Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the clinical effect, the pharmacodynamics, the safety, and the pharmacokinetics of barzolvolimab (CDX-0159) in patients with Chronic Spontaneous Urticaria

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to assess the clinical effect, the pharmacodynamics, the safety, and the pharmacokinetics of barzolvolimab in patients with Chronic Spontaneous Urticaria.

There is a screening period of up to 4 weeks, followed by a 16-week placebo-controlled treatment period (Placebo-Controlled Treatment Phase) where patients will receive either barzolvolimab at a dose level of 75mg, 150mg, or 300mg, or placebo, and then a 36-week treatment period where all patients will receive barzolvolimab. Patients who receive barzolvolimab 75mg or placebo in the placebo-controlled treatment phase will be re-randomized to receive either barzolvolimab 150mg or 300mg in the active treatment phase.
