New scan could reveal hidden joint inflammation in arthritis patients
NCT ID NCT03546335
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a radioactive imaging agent called 89Zr-Cimzia in 10 people with rheumatoid arthritis. The goal is to see if it can highlight inflamed joints on a PET scan, comparing painful joints to pain-free ones. The study is currently suspended, and it is exploratory, meaning it aims to gather information rather than treat the disease.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
89Zr-DFO-Certolizumab pegol (a radioactive imaging agent)
What this could lead to
If successful, this could lead to a new way to see inflammation in joints using PET scans, helping doctors better understand and monitor rheumatoid arthritis.
What could go wrong
This is a very early, small study with only 10 participants. It is currently suspended, and the imaging agent is experimental. It may not show clear differences between painful and pain-free joints.
