Can a common drug stop brain bleeds? major trial launches
NCT ID NCT05836831
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This large, phase 4 trial tests whether tranexamic acid, a drug that helps blood clot, can improve outcomes for people with a bleeding stroke. About 3400 adults will receive either the drug or standard care within 4.5 hours of symptoms. The main goal is to see if it reduces deaths at 30 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tranexamic acid
- What this could lead to
- If it works, this could provide a simple, widely available treatment to reduce bleeding and improve survival after a hemorrhagic stroke.
- What could go wrong
- This is a large trial, but earlier studies on tranexamic acid for brain bleeds have shown mixed results. The drug may not meaningfully improve outcomes and could increase the risk of blood clots.
