Tildrakizumab for the Treatment of Moderate-to-Severe Psoriasis: Results from 52 Weeks Real-Life Retrospective Study

Background: Tildrakizumab, an anti-IL-23, showed promising efficacy and safety profiles in two randomized clinical-trials (reSURFACE-1 and reSURFACE-2), comparing tildrakizumab superiority to placebo and etanercept. Due to its recent availability in clinical-practice, real-life data are still limited. Objective: To assess the efficacy and safety of tildrakizumab in a real-world-practice in patients suffering from moderate-to-severe psoriasis. Methods: A 52-week observational retrospective study enrolled patients suffering from moderate-to-severe plaque-psoriasis, starting tildrakizumab treatment. Results: A total of 42 patients were included in the study. Mean PASI showed a significant reduction at each follow-up (p<0.001), reducing from 13.5±5.9 at baseline, 2.8±3.8 at week-28, resulting stable up to week-52. High rates of patients reached both PASI90 and PASI100 responses at both week 16 (PASI90: 52.4%, PASI100: 33.3%) and week 28 (PASI90: 76.1%, PASI100: 61.9%), maintaining these up to week 52 (PASI90: 73.8%, PASI100: 59.5%). The impact of treatment on patient's quality of life has been evaluated with DLQI, which showed a significant reduction during follow-ups. Conclusion: Our data confirm tildrakizumab as an effective and generally safe treatment for the management of moderate-to-severe psoriasis, with high rates of both PASI90 and PASI100 responses, and very few reported adverse events, up to 52 weeks of follow-up.
