Details and patient eligibility
About
The purpose of this study is to assess the effect of adalimumab (Humira), when compared to NB-UVB (narrow-band ultraviolet B) phototherapy or placebo (an inactive substance that may resemble an active substance but has no medical value) injection. The study will compare the effects of each on systemic inflammation and cardiovascular disease risk factors in subjects diagnosed with moderate to severe psoriasis.
This study will look for systemic vascular inflammation in subjects with a test called FDG-PET/CT (Fluorodeoxyglucose-positron emission tomography/computed tomography). The study will also look for cardio metabolic (heart disease and metabolic factors such as diabetes) identifiers in the blood. A blood sample will be taken that will look for these markers identifying high cholesterol, cholesterol efflux function (the ability of cholesterol to move in the body), metabolic factors, and inflammation.
This study will also assess the effect of adalimumab (Humira), when compared to NB-UVB phototherapy or placebo injection on psoriasis activity and severity. The study will also compare the safety of adalimumab (Humira) to NB-UVB phototherapy or placebo injection. This study will also evaluate subjects' reported outcomes through a questionnaire that will assess quality-of-life in subjects living with psoriasis.

-
Able and willing to give written informed consent and to comply with requirements of this study protocol.
Exclusion criteria
-
Previous adverse event following exposure to a TNF-alpha antagonist and/or UV phototherapy that led to discontinuation of either of these therapies and contraindicates future treatment.
-
Previous lack of response to a TNF-alpha antagonist and/or UV phototherapy that led to discontinuation of either of these therapies.
-
Diagnosis of erythrodermic psoriasis, generalized or localized pustular psoriasis, medication-induced or medication-exacerbated psoriasis, or new onset guttate psoriasis.
-
Diagnosis of other active skin diseases or skin infections (bacterial, fungal, or viral) that may interfere with evaluation of psoriasis.
-
Cannot avoid UVB phototherapy for at least 14 days prior to the Baseline (Week 0) visit.
-
Cannot avoid psoralen-UVA phototherapy for at least 30 days prior to the Baseline (Week 0) visit and during the study.
-
Cannot discontinue systemic therapies for the treatment of psoriasis, or systemic therapies known to improve psoriasis, during the study:
-
Systemic (investigational or marketed) therapies must be discontinued at least 30 days prior to the Baseline (Week 0) visit except for biologics.
