|Official Title:||Randomized Controlled Trial of 308 nm Excimer Laser for Treatment of Nail Psoriasis|
|Study Start Date :||January 2014|
|Actual Primary Completion Date :||December 2014|
|Actual Study Completion Date :||January 2015|
Experimental: active excimer laser
308 nm excimer laser treatment: treatment with the laser by a dose protocol with increasing output.
Device: 308 nm excimer laser
Biweekly treatments with 308 nm excimer laser for a total of 8 weeks
Sham Comparator: Sham excimer laser
Sham 308 nm excimer laser treatment: laser dose was administered with a cap that blocks all active UV passing through the device, therefore is a placebo, but because the procedure is the same, maintains a blind.
Device: Sham laser
Sham laser treatment to the control side biweekly for a total of 8 weeks.
- Modified NAPSI Score (Nail Psoriasis Severity Index) [ Time Frame: at 16 weeks ]This is an instrument that scores nail psoriasis severity. Severity for each nail is measured on a scale of 0-13, where crumbling, pitting, onycholysis and oil spots together are each graded 0-3, and other features (leukonychia, splinter hemorrhages, hyperkeratosis, and red spots in lunula) are scored 0 (absent) or 1 (present). Higher score indicates more severe nail psoriasis with 13 being the most severe and 0 being no nail disease present.
- Patient Assessment of Nail Psoriasis Activity [ Time Frame: at 16 weeks ]this is a subjective patient reported scale, 0-100, where 100 is the most severe global assessment of the patient's nail psoriasis, and 0 is clear (no nail disease present).
