Assessing Comparative Efficacy of Biologics for the Treatment of Psoriasis With Nail Involvement: A Systematic Review

Abstract

Background Despite recent advances in biologics, there is a lack of significant evidence regarding the comparative efficacy of biologics in treating more resistant features of psoriasis, namely nail psoriasis. A systematic review synthesizing data from multiple studies is efficacious in assessing the comparative efficacy among biologics for the treatment of nail psoriasis. Objective To evaluate and compare the efficacy of biologics for the treatment of nail psoriasis. Methods Utilizing PRISMA guidelines, a systematic literature review was conducted using the Pubmed database on November 16, 2022. Studies selected were phase 3 or 4 randomized clinical trials, clinical studies, or other randomized trials with data on the treatment with biologics for adults with nail psoriasis. Results Sixteen studies meeting inclusion criteria were included for analysis. At 24 weeks, the highest mean NAPSI percent improvement achieved at week 24 was by brodalumab (76.9%) followed by etanercept (74%) and ixekizumab (70.5%) while the biologics achieving the greatest proportion of NAPSI 0 were adalimumab (44.6%) and ixekizumab (41%). Conclusions This study helps elucidate the comparative efficacy of biologics for the treatment of nail psoriasis. This review suggests that brodalumab and etanercept are associated with the highest percent improvement in nail psoriasis while adalimumab and ixekizumab are associated with the greatest probability of complete nail resolution.
