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 Results may not be published yet.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

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.

Summary

This trial explores whether specially trained dogs can identify high-risk prostate cancer by smelling urine samples. Men with suspected prostate cancer will provide urine samples, which six dogs will sniff. The study will compare the dogs' accuracy against MRI results and biopsy findings to see if canine detection could serve as a reliable, non-invasive diagnostic tool.

What this could mean

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

Active substance
canine detection of urine samples
What this could lead to
If successful, this could lead to a non-invasive, dog-based screening method to help decide when biopsies are needed, reducing unnecessary procedures.
What could go wrong
The trial is relatively small and early-stage. Dog performance may vary, and results may not generalize to broader populations or clinical settings.
