Calcipotriene is a vitamin D3 analog that has been used as topical therapy in adult subjects with plaque-type psoriasis since 1993. Calcipotriene foam, 0.005%, was approved in 2010 for the treatment of plaque psoriasis in adults aged 18 years and older. The current study is a multicenter study in which adolescent subjects (ages 12 to 16 years, inclusive) or their primary caregivers will apply calcipotriene foam, 0.005%, as a thin layer to treatment areas of the body and scalp, excluding the face, under maximal use conditions, twice a day for 14 days and once on Day 15. The safety, tolerability, pharmacodynamics, and pharmacokinetics of calcipotriene will be evaluated
