Kidney fibrosis imaging with Ga-68 FAPI PET/CT in CKD

Official title: Evaluation of Renal Renal Fibrosis Vie FAPI-PET-CT: a Prospective Non-randomized Open-label Single-center Pilot Study

Run by Medical University of Vienna · NCT07712679 · Data updated 2026-11-12

This study tests whether a Ga-68 FAPI PET/CT scan can reflect how much fibrosis is in the kidneys of people with chronic kidney disease.

Is this trial a fit for you?

Likely a good fit

Adults with chronic kidney disease who have a prior histological workup of a native kidney and can undergo PET/CT imaging.

Probably not a fit

Patients without sufficient kidney fibrosis signal on imaging or without compatible histology may not benefit from this approach.

What this trial studies

Researchers are evaluating the use of 68Ga-DOTA.SA.FAPi PET/CT to measure kidney fibrosis in CKD patients. The imaging approach aims to provide a noninvasive proxy for fibrosis that traditionally requires biopsy. The study will correlate tracer uptake with histological fibrosis from native kidney tissue and assess feasibility in patients with existing histology. It is conducted at the General Hospital Vienna with patients who have a histological workup of the native kidney. No results are yet reported from this interventional imaging study.

Why it matters

Potential benefit: If successful, this imaging method could reduce the need for invasive kidney biopsies and improve monitoring of fibrosis progression in CKD patients.

How similar studies have gone: Earlier small studies in CKD and other fibrotic conditions suggest PET tracers like FAPI can reflect fibrosis, but CKD evidence remains preliminary.
