Airway Hyper-responsiveness Study In Asthma Using Salmeterol/Fluticasone Propionate Combination Product
This double-blind, stratified, parallel group study is to determine whether aiming for 'Total control' results in better airway hyper-responsiveness than maintaining the treatment level at which 'Well-controlled' asthma was achieved. The primary endpoint is the mean change in PC20 methacholine. Well controlled subjects (as assessed after a 12 week run-in period) will enter a 24 week treatment period during which they will record PEF(Peak Expiratory Flow), symptoms, rescue beta2-agonist use over 24 hours, night time awakenings, asthma exacerbations, emergency visits due to asthma and Adverse Events. At every visit lung function measurements and airway hyper-responsiveness will be measured.
|Study Design:||Allocation: Randomized

|Official Title:||See Detailed Description|
- Mean change in PC20 methacholine (as a measure of airway hyper-responsiveness) following 24 weeks of treatment.
- Number of 'Totally-controlled' and Well-controlled patients at the end of the run-in and treatment period according to the GOAL criteria.
|Study Start Date:||November 2005|
Drug: Salmeterol/fluticasone propionate combination
A multi-centre, randomised, double blind, stratified, and parallel group study to evaluate whether a treatment strategy based on aiming for 'Total control' results in better airway hyper-responsiveness than a treatment strategy based on maintaining the treatment level at which 'Well-controlled' asthma was achieved.
