Guselkumab is an IL‐23 inhibitor that has been demonstrated to be effective and safe for the treatment of moderate‐to‐severe plaque psoriasis in clinical trials. The data pool relating to the use of guselkumab in a real‐life setting is still lacking. To evaluate the efficacy and safety of guselkumab in a real‐life setting, focusing on predictors of early clinical response, a single‐center prospective study was conducted enrolling patients with moderate‐to‐severe psoriasis. The clinical data relating to the efficacy and safety of the drug were acquired at initiation of treatment and at all subsequent clinical follow‐ups: the primary endpoint was PASI90 and PASI100 response at week 12, 24, and 48. Out of the total cohort of 74 patients, 62 (83.8) reached a 48‐week follow‐up 64 (87.8%) reached a 24‐week follow‐up, while 72 (97.3%) a 12‐week follow‐up. Treatment with guselkumab reduced the mean PASI from the initial 11 ± 6.3 to 2.5 ± 3.1 at 12 weeks, to 1.2 ± 1.8 at 24 weeks, and to 0.8 ± 1.6 at 48 weeks. At week 12, a PASI 90 and PASI 100 response was achieved by 44.4% and 23.6% of patients, respectively. After 24 weeks, 63% of patients reported a PASI 90 while 46.1% achieved PASI 100. Previous treatment with one or more other biologics did not impact significantly on the achievement of the PASI 90 and 100 at any endpoints analyzed. We reported no difference between bio‐naïve and non‐naïve patients in the response to guselkumab, high safety, and efficacy was showed in both populations. [ABSTRACT FROM AUTHOR]
