What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
