New imaging agent could sharpen prostate cancer detection
NCT ID NCT06101927
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 1 study tested a new radioactive tracer called [99mTc]Tc-BQ0413 in 10 men with prostate cancer. The tracer was injected once, and SPECT scans were taken over 24 hours to see where it goes in the body and how safe it is. The goal is to develop a better imaging tool for prostate cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Technetium-99m BQ0413 ([99mTc]Tc-BQ0413) - a radioactive tracer for imaging
- What this could lead to
- If successful, this could lead to a new imaging method to better detect and monitor prostate cancer using SPECT scans.
- What could go wrong
- This is a very early Phase 1 study with only 10 participants, so results may not apply broadly. The tracer's imaging accuracy compared to standard methods is still unknown.
