Steroids In Eosinophil Negative Asthma

Because approximately half of all mild-moderately-severe asthma is persistently non-eosinophilic, it is important to determine prospectively if patients who are persistently non-eosinophilic differ in their benefit from inhaled corticosteroid treatment compared to patients who are not persistently non-eosinophilic.

SIENA is a 42-week randomized, stratified, 3-period double-blind placebo-controlled crossover study of patients with symptomatic mild-to-moderate asthma, not already taking an inhaled corticosteroid, in whom the effect of "medium-dose" inhaled corticosteroid (ICS) will be compared with the effect of placebo and with a long-acting muscarinic antagonist (LMA).
