day 1, 15, 29, 43, 57, 71, 85, 92, 127 and 169
Time Frame: Day 1, 15, 29, 43, 57, 71, 85, 92, 127 and 169
|
Forced Expiratory Volume in 1 Second (FEV1) is the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration.
Spirometry was performed with the participant in the sitting/standing (kept consistent at each visit) position at study sites by the investigator or qualified designee according to American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines.
Multiple forced expiratory efforts (at least 3 but no more than 8) were performed for each office spirometry session and the 2 best efforts that met ATS/ERS acceptability and reproducibility criteria were recorded.
The best efforts were based on the highest FEV1.
The maximum FEV1 of the 2 best efforts was used for the analysis.
Data collected on Day 1 prior to dosing was considered as baseline.
|
Day 1, 15, 29, 43, 57, 71, 85, 92, 127 and 169
|
Change From Baseline in Peak Expiratory Flow (PEF) Recorded at Home Every Week From Day 1 to 169
Time Frame: Day -7 to 1 (predose), Day 2 to 169
|
The PEF is a participant's maximum speed of expiration, as measured with a peak flow meter.
Home peak flow testing for PEF was performed every morning while sitting or standing prior to using any medication (if needed) for asthma.
Mean of the data was collected over 1 week prior to dosing on Day 1 was considered as baseline.
Mean PEF values for each week were used to calculate the change from baseline values starting from Day 2 to 169.
|
Day -7 to 1 (predose), Day 2 to 169
|
Number of Puffs of Rescue Beta-2 Agonist Per Week
Time Frame: Day -7 to 169
|
Number of Puffs of Rescue Beta-2 Agonist Per Week Rescue beta-2 agonist use (total number of puffs for the preceding week) was collected daily in the morning by the participants in the daily diary provided to them.
Average values for each week were reported starting from Day -7 to Day 169.

Time Frame: Day 1, 29, 57, 92, 127 and 169
|
Asthma Quality of Life Questionnaire (Standardized Version) (AQLQ[S]): a 32-item questionnaire that measures the functional impairments experienced by adult participants including 4 domains (Symptoms, Activity Limitations, Emotional Function, and Environmental Stimuli).
Participants were asked to recall their experiences during the previous 2 weeks and to score each of the 32 questions on a 7-point scale ranging from 7 (no impairment) to 1 (severe impairment).
The overall score was calculated as the mean response to all questions.
The 4 domain scores were the means of the responses to the questions in each of the domains.
Overall AQLQ score and 4 domain scores ranged from 7 (no impairment) to 1 (severe impairment).
