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
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 This study
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 Results may not be published yet.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

This study looks at whether platelet activation in the blood is higher in people whose brain aneurysm has already burst compared to those with an unruptured aneurysm. Researchers will collect blood samples from 230 patients during treatment. The goal is to see if platelet activity could help predict rupture risk.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If this study finds a link, it could point toward new ways to predict which aneurysms might rupture.
What could go wrong
This is an observational study, not a treatment trial. It only looks for a connection, so it won't directly help patients yet.

This is an AI summary of the original study and may miss details. Read our disclaimer.
