Vascular Inflammation in Psoriasis-Ustekinumab (VIP-U)

Study Overview
=================
Brief Summary
-----------------
The VIP-U Study is a clinical trial designed to investigate the effect of ustekinumab (Stelara) and placebo on reducing vascular inflammation and cardiometabolic risk biomarkers in patients with moderate to severe psoriasis. This study will look for systemic vascular inflammation in study participants with a test called FDG PET/CT (fluorodeoxyglucose-positron emission tomography/computed tomography). The study will also look for cardiometabolic identifiers (heart disease and metabolic factors) in blood samples, including markers of high cholesterol, cholesterol efflux function (the ability of cholesterol to move in the body), metabolic factors, and inflammation. The study will also examine the effects of ustekinumab compared to placebo on psoriasis activity, severity and safety.

| Number of Participants Achieving PASI75 (75% or Greater Reduction in PASI Score) | To assess the effects of ustekinumab, as compared to placebo, at Week 12 (RCT period) in patients with moderate to severe psoriasis on PASI75, and assess global change at end study (Week 52 for Ustekinumab arm, Week 64 for Placebo arm; active treatment period). Binary measure of change in psoriasis activity; 75% or greater reduction in PASI score compared to baseline. | Baseline - Week 12; Baseline - End of Study Visit (Week 52 or Week 64) | 
| Number of Participants Achieving PASI90 (90% or Greater Reduction in PASI Score) | To assess the effects of ustekinumab, as compared to placebo, at Week 12 (RCT period) in patients with moderate to severe psoriasis on PASI90, and assess global change at end study (Week 52 for Ustekinumab arm, Week 64 for Placebo arm; active treatment period). Binary measure of change in psoriasis activity; 90% or greater reduction in PASI score compared to baseline. | Baseline - Week 12; Baseline - End of Study Visit (Week 52 or Week 64) | 
| Number of Participants Achieving Physician Global Assessment (PGA) Clear/Almost Clear | To assess the effects of ustekinumab, as compared to placebo, at Week 12 (RCT period) in patients with moderate to severe psoriasis on PGA clear/almost clear, and assess global change at end study (Week 52 for Ustekinumab arm, Week 64 for Placebo arm; active treatment period). Binary measure of psoriasis disease activity at measurement time points; Physician Global Assessment score <1.5 (clear/almost clear) | Baseline - Week 12; Baseline - End of Study Visit (Week 52 or Week 64) | 
| Change in Patient-Reported Outcomes: MEDFICTS | To assess the effects of ustekinumab, as compared to placebo, at Week 12 (RCT period) in patients with moderate to severe psoriasis on MEDFICTS, and assess global change at end study (Week 52 for Ustekinumab arm, Week 64 for Placebo arm; active treatment period). MEDFICTS (Meats, Eggs, Dairy, Fried foods, fat In baked goods, Convenience foods, fats added at the Table, and Snacks), a brief dietary assessment instrument, has been provided as part of the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) guidelines as a free tool to use for proper cardiovascular diet assessment. The questionnaire yields a continuous score (ranging from 0 to 216), with a score of <40 indicating adherence to the Therapeutic Lifestyle Changes (TLC) diet (intake of <7% of energy from saturated fat, <30% of energy from total fat, and <200 mg dietary cholesterol/day). | Baseline - Week 12; Baseline - End of Study Visit (Week 52 or Week 64) | 
| Change in Patient-reported Physical Activity Assessments: IPAQ | To assess the effects of ustekinumab, as compared to placebo, at Week 12 (RCT period) in patients with moderate to severe psoriasis on IPAQ, and assess global change at end study (Week 52 for Ustekinumab arm, Week 64 for Placebo arm; active treatment period). IPAQ is an instrument designed primarily for population surveillance of physical activity among adults with activity measured in metabolic equivalent (MET)-minutes per week. | Baseline - Week 12; Baseline - End of Study Visit (Week 52 or Week 64) |
