Brief Summary

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

This is a study to determine the safety of multiple doses of 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 the study is to explore the safety, pharmacodynamics, and pharmacokinetics of ascending doses of CDX-0159 in patients with Chronic Spontaneous Urticaria who remain symptomatic despite treatment with antihistamines.

There is a screening period of up to 2 weeks, a 12-week double-blind treatment period and a 12-week follow-up period after treatment. Patients will receive multiple doses of CDX-0159 or placebo as add on therapy to their antihistamine.
