Descripción detallada

This was a randomized, multicenter, multi-national, double-blind, placebo-controlled, parallel-arm study evaluating the effect of 5 dose levels of CSJ117 in adult subjects with inadequately controlled asthma despite medium to high dose inhaled corticosteroid (ICS) plus long-acting beta agonist (LABA). Subjects were assigned to one of the following six treatment arms/groups in a ratio of 2:1:1:1:2:2: * Placebo inhaled once daily * CSJ117 0.5 mg inhaled once daily * CSJ117 1.0 mg inhaled once daily * CSJ117 2.0 mg inhaled once daily * CSJ117 4.0 mg inhaled once daily * CSJ117 8.0 mg inhaled once daily The study included: * A screening period of approximately 2 weeks * A single blinded placebo run-in period of 4 weeks (extended to 8 weeks for subjects experiencing an asthma exacerbation or respiratory tract infection during the run-in period) * A double blinded treatment period of 12 weeks * A follow-up period of up to 12 weeks, study drug free, following the last dose of study treatment. Patients who successfully completed 12 weeks of treatment in this study could be offered participation in the Safety Extension Study CCSJ117A12201E1 (NCT04946318).
