Study Summary

This trial is testing whether a new treatment, narrow band ultraviolet B (NB-UVB) is better than the current standard treatment, psoralen with long wavelength ultraviolet A radiation (PUVA), for hand psoriasis/eczema.

Who is the study for?
This trial is for adults with severe, chronic hand psoriasis or eczema that's symmetrical. It's open to those who've tried topical steroids without full success. Pregnant or breastfeeding individuals, those with photosensitivity disorders, skin cancer, blistering conditions, or impaired sensation in extremities like from diabetic neuropathy are excluded.Check my eligibility
What is being tested?
The study compares two treatments for stubborn hand skin diseases: topical Psoralen Ultraviolet Light A (t-PUVA) and Narrow Band Ultraviolet Light B (NB-UVB). The goal is to see which one is more effective and safer for patients struggling with these long-lasting skin issues.See study design
What are the potential side effects?
Topical PUVA can cause short-term side effects like redness and itching as well as long-term risks such as increased aging of the skin and higher chances of skin cancer. NB-UVB tends to have fewer side effects but may still lead to similar reactions including mild burning or increased pigmentation.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
The primary endpoint will be based on the change in visual cutaneous symptoms as measured by the modified ASI score
Secondary outcome measures
Adverse effects will be assessed every four weeks, including erythema, pruritus, and tanning. This will be assessed using the following scale: 0=none, 1=mild, 2=moderate, 3=severe.

Trial Design

2Treatment groups
Active Control
Group I: Topical PUVAActive Control1 Intervention
This single-blinded randomized bilateral left to right controlled comparison clinical trial of 24 weeks duration will compare the efficacy of NB-UVB to t-PUVA. For each patient one hand will be randomly assigned to receive t-PUVA and the other hand will receive NB-UVB. Each hand will receive treatment with either NB-UVB or topical PUVA three times weekly. Treatment will be performed until complete or almost complete clearing of psoriasis/eczema or until 50 exposures (over 16 weeks) have been reached, whichever comes first.
Group II: NB-UVBActive Control1 Intervention
This single-blinded randomized bilateral left to right controlled comparison clinical trial of 24 weeks duration will compare the efficacy of NB-UVB to t-PUVA. For each patient one hand will be randomly assigned to receive t-PUVA and the other hand will receive NB-UVB. Each hand will receive treatment with either NB-UVB or topical PUVA three times weekly. Treatment will be performed until complete or almost complete clearing of psoriasis/eczema or until 50 exposures (over 16 weeks) have been reached, whichever comes first.
