Detailed Summary
This is a Phase 3b, randomized, parallel-group, multicenter, active-controlled, open-label study of the efficacy and safety of infliximab compared with methotrexate (MTX) in the treatment of moderate to severe psoriasis in adults who were diagnosed with moderate to severe plaque-type psoriasis for at least 6 months prior to screening (subjects with concurrent psoriatic arthritis may also be enrolled).

Timeline
Interventions
The infliximab dose will be prepared according to the subject's weight (5 mg/kg). Each intravenous (IV) infusion will be administered over a period of not less than 2 hours. The infusion must be given via a separate line using the administration set with a 1.2 micron filter. Subjects will be infused at Weeks 0, 2, 6, 14, and 22.
Methotrexate will be supplied as 2.5 mg tablets. Subjects are to take 15 mg/week orally for the first 6 weeks of the study. Subjects will be advised to take their MTX as a single dose (weekly) on the same day of the week. If subjects randomized to MTX 15 mg/week experience a \<25% reduction in PASI score at Week 6 (Visit 4) as compared with Baseline, their MTX dose will be increased to 20 mg/week. Subjects will be treated for 22 weeks.
