Effectiveness and Safety of Guselkumab for the Treatment of Psoriasis in Real-World Settings at 52 weeks: A Retrospective, Observational, Multicenter Study from China

Real-life studies evaluating the long-term efficacy of guselkumab in moderate-to-severe psoriasis in China are limited and not available.In this real-life study, we retrospectively examined a total of 27 patients with moderate-to-severe psoriasis treated with guselkumab [100 mg, subcutaneous (s.c.)] with a follow-up period of at least 52 weeks in a real-life setting conducted at the Department of Dermatology, Xiangya Hospital, Central South University and Department of Psoriasis, Dalian Dermatosis Hospital. The primary endpoint of the study was long-term effectiveness [reduction of Psoriasis Area and Severity Index (PASI) score, improvement of Dermatology Life Quality Index (DLQI)], safety, and tolerability of guselkumab.Guselkumab treatment decreased the mean PASI score from 12.46 ± 6.34 at baseline to 4.03 ± 3.25 (P < 0.001) and 0.77 ± 1.25 (P < 0.001) at 12 and 52 weeks. At 12 weeks, PASI 75, 90, and 100 response was achieved in 44.4%, 18.5%, and 11.1% of patients, respectively. At 1 year, PASI 75, 90, and 100 response was achieved in 88%, 72%, and 48% of patients, respectively. At 52 weeks, 96% of patients achieved a PASI score of ≤ 3 and 80% of patients achieved DLQI (0/1). No patients withdrewed from the study due to primary or secondary ineffectiveness or failure to adhere to the medication. During the follow-up period, only two adverse events were reported (tinea capitis and diarrhea).Our findings confirm that guselkumab is an appropriate therapeutic option in routine clinical practice, particularly when treating sophisticated patients with comorbidities or who failed to previous biologic therapy.
