Condition(s) targeted: Psoriasis
Intervention: excimer vs sham excimer (Device)

The hypothesis of this study is that excimer (308-nm UVB) laser added to either tazarotene
0. 1% gel or acitretin 25 mg daily will lead to improved efficacy of these treatments alone.
The primary objective of this study is to compare the improvement of psoriatic plaques with
and without excimer laser (308-nm UVB) treatment, applied in a randomized and blinded
fashion, in subjects on acitretin 25 mg or tazarotene gel 0. 1% QD. The primary endpoint will
be the comparison between the change in NPF score of plaques treated with excimer laser and
those treated with sham treatment.
The secondary objectives are to compare the number of excimer light treatments and time
necessary to achieve an average lesion assessment score of 0 to 1 in subjects treated with
acitretin 25 mg PO or tazarotene gel 0. 1% QD, and to evaluate adverse events related to
combinations of the study treatments.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: change in the NPF psoriasis score of plaques with the assigned treatment, excimer laser or sham treatment.
Time (days) to achieve an average lesion assessment score of 0 to 1 in subjects treated with acitretin 25 mg PO or tazarotene gel 0.1% QD.
number of excimer light treatments necessary to achieve an average lesion assessment score of 0 to 1 in subjects treated with acitretin 25 mg PO or tazarotene gel 0.1% QD.

Maximum age: N/A.
- Must give written informed consent
- Must be at least 18 years old
