Background: Guselkumab is a monoclonal antibody that selectively blocks the p19 subunit of interleukin-23. It has shown good efficacy and safety profile in several clinical trials of plaque psoriasis. However, studies on the efficacy of guselkumab in patients treated with other biologics are lacking.
Objective: We aimed to investigate the efficacy and safety profile of guselkumab in patients with moderate-to-severe plaque psoriasis. We also compared the efficacy of guselkumab between biologic-naive (Bio-Naive) and biologic- experienced (Bio-Ex) patients.
Methods: This multicenter, retrospective study included 72 patients treated with guselkumab. The patients’ clinical characteristics and psoriasis area and severity index (PASI) scores were recorded at each visit. The PASI90 and PASI100 responses and mean PASI scores were compared between the Bio-Naive and Bio-Ex groups.
Results: Fifty-five Bio-Naive patients and 17 Bio-Ex patients were included in the study. At week 20, there were no significant differences in the PASI90 (64.2% vs. 53.8%) and PASI100 (28.3% vs. 15.4%) responses between the groups.
However, at weeks 36 and 44, the PASI90 response (week 36: 89.2% vs. 36.4% and week 44: 97.8% vs. 63.6%) and the PASI100 response (week 36: 64.9% vs. 18.2% and week 44: 68.9% vs. 27.3%) were significantly higher in the Bio-Naive group (p＜0.05). There were no differences in PASI90 and PASI100 responses between the groups in terms of other clinical characteristics and comorbidities at week 20.
Conclusion: The efficacy of guselkumab remained consistent among patients in whom other biologics had failed.
However, the efficacy was slightly lower in the Bio-Ex group than in the Bio-Naive group.
