Efficacy assessments will include inflammatory and non-inflammatory lesion counts and investigator global assessments (IGA). Tolerability and safety assessments include cutaneous tolerability evaluation, adverse event collection, physical exams, and laboratory studies. Subjects will return for post-baseline evaluation at Weeks 2, 4, 8, and 12.
