New pill could tame stubborn hives
NCT ID NCT07005713
First seen Jun 25, 2026 · Last updated Sep 10, 2026 · Updated 3 times
Summary
This early-stage trial tested an experimental oral drug called BGB-16673 in 34 adults with chronic spontaneous urticaria (CSU), a condition causing persistent hives and itching. The study was double-blind and placebo-controlled, meaning neither patients nor doctors knew who got the real drug. The main goals were to check safety and how the drug moves through the body, not yet to prove it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BGB-16673 (an oral drug)
- What this could lead to
- If successful, this could lead to a new oral treatment option for people with chronic hives that are not controlled by antihistamines.
- What could go wrong
- This is a very early Phase 1b trial with only 34 participants, focused on safety and dosing. It is too small and early to know if the drug will effectively reduce hives or be safe long-term.
