ANALYSIS OF THE RESULTS OF TOFACITINIB THERAPY IN REAL CLINICAL PRACTICE ACCORDING TO THE ALL-RUSSIAN ARTHRITIS REGISTRY (OREL)

Objective: to analyze the results of tofacitinib (TOFA) therapy in real clinical practice according to the All-Russian Arthritis Registry (OREL). Subjects and methods. The OREL Registry included 347 patients (286 (82%) women and 61 (18%) men) with rheumatoid arthritis (RA) who initiated TOFA therapy. The male:female ratio was 1:4.7. The patients’ median age at onset of the disease was 42 years; its duration was 8 years. Most of the patients included in the registry had extended- (n=171 (52%)) or late- (n=148 (45%)) stage of RA. Results and discussion. Prior to initiation of TOFA therapy, RA activity according to DAS28 was high and moderate in 91 (64.5%) and 40 (28.4%) patients, respectively; the median DAS28 value was 5.5 [4.6; 6.2]; SDAI – 30.5 [21.4; 42.9], and CDAI – 28.2 [20.0; 37.1]. The use of TOFA was accompanied by significant decrease of disease activity. After 12 weeks, high RA activity was persistent in 32 (22.7%) patients; the number of patients with moderate activity increased to 77 (54.6%), that of those with low activity rose to 15 (10.6%); remission was observed in 17 (12.1%) patients. 216 (62.6%) and 76 (22%) patients received TOFA as first- and second-line therapy, respectively. TOFA was most frequently prescribed when tumor necrosis factor-á inhibitors (19.6%), rituximab (7.8%), tocilizumab (4.3%), and abatacept (5.2%) were insufficiently effective or poorly tolerated. Conclusion. The results of using TOFA in real clinical practice may suggest that the drug has high efficacy in patients with RA. TOFA can be used at a dose of 5 or 10 mg twice daily as both alone and in combination with disease-modifying anti-rheumatic drugs. TOFA showed similar efficacy in patients who had earlier taken biological agents and in those who had not
