New scan could reveal hidden cancer cells

NCT ID NCT05620472

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early study tested a radioactive imaging agent called [99mTc]Tc(CO)3-(HE)3-Ec1 in 10 adults with solid tumors. The agent is designed to attach to EpCAM receptors on cancer cells, making them visible on SPECT scans. Researchers aimed to see where the agent goes in the body, measure radiation exposure, and check safety. This is a diagnostic study, not a treatment.

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(CO)3-(HE)3-Ec1 (a radioactive imaging agent)

What this could lead to

If successful, this could lead to a new way to see certain cancer cells on scans, helping doctors diagnose or monitor tumors more precisely.

What could go wrong

This is a very small, early Phase 1 study with only 10 participants. It is designed to test safety and imaging, not treatment. The approach may not prove useful for routine care.
