Primary UVB-311nm and Adalimumab in Psoriasis Patients

Not Applicable

Completed

• Conditions: Psoriasis
• Interventions: Radiation: UVB-311nm

• Registration Number: NCT00638261
• Lead Sponsor: Medical University of Graz

Brief Summary

Adalimumab, a fully human anti-tumor necrosis factor (TNF) monoclonal antibody has been approved for the treatment of moderate to severe psoriasis. However, in a portion of cases adalimumab does not induce reduction of psoriasis area and severity index (PASI) of 75% or greater, now being considered as gold standard for treatment efficacy. In this study we aim to determine in a randomized half-side comparison whether initial narrowband UVB-311nm phototherapy accelerates and improves the clearance of skin lesions in adalimumab-treated patients.

Detailed Description

Patients with moderate to severe psoriasis who are scheduled to receive a standard treatment course of adalimumab (loading dose of 80 mg and thereafter 40 mg s.c. biweekly) are exposed to UVB-311nm phototherapy on a randomized body half (left or right; head exempt) 3 x per week for six weeks and/or until complete response (defined as reduction in PASI to \< 3). PASI score, patient visual analogue score (VAS) for therapeutic response, and patient VAS for severity of skin lesions is assessed weekly; and at follow-up visits at month 3, 6, and 12. Paired Wilcoxon testing for differences in PASI and patient VAS scores is done; Fischer exact test is applied to determine differences in complete remission, PASI reduction \> 90%, \> 75% and/or 50% between body sites.
