NCT ID NCT07635524

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 This study
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 Results may not be published yet.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

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 phase 2 trial tests whether a new radioactive imaging agent, 61Cu-NU101, can detect prostate cancer spread as well as or better than the current standard, Pylarify. 34 men with confirmed prostate cancer and visible disease on a prior Pylarify scan will receive one dose of 61Cu-NU101 followed by PET/CT imaging. The study compares the two scans to see if the new agent finds more or different cancer spots.

What this could mean

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

Active substance
61Cu-NU101 (a radioactive imaging agent)
What this could lead to
If successful, this could provide a new, equally effective or better imaging option for detecting prostate cancer spread.
What could go wrong
This is a small, early-phase study (34 people) comparing two scans, not a treatment. It may not show a meaningful improvement over the current standard.
