New PET scan tracer could reveal hidden cancer markers

NCT ID NCT06383598

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new radioactive tracer called [68Ga]Ga-THP-PDL1-3 for PET/CT scans in 50 adults with solid tumors. The goal is to see if it can safely and accurately show PD-L1 levels in tumors, which may help doctors personalize cancer treatment. Participants will receive both the new tracer and a standard FDG scan. The study focuses on safety, image quality, and radiation dose.

What this could mean

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

Active substance

[68Ga]Ga-THP-PDL1-3 (a radioactive tracer for PET scans)

What this could lead to

If successful, this could provide a non-invasive way to see PD-L1 levels in tumors, helping doctors choose the right treatments and monitor response without repeated biopsies.

What could go wrong

This is a very early, small pilot study (50 people) focused on safety and feasibility, not on treatment outcomes. The tracer may not reliably reflect PD-L1 changes, and results may not apply to all cancer types.
