Real-world effectiveness and safety of guselkumab in adult patients with facial and/or genital psoriasis: a 52-week analysis from the Italian multicentric GULLIVER study

Facial and genital plaques are common manifestations of psoriasis, are challenging to treat, and significantly impact patients’ quality of life (QoL). GULLIVER is a prospective, non-interventional study conducted in 2020–2023 in Italy, aimed at examining the effectiveness, safety and QoL impact of guselkumab through 52 weeks of treatment in patients with facial and/or genital psoriasis. The primary endpoint was the percentage of patients achieving a static Physician Global Assessment (sPGA) score of ≤1 and a minimum 2-grade improvement in sPGA score at Week 52. Of 351 enrolled patients, 88.6% remained on guselkumab treatment at Week 52. The proportions of patients achieving the sPGA targets in the facial and genital groups, respectively, were 83.3% and 76.5% at week 12, increasing to 93.8% and 97.9% at Week 52. Mean Dermatology Life Quality Index score improved from 12.0 ± 7.5 at baseline to 1.1 ± 2.0 at Week 52 for patients with facial psoriasis (p-value
