摘要

Objectives

To compare effectiveness of tofacitinib versus tumor necrosis factor inhibitors (TNFi), and across tofacitinib lines of therapy, in patients with rheumatoid arthritis (RA), using US CorEvitas RA Registry data.

Methods

Analysis included patients with RA initiating tofacitinib or TNFi with a 12-month follow-up visit between November 2012–February 2021. Primary (Clinical Disease Activity Index-defined low disease activity [CDAI-LDA: CDAI ≤ 10]) and secondary (clinical/disease activity/patient-reported) effectiveness outcomes were assessed at month 12. Outcomes were stratified by treatment regimen (overall tofacitinib vs overall TNFi/tofacitinib monotherapy vs tofacitinib combination therapy/TNFi monotherapy vs TNFi combination therapy/tofacitinib monotherapy vs TNFi combination therapy/tofacitinib combination therapy vs TNFi combination therapy), or tofacitinib line of therapy (2nd/3rd/ ≥ 4th line).

Results

3,481 eligible patients initiated tofacitinib (n = 805) or TNFi (n = 2,676). Improvements in effectiveness at month 12 were generally similar across treatment regimens; 25.1% and 30.1% of overall tofacitinib and TNFi initiators achieved CDAI-LDA, respectively (odds ratio 1.29 [95% confidence interval (CI) 0.94, 1.76]). Odds ratios (95% CIs) for achieving CDAI-LDA at 12 months were 0.70 (0.36, 1.37) for 3rd- versus 2nd-line, and 1.09 (0.63, 1.88) for 3rd- versus ≥ 4th-line tofacitinib initiators. At month 12, mean change from baseline in CDAI was greater among 3rd- versus ≥ 4th-line tofacitinib initiators, and mean Health Assessment Questionnaire and patient-reported pain were greater in 3rd- versus 2nd-line and ≥ 4th- versus 3rd-line tofacitinib initiators.

Conclusions

Generally, there were no differences in effectiveness between tofacitinib versus TNFi regimens. Few differences were observed between tofacitinib lines of therapy; sample sizes were small for 2nd/3rd-line initiators.

Study registration

NCT01402661 (ClinicalTrials.gov; July 25, 2011).

Key Points

• Using data from the US CorEvitas rheumatoid arthritis (RA) Registry, this study compared the effectiveness of tofacitinib versus tumor necrosis factor inhibitors (TNFi) and across tofacitinib lines of therapy.

• Effectiveness of tofacitinib was similar to TNFi regimens up to month 12, while differences in some effectiveness outcomes at month 12 were observed with tofacitinib across different lines of therapy.

• The findings of this study may inform future treatment decision-making in patients with RA.
