New PET tracer could spot hidden heart scarring in rare amyloidosis

NCT ID NCT07549841

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

Summary

This study tests a special radioactive tracer called [68Ga]Ga-FAPI-46 for PET scans in 40 people with transthyretin cardiac amyloidosis (ATTR-CM), a condition where abnormal proteins build up in the heart. The goal is to see if this scan can measure scar-like activity in the heart muscle and help doctors tell how advanced the disease is or if it's getting worse. If it works, it could lead to better staging and personalized treatment decisions.

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 (a radioactive tracer for PET imaging)

What this could lead to

If successful, this imaging method could help doctors better stage the disease and identify which patients are worsening, leading to more personalized treatment.

What could go wrong

This is a small, early-phase study with only 40 participants, so results may not apply to everyone. The tracer's ability to predict progression needs further validation.
