Can a stronger blood thinner protect the brain after a ruptured aneurysm?
NCT ID NCT07818083
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Researchers are testing whether adding tirofiban to standard antiplatelet therapy improves recovery for people whose ruptured brain aneurysm is repaired with a stent. The trial enrolls adults with acute subarachnoid hemorrhage who receive stent-assisted coiling within 72 hours of symptoms. Participants receive either tirofiban plus aspirin and clopidogrel, or aspirin and clopidogrel alone. The main goal is to see how many people have little or no disability 90 days later, and to track new strokes and bleeding risks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tirofiban, an antiplatelet drug given with aspirin and clopidogrel
- What this could lead to
- If it works, adding tirofiban could become a standard way to protect brain blood flow during stent-assisted aneurysm repair and improve recovery after a bleed.
- What could go wrong
- Tirofiban is a powerful blood thinner, so it may raise the risk of bleeding in the brain or elsewhere. The trial is still testing whether the benefit outweighs that risk, and results may not apply to all patients.
