Trial Outcomes & Findings for Infliximab in High Need Versus Low Need Psoriasis Patients: The IHELP Study (Study P04320)(COMPLETED) (NCT NCT00254982)

NCT ID: NCT00254982

Last Updated: 2015-10-12

Results Overview

PASI75 response is defined as participants who achieved at least a 75% improvement in PASI score from Baseline to Week 22. The PASI is a system used for assessing and grading the severity of psoriatic lesions and their responses to therapy. The PASI produces a numeric score that can range from 0 to 72 (the higher the number, the worse the disease).

Measure
Group 1 (High-need)
Adult participants with moderate to severe plaque psoriasis who were either not controlled by, or were intolerant to or had contraindications to at least two currently available systemic therapies (eg, photochemotherapy, cyclosporine, methotrexate, oral retinoids, fumaric acid esters, efalizumab, etanercept). Infliximab 5 mg/kg was given as an induction regimen at week 0, 2, and 6 weeks after the first infusion and then at week 14.
Group II (Low-need)
Adult participants with moderate to severe plaque psoriasis who had undergone pretreatment with no more than one currently available systemic therapy (eg, photochemotherapy, cyclosporine, methotrexate, oral retinoids, fumaric acid esters, efalizumab, etanercept). Infliximab 5 mg/kg was given as an induction regimen at week 0, 2, and 6 weeks after the first infusion and then at week 14.

PRIMARY outcome

Timeframe: Baseline and Week 22

Population: Per Protocol Population - All participants in the intent to treat population who completed the study without major protocol violations. For missing data, the last observation carried forward (LOCF) was applied.

PASI75 response is defined as participants who achieved at least a 75% improvement in PASI score from Baseline to Week 22. The PASI is a system used for assessing and grading the severity of psoriatic lesions and their responses to therapy. The PASI produces a numeric score that can range from 0 to 72 (the higher the number, the worse the disease).
