Abstract

Background: Guselkumab, a fully human interleukin-23 antibody, is approved for systemic treatment of patients with moderate-to-severe plaque psoriasis. Objectives: To compare the efficacy and safety of guselkumab with those of fumaric acid esters (FAE) in patients with moderate-to-severe plaque psoriasis who are naive to systemic treatment. Methods: Eligible patients were randomized to this multicentre, randomized, open-label, assessor-blinded, active-comparator-controlled phase IIIb study to receive guselkumab 100 mg by subcutaneous injection or oral FAE according to local label guidelines. Results: Through week 24, 56 of 60 patients completed guselkumab treatment and 36 of 59 completed FAE treatment. The primary endpoint (proportion of patients with ≥ 90% improvement from their baseline Psoriasis Area and Severity Index; PASI 90 response) was achieved by significantly more patients receiving guselkumab than FAE at week 24 (82% vs. 14%, P < 0·001). Analysis of the major secondary endpoints confirmed a statistically significant difference between the treatments with regards to PASI 75 response (90% vs. 27%, P < 0·001) and Dermatology Life Quality Index score of 0 or 1 (no effect at all on the patient's quality of life; 62% vs. 17%, P < 0·001). More patients in the guselkumab group achieved completely clear skin (PASI 100 response) than in the FAE group (32% vs. 3%, P < 0·001). The incidence of adverse events was lower with guselkumab than with FAE (73% vs. 98%). Overall, 28% of patients on FAE discontinued due to an adverse event, compared with none receiving guselkumab. No new safety findings were observed for guselkumab. Conclusions: Guselkumab demonstrated superiority over FAE in systemic-treatment-naive patients with moderate-to-severe plaque psoriasis through 24 weeks.
