This was a multi-centre, randomised, placebo-controlled, double blind, 3-arm study designed to compare the efficacy and safety of a once daily dose of QAW039 with placebo in non-atopic and atopic asthmatics both inadequately controlled despite receiving a low dose ICS background therapy, over a 12 week treatment period. Efficacy and safety of a once daily dose of QAW039 was also compared with an increased dose of ICS in atopic asthmatics taking low dose ICS as background therapy.
The purpose of the study was to assess the clinical effect of QAW039 in non-atopic asthmatics taking low dose Inhaled Corticosteroid (ICS) as background therapy.
