Efficacy and Safety of Ixekizumab in a Randomized, Double-Blinded, Placebo-Controlled Phase 3b Study of Patients with Moderate-to-Severe Genital Psoriasis
BACKGROUND: Genital psoriasis (GenPs) is a common, debilitating, and difficult to treat manifestation of plaque psoriasis. However, few controlled, interventional studies of GenPs exist. OBJECTIVE: To determine the efficacy of ixekizumab versus placebo in patients with moderate-to-severe GenPs with BSA>/=1%. METHODS: Subjects with moderate-to-severe GenPs (defined as a baseline static Physician's Global Assessment of Genitalia [sPGA-G] score of >/=3) with BSA>/=1% were randomized 1:1 to receive placebo (N=74) or the recommended dosing of ixekizumab (N=75). Major outcomes included the percentage of patients achieving 0 or 1 scores on the sPGA-G (primary endpoint), overall sPGA, GenPs Sexual Frequency Questionnaire (GenPs-SFQ) item 2, and a >/=3-point improvement from baseline on the GenPs itch numeric rating scale. RESULTS: At week 12, ixekizumab was superior to placebo on the sPGA-G 0/1 (73.3% versus 8.1%, p/=1%. The safety profile of ixekizumab was consistent with previous studies in moderate-to-severe plaque psoriasis. This article is protected by copyright. All rights reserved.
