Phase 2

Completed

• Conditions: Psoriasis
• Interventions: Biological: Infliximab

• Registration Number: NCT00687362
• Lead Sponsor: Merck Sharp & Dohme LLC

Brief Summary

Middle Eastern subjects with moderate-to-severe chronic plaque psoriasis will be administered infusions of infliximab (Remicade) at 5 mg/kg of body weight at Weeks 0, 2, 6, 14, and 22. The safety and efficacy of infliximab monotherapy will be evaluated.

Infliximab 5 mg/kg	Infliximab	Infliximab 5 mg/kg of body weight given as an infusion at Weeks 0, 2, 6, 14, and 22.

Primary Outcome Measures

Name	Time	Method
Psoriasis Area and Severity Index 75 (PASI75) Response at Week 10	10 weeks	PASI 75 response is defined as participants who achieved at least a 75% improvement in PASI score from Baseline to Week 10.; The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. The PASI produces a numeric score that can range from 0 to 72 (the higher the number, the worse the disease).
