Primary outcomePrimary: Trough Plasma Levels (Ctrough) of Calcitriol — 65.04; 62.53; 61.87; 61.46 Picograms Per Millilitre (pg/mL)
Summary
This is an open-label, multicenter study to assess the systemic exposure to calcitriol in the adolescent population. Calcitriol 3µg/g ointment (2 mg/cm² per application) is to be applied twice daily to involved skin (10 - 35% BSA involved, excluding face, scalp and intertriginous areas) for 56 days (8 weeks). Full Pharmacokinetic (PK) and Pharmacodynamic (PD) profile will be collected during the first 3 weeks of the study; safety and efficacy data will be collected for the 8 weeks of the treatment.
