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.
