Abstract
BACKGROUND: Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis. OBJECTIVE: To investigate drug survival in patients with psoriasis treated with biologics. PATIENTS AND METHODS: We performed a comparative evaluation of the achievement of PASI 90 and PASI ≤ 3 at 16, 28, and 52 weeks along with a DS (drug survival) analysis with IL-17 and IL-23 inhibitors brodalumab, ixekizumab, secukinumab, risankizumab, tildrakizumab, and guselkumab on 1,057 patients. RESULTS: IL-17 inhibitors showed a faster achievement of PASI 90 and PASI ≤ 3 with significant superiority over IL-23 inhibitors at week 16 (p < 0.001; 56% vs. 42% and 70% vs. 59%, respectively). A difference was shown in favor of IL-23 inhibitors regarding DS (p < 0.001), which was 88% at 24 months vs. 75% for IL-17 inhibitors. In multivariate analysis, IL-23 inhibitors (HR 0.54 CI 0.37-0.78, p = 0.001), and male sex (HR 0.57 CI 0.42-0.76, p < 0.001) were all associated with a lower probability of drug interruption. Risankizumab (HR 0.42 CI 0.26-0.69, p = 0.001), guselkumab (HR 0.49 CI 0.24-0.99, p = 0.046), and male sex (HR 0.57 CI 0.43-0.77, p < 0.001) were associated with a lower probability of drug interruption than secukinumab. CONCLUSIONS: IL-23 inhibitors showed the best performance on DS. Overall, the most effective class was IL-17 inhibitors considering the short-term effectiveness, but long-term effectiveness is in favor of anti-IL-23.
