Summary

This study explores whether a special type of PET scan, called PSMA PET, can help doctors see how well the salivary glands are working in people with Sjögren's syndrome. Researchers will compare these scans with another type of PET scan (FAPI PET) that shows inflammation. The goal is to find a better way to diagnose and monitor this autoimmune disease. The trial will include 60 adults: some with Sjögren's, some with normal glands, and some with prostate cancer.

What this could mean

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

Active substance: PSMA PET/CT and FAPI PET/CT imaging scans
What this could lead to: If successful, this could lead to a new, non-invasive way to diagnose and monitor Sjögren's syndrome using PET scans, helping doctors better stage the disease and guide treatment.
What could go wrong: This is a small, early-stage imaging study, not a treatment trial. The scans may not prove useful for routine diagnosis, and results may not apply to all patients with Sjögren's.
