THU0171 TOFACITINIB, AN ORAL JANUS KINASE INHIBITOR, IN THE TREATMENT OF RHEUMATOID ARTHRITIS – THE RESULTS OF RUSSIAN NATIONAL REGISTER OF PATIENTS WITH RHEUMATOID ARTHRITIS TREATED WITH TOFACITINIB

Background: Tofacitinib (TF) is an oral Janus Kinase inhibitor for the treatment of rheumatoid arthritis (RA). Objectives: To evaluate the one-year effectiveness of tofacitinib as first-line therapy in RA conventional synthetic (cs) DMARDs non-responders. Methods: Data from 415 patients from Russian national register of patients with RA treated with TF were analyzed. 119 RA patients, who had complete clinical and laboratory data from 4 consecutive visits after baseline with an interval of 3 months between the visits and who used the TF as first-line therapy after failure of cs DMARDs, were included. Treatment with any biologics ever was an exclusion criteria. Demographical (age, sex) and RA activity data (DAS28, SDAI, number of tender and swollen joints (NTJ, NSJ), erythrocytes sedimentation rate (ESR), C-reactive protein (CRP), and HAQ, EQ5D were collected, table 1. Statistical analysis performed in SPSS2017. p-value Results: At baseline 12 (10%) were treated with NSAIDs, 15 (12.6) with 5-10 mg/dayof prednisolone, 82 (68.9) – with methotrexate (10-25 mg/week), 8 (6.7%) – with sulfasalazine (2.0-3.0 g/day). Changes in the disease activity in patients with RA, treated with tofacitinib after csDMARD are presented in Table 2 At visit 3 DAS28 Conclusion: Treatment with TF may provide good response rates in RA patients, refractory previous cs DMARDs.
