Trial Outcomes & Findings for Should Non-eosinophilic Asthmatic Subjects be Treated With Inhaled Corticosteroids? (NCT NCT00509197)

NCT ID: NCT00509197

Last Updated: 2016-08-15

Results Overview

Validated questionnaire assessing asthma control after 4 weeks of treatment with ICS or placebo. The ACQ has 7 questions (the top scoring 5 symptoms, FEV1% pred. and daily rescue bronchodilator use). Patients are asked to recall how their asthma has been during the previous week and to respond to the symptom and bronchodilator use questions on a 7-point scale (0=no impairment, 6= maximum impairment). The ACQ score is the mean of 7 items and thus ranges between 0 (well controlled) and 6 (extremely poorly controlled) to yield a mean score out of 6. The higher the score, the worst asthma control is.

PRIMARY outcome

Timeframe: Four weeks

Population: Intention to treat

Validated questionnaire assessing asthma control after 4 weeks of treatment with ICS or placebo. The ACQ has 7 questions (the top scoring 5 symptoms, FEV1% pred. and daily rescue bronchodilator use). Patients are asked to recall how their asthma has been during the previous week and to respond to the symptom and bronchodilator use questions on a 7-point scale (0=no impairment, 6= maximum impairment). The ACQ score is the mean of 7 items and thus ranges between 0 (well controlled) and 6 (extremely poorly controlled) to yield a mean score out of 6. The higher the score, the worst asthma control is.

SECONDARY outcome

Timeframe: Four weeks

Validated questionnaire assessing quality of life related to asthma after 4 weeks of treatment. The AQLQ is composed of 32 questions in 4 domains (symptoms, activity limitation, emotional function and environmental stimuli). The activity domain contains 5 'patient-specific' questions. This allows patients to select 5 activities in which they are most limited and these activities will be assessed at each follow-up. Patients are asked to think about how they have been during the previous two weeks and to respond to each of the 32 questions on a 7-point scale (7 = not impaired at all - 1 = severely impaired). The AQLQ score is rated on a 7-point scale (1=maximal impairment, 7=no impairment) to yield a mean score out of 7. The worse the quality of life is , the lower the score is.
