New hope for tough arthritis cases: experimental drug enters Mid-Stage trial
NCT ID NCT07137598
First seen Jun 27, 2026 · Last updated Aug 26, 2026 · Updated 6 times
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.
