Summary:

      This will be a single-center, randomized, double-blinded, vehicle-controlled clinical study
      to determine the efficacy of Enstilar® foam, a combination of calcipotriene and betamethasone
      dipropionate 0.005%/0.064%, in the treatment of psoriasis vulgaris in skin of color (FST
      IV-VI). This study will also evaluate the degree of erythema versus hyperpigmentation in
      psoriasis plaques in skin of color (and its change with Enstilar ® treatment) as well as the
      effect of Enstilar ® on post-inflammatory hyperpigmentation and quality of life.
