Summary

This study tests an experimental drug called Afimkibart (RO7790121) in 160 people with moderate to severe rheumatoid arthritis who did not get better with or could not tolerate standard treatments like TNF or JAK inhibitors. Participants will receive either the drug or a placebo to see if it reduces joint swelling and pain. The goal is to find a new option for controlling this chronic autoimmune disease.
