Background Drug survival rates in patients with psoriasis had been described extensively. Different survival rates of TNF-alpha inhibitors (TNFIs), ustekinumab and secukinumab were reported. Objectives To investigate drug survival rates of TNFIs, ustekinumab and secukinumab, with particular emphasis on the difference between ustekinumab and secukinumab. Methods Survival analysis was performed in patients with moderate-to-severe psoriasis who received adalimumab, infliximab, etanercept, ustekinumab and secukinumab treatment in 2002-2018, using the Clalit Health Services database. Stratified analysis was performed according to biologic treatment lines. Multivariate analysis was performed adjusting for demographic variables, calendar year, metabolic syndrome, psoriatic arthritis, biologic treatment line, biologic naivety, co-administration of oral treatments and previous oral systemic treatment exposure. Results Among 1459 patients treated with 3070 biologic medication courses, ustekinumab had a significantly higher crude survival as compared with TNFIs and secukinumab. The mean drug survival of ustekinumab, adalimumab, etanercept, infliximab and secukinumab was 43.5 (CI: 39.7-47.2), 38.2 (CI: 34.8-41), 33.9 (CI: 30.8-37.1), 28.2 (CI: 22.5-33.8) and 17.1 (CI: 15.6-18.6) months, respectively, with significant statistical differences for all comparisons (P < 0.001). The differences between ustekinumab and secukinumab were not significant following adjustment to factors that included treatment line (hazard rate 1.16, CI: 0.93-1.43). Conclusion Different drug survival rates between ustekinumab and secukinumab are determined by the treatment line and calendar year, reflecting the availability of biologic medications, and not only by the biologic attributes of each medication.
