Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
