Real-World Treatment and Care Patterns in Patients With Rheumatoid Arthritis Initiating First-Line Tumor Necrosis Factor Inhibitor Therapy in the United States

OBJECTIVE

Treatment guidelines for rheumatoid arthritis (RA) recommend targeting low disease activity or remission and switching therapies for patients not reaching those targets. We evaluated real-world use of disease activity measures, treatment discontinuation, and switching patterns among patients with RA initiating a first-line tumor necrosis factor inhibitor (TNFi).

METHODS

Data from adult patients with RA initiating a first-line TNFi were collected from the American Rheumatology Network (January 2014-August 2021). The proportion of patients with recorded disease activity scores (Clinical Disease Activity Index [CDAI] or Routine Assessment of Patient Index Data 3 [RAPID3]) at TNFi initiation was assessed. Among patients with moderate or severe RA at TNFi initiation, reasons for discontinuation and subsequent advanced therapy were evaluated.

RESULTS

Among TNFi initiators (n = 15,182), 44.8% recorded a CDAI/RAPID3 score at treatment initiation; of those who did not, 47.0% had recorded a tender and/or swollen joint count or pain score. Among patients with moderate or severe RA (n = 1,651), 52% discontinued their initial TNFi during follow-up, of which 15%, 46%, 28%, and 12% initiated the same TNFi, another TNFi, a non-TNFi biologic, or a Janus kinase inhibitor, respectively. The proportion of patients restarting the same TNFi or initiating another TNFi varied according to TNFi discontinuation reason.

CONCLUSION

In clinical practice, over half of patients with RA initiating a first-line TNFi did not have baseline disease activity assessments. Many patients cycled through TNFi despite citing lack of efficacy as the most common reason for discontinuation. Consistent, objective monitoring of treatment response and timely switch to effective therapy is needed in patients with RA.

Real-World Use and Effectiveness Outcomes in Patients with Rheumatoid Arthritis Treated with Upadacitinib: An Analysis from the CorEvitas Registry

INTRODUCTION

Data assessing longer-term real-world effectiveness and treatment patterns with upadacitinib (UPA), a Janus kinase inhibitor, in rheumatoid arthritis (RA) are lacking. We assessed improvement in clinical and patient-reported outcomes and treatment patterns for up to 12 months among adult patients with RA initiating UPA.

METHODS

Data were collected from the CorEvitas® RA Registry (08/2019-04/2022). Eligible patients had moderate to severe RA (Clinical Disease Activity Index [CDAI] > 10) and follow-up visits at 6 or 12 months after UPA initiation. Outcomes were mean change from baseline, percentage achieving minimal clinically important differences (MCID) in clinical and patient-reported outcomes, and disease activity at follow-up. We evaluated clinical outcomes and therapy changes among patients with tumor necrosis factor inhibitor (TNFi) experience and among those receiving UPA as first-line therapy, as well as those receiving UPA as monotherapy versus as part of combination therapy. We further evaluated whether outcomes were similar among those that remained on therapy.

RESULTS

Patients treated with UPA (6-month cohort, N = 469; 12-month cohort, N = 263) had statistically significant improvements (p < 0.001) in mean CDAI, tender/swollen joint counts, pain, and fatigue at follow-up. At 12 months, 46.0% achieved MCID in CDAI and 40.0% achieved low disease activity/remission. Overall, 43.0% discontinued UPA at 12 months; of those receiving combination treatment (N = 90) with conventional therapies and UPA, 42.2% (N = 38) discontinued conventional therapy. Findings were similar in the 6-month cohort and among subgroups. Changes from baseline and proportions of patients achieving MCID or clinical outcomes tended to be numerically lower among patients with TNFi experience and numerically higher among those receiving UPA as first-line therapy.

CONCLUSIONS

UPA initiation was associated with improvements in clinical and patient-reported outcomes, with meaningful clinical improvements regardless of prior TNFi experience, line of therapy, or concomitant use of conventional therapies. Further research is needed to better understand sustained response of UPA over longer treatment periods.
