Background: Psoriasis patients with poor therapeutic response to multiple biologic agents are not well-characterized.
Objective: To describe the characteristics associated with development of multiple biologic failure (MBF) versus good clinical response (GR) to the first biologic.
Methods: This prospective cohort analysis evaluated patients in the multicenter CorEvitas Psoriasis Registry who initiated their first biologic between 2015 and 2020 and were followed for ≥24 months. Multivariable logistic regression identified sociodemographic, clinical, and patient-reported outcomes that differed between MBF (discontinued ≥2 biologics of different classes, each used for ≥90 days, due to inadequate efficacy) and GR (continued use of first biologic for ≥2 years) patients.
Results: One thousand thirty-nine patients were analyzed (490 GR [47.2%], 65 MBF [6.3%]). Female sex, shorter psoriasis duration, earlier year of biologic initiation, prior nonbiologic systemic therapy use, history of hyperlipidemia, and Medicaid insurance were significantly associated with MBF, though the latter 2 variables exhibited wider confidence intervals, indicating a lower level of support. The first-to-second biologic sequence most observed with MBF was Tumor necrosis factor-α inhibitor to IL-17 inhibitor use.
Limitations: Biologic adherence between visits was not evaluated.
Conclusion: Approximately 6% of psoriasis patients met MBF criteria. The results identify characteristics associated with MBF that may distinguish patients warranting more frequent follow-up.
