New radioactive tracer could spot hidden cancers

NCT ID NCT05940298

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed phase 1 trial tested a radioactive imaging agent called [99mTc]Tc-DB8 in 10 people with prostate or breast cancer. The goal was to see how the agent spreads in the body and whether it can help detect tumors using SPECT scans. Researchers also checked for safety and compared the images to standard scans like CT or MRI.

What this could mean

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

Active substance

[99mTc]Tc-DB8 (a radioactive imaging agent)

What this could lead to

If successful, this could lead to a new way to detect prostate and breast cancer tumors using SPECT imaging, potentially improving diagnosis.

What could go wrong

This is a very early, small study (10 people) that only looks at imaging, not treatment. The agent may not clearly show tumors or could have safety issues.
