PK and PD Study of Calcitriol 3 mcg/g Ointment in Pediatric Subjects With Plaque Psoriasis

Pharmacokinetics and Pharmacodynamics of Calcitriol 3 mcg/g Ointment Applied Twice Daily for 14 Days Under Conditions of Maximal Use in Pediatric Subjects (2 to 12 Years of Age) With Plaque Psoriasis

The purpose of this study is to determine if the calcitriol absorption in pediatric subjects is comparable to that in adults and adolescents, with no significant impact on calcium/phosphorus metabolism.
