结局指标
主要结局
For the Fixed Interval Group and the Start of Relapse (SoR) Group, the Percentage of Participants (Who Responded to Treatment at Week 12) Maintaining a 75% Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 52
时间窗: Week 40 , week 52
PASI: Combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section(head: 0.1, arms: 0.2 body: 0.3 legs: 0.4)
