Primary

MeasureTime frameDescription
Trough (AM Pre-dose and Pre-rescue Bronchodilator) Forced Expiratory Volume in 1 Second (FEV1) at the End of the 6-week Treatment PeriodEnd of Week 6FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 was measured electronically using spirometry, prior to study medication and any rescue albuterol (bronchodilator) use. At the end of the 6-week treatment period, FEV1 was measured approximately 24 hours after the participant's last morning dose of study medication and approximately 12 hours after the evening dose of study medication. Trough FEV1 was analyzed using mixed effect analysis of covariance (ANCOVA) model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effect of participant. Intent-to-Treat Population is defined as all participants who were randomized and received at least one dose of study drug.

PEF was measured every morning and evening prior to study medication dose and any rescue albuterol (bronchodilator) use. Participants recorded PEF in a daily eDiary. Daily average of morning and evening PEF was averaged over the last 3 weeks of the 6-week treatment period, and analyzed using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant. This outcome measure explored the efficacy between GSK2190915 and montelukast due to the dosing time difference.
Daily Asthma Symptom Score Averaged Over the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6Daytime and night time asthma symptoms were recorded every evening at bedtime and every morning upon rising, respectively, before taking any rescue or study medication and before assessing the PEF. Symptoms were recorded on scales ranging from '0' (implying no symptoms) to either 5 (for daytime symptoms) or 4 (for night time symptoms) (implying severe symptoms). Participants recorded the symptoms in a daily eDiary. 24-hour period asthma symptom scores were averaged over the last 3 weeks of the 6-week treatment period, and analyzed using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.
Daily Rescue Short-acting beta2-agonist (SABA) Use Averaged Over the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6A SABA (albuterol) was provided to participants as a rescue medication, to use as needed for symptomatic relief of asthma symptoms. Participants were required to record their albuterol use in the morning and in the evening. Participants recorded the number of inhalations of rescue medication in a daily eDiary. The daily rescue SABA use was averaged over the last 3 weeks of the 6-week treatment period, and analyzed using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.
Percentage of Symptom-free Days During the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6Daytime asthma symptoms were recorded every evening at bedtime, before taking any rescue or study medication and before assessing the PEF. Symptoms were recorded on a 6-point scale ranging from '0' (implying no symptoms) to 5 (implying severe symptoms). Participants recorded the symptoms in a daily eDiary. The number of days when symptoms were not experienced (symptom-free days) during the last 3 weeks of the 6-week treatment period were counted, and percentage calculated by dividing by 21 and multiplying by 100. Analysis was done using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.
Daily Trough (Morning Pre-dose and Pre-rescue Bronchodilator) Morning Peak Expiratory Flow (PEF) Averaged Over the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6The PEF is a measure of lung function and measures how fast a person can breathe out. Trough PEF was measured every morning prior to study medication dose and any rescue albuterol (bronchodilator) use. Participants recorded PEF in a daily electronic diary (eDiary). Daily trough morning PEF was averaged over the last 3 weeks of the 6-week treatment period, and analyzed using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.
Percentage of Rescue-free Days During the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6Albuterol was provided as a rescue medication, and participants were required to record rescue medication use in the morning and in the evening.

Percentage of Nights Without Awakenings Due to Asthma During the Last 3 Weeks of the 6-week Treatment PeriodWeek 4 to Week 6Night time asthma symptoms were recorded every morning upon rising, before taking any rescue or study medication and before assessing the PEF. Symptoms were recorded on a 5-point scale: 0 = no symptoms during the night, 1 = symptoms causing to wake once, 2 = symptoms causing to wake twice or more, 3 = symptoms causing to be awake most of the night, 4 = could not sleep due to severe symptoms. Participants recorded the symptoms in a daily eDiary. The number of nights with no awakenings due to asthma during the last 3 weeks of the 6-week treatment period were counted, and percentage calculated by dividing by 21 and multiplying by 100.

Percentage of Nights Without Awakenings Due to Asthma During the Last 3 Weeks of the 6-week Treatment Period

Night time asthma symptoms were recorded every morning upon rising, before taking any rescue or study medication and before assessing the PEF. Symptoms were recorded on a 5-point scale: 0 = no symptoms during the night, 1 = symptoms causing to wake once, 2 = symptoms causing to wake twice or more, 3 = symptoms causing to be awake most of the night, 4 = could not sleep due to severe symptoms. Participants recorded the symptoms in a daily eDiary. The number of nights with no awakenings due to asthma during the last 3 weeks of the 6-week treatment period were counted, and percentage calculated by dividing by 21 and multiplying by 100. Analysis was done using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.

Time frame: Week 4 to Week 6

Population: ITT Population. Only those participants available at the specified time point were analyzed.

Percentage of Rescue-free Days During the Last 3 Weeks of the 6-week Treatment Period

Albuterol was provided as a rescue medication, and participants were required to record rescue medication use in the morning and in the evening. Participants recorded the number of inhalations of rescue medication in a daily eDiary. The number of days when rescue medication was not used (rescue-free days) during the last 3 weeks of the 6-week treatment period were counted, and percentage calculated by dividing by 21 and multiplying by 100. Analysis was done using mixed effect ANCOVA model for treatment effects, incorporating fixed effects of baseline, period, age, center, smoking status, and random effects of participant.

Percentage of Symptom-free Days During the Last 3 Weeks of the 6-week Treatment Period

Daytime asthma symptoms were recorded every evening at bedtime, before taking any rescue or study medication and before assessing the PEF. Symptoms were recorded on a 6-point scale ranging from '0' (implying no symptoms) to 5 (implying severe symptoms). Participants recorded the symptoms in a daily eDiary. The number of days when symptoms were not experienced (symptom-free days) during the last 3 weeks of the 6-week treatment period were counted, and percentage calculated by dividing by 21 and multiplying by 100.
