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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study explores whether a special PET/CT scan using a tracer called 68Ga-FAPI can detect fibrosis (scarring) in the kidneys of people with chronic kidney disease. Currently, scarring can only be confirmed through a kidney biopsy, which is invasive and can miss areas of damage. The researchers will compare the scan results with biopsy findings to see if the imaging method accurately reflects the amount of fibrosis. If it works, this could lead to a safer, more complete way to monitor kidney disease progression.

What this could mean

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

Active substance
68Ga-FAPI tracer for PET/CT imaging
What this could lead to
If successful, this imaging method could allow doctors to assess kidney scarring without an invasive biopsy, improving monitoring of chronic kidney disease.
What could go wrong
This is a small pilot study with only 30 participants, so results may not apply broadly. The tracer's accuracy in detecting fibrosis is still unproven.

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 30 people
