A drug that may curb bleeding during fibroid surgery faces its first big test
NCT ID NCT07721623
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial tests whether a single injection of carbetocin, a longer-acting relative of oxytocin, can reduce blood loss in women undergoing open abdominal surgery to remove uterine fibroids. About 900 participants will be randomly assigned to receive carbetocin or a placebo, and doctors will compare changes in hemoglobin levels and the need for blood transfusions. If it works, carbetocin could offer a simple way to make fibroid surgery safer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a synthetic hormone drug called carbetocin, similar to oxytocin but longer-acting, given as an injection to help the uterus contract and reduce bleeding
- What this could lead to
- If effective, carbetocin could become a standard option to reduce blood loss and transfusion needs during fibroid removal surgery.
- What could go wrong
- This is an early-phase trial, so the drug may not prove more effective than current options. Possible risks include allergic reactions or side effects from the medication.
