Introduction
The aim of this study was to describe the real-world evidence for effectiveness, treatment persistence, and treatment patterns among patients in the community with rheumatoid arthritis treated with the JAK inhibitor tofacitinib.
Methods
This was a retrospective, non-interventional cohort study that extracted data for new users of tofacitinib or biologic disease-modifying antirheumatic drugs (bDMARDs) from the Australian Optimizing Patient outcomes in Australian RheumatoLogy (OPAL) dataset between March 2015 and September 2018. Patients were propensity score matched at a 1:2 tofacitinib to bDMARD ratio based on age, sex, and selected baseline treatment combinations. Treatment effectiveness was evaluated using disease status measures. Treatment persistence was calculated and the percentage of patients receiving monotherapy or combination therapy at treatment initiation was evaluated.
Results
Data from 2810 patients were extracted and 1950 patients were included in the matched population (1300 bDMARD initiators and 650 tofacitinib initiators). Patients were predominantly aged 55 to 74 years (57.8%) and female (81.2%). After 18 months of treatment, 52.4% and 57.8% of patients had achieved disease activity score (DAS) remission in the bDMARD and tofacitinib groups, respectively. The median treatment persistence for tofacitinib was similar to that for bDMARDs: 34.2 months (95% CI 32.2 to not reached) and 33.8 months (95% CI 28.8 to 40.4), respectively. In the overall population, more patients were prescribed tofacitinib as monotherapy (43.4%) compared with bDMARD monotherapy (33.4%).
Conclusions
Tofacitinib demonstrated treatment effectiveness and persistence similar to bDMARDs. Overall, there was a trend for more use of tofacitinib as monotherapy than bDMARDs.
Key Points | |
• This study provides real-world evidence regarding effectiveness, treatment persistence, and treatment patterns, among patients with rheumatoid arthritis (RA) in the community being treated with tofacitinib. | |
• The study suggests that tofacitinib is an effective and enduring intervention in RA with tofacitinib persistence and effectiveness comparable to bDMARDs. |
