Effectiveness and Safety of Tofacitinib in Korean Patients With Rheumatoid Arthritis

Study Overview
=================
Brief Summary
-----------------
The objectives of this single center, prospective, non-interventional inception cohort is to understand patient characteristics, general treatment patterns, effectiveness, and safety of Tofacitinib for rheumatoid arthritis patients in the real-world setting. To evaluate the baseline characteristics of Korean RA patients treated with Tofacitinib To evaluate the effectiveness and safety of Tofacitinib in clinical practice in Korean RA patients. To further evaluate safety, effectiveness and demographic characteristics of the patients treated with Tofacitinib matched with and compared to biologic DMARDs from the BIOPSY registry database.
