Summary

This study tests an injected drug called brenipatide in 342 adults with irritable bowel syndrome with constipation (IBS-C). Participants will receive either the drug or a placebo for about 35 weeks. The goal is to see if brenipatide safely reduces abdominal pain and improves bowel habits better than a dummy shot.

What this could mean

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

Active substance
brenipatide (a drug injected under the skin)
What this could lead to
If it works, this could lead to a new treatment option that eases abdominal pain and improves bowel movements for people with IBS-C.
What could go wrong
This is an early Phase 2 trial, so the drug may not prove more effective than placebo. Side effects are still being studied, and results may not apply to all IBS-C patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
