Masking: Open Label
Primary Purpose: Treatment
Official Title: A Comparison of Symbicort® Single Inhaler Therapy (Symbicort Turbuhaler® 160/4.5mg, 1 Inhalation Two Times a Day (b.i.d.) Plus as Needed) and Conventional Best Practice for the Treatment of Persistent Asthma in Adults a -26-week, Randomized, Open-label, Parallel-group, Multicentre Study

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Time to First Severe Asthma Exacerbation [ Time Frame: 26 weeks ]
    Time to severe exacerbation among patients

Secondary Outcome Measures:
  • Number of Severe Asthma Exacerbations [ Time Frame: 26 weeks ]
    Total number of severe asthma exacerbations per treatment group

  • Change in Standardised Asthma Quality of Life Questionnaire (AQLQ(S)) Score [ Time Frame: Baseline and 26 weeks ]
    Quality-of-Life assessment; grouped in four domains;activity limitation, symptoms, emotional function and exposure to environmental stimuli, using with a scale from 1 to 7 where 1 represents the greatest possible impairment and 7 represents the least impairment.

  • Mean Use of As-needed Medication Per Day During Treatment Period [ Time Frame: Daily recording during the treatment period of 26 weeks ]
    Mean use of as-needed medication per day during treatment period
