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. [ Time Frame: 28 days ] [ Designated as safety issue: No ]
  • The primary safety endpoint is incidence of adverse experiences, including pain and dermatologic/skin toxicity (incidence, severity, frequency, duration and causality). [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Psoriasis Severity Index (PSI) score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Plaque Response score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Pruritus Self-Assessment score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
