Brief Summary

The primary objective of this study is to evaluate the efficacy and safety of HS-20137 in the treatment of participants with moderate to severe plaque psoriasis.

Detailed Description

HS-20137 is an antibody targeting IL-23, which were recommended biologic agents for the treatment of patients with moderate-to-severe psoriasis. This is a randomized, double-blinded, placebo-controlled phase 3 study, including a 4 weeks screening period, a 52 weeks double-blinded period (placebo-control period in the first 16 weeks) and a 8 weeks follow-up period (total 60 weeks). The hypothesis is that HS-20137 will be more effective in treatment of psoriasis than placebo and well tolerated. Participants with moderate-to-severe plaque psoriasis will be included in this study and received HS-20137 200mg or placebo in week 0, 4, 8 in placebo-control period and then HS-20137 200mg every 8 or 12 weeks thereafter.
