Fumaric Acid Versus Fumaric Acid Plus Narrow Band Type B Ultraviolet (UVB) for Psoriasis

Fumaric Acid Esters Versus Fumaric Acid Esters Plus Narrow Band Type B Ultraviolet (UVB) in Patients With Severe Plaque Psoriasis

The main objective of the study is to evaluate the additional effect of a narrow band Type B Ultraviolet (UVB) therapy on the treatment of severe plaque psoriasis with fumaric acid esters (FAE) in comparison to FAE monotherapy. The secondary objectives are to evaluate the effect of an additional narrow band UVB therapy on the cumulative FAE dose required to reach Psoriasis Area and Severity Index (PASI) 75 in comparison to FAE monotherapy and to evaluate whether a leukopenia and lymphopenia frequently occurring during the FAE treatment is a positive predictive factor for the treatment response.
