This is a longitudinal, observational, prospective cohort study to assess the safety and efficacy of RemsimaTM in patients with RA in comparison with patients receiving non-biologic treatmentsor other anti-TNF drugs. For the RemsimaTM cohort data will be collected for patients who commence treatment with RemsimaTM in accordance with the product label at the time of enrolment (3 mg/kg of RemsimaTM by IV infusion at weeks 0, 2, 6 (±3 days) and every 8 weeks (±14 days) thereafter). For patients who have been treated with Remicade® prior to enrolment, their dosing schedule will be continued appropriately. This observational study allows drug switching between anti-TNF drugs. If switched to RemsimaTM, data will be collected until the end of study for each patient. If switched to other anti-TNF drugs (infliximab (Remicade®), etanercept, adalimumab and etc.), data will be collected until 1 year from the day of switch or until the end of study for each patient, whichever reaches earlier.
