Recent knowledge on the key role of interleukin (IL) 23/17 axis in psoriasis pathogenesis, led to development of new biologic drugs. Risankizumab is a humanized immunoglobulin G1 monoclonal antibody specifically targeting IL23. Its efficacy and safety were showed by both clinical trials and real-life experiences. However, real-life data on effectiveness and safety of risankizumab in patients who previously failed anti-IL17 are scant. To assess the efficacy and safety of risankizumab in patients who previously failed anti-IL17. A 52-week real-life retrospective study was performed to assess the long-term efficacy and safety of risankizumab in patients who previously failed anti-IL17. A total of 39 patients (26 male, 66.7%; mean age 50.5 ± 13.7 years) were enrolled. A statistically significant reduction of psoriasis area severity index (PASI) and body surface area (BSA) was assessed at each follow-up (PASI at baseline vs. week 52: 13.7 ± 5.8 vs. 0.9 ± 0.8, p < 0.0001; BSA 21.9 ± 14.6 vs. 1.9 ± 1.7, p < 0.0001). Nail psoriasis severity index improved as well, being statistically significative only at week 16 and thereafter [9.3 ± 4.7 at baseline, 4.1 ± 2.4 (p < 0.01) at week 16, 1.4 ± 0.8 (p < 0.0001) at week 52]. Treatment was discontinued for primary and secondary inefficacy in 1(2.6%) and 3(7.7%) patients, respectively. No cases of serious adverse events were assessed. Our real-life study confirmed the efficacy and safety of risankizumab, suggesting it as a valuable therapeutic weapon among the armamentarium of biologics, also in psoriasis patients who previously failed anti-IL17 treatments.
