Researchers are evaluating the persistence of two treatments, upadacitinib UPA and tumor necrosis factor inhibitors TNFi, in adults with moderate to severe active rheumatoid arthritis RA. This observational study is conducted in Germany with about 678 participants across roughly 80 sites. The purpose is to compare how long participants continue their prescribed treatment under real-world conditions over time. Participants will receive either UPA or TNFi treatment as prescribed by their doctors, following local labels and standard care practices. Treatment decisions were made before joining the study and are independent of recruitment. The study will observe participants for up to 24 months to assess retention rates on these treatments. During the study, participants will be monitored regularly according to local care standards. Researchers will collect data on how long participants stay on their assigned treatment, focusing on retention rates over approximately 24 months. Study participation may last up to two years, with recruitment expected to take about 24 months, resulting in a total study duration of about 48 months.

Researchers are conducting a prospective, non-interventional observational study to understand how patients aged 6 years and older with atopic dermatitis AD respond to treatment with dupilumab in everyday medical practice. The study aims to characterize these patients by examining their medical history, demographic and disease-related features, associated allergic conditions, other type 2 inflammation diseases, and their past and current treatments. The study will also assess the long-term effectiveness and safety of dupilumab over two years, focusing on disease control and quality of life.
