Researchers are evaluating the retention rates of two treatments, upadacitinib UPA and tumor necrosis factor inhibitors TNFi, in adults with moderate to severe active rheumatoid arthritis RA in a real-world setting in Germany. This observational study aims to compare how long patients stay on each treatment when prescribed according to local standards and labels. About 678 participants will be enrolled over approximately 24 months, with total study duration lasting up to 48 months. Participants will receive either upadacitinib or a TNFi treatment as prescribed by their physicians following local regulatory and reimbursement guidelines. The decision to treat with UPA or TNFi is made independently of the study and before recruitment. The study does not assign treatments but observes patients already prescribed these therapies. During the study, researchers will monitor participants for up to 24 months to measure retention rates of the treatments. Data collection will include regular assessments according to routine care practices to track treatment persistence. The study focuses on real-world outcomes without altering standard treatment or care. Safety monitoring and follow-up will be conducted as part of usual medical care.
