Awards & highlights

Summary

This trial will check the safety and effectiveness of a new drug for treating chronic hives in adults. It will also look at its pharmacological properties.

Who is the study for?

Adults over 18 with chronic spontaneous urticaria (CSU) who still have symptoms despite taking H1 antihistamines and omalizumab can join. They must not be pregnant, nursing, or planning pregnancy; should not have other active diseases mimicking CSU; no recent use of certain medications like JAK inhibitors; and willing to use contraception if applicable.

What is being tested?

The trial is testing Briquilimab's safety, how the body processes it, and its initial effectiveness in treating CSU compared to a placebo. It starts with an open-label phase where everyone gets Briquilimab, followed by a randomized double-blind phase where participants get either Briquilimab or a placebo without knowing which one.

What are the potential side effects?

Possible side effects of Briquilimab are not detailed here but may include reactions similar to other monoclonal antibodies such as infusion-related reactions, fatigue, headaches, potential allergic responses or impacts on immune function.
