Psoriasis is a chronic hyperproliferative and inflammatory skin disease with its major subtype, chronic plaque-type psoriasis, affecting approximately 2% of individuals in Western populations. It may lead to heavily disfiguring skin involvement, and it is associated with disabling joint disease (psoriatic arthritis, PSA). Psoriasis has a strong genetic component as evidenced by high familial association and twin studies.

Exclusion criteria
Exclusion criteria: • Exclusion criteria as given in national guidelines (see enclosure); (http://www.uni-duesseldorf.de/AWMF/ll/013-001.htm) and summary of product characteristics • Patient with evidence of any skin condition that would interfere with the evaluation of psoriasis; • Use of FAE or other any biologic agent such as etanercept, infliximab and adalimumab within 4 weeks and 12 weeks prior to Visit 1, respectively • Patients who are considered potentially unreliable or where it is envisaged the patient may not consistently attend scheduled study visits • Patients who are unable to complete a patient diary or complete questionnaires on paper • Patients with any other condition or prior/current treatment, which in the opinion of the investigator renders the patient ineligible for the study schedule. • Pregnancy or breast feading women
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Primary objectives 1. To evaluate the efficacy of TNF?-inhibitor agents, etanercept, adalimumab, infliximab and fumaric acid ester (FAE) in a sample of adult patients with chronic plaque psoriasis ;Secondary Objective: Secondary objectives 2. To identify clinical and metabolomic markers that underlie variability in response to therapy 3. To identify metabolomic signatures associated with psoriasis 4. To identify possible treatment-specific metabolomic signatures ;Primary end point(s): The primary aim of this study is to evaluate the efficacy of various systemic treatments, i.e. TNF?-inhibitor agents (etanercept, adalimumab, infliximab) and fumaric acid ester (FAE). ;Timepoint(s) of evaluation of this end point: 3 Month | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: 3 Month;Secondary end point(s): The secondary aim is to analyse metabolic profiles as well as expression data in patients with chronic plaque psoriasis a) before and during systemic therapy with FAE or TNF-inhibiting agents (etanercept, adalimumab and infliximab) and b) as compared to population-based controls. It is anticipated, to get insights into mechanisms of anti-TNF drug action and response as well as first indications for metabotypes that are associated with psoriasis. In addition, genetic variants correlated to these metabotypes might be identified. Existing data on metabolic profiles and genome-wide (1000k) SNP data from 2000 adults from the population-based KORA studies will be utilised. | — |
