New drug 610 aims to tame severe asthma attacks
NCT ID NCT06323213
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 3 trial tests a new drug called 610 in 480 Chinese adults with severe eosinophilic asthma, a type of asthma linked to high levels of certain white blood cells. Participants receive either 610 or a placebo injection for 52 weeks. The main goal is to see if 610 reduces the number of severe asthma attacks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 610 (a drug injected under the skin)
- What this could lead to
- If it works, this could offer a new treatment option to reduce severe asthma attacks for people with hard-to-control eosinophilic asthma.
- What could go wrong
- This is a Phase 3 trial, but it's still experimental. The drug may not work better than placebo, and side effects are possible. Results may only apply to Chinese adults.
