New scan could spot prostate cancer spread better than current test
NCT ID NCT07635524
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
