Summary
The efficacy of inhaled corticosteroids (ICS) in asthmatic subjects showing no sputum
eosinophils is controversial. The broad aim of this study is to assess whether ICS alone or
in combination with long-acting beta-2 agonists are an effective treatment in
non-eosinophilic asthmatic subjects. Methods: The investigators will perform a randomized
double-blind, placebo-controlled, multicenter study comparing the efficacy of ICS and placebo
for 4 weeks followed by a 4-week open treatment period with ICS/salmeterol in steroid-naïve
asthmatic subjects without sputum eosinophilia. The primary outcome will be the the Asthma
Control Questionnaire (ACQ) score after four weeks of treatment by ICS or placebo.
This study will determine whether or not non-eosinophilic asthmatic subjects respond to ICS
and if they further benefit from the addition of a long-acting beta-2 agonists. This study
will also determine whether or not the assessment of airway inflammation should be performed
in every asthmatic patient in order to give the most appropriate treatment.
