What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether a fresh human placenta can be used as a realistic model for training neurosurgeons to repair brain aneurysms. The placenta's blood vessels closely resemble those in the brain, and researchers will create artificial aneurysms using a small catheter. The goal is to improve surgical skills without risking patient safety.

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 successful, this training model could help neurosurgeons practice complex aneurysm surgeries safely, potentially improving patient outcomes.
What could go wrong
This is a small, early-stage training study with 50 participants, focused on skill assessment rather than patient treatment. Results may not translate to real-world surgical success.
