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 This study
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 Results may not be published yet.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

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.

Summary

This study is testing whether a special PET/CT scan using gallium-68 citrate can more accurately diagnose infections in artificial heart valves. Researchers will compare the scan results with the standard diagnosis after 3 months. The study involves 40 adults with suspected valve infections.

What this could mean

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

Active substance
Gallium-68 citrate (a radioactive tracer used in PET/CT imaging)
What this could lead to
If successful, this could provide a more accurate, non-invasive way to diagnose infections in artificial heart valves, potentially leading to faster and more targeted treatment.
What could go wrong
This is a small, early-phase study with only 40 participants, so results may not apply to everyone. The scan may not be accurate enough to replace current diagnostic methods.
