Phase IV Study: Vunakizumab Efficacy and Safety in Moderate-to-severe Plaque Psoriasis

This is a multicenter, prospective, observational study of 1516 patients with moderate-to-severe chronic plaque psoriasis to evaluate the efficacy and safety of vunakizumab in patients with moderate-to-severe chronic plaque psoriasis. Approximately 50-100 clinical trial centers are planned to participate in the study. The study consisted of a 7-day screening period, a 52-week treatment period and an 8-week safety follow-up period. The recommended dose of vunakizumab is 240 mg (120 mg in two injections), with subcutaneous injection at week 0, 2, and 4, followed by a dose every 4 weeks and a final injection at week 48 (the actual treatment regimen is based on the clinician's recommendation). After the corresponding assessment at 52 weeks, an 8-week safety follow-up period was entered until the end of the study.
