摘要
Background:There have been few real-life dose-comparing studies on the efficacy and safety of secukinumab in Chinese patients with plaque psoriasis.We conducted a real-life cohort study to investigate the efficacy and safety of secukinumab 150 and 300 mg in Chinese patients with moderate-to-severe plaque psoriasis.Methods:A total of 106 patients with moderate-to-severe plaque psoriasis were included in this study.Patients received either secukinumab 150 mg or secukinumab 300 mg according to patients’weights and severity of psoriasis.The treatment continued for at least 24 weeks.The efficacy was evaluated by improvement in the psoriasis area and severity index(PASI)scores.The safety was also analyzed.Results:Fifty-nine patients(55.7%)were treated with secukinumab 300 mg and 47 patients(44.3%)were treated with secukinumab 150 mg.After 12-week treatment,PASI75/90/100 responses were achieved in 100%,97.8%,and 95.7%of patients,respectively,in secukinumab 150 mg group,and the efficacy was maintained to week 24.In secukinumab 300 mg group,PASI75/90/100 responses were achieved in 93.2%,81.4%,and 76.3%of patients,respectively,at week 12.In this group,PASI75/90/100 responses reached 91.5%,86.4%,and 79.9%,respectively,at week 24.Biologic-experienced patients had lower responses than biologic-naïve patients.Secukinumab 150 and 300 mg were well tolerated.Five patients discontinued treatment due to poor response,adverse event,or economic reasons.Conclusions:This real-life study demonstrated that high PASI 90 and PASI 100 responses were achieved in Chinese psoriasis patients receiving secukinumab 150 or 300 mg.Biologic-naïve was associated with better clinical efficacy.
