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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares a new imaging tracer, 68Ga-NODAGA-RGD, with standard methods (FDG-PET, MRI, ultrasound) to detect inflamed plaques in the carotid arteries. Twenty people scheduled for plaque-removal surgery will receive the tracer and undergo scans. The goal is to see which technique best identifies unstable, inflammation-prone plaques, using tissue analysis after surgery as the gold standard.

What this could mean

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

Active substance
68Ga-NODAGA-RGD, a radioactive tracer for PET/CT imaging
What this could lead to
If successful, this imaging method could help identify dangerous artery plaques earlier, potentially preventing strokes.
What could go wrong
This is a small, early-phase study focused on imaging accuracy, not treatment. The tracer may not prove superior to existing methods.
