Luma Light System Proof of Concept Study in Subjects With Mild to Moderate Psoriasis

A Proof of Concept, Investigator Blinded Study to Evaluate the Efficacy and Safety of a Novel Combination of a Home Narrow Band Ultraviolet B (NBUVB) Lamp With an Occlusive Dressing in Adult Subjects With Mild to Moderate Psoriasis Vulgaris

This is a proof of concept, investigator blinded study to evaluate the efficacy and safety of a novel combination of a home narrow band ultraviolet B (NBUVB) lamp with an occlusive dressing in adult subjects with mild to moderate psoriasis vulgaris. Four interpatient arms will be used to compare the efficacy of combination of NBUVB with an occlusive dressing to the light alone and to dressing alone and no treatment. Ten patients will be enrolled in this 6 weeks study.
