NCT ID NCT07118176

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
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 Results may not be published yet.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

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 1 trial is testing a new imaging tracer called 68Ga-FAPI-46 to see where it collects in normal and cancerous tissues. About 30 people with various solid tumors or blood cancers will receive the tracer and then undergo a PET/CT scan. The goal is to understand how the tracer behaves in the body and whether it can help detect cancers that standard FDG-PET scans might miss.

What this could mean

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

Active substance
Gallium Ga 68 FAPi-46
What this could lead to
If successful, this tracer could improve cancer detection and help doctors see tumors that standard scans might miss.
What could go wrong
This is an early phase 1 study with only 30 participants, so results may not apply broadly. The tracer may not highlight all cancer types effectively.
