New PET scan tracer could sharpen view of melanoma treatment response

NCT ID NCT07215182

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial is testing whether a new radioactive tracer, [68Ga]Ga-FAPI-46, can improve how doctors evaluate response to immunotherapy in patients with stage IV melanoma. Twenty participants will receive two experimental PET/CT scans—one before starting immunotherapy and one after three months—along with blood samples. The results will be compared with standard FDG PET/CT scans to see if the new tracer provides clearer information about tumor changes.

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-FAPI-46 (an experimental imaging tracer)
What this could lead to
If successful, this could provide a more accurate way to measure how well immunotherapy is working in advanced melanoma patients, potentially guiding treatment decisions.
What could go wrong
This is a small, early-phase study (20 participants) focused on imaging, not treatment. The tracer may not prove more useful than current standard scans, and results may not apply to all patients.
