32 subjects were randomly allocated to 4 treatment groups (8 subjects per dose). In a single administration period, subjects were treated with assigned 0.3 % OPA-15406 ointment assessed until 48 hours postdose. In the multiple administration period, same subjects were treated with assigned 0.3% OPA-15406 ointment twice daily for 14 days and assessed until 48 hours post dose.

Cmax of OPA-15406 in a Single Administration Period
We measure the plasma concentration of OPA-15406 at Day 1 by applying 0.3%, 1%, or 3% formulation of OPA-15406 ointment as a single dose. We assess the Cmax of OPA-15406.
Time frame: Baseline, 2 ,3, 4, 8, 10, 12, 16, 24 and 48 hr
Cmax of OPA-15406 in the Multiple Administration Period
We measure the plasma concentration of OPA-15406 from Day 1 to Day 14 by applying 0.3%, 1%, or 3% formulation of OPA-15406 ointment as multiple doses twice daily for 2 weeks. We assess the AUC12h x of OPA-15406.
Time frame: Baseline, 2 ,3, 4, 8, 10, 12, 16, 24 and 48 hrs at Day 14
