Phase 4

Completed

Conditions: Psoriasis
Cardiovascular Diseases

Interventions: Drug: Apremilast

Registration Number: NCT03082729

Lead Sponsor: University of Pennsylvania

Brief Summary: The purpose of the VIP-A study is to determine the effect of apremilast on aortic vascular inflammation, cardiometabolic biomarkers and body composition in patients with moderate-severe psoriasis.

Detailed Description: The primary objectives of this study are to determine the effect of apremilast on aortic vascular inflammation, cardiometabolic biomarkers and body composition in patients with moderate-severe psoriasis. Fluorodeoxyglucose (FDG) - positron emission tomography (PET)/computed tomography (CT) will be used to assess vascular inflammation, with multi-volumetric product, tissue-to-background ratio and total atherosclerotic burden, and body composition via volumetric quantification. This is a year-long, single arm, open label study.

DRI is a nuclear magnetic resonance spectroscopy (NMR)-derived multimarker score (values 1-100) that predicts a patient's risk of developing type 2 diabetes mellitus (T2D) independent of glycemic status.

Changes in Cardiometabolic Markers Between Week 52 and Earlier Time Points (Baseline and Week 16): Cholesterol Efflux Capacity	After the completion of week 52 visit by all study participants.	Cholesterol Efflux Capacity is a marker of lipid function and metabolism. The ability to promote cholesterol efflux from macrophages is a classic function of HDL that is thought to be an important mechanism by which HDL protects against atherosclerosis. HDL cholesterol efflux capacity assays are performed based on published methods using J774 cells derived from a murine macrophage cell line (Mehta NN Atherosclerosis 2012). Efflux is calculated as a unitless measure by using the following formula: \[(µCi of 3H-cholesterol in media containing apoB-depleted subject plasma - µCi of 3H-cholesterol in plasma-free media) / (µCi of 3H-cholesterol in media containing apoB-depleted pooled control plasma-µCi of 3H-cholesterol in pooled control plasma-free media)\]. Cholesterol efflux capacity is inversely correlated with incidence of cardiovascular events (i.e. higher cholesterol efflux capacity is better for patients).
