Abstract

Background
Risankizumab, human immunoglobulin G1λ monoclonal antibody, selectively blocks the p19 subunit of interleukin-23-mediated signaling pathway. Risankizumab has emerged as an effective and well-tolerated therapeutic option for moderate-to-severe psoriasis. However, real-world data on treatment outcomes of risankizumab in Korean patients with psoriasis are limited.
Objective
To investigate the efficacy and safety of risankizumab in Korean patients with moderate-to-severe plaque psoriasis.
Methods
We retrospectively reviewed patients with moderate-to-severe psoriasis who were treated with risankizumab in our hospital from July 2020 to December 2022. A total of 45 patients with psoriasis who were treated with risankizumab for at least 16 weeks were included in this study. Patient demographics, Psoriasis Area and Severity Index (PASI) scores, Investigator’s Global Assessment scores, and adverse events were assessed.
Results
The mean baseline PASI score (13.1±7.7) was significantly decreased after 16 weeks of risankizumab treatment (0.9±1.4) (p＜0.05). Of the 45 patients, 40 showed a PASI 90 response at the last follow-up visit. No serious adverse events were observed. Three patients (6.7%) experienced mild adverse events such as injection site reaction, easy bruising, and headache.
Conclusion
Our real-world data demonstrated that risankizumab treatment is effective and safe in Korean patients with moderate-to-severe plaque psoriasis.
