The UPDATE Trial (Uvb Phototherapy in Dermatology for ATopic Eczema)
Study Details
Study Description
Brief Summary
The goal of this randomized controlled trial is to study the (cost)effectiveness of NB-UVB phototherapy in patients with atopic eczema/atopic dermatitis.
Half of the participants will undergo a course of NB-UVB phototherapy of 8-16 weeks and apply optimal topical therapy (OTT) for a minimum of 3 months. Researchers will compare the outcomes of this group with the other half of participants that apply OTT only.

Detailed Description
Atopic eczema (AE) is a chronic fluctuating dermatological disease characterized by a pruritic inflammation of the skin. The condition poses a high global (financial) burden. One of the therapeutic options of AE is phototherapy, with narrowband UVB (NB-UVB) being the most common. The evidence of the (cost-)effectiveness of NB-UVB, however, is scarce and of low quality.
The objective of this pragmatic multicenter single blinded randomized controlled trial is comparing the effectiveness and cost-effectiveness of narrowband ultraviolet B with optimal topical therapy (NB-UVB+OTT) versus OTT at 3 months in adult patients with insufficient control of their AE with standard topical treatment, for whom dermatologist and patient jointly believe that NB-UVB or OTT is needed.
Participants that are randomized into the NB-UVB+OTT group will receive an NB-UVB course (at home or at the outpatient clinic) for at least 8 and up to 16 weeks, combined with OTT for at least 3 months. Participants in the control group (OTT group) will apply OTT for at least 3 months. Visits will occur at baseline and 1-3-6-9-12 months after start. At baseline, patient information is collected including an evaluation of medical history and a physical examination to assess Fitzpatrick skin type and physician-reported clinical signs. During each visit patients are asked to fill out questionnaires. Risks are expected to be as in daily practice.
Primary study parameters/outcome of the study is the percentage of patients with EASI50 (a decrease of the Eczema Area and Severity Index of 50%) at 3 month follow-up. Secondary study parameters/outcome of the study include delta EASI, physician-reported clinical signs, patient-reported symptoms, quality of life, long-term control, cost-effectiveness, side effects at 1-3-6-9-12 months, quantity and potency topical steroid usage, time to starting systemic therapy, patient satisfaction with received treatment, percentage of patients reaching Treatment Target goals and percentage of drop-outs with reasons at 3-6-9-12 months.
