A Retrospective, Observational Chart Review of Biologics in Monotherapy Versus the Combination Biologic Plus Methotrexate in Patients With Rheumatoid Arthritis

This cross-sectional, non-interventional, retrospective chart review will compare the efficacy and safety of biologic monotherapy and biologic and methotrexate combination therapy in patients with rheumatoid arthritis who have had an inadequate response to prior treatment with disease-modifying anti-rheumatic drugs including methotrexate. Data will be collected from patients who have been on first-line biologic treatment for at least 6 months.
