Is this trial a fit for you?

Likely a good fit

Probably not a fit

Patients with contraindications for NB-UVB or those currently on systemic therapies for atopic eczema may not benefit from this study.

What this trial studies

This clinical trial aims to assess the cost-effectiveness of narrowband UVB (NB-UVB) phototherapy in treating adults with atopic eczema who have not achieved sufficient control with standard topical treatments. Participants will be randomly assigned to receive either NB-UVB phototherapy combined with optimal topical therapy (OTT) for 8-16 weeks or to apply OTT alone for a minimum of 3 months. The study will involve multiple follow-up visits to evaluate the effectiveness of the treatments through questionnaires and clinical assessments. The goal is to provide robust evidence regarding the benefits of NB-UVB phototherapy for this patient population.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from atopic eczema.

How similar studies have gone: Previous studies have shown varying degrees of success with phototherapy approaches, but the specific cost-effectiveness of NB-UVB remains under-researched.
