Effectiveness of ixekizumab for the treatment of moderate-to-severe plaque psoriasis with involvement of difficult-to-treat areas: A 52-week multicenter retrospective study

Abstract

Biological drugs have dramatically changed the approach to treating moderate-to-severe plaque psoriasis, achieving excellent skin clearance and safety outcomes. However, the management of difficult-to-treat areas (e.g., scalp, palms/soles, nails, and genitalia) still represents a challenge in psoriasis treatment. Data in the literature on difficult-to-treat sites are limited and, frequently, no specific analysis is performed during clinical trials. We conducted a 52-week, retrospective study to evaluate the effectiveness of ixekizumab in 120 patients with moderate-to-severe plaque psoriasis of at least one difficult-to-treat area (scalp, palmoplantar surfaces, nails, and genitalia). Ninety-nine patients had scalp psoriasis, 35 had involvement of the palms or soles, 27 were affected by genital psoriasis, and 22 patients reported involvement of the nails. After 1 year of treatment, 96% of patients with scalp involvement, 95.6% of patients with palmoplantar psoriasis, 95.2% of patients with genital psoriasis, and 85% of patients with nail involvement achieved a site-specific Physician's Global Assessment of 0 or 1 (clear or almost clear). No serious adverse events were observed during the study. Our study supports the effectiveness of ixekizumab in plaque psoriasis involving difficult-to-treat sites.
