The second group will consist of RA patients that did not respond to "DMARDs". These patients will further receive (DMARDs) such as methotrexate, plaquenil and/or prednisone as well as Cimzia® (provided to us by UCB) free of charge. Cimzia® is a FDA approved drug and is a standard of care. Blood samples will be obtained from the patients treated with DMARDs including methotrexate, plaquenil, and/or prednisone and Cimzia® (provided to us by UCB) that have inactive remission (DAS28<2.6). In this group, blood samples will be collected onset of the study as well as 3 and 6 months after treatment with Cimzia at patient's visit through our collaboration with the aforementioned rheumatologists. Patients receiving intra-articular steroid injections will be excluded from the study.
