68Ga-FAPI46 PET/CT for chronic inflammatory and fibrotic diseases

68Gallium-FAPI46 PET/CT Imaging in Chronic Inflammatory and Fibrotic Diseases

Not applicable Interventional University Hospital, Brest · NCT06275477

We will try a new PET/CT scan using 68Ga-FAPI46 to see if it helps detect and monitor chronic inflammatory and fibrotic conditions in adults.

What this trial studies

This single-center pilot uses 68Ga-FAPI46 PET/CT, a radiotracer that binds fibroblast activation protein, to image a range of chronic inflammatory and fibrosing conditions. Thirteen clinical situations—including rheumatoid arthritis, liver fibrosis, and systemic lupus—are included to explore where the tracer may add diagnostic or monitoring value. Participants who meet consensus diagnostic criteria will receive the PET/CT and imaging findings will be compared with existing clinical and imaging information to characterize tracer uptake patterns. The project aims to identify promising applications for further development and to refine how this imaging could be integrated into routine care.

Who should consider this trial

Good fit: Adults (18+) with one of the specified chronic inflammatory or fibrotic conditions who meet consensus diagnostic and clinical criteria, can give informed consent, are not pregnant or breastfeeding, and have local social security coverage are ideal candidates.

Not a fit: Patients with active cancer, pregnant or breastfeeding women, those unable to consent, or people whose condition is not among the 13 selected clinical situations are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the scan could improve detection and monitoring of activated fibroblast activity, enabling earlier or more targeted treatment decisions for patients with inflammatory or fibrotic diseases.

How similar studies have performed: 68Ga-FAPI tracers have shown promising diagnostic performance compared with 18F-FDG in oncology, but evidence in non-oncologic inflammatory and fibrotic diseases is limited and remains exploratory.
