Biologic therapies (including biologic medications like Enbrel, Humira, Remicade, Cimzia, Simponi, Actemra, Rituxan and Orencia) have changed the treatment of RA, but the differences in safety and/or effectiveness of each biologic therapy are not all known. We are doing this study in order to try to see if one or more of these treatments are better than the others. The use of databases like the CORRONA Organization database gives us information that helps us to understand why such drugs are used, reasons for starting or stopping drugs, for whom they are prescribed, and to monitor changes in patients' abilities to perform daily activities and gather information on family or social history.
