Abstract

Introduction: Nail psoriasis is highly prevalent among patients with psoriasis yet remains one of the most challenging areas to treat. To better understand the treatment landscape for psoriatic nail disease, more studies are needed that compare the effectiveness of different biologics for patients with nail psoriasis. This study contributes to this objective by directly comparing the effectiveness of approved biologics in improving nail psoriasis for patients up to month 12 in a real-world setting.

Methods: Psoriasis Study of Health Outcomes (PSoHO) is an ongoing 3-year, prospective, non-interventional cohort study of adults with chronic moderate-to-severe plaque psoriasis initiating or switching to a new biologic. This study assessed the change in modified Nail Psoriasis Severity Index (mNAPSI) score from baseline to months 3, 6 and 12 for 763 patients and compared the effectiveness of anti-interleukin (IL)-17A biologics versus other approved biologics, as well as ixekizumab versus secukinumab, guselkumab, risankizumab and adalimumab. Comparative adjusted analyses used frequentist model averaging (FMA). Least square mean difference (LSMD) in mNAPSI scores are presented as observed.

Results: Irrespective of the severity of nail psoriasis at baseline, the anti-IL-17A cohort had greater mean mNAPSI reductions from baseline compared to the other biologics cohort through month 12, reaching significance at months 3 and 6 in the adjusted analysis. For patients with moderate-to-severe nail psoriasis, ixekizumab showed numerically higher mean reductions in mNAPSI scores compared to all other studied biologics, reaching significance versus guselkumab at all timepoints and risankizumab at month 6.

Conclusion: This real-world study showed that patients with moderate-to-severe psoriasis and any severity of concomitant nail involvement had significantly faster and more substantial improvements in nail psoriasis up to month 6 in the anti-IL-17A cohort compared to the other biologics cohort. Of the individual biologics studied, ixekizumab showed the highest numerical improvements in nail psoriasis at month 12.
