Summary

This study tests a new daily pill called ivarmacitinib for people with rheumatoid arthritis (RA) who did not get better with standard first treatments. The goal is to see if it can reduce joint pain and swelling and control the disease. About 100 adults with moderate to severe RA will take the drug for 12 weeks, and doctors will check how many achieve at least 20% improvement in symptoms.
