Summary

This Phase 2b study tests camlipixant, an experimental drug, in 420 adults with moderate-to-severe irritable bowel syndrome (IBS) with diarrhea or mixed bowel habits. Participants receive either camlipixant or a placebo for 26 weeks. The main goal is to see if the drug reduces weekly abdominal pain. The trial also tracks other symptoms like bloating and discomfort.

What this could mean

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

Active substance
camlipixant
What this could lead to
If successful, camlipixant could offer a new treatment option to reduce abdominal pain and other symptoms in people with moderate-to-severe IBS-D and IBS-M.
What could go wrong
This is an early Phase 2b trial, so results may not confirm effectiveness. The drug may cause side effects, and not all participants may benefit. Larger studies are needed before it becomes available.
