New PET tracer aims to spot hidden cancers with precision

NCT ID NCT07172503

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study tests a new radioactive imaging agent called 68Ga-NOTA-GPA33 nanobody, which targets a protein (GPA33) found on some cancer cells. Researchers will use PET scans to see if this agent can better detect and stage colorectal, stomach, and pancreatic cancers in 56 patients and healthy volunteers. The goal is to improve diagnosis and staging compared to standard methods.

What this could mean

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

Active substance
68Ga-NOTA-GPA33 nanobody (a radioactive imaging agent)
What this could lead to
If successful, this could provide a more accurate way to detect and stage certain cancers using PET scans, potentially improving treatment decisions.
What could go wrong
This is an early diagnostic study with only 56 participants, so results may not apply to all patients. The imaging agent's accuracy and safety are still being evaluated.
