简要总结
The purpose of this study is to determine the superiority and efficacy of infliximab induction therapy in chinese participants with moderate to severe plaque-type psoriasis (scaly skin rash) compared with placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial).
详细描述
This is a double-blind (neither physician nor participant knows the treatment that the participant receives), multicenter (when more than one hospital or medical school team work on a medical research study) and placebo-controlled study of infliximab in participants with moderate to severe plaque-type psoriasis. All the eligible participants will be randomly assigned to infliximab and placebo groups. The infliximab group will receive 5 milligram per kilogram (mg/kg) infliximab infusions (a fluid or a medicine delivered into a vein by way of a needle) intravenously (into a vein) at Week 0, 2 and 6 in the induction treatment phase followed by maintenance regimen of the intervention every 8 weeks up to 26 weeks. Placebo infusions will also be given at Week 10, 12 and 16. The placebo group will receive placebo infusion at Week 0, 2, 6, 14 and 22. At Week 10, participants in placebo group will then receive infliximab induction therapy. Efficacy of the participants will primarily be evaluated by percentage of participants who achieve a Psoriasis Area and Severity Index 75 (PASI) response at Week 10. Participants' safety will be monitored throughout the study.

- •Participants who are pregnant, nursing or planning to become pregnant within one year while enrolled in the study
- •Participants who had previous treatment with infliximab
- •Participants who have received agents targeted at reducing tumour necrosis factor or any biologic treatment within the previous 3 months
- •Participants who have used any investigational drug within the previous 4 weeks or 5 times the half-life of the investigational agent, whichever is longer
研究组 & 干预措施
Infliximab
5 milligram per kilogram (mg/kg) infusion (a fluid or a medicine delivered into a vein by way of a needle) of infliximab administered intravenously (into a vein) at Week 0, 2 and 6 followed by maintenance regimen of 5 mg/kg infliximab at Week 14 and 22. Placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial infusion), matched to infliximab will be given at Week 10, 12 and 16. Total duration of treatment will be 26 weeks.
干预措施: Placebo (Drug)

Placebo
Placebo infusion, matched to infliximab will be given intravenously at Week 0, 2 and 6. At Week 10, 12 and 16, participants will receive 5 mg/kg infliximab intravenously. Placebo infusion will be again given at Week 14 and 22. Total duration of treatment will be 26 weeks.

结局指标
主要结局
Percentage of Participants Who Achieved a Greater Than Equal to 75 Percent Response in Psoriasis Area and Severity Index (PASI)
时间窗: Week 10
The PASI score is based on the assessment of the erythema (e), induration (I), scaling (S), and the body is divided into 4 regions head, trunk, upper extremities, lower extremities. The assessment was done on 4-point scale (where, 0 = none, 1 = slight, 2 = moderate, 3 = severe, and 4 = very severe). The total possible score ranges from 0 (no disease) to 72 (maximal disease). Participants with no less than 75 percent relative Baseline improvement in the PASI scores are considered to be PASI 75 responders.
次要结局
- Change From Baseline in Dermatology Life Quality Index (DLQI) at Week 10(Baseline and Week 10)
- Percentage of Participants With Static Physician Global Assessment (PGA) Score Less Than Equal to 1 at Week 10(Week 10)
