New imaging agent aims to spot hidden immune cells in tumors
NCT ID NCT04168528
First seen Jun 04, 2026 · Last updated Jun 23, 2026 · Updated 3 times
Summary
This early-phase trial tested a radioactive imaging agent called 68GaNOTA-Anti-MMR-VHH2 to see if it could safely highlight tumor-associated macrophages on PET/CT scans in people with breast cancer or melanoma. The study planned to enroll 13 adults with solid tumors, but it was terminated early. The goal was to assess safety, how the agent spreads in the body, and whether it could help visualize tumors.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
68GaNOTA-Anti-MMR-VHH2 (a radioactive imaging agent injected before a PET/CT scan)
What this could lead to
If successful, this could provide a new way to see certain immune cells around tumors, potentially helping doctors better understand and monitor cancers.
What could go wrong
This was a very early, small trial that was terminated, so results are limited. The imaging agent may not reliably highlight tumors or may cause unexpected side effects.
Conditions
