A 12-week, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Assess the Efficacy and Safety of QAW039 When Added to Standard-of-care Asthma Therapy in Patients With Uncontrolled Asthma


About this study

A randomized, multicenter, double-blind, placebo- controlled parallel-group study to determine the efficacy and safety of QAW039, compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult and adolescent (≥ 12 years) patients with uncontrolled asthma with respect to change from baseline in forced expiratory volume in 1 second (FEV1) at the end of 12 weeks of treatment.
