Abstract

Background/Objectives: Information is limited on the relationship between skin clearance, resolution of challenging body areas, and improvement of patient-reported outcomes (PROs) in pediatric psoriasis. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for the treatment of moderate-to-severe psoriasis in patients aged 6 to <18 years. This study examines improvement in psoriasis clearance in challenging body areas in pediatric patients relative to health-related quality of life. Methods: Data from the IXORA-PEDS trial (NCT03073200) were analyzed, and changes from baseline were measured for overall Psoriasis Area and Severity Index (PASI), static Physicians' Global Assessment of psoriasis (sPGA), Psoriasis Scalp Severity Index (PSSI), Palmoplantar Psoriasis Area and Severity Index (PPASI), and Nail Psoriasis Severity Index. Rates of Dermatology Life Quality Index (DLQI), or Children's DLQI (CDLQI), scores of 0 or 1 were evaluated using the Cochran-Armitage trend test. Results: Higher rates of DLQI/CDLQI (0,1) scores were significantly associated with greater PASI and PSSI responses at both Week 12 and Week 48 (p <.0001). A significant association was also observed between DLQI/CDLQI (0,1) and sPGA scores (p <.0001). Significantly higher rates of DLQI/CDLQI (0,1) scores were achieved in patients with greater levels of palmoplantar clearance as measured by PPASI at Week 12 (p =.0139), but significance was not sustained at Week 48 (p =.0896). Conclusions: Greater skin clearance and scalp resolution are associated with better PROs over a short-term (12-week) and long-term (48-week) period. This demonstrates that greater improvement of skin clearance and scalp resolution may benefit quality of life in pediatric patients with psoriasis.
