Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Change From Baseline to the End of the 8-Week Treatment Period in Trough Forced Expiratory Volume in One Second (FEV1)	Pulmonary function was measured by forced expiratory volume in one second, defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 is defined as the morning (AM) pre-dose and pre-rescue bronchodilator FEV1 at the clinic visit. Baseline was the pre-dose value obtained at Visit 3. Change from Baseline was calculated as the end of Week 8 value minus the Baseline value. Analysis of covariance (ANCOVA) model used for statistical analysis. ITT Population was comprised of all participant randomized to treatment who received at least one dose of double-blind study medication.	Baseline and Week 8
Secondary	Mean Change From Baseline in Daily Evening (PM) Peak Expiratory Flow (PEF) Averaged Over the 8-Week Treatment Period	Peak expiratory flow is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Change from Baseline was calculated as the value of the averaged PEF daily (pre-dose and pre-rescue bronchodilator) evening over the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants)	Baseline up to Week 8
Secondary	Mean Change From Baseline in Daily Trough AM PEF Averaged Over the 8-Week Treatment Period	The PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Trough AM PEF is defined as the AM pre-dose and pre-rescue bronchodilator at the clinic visit. Change from Baseline was calculated as the value of the averaged PEF daily (pre-dose and pre-rescue bronchodilator) AM over the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in the Percentage of Symptom-free Days Averaged Over the 8-Week Treatment Period	Asthma symptoms were recorded in a daily electronic diary (eDiary) by the participants every day in the evening at bedtime and before taking any rescue or study medication and before the assessment of the PEF measurement. Participant's responses to evening assessments indicated no symptoms were considered to be symptom free. For participants, the symptom free days were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged of symptom-free days during the 8-Week treatment period minus the Baseline value. Baseline was defined as the last 7 days prior to randomization of the participants.	Baseline up to Week 8
Secondary	Mean Change From Baseline in the Percentage of Symptom-free Nights Averaged Over the 8-Week Treatment Period	Asthma symptoms were recorded in a daily eDairy by the participants every day in the morning upon rising and before taking any rescue or study medication and before the assessment of the PEF measurement. Participant's responses to the morning assessments indicated no symptoms were considered to be symptom free. For participants, the symptom free nights were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged of symptom-free nights during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in the Percentage of Rescue-free Days Averaged Over the 8-Week Treatment Period	The number of inhalations of rescue salbutamol/albuterol inhalation aerosol used during the day and night was recorded by the participants in an eDiary. The time span during which the participants did not have to take any rescue medication (medication intended to relieve symptoms immediately) was considered to be a rescue-free period. For participants, the rescue-free days were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged of rescue-free days during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in the Percentage of Rescue-free Nights Averaged Over the 8-Week Treatment Period	The number of inhalations of rescue salbutamol/albuterol inhalation aerosol used during the day and night was recorded by the participants in an eDiary. The time span during which the participants did not have to take any rescue medication (medication intended to relieve symptoms immediately) was considered to be a rescue-free period. For participants, the rescue-free nights were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged of rescue-free nights during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in Day-time Asthma Symptom Score Over the 8-Week Treatment Period	Participants recorded their day-time asthma symptom score in an eDiary each PM at bedtime and before taking any rescue or study medication and before assessing the PEF measurement during the 8-Week treatment period. Day-time asthma symptom scores, as: 0=no asthma symptoms, 1=one episode of short-time asthma symptoms, 2=two or more episodes of short-time asthma symptoms, 3=asthma symptoms occurring during most part of daytime without interference with daily life activities, 4=asthma symptoms occurring during most part of daytime with interference with daily life activities, 5=severe asthma symptoms that disable working or perform normal daily activities. Change from Baseline was calculated as the averaged of day-time asthma symptom score during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in Night-time Asthma Symptom Score Over the 8-Week Treatment Period	Participants recorded their night-time asthma symptom score in an eDiary each AM upon rising and before taking any rescue or study medication and before assessing the PEF measurement during the 8-Week treatment period. Night-time asthma symptom scores, as: 0=no asthma symptoms, 1= one awakening or waking early due to asthma symptoms, 2= two or more awakenings due to asthma symptoms (including waking early), 3= asthma symptoms almost prevented the participant from sleeping, 4= severe asthma symptoms completely prevented from sleeping. Change from Baseline was calculated as the averaged of night-time asthma symptom score during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Mean Change From Baseline in Day-time Rescue Short Acting beta2-agonist (SABA) Usage Over the 8-Week Treatment Period	The number of inhalations of rescue SABA, salbutamol/albuterol inhalation aerosol used during the day and night was recorded by the participants in an eDiary. Participants who used salbutamol/albuterol inhalation aerosol at day-time were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged number of day-time salbutamol/albuterol inhalation aerosol used during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week
Secondary	Mean Change From Baseline in Night-time Rescue SABA Usage Over the 8-Week Treatment Period	The numbers of inhalations of rescue SABA, salbutamol/albuterol inhalation aerosol used during the day and night was recorded by the participants in an eDiary. Participants who used salbutamol/albuterol inhalation aerosol at night-time were assessed during the 8-Week treatment period. Change from Baseline was calculated as the averaged number of night-time salbutamol/albuterol inhalation aerosol used during the 8-Week treatment period minus the Baseline value (defined as the last 7 days prior to randomization of the participants).	Baseline up to Week 8
Secondary	Number of Participants Who Withdrew Due to Lack of Efficacy During the 8-Week Treatment Period	The participants who met any of the following withdrawal criteria were considered to be withdrawn due to lack of efficacy: 1) Clinic FEV1 below stability limit calculated at Visit 3. 2) More than three days between two consecutive visits, PEF has fallen below stability limit calculated at Visit 3. 3) Use of 12 or more inhalations of SABA per day for more than two days between consecutive visits. 4) Asthma exacerbation defined as worsening requiring any treatment other than study medication or rescue medication. This included requiring the use of systemic or inhaled corticosteroids and /or emergency room visit or hospitalization for the treatment of asthma. The stability limit was calculated as best pre-salbutamol/albuterol FEV1 at Visit 3 x 80 percent (%).	Upto 8 Weeks
