Abstract

Background: Interleukin-17 antagonists have received a first-line label for moderate-to-severe plaque psoriasis. Objectives: We conducted the first head-to-head trial between the two most commonly used first-line therapies in Germany, fumaric acid esters (FAEs) and methotrexate, and the interleukin-17A antagonist, ixekizumab. Methods: Systemic-naive patients were randomized in this parallel-group, active-comparator, open-label, rater-blinded trial (each group n = 54). The primary outcome was the proportion of patients achieving ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) at 24 weeks. Key secondary outcomes included 24-week PASI 90 and 100, static Physician's Global Assessment (sPGA) score of 0 or 1, and Dermatology Life Quality Index (DLQI) score of 0 or 1. Safety events at week 24 were analysed using Fisher's exact test. Missing data were imputed using nonresponder imputation. The trial was registered at ClinicalTrials.gov (NCT02634801) and EudraCT (2015-002649-69). Results: At week 24, more ixekizumab-treated patients achieved PASI 75 [91% vs. 22% FAEs (P < 0·001) and 70% methotrexate (P = 0·014)], PASI 90 [80% vs. 9% FAEs (P < 0·001) and 39% methotrexate (P < 0·001)] and PASI 100 [41% vs. 4% FAEs (P < 0·001) and 13% methotrexate (P = 0·0041)], as well as sPGA (0,1) and DLQI (0,1). Conclusions: Ixekizumab was superior in inducing PASI 75/90/100, sPGA (0,1) and DLQI (0,1) responses at week 24 compared with methotrexate and FAEs. Safety profiles for all treatments were consistent with prior studies.
