Can a clotting factor stop bleeding in ECMO patients?
NCT ID NCT06118372
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests a single dose of a lab-made clotting protein (recombinant von Willebrand factor) in 12 adult patients on ECMO who have major bleeding. The goal is to see if the drug is safe and how it behaves in the body. If successful, it may lead to a new way to control bleeding in this high-risk group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Recombinant von Willebrand Factor (a lab-made blood clotting protein)
- What this could lead to
- If it works, this could point toward a treatment to control severe bleeding in ECMO patients, potentially reducing complications and improving survival.
- What could go wrong
- This is a very early, small phase I trial with only 12 participants, so results may not apply to all patients. The drug could cause serious side effects or fail to stop bleeding.
