Could a single injection fix bowel leakage after childbirth? new trial aims to find out
NCT ID NCT05776277
First seen Jun 25, 2026 · Last updated Jul 22, 2026 · Updated 3 times
Summary
This Phase 3 trial tests a single injection of muscle cells (iltamiocel) into the anal sphincter to reduce accidental bowel leakage in women who have had a childbirth injury. About 200 women will receive either the cell injection or a placebo. The study measures how often leakage episodes occur over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- iltamiocel (muscle cells injected into the anal sphincter)
- What this could lead to
- If it works, this could offer a new, non-surgical treatment to reduce accidental bowel leakage in women who have had a childbirth injury.
- What could go wrong
- This is a Phase 3 trial, but it is still experimental. The treatment may not work better than placebo, and there are risks from the injection procedure, such as infection or pain.
