BACKGROUND: Psoriasis is a chronic inflammatory skin disease with a strong genetic predisposition and autoimmune component that is often treated with immunomodulators such as biologic therapy. Guselkumab is a biologic treatment option that selectively targets the p19 subunit of interleukin (IL)-23; risankizumab is a more recently developed monoclonal antibody of the same class that targets IL-23p19. There is limited research around effective treatment response with intra class switching within IL-23-targeted therapies for the treatment of moderate-to-severe plaque psoriasis.
OBJECTIVES: The purpose is to assess patient response to risankizumab after guselkumab failure for the treatment of plaque psoriasis.
METHODS: A retrospective chart review was conducted for 13 patients meeting inclusion criteria. Physical examination findings were converted to a 5-point static physicians' global assessment (sPGA) score. Baseline, 4-month, and 12-month sPGA scores were assigned from visits immediately prior to and during their course of risankizumab treatment. sPGA scores were analyzed to compare changes between baseline and 4 months and 12 months of therapy.
RESULTS: Patients treated with risankizumab had lower sPGA scores after both 4 and 12 months compared to their baseline sPGA score. 46% of patients met the primary outcome of an sPGA score of 0 or 1 at 4 months of risankizumab, increasing to 90% of patients at 12 months.
CONCLUSIONS: Our findings reflect an improvement in sPGA scores when patients are treated with risankizumab following guselkumab failure. This highlights the benefit of in-class switch to risankizumab when patients with moderate-to-severe plaque psoriasis have failed multiple treatments including guselkumab.
