Summary
"This trial aims to see if barzolvolimab is effective, safe, and well-tolerated in adults with Chronic Spontaneous Urticaria who have not responded well to common
Who is the study for?
Adults over 18 with chronic hives for at least 6 months, not relieved by standard antihistamines. They must have had symptoms for more than 6 weeks and be on a stable antihistamine regimen for at least 4 weeks. Participants need normal blood counts, liver function, agree to use contraception, and can manage a daily symptom diary.
What is being tested?
The trial is testing the effectiveness of barzolvolimab against placebo in adults with Chronic Spontaneous Urticaria (CSU) that's not controlled by second-generation non-sedating H1-antihistamines. It aims to determine if barzolvolimab can better manage their symptoms.
What are the potential side effects?
While specific side effects are not listed here, common reactions may include injection site discomfort, potential allergic reactions or immune system responses due to the nature of biologic treatments like barzolvolimab.
