New imaging technique targets Hard-to-Find cancers

NCT ID NCT05737615

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study aimed to test a new two-step PET imaging method to better detect cancers that produce a substance called CA19-9, such as pancreatic, bladder, and gastrointestinal tumors. The plan was to give patients an antibody followed by a radioactive tracer to highlight cancer cells. However, the trial was withdrawn before any patients were enrolled, so no data was collected.

Active substance

hu5B1-TCO and 64Cu-Tz-SarAr

What this could lead to

If successful, this could lead to a more precise way to detect certain cancers using PET scans.

What could go wrong

This trial was withdrawn before enrolling any participants, so no results are available. The approach is still very early and unproven.
