简要总结

This study will evaluate the efficacy, tolerability, and effect on the quality of life of infliximab in adults with moderate-to-severe psoriasis who are resistant to etanercept after 12 weeks of treatment or have failed 24 weeks of treatment with etanercept. Infliximab will be administered as an intravenous infusion of 5 mg/kg at Baseline (Week 0), Visit 3 (Week 2), Visit 4 (Week 6), Visit 6 (Week 14), and Visit 8 (Week 22).

结局指标

主要结局

Psoriasis Area and Severity Index (PASI) 75 Response Rate at Week 10

时间窗: Baseline and 10 weeks

PASI correlates to the physician's assessment of psoriasis symptoms including redness of lesions, thickness of lesions, scaliness of lesions and extent of disease. Each parameter is graded from 0-4, 0 refers to no disease and 4 to severe involvement. The body is divided into 4 areas for scoring (head, arms, trunk to groin, legs to top of buttocks), and the final score ranges from 0-72. The PASI 75 response rate at Week 10 is measured as the percentage of participants who achieved at least 75% improvement from baseline PASI at Week 10.
