detailed description
The purpose of this Phase 3, randomized, double-blind, placebo-controlled study is to assess the activity and safety of barzolvolimab compared to placebo in participants with cold induced urticaria (ColdU) or symptomatic dermographism (SD) who remain symptomatic despite the use of H1-antihistamines.
There is a Screening Period of up to 4 weeks, followed by a 24-week treatment period where patients will receive barzolvolimab or placebo. Patients receiving barzolvolimab will receive 450mg at the start of the treatment period and then 150mg every 4 weeks. Then there is a 28-week treatment period where all patients will receive 300mg barzolvolimab every 8 weeks, followed by a 16-week follow-up period where all patients are observed.
