Abstract
Objectives: To analyse and compare drug-survival of adalimumab and etanercept (and their biosimilars) in biologic-naïve patients with ERA (Enthesitis-Related Arthritis). // Methods: In this retrospective observational study, conventional statistics and machine-learning were applied to compare drug-survival (adalimumab, etanercept and their biosimilars initiated: 2009–2019) in ERA and identify determinants. The primary outcome was discontinuation of treatment due to primary- or secondary-failure and adverse drug-reactions. // Results: During the observation period, 99 of 188 patients with ERA on first-line TNF inhibitors (etanercept-n=108, adalimumab-n=80) discontinued their treatment (median survival-time 3.9years, 95%CI 2.6-4.9years). Adalimumab was associated with longer drug-survival compared to etanercept especially after an initial positive response, with the median time to treatment discontinuation 4.9years (95% CI 3.9–5.7) for adalimumab, compared to 2years (95%CI 1.4–4.0) for etanercept (HR of treatment-discontinuation-0.49, 95%CI 0.32–-0.75, p=0.001). Adjusted by propensity-score, adalimumab-methotrexate combination was associated with longer drug survival, compared to adalimumab-monotherapy (HR-0.41, 95%CI 0.20–0.85), etanercept-monotherapy (HR-0.28, 95%CI 0.15–0.53), and etanercept-methotrexate combination (HR-0.39, 95%CI 0.21–0.73). The presence of HLA-B27 was associated with longer drug-survival (HR-0.50, 95%CI 0.29–0.87) following an initial positive response. Higher-CRP at baseline was associated with higher rate of primary-failure (HR-1.68, 95%CI 1.08–2.62). Axial-ERA (sacroiliitis±spinal-involvement) was associated with poorer drug-survival for both primary- and secondary-failure (overall HR-2.03, 95%CI 1.22–3.40). Adjusted by propensity-score, shorter drug-survival was observed in patients with baseline-CRP≥12.15 mg/L, but only in the context of axial-ERA, not in peripheral-ERA (no sacroiliitis/spinal-involvement) (HR-2.28, 95%CI 1.13–-3.64). // Conclusion: Following an initial positive primary response, continuing methotrexate with adalimumab was associated with the longest drug-survival compared to adalimumab-monotherapy or etanercept-based regimens. Axial-ERA was associated with a poorer drug-survival. A CRP >12.15 in patients with axial-ERA was associated with a higher rate of primary-failure. Further prospective studies are required to confirm these findings.
