NCT ID NCT05424783

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 This study
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 Results may not be published yet.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 giving men with low-risk prostate cancer two extra tests—a genomic test (GPS) and a special MRI—helps them stick with active surveillance (monitoring instead of immediate treatment). Researchers will track 222 men for 18 months to see if these tests improve safety and reduce unnecessary biopsies. The goal is to find the right balance between catching dangerous cancers and avoiding overtreatment.

What this could mean

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

Active substance
Genomic Prostate Score assay and multi-parametric MRI
What this could lead to
If successful, this could show that adding these tests helps men safely avoid or delay aggressive treatment, improving quality of life.
What could go wrong
This is an observational study, not a treatment trial. The tests may cause false alarms leading to unnecessary procedures, and results may not apply to all groups.
