Understanding urticaria
What exactly is chronic spontaneous urticaria (CSU)?
There are multiple forms of urticaria, but chronic spontaneous urticaria (CSU) is defined as hives that come and go unexpectedly, with their root cause unknown. These hives—or raised, red, itchy bumps or welts on the skin—cause discomfort in sufferers, and occur frequently (almost daily) for a duration of six weeks or more. They typically last between 30 minutes and 24 hours. Additionally, with CSU, hives may be big or small, occur anywhere on your body, the affected area may be warm to the touch, and in more severe cases, may cause swelling, headache, fatigue, joint pain, wheezing, diarrhea and/or rapid heartbeat.

How is it treated?
What We Hope To Do
More than 500,000 Americans are estimated to suffer from chronic urticaria. The spontaneous form is particularly frustrating, as what causes patients’ to break out in hives is unknown.2

What will happen during the study?
This study is randomized and double-blind, which means neither participants nor study staff will know whether participants receive the investigational treatment, EVO756, in varying dose levels, or a placebo, which contains no active medication. Participants will receive either the study drug or placebo in tablet form to take for 12 weeks and be evaluated on an out-patient basis. Total duration of participation for each subject is expected to be approximately 18 weeks, including up to 30 days for screening, the 12-week treatment window, and two subsequent weeks of follow-up.
