Primary Outcome Measures:
  • Change from baseline in visual assessment scores at 3 months [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
    The visual assessment evaluates seven clinical signs: erythema, edema, wheal vesiculation, ulceration, hemorrhage, purpura, and crusting. Each sign is assigned a score of 0 to 3, where a score of 0 is associated with no expression of the clinical sign and a better outcome, and a score of 3 is associated with severe expression of the clinical sign and a worse outcome.

Estimated Enrollment: 20
Study Start Date: October 2012
Estimated Study Completion Date: May 2016
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ingenol Mebutate
Ingenol Mebutate applied to one side of face with skin lesions
