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 Results may not be published yet.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
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 This study
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

Summary

This expanded access program offers patients with primary hyperparathyroidism a special PET scan using a radioactive tracer called 18F-fluorocholine. The scan helps doctors locate parathyroid adenomas—small, benign tumors that cause high calcium levels. By finding these tumors more accurately, surgeons can remove them more effectively. The program is available to patients aged 13 and older who meet eligibility criteria.

What this could mean

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

Active substance
18F-fluorocholine (FCH)
What this could lead to
If successful, this imaging technique could help doctors precisely locate parathyroid adenomas, guiding surgery and improving outcomes.
What could go wrong
This is an expanded access program, not a formal trial, so evidence is limited. The imaging may not detect all adenomas, and results may not apply to all patients.
