Popis: Introduction No published studies exist comparing the effectiveness of tofacitinib with other advanced therapies for the treatment of rheumatoid arthritis (RA) in real-world clinical practice. Here, we report differences in effectiveness of tofacitinib compared with standard of care, tumor necrosis factor inhibitors (TNFi), with or without concomitant methotrexate (MTX), using US Corrona registry data. Methods This observational cohort study included RA patients receiving tofacitinib (from 6 November 2012; N = 558) or TNFi (from 1 November 2001; N = 8014) with or without MTX until 31 July 2016. Efficacy outcomes at 6 months included modified American College of Rheumatology 20% responses, Clinical Disease Activity Index (CDAI) and Pain. Outcomes were compared between patients receiving TNFi and tofacitinib with or without MTX and by line of therapy. Outcomes within therapy lines were compared using propensity-score matching; between-group differences were estimated using mixed-effects regression models. Results Patients receiving tofacitinib had longer RA duration and a greater proportion had previously received biologics than those receiving TNFi; other baseline characteristics were comparable. In patients receiving second- and third-line TNFi therapy, CDAI low disease activity/remission response rates were significantly better with concomitant MTX. Too few patients received tofacitinib as second line for meaningful assessment. No significant differences were observed in outcomes between tofacitinib as monotherapy and tofacitinib with concomitant MTX. Conclusions In clinical practice, TNFi efficacy is improved with concomitant MTX in the second and third line. In the third/fourth line, patients are likely to achieve similar efficacy with tofacitinib monotherapy, or TNFi or tofacitinib in combination with MTX.
