New blood protein may reveal hidden arthritis activity
NCT ID NCT07374367
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a protein called isthmin-1 in the blood of people with rheumatoid arthritis (RA) compared to healthy volunteers. Researchers want to see if higher levels of this protein match up with more active disease, as seen on ultrasound scans. The goal is to find a simple blood test that helps doctors better track RA. About 66 adults with RA will take part.
