Long-term efficacy and safety of guselkumab in Chinese patients with moderate-to-severe plaque psoriasis

Abstract

BackgroundRandomized controlled trials indicated guselkumab, the first anti-interleukin-23 monoclonal antibody, is efficacious in plaque psoriasis. However, guselkumab's performance in real life is scarcely examined, especially in China.ObjectivesThis work aimed to assess the long-term effectiveness of guselkumab in actual clinical practice in China.MethodsA retrospective study was performed for plaque psoriasis cases administered guselkumab in Shanghai Skin Disease Hospital between January 2020 and September 2022.ResultsA total of 37 patients were included (29 men, 78.4%), with a mean follow-up period of 72.3 ± 26.7 weeks (range of 12–108 weeks). At baseline, clinical examination revealed a mean PASI of 12.3 ± 7.1, a mean BSA of 17.1 ± 18.1, and a mean DLQI of 7.7 ± 4.3. Twenty-two (62.9%) and 17 (48.6%) cases achieved PASI 90 and PASI 100 responses at week 28. From weeks 60 to 92, >80% of cases achieved PASI 90 and PASI 100 responses. Regarding safety, no cases of serious AEs were recorded. A total of nine cases (24.3%) had different abnormal results in HBV markers, and two were T-SPOT positive. There was no hepatitis B virus or tuberculosis outbreak in these patients.ConclusionThis real-life study confirmed the long-term efficacy and safety of guselkumab in daily clinical practice.
