Summary

This study uses special PET scans to track where an experimental drug called CIT-013 goes in the body of people with rheumatoid arthritis. The drug aims to calm inflammation caused by immune cell traps. About 12 people aged 60-85 will receive a radioactive version of the drug and have full-body scans to see how it spreads. The goal is to learn more about how the drug works, not to test if it cures the disease.
