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 Results may not be published yet.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
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

Researchers test whether a camera called Fluobeam helps surgeons locate parathyroid glands faster during surgery for mild primary hyperparathyroidism. The trial enrolls adults with this condition who need surgery. Half the participants undergo surgery with the camera, and half without it. The main goal is to see if the camera shortens surgery time and improves recovery of normal calcium levels.

What this could mean

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

Active substance
Fluobeam, a camera that uses fluorescent light to help surgeons see parathyroid glands during surgery
What this could lead to
If it works, surgeons could locate parathyroid glands faster and more accurately, potentially reducing surgery time and improving cure rates for mild primary hyperparathyroidism.
What could go wrong
The camera may not speed up surgery or improve outcomes compared to standard techniques. As a device study, it may not show clear benefits, and results might not apply to all patients or surgeons.
