New scan could reveal where cancer drugs go in the body

NCT ID NCT07221825

First seen Jun 25, 2026 · Last updated Jul 22, 2026 · Updated 3 times

Summary

This study tests a new imaging technique called low-count quantitative SPECT (LC-QSPECT) to see how the drug Radium-223 spreads in men with advanced prostate cancer. About 38 men who are already eligible for Radium-223 will get extra scans after their treatment. The goal is to see if this scan can reliably measure drug uptake in tumors and organs, which could help doctors personalize treatment in the future.

What this could mean

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

Active substance
Low-count quantitative single-photon emission computed tomography (LC-QSPECT) imaging
What this could lead to
If successful, this imaging method could help doctors see where Radium-223 goes in the body, potentially leading to better personalized treatment for prostate cancer.
What could go wrong
This is a very early feasibility study with only 38 participants. The imaging technique is new and may not provide clear enough results to change practice.
