Detailed Description

This study was a multicenter, parallel, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy ,safety, tolerance, and pharmacokinetics (PK) of different SHR-1314 dosing regimens in moderate to severe chronic plaque psoriasis in adults.


  • Biological: IL-17A Antagonist
    • SHR-1314 subcutaneous injection
  • Biological: Placebos
    • placebo subcutaneous injection to maintain consistency and to prevent blindness

Arms, Groups and Cohorts

  • Active Comparator: Treatment group A
    • SHR-1314 low dose short intervals of subcutaneous injection
  • Active Comparator: Treatment group B
    • SHR-1314 high dose long intervals of subcutaneous injection
  • Active Comparator: Treatment group C
    • SHR-1314 high dose short intervals of subcutaneous injection
  • Placebo Comparator: Placebo group
    • Placebo was subcutaneously injected into the 16 weeks turnover SHR-1314 subcutaneous injection

Clinical Trial Outcome Measures

Primary Measures

  • Proportion of subjects reach to PASI 75 response at 16 weeks
    • Time Frame: 16 week
    • Proportion of subjects with a Psoriatic Area and Severity Index (PASI) score improved by at least 75% (to achieve a PASI 75 response) relative to the baseline PASI score at Week 16

Secondary Measures

  • Proportion of subjects achieving PASI 90 response at week 16
    • Time Frame: 16 week
    • Proportion of subjects with a Psoriatic Area and Severity Index (PASI) score improved by at least 90% (to achieve a PASI 90 response) relative to the baseline PASI score at Week 16 will be evaluated.
