Brief summary

This study is a randomized, double-blind, double-dummy, parallel group, multicenter, non-inferiority study. The study will enroll adult and adolescent asthmatic subjects who are currently receiving mid dose inhaled corticosteroids (ICS) plus long-acting beta2-agonist (LABA) (equivalent to fluticasone propionate \[FP\]/salmeterol 250/50 microgram \[mcg\]twice daily \[BD\]), either via a fixed dose combination product or through separate inhalers. The study consists of a LABA washout period of 5 days and a run-in period of 4 weeks, followed by a treatment period of 24 weeks, and a follow up contact period of one week. The total duration of the study is 30 weeks. Approximately 1461 subjects will be randomized to one of the following three treatments (487 per treatment): fluticasone furoate (FF)/vilanterol (VI) 100/25 mcg once daily (OD) in the evening (PM) via ELLIPTA™ inhaler plus placebo BD via ACCUHALER™/DISKUS™; FP/salmeterol 250/50 mcg BD via ACCUHALER/DISKUS inhaler plus placebo OD (PM) via ELLIPTA inhaler; FP 250 mcg BD via ACCUHALER/DISKUS inhaler plus placebo OD (PM) via ELLIPTA inhaler. In addition, all subjects will be supplied with albuterol/salbutamol inhalation aerosol to use as needed to treat acute asthma symptoms. This study will determine if FF/VI 100/25 mcg OD via ELLIPTA inhaler is non-inferior to FP/salmeterol 250/50 mcg BD via ACCUHALER/DISKUS inhaler in adult and adolescent asthmatic subjects already adequately controlled on a twice-daily ICS/LABA.

MeasureTime frameDescription
Change From Baseline in Evening (Post Meridiem [PM]) Forced Expiratory Volume in One Second (FEV1) Using Intent-to-Treat (ITT) PopulationBaseline and Week 24FEV1 was defined as the volume of air that can be forced out in one second after taking a deep breath. FEV1 (pre-bronchodilator and pre-dose) was measured at Baseline up to Week 24 at evening using spirometry. Repeated Measures analysis was adjusted for Baseline, region, sex, age, treatment, visit, visit by Baseline interaction and visit by treatment interaction. Visit 3 values were taken as Baseline value and change from Baseline was defined as the difference between the value of the endpoint at the time point of interest and the Baseline value. Statistical analysis was performed using the mixed model repeated measures (MMRM) model and least square mean and standard error were calculated. The analysis was performed on ITT Population which comprised of all participants randomized to treatment and who received at least one dose of study medication.

MeasureTime frameDescription
Change From Baseline in Morning (Ante Meridiem [AM]) Peak Expiratory Flow (PEF)Baseline and Weeks 1-24PEF was measured using an electric flow meter each morning. Change from Baseline (defined as the last 7 days prior to randomization of the participants) was calculated as the value of the averaged daily AM PEF over the 24-week treatment period minus the Baseline value. Statistical analysis was performed using an ANCOVA model with covariates of Baseline, region, sex, age and treatment and least square mean and standard error were calculated.
Change From Baseline in the Percentage of Rescue-free 24-hour PeriodsBaseline and Weeks 1-24The number of inhalations of rescue medication used during the day and night were recorded by participants using an electronic diary (e-diary). A 24-hour (hr) period in which a participant's responses to both the morning and evening assessments indicated no use of rescue medication was considered to be rescue free. The Baseline value was derived from the last 7 days of the daily eDiary prior to the randomization of the participant. Change from Baseline was calculated as the averaged value during the 24-week treatment period minus the Baseline value. Statistical analysis was performed using an Analysis of Covariance (ANCOVA) model with covariates of Baseline, region, sex, age and treatment and least square mean and standard error were calculated.
Change From Baseline in PM PEFBaseline and Weeks 1-24PEF was measured using an electric flow meter each evening. Change from Baseline (defined as the last 7 days prior to randomization of the participants) was calculated as the value of the averaged daily PM PEF over the 24-week treatment period minus the Baseline value. Statistical analysis was performed using an ANCOVA model with covariates of Baseline, region, sex, age and treatment and least square mean and standard error were calculated.
Percentage of Participants With Asthma Control Test (ACT) Score Greater Than or Equal to 20Week 24The ACT was a five-item questionnaire developed as a measure of participant's asthma control. The percentage of participants controlled, defined as having ACT score greater than or equal to 20 at the end of Week 24 were analyzed using logistic regression model with covariates of Baseline ACT score, region, sex, age and treatment group.
Change From Baseline in the Percentage of Symptom-free 24-hour PeriodsBaseline and Weeks 1-24Change from Baseline in the percentage of symptom-free 24 hour period was evaluated. A 24-hour (hr) period in which a participant's responses to both the morning and evening assessments indicated no symptoms was considered to be symptom free. The Baseline value was derived from the last 7 days of the daily eDiary prior to the randomization of the participant. Change from Baseline was calculated as the averaged value during the 24-week treatment period minus the Baseline value.Statistical analysis was performed using an ANCOVA model with covariates of Baseline, region, sex, age and treatment and least square mean and standard error were calculated.
