Clinical Trial Summary

The purpose of this study is to establish the efficacy, safety and tolerability of barzolvolimab in adult participants with Chronic Spontaneous Urticaria (CSU) inadequately controlled by non-sedating second generation H1-antihistamines in comparison to placebo.


Clinical Trial Description

This is a global, multicenter, randomized, double-blind, parallel group, placebo-controlled phase 3 study investigating the efficacy, safety and tolerability of barzolvolimab in adult participants with Chronic Spontaneous Urticaria (CSU) who are symptomatic despite treatment with non-sedating second generation H1-antihistamines at 1-4 times the locally approved dose. There is a screening period of up to 4 weeks, followed by a 24-week placebo-controlled treatment period, a 28-week active treatment period where all participants receive barzolvolimab followed by a 16-week treatment free period. Approximately 915 adult participants (610 in the active arms and 305 in the placebo arm) will be randomly assigned to the treatment arms. ;
