Summary

This study tests three doses of tenapanor (5, 25, or 50 mg twice daily) against a placebo in 692 adults with chronic idiopathic constipation. Over 26 weeks, researchers will check if the drug increases complete spontaneous bowel movements. The goal is to find a safe, effective option for people with this condition.

What this could mean

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

Active substance: tenapanor
What this could lead to: If it works, this could provide a new daily medication option for people with chronic constipation who haven't found relief.
What could go wrong: This is a Phase 3 trial, but the drug may not work better than placebo, or side effects could limit its use. Results are not yet known.
