Summary

This study tests an injection called JYB1904 in 180 adults with chronic spontaneous urticaria (hives and itching lasting over 6 weeks) that isn't well controlled by standard antihistamines. Participants receive either the drug or a placebo every 12 weeks for 48 weeks. The main goal is to see if the drug reduces hive activity and itching scores after 12 weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
JYB1904 injection
What this could lead to
If it works, this could provide a new treatment option for people with chronic hives that don't respond well to standard antihistamines.
What could go wrong
This is an early Phase 3 trial with only 180 participants, so results may not apply to everyone. The drug may not prove more effective than placebo, and side effects are still being studied.
