- Subjects who have received topical antipsoriatic therapy (including corticosteroids, tar, anthralin or Vitamin D analogs) to the study plaque areas within 14 days of study initiation.
- Subjects who have received agents posing a clinically significant risk of photosensitivity reaction within 5 half-lives of study initiation.
- Subjects who have received any approved or investigational biologic drug therapy for psoriasis within 90 days or 5 half-lives of study initiation.
- Subjects who have participated in a clinical research study within 28 days of study initiation.
- Subjects with a history of porphyria, systemic lupus erythematosus or xeroderma pigmentosum.
- Subjects with clinical conditions that, in the opinion of the Investigator may pose a health risk to the subject by being involved in the study or detrimentally affect regular follow-up of the subject.

Outcomes
Primary Outcome Measures
The primary efficacy endpoint is "Treatment Success," a static endpoint assessed at Day 29 after initial PH-10 treatment and defined as 0 or 1 on all Psoriasis Severity Index (PSI) components and 0 or 1 on the Plaque Response scale.
The primary safety endpoint is incidence of adverse experiences, including pain and dermatologic/skin toxicity (incidence, severity, frequency, duration and causality).
Secondary Outcome Measures
Psoriasis Severity Index (PSI) score changes at each visit from Day 1 pre-treatment.
Plaque Response score changes at each visit from Day 1 pre-treatment.
Pruritus Self-Assessment score changes at each visit from Day 1 pre-treatment.

Brief Summary
PH-10 is an aqueous hydrogel formulation of rose bengal disodium (RB) for topical administration to the skin, and is being studied for the treatment of cutaneous skin disorders, specifically psoriasis and atopic dermatitis. This multicenter phase 2 study of subjects randomized sequentially by center to one of four treatment cohorts will assess efficacy and safety of topical PH-10 applied once daily to areas of mild to moderate plaque psoriasis.
