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 Results may not be published yet.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.
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.

Summary

This study looks at whether taking a small piece of ligament during routine carpal tunnel surgery can help diagnose transthyretin amyloidosis, a serious condition that often goes unnoticed until it affects the heart. Researchers will compare this new biopsy method to the standard one in 500 adults. If successful, it could make early detection easier and safer.

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 this works, it could offer a simpler, safer way to spot early signs of transthyretin amyloidosis during routine carpal tunnel surgery, allowing for earlier treatment.
What could go wrong
This is a diagnostic study, not a treatment trial. The ligament biopsy may not match the accuracy of the current gold standard, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.

The number the study aims to enrol. It can still change while the study runs.

Started

May 2026

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
