Pre-assignment Details  
Arm/Group Title Placebo ELLIPTA Inhaler
Hide Arm/Group Description Participants received study placebo via ELLIPTA inhaler at Visit 1 (Day 1) for use with their current daily inhaled asthma medication(s) that were to be continued during the study. Participants were instructed to take one inhalation from the ELLIPTA inhaler once daily at the same time each day until Day 28. At Visit 2 (Day 28), participants completed Version A or B of the ELLIPTA Inhaler Questionnaire as per randomisation. Questionnaire A & B have the same questions and in the same order, they only differ with response sequence.

1.Primary Outcome
Title The Percentage of Participants With Asthma Who Rated the Use of the ELLIPTA Inhaler as Easy or Very Easy, Among Those Who Demonstrated Correct Use of the Inhaler at the End of the Study.
Hide Description Participants rated how easy it was to use the ELLIPTA inhaler, using a four-point Likert scale (1-very easy, 2-easy, 3-difficult, 4-very difficult). “Easy to use” was defined as the combination of an “easy” or “very easy” rating choice. The percentage was reported overall for the single treatment group along with a 95% confidence interval (CI) for the percentage calculated using the exact binomial distribution.
Time Frame Day 28
Hide Outcome Measure Data
Hide Analysis Population Description
Modified Intent-to-Treat (mITT) Population: all participants who were screened and received at least one dose of study treatment (placebo) and were randomised to receive the ELLIPTA inhaler ease of use questionnaire version A or B at Visit 2.
Arm/Group Title Placebo ELLIPTA Inhaler
Hide Arm/Group Description:
Participants received study placebo via ELLIPTA inhaler at Visit 1 (Day 1) for use with their current daily inhaled asthma medication(s) that were to be continued during the study. Participants were instructed to take one inhalation from the ELLIPTA inhaler once daily at the same time each day until Day 28. At Visit 2 (Day 28), participants completed Version A or B of the ELLIPTA Inhaler Questionnaire as per randomisation. Questionnaire A & B have the same questions and in the same order, they only differ with response sequence.

2.Secondary Outcome
Title The Percentage of Participants Who Rated the Ability to Tell How Many Doses Were Remaining in the ELLIPTA Inhaler as Easy or Very Easy at the End of the Study
Hide Description Participants rated how easy it was to determine how many doses were left in the ELLIPTA inhaler, using a four-point Likert scale (1-very easy, 2-easy, 3-difficult, 4-very difficult). “Easy to use” was defined as the combination of an “easy” or “very easy” rating choice. The percentage was reported overall for the single treatment group along with a 95% CI for the percentage calculated using the exact binomial distribution.

3.Secondary Outcome
Title The Percentage of Participants Who Demonstrated Correct Use of the ELLIPTA Inhaler at the End of the Study
Hide Description Participants’ ability to correctly use the ELLIPTA inhaler was assessed at Visit 2 using the Correct Use Checklist by an ELLIPTA trained health care professional. The percentage was reported overall for the single treatment group along with a 95% CI for the percentage calculated using the exact binomial distribution.
