Dataset from A Multi-center, Randomized, Double-blind, Active and Placebo-controlled Study to Investigate the Safety and Efficacy of Ligelizumab (QGE031) in the Treatment of Chronic Spontaneous Urticaria (CSU) in Adolescents and Adults Inadequately Controlled With H1-antihistamines

The purpose of this study was to establish safety and efficacy of ligelizumab in adolescent and adult subjects with Chronic Spontaneous Urticaria (CSU) who remain symptomatic despite standard of care treatment by demonstrating better efficacy over omalizumab and over placebo.The study population consisted of 1,072 male and female subjects aged ≥ 12 years who were diagnosed with CSU and who remained symptomatic despite the use of H1-antihistamines.This was a multi-center, randomized, double-blind, active- and placebo-controlled, parallel-group study. There was a screening period of up to 28 days, a 52 week double-blind treatment period, and a 12 week post-treatment follow-up period.
