Investigator Global Assessment Scale (IGA) Score Change [ Time Frame: 8 Weeks ]
Achievement of an IGA score of 'clear' or 'almost clear' plus a 2-grade improvement from Baseline. This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2), Moderate (3), Severe (4).
Secondary Outcome Measures :
IGA Score Change [ Time Frame: Baseline, Week 2 and Week 4 ]
Achievement of an IGA score of 'clear' or 'almost clear' plus a 2-grade improvement from Baseline at weeks 2 and 4. This global assessment scale has five severity grades reported from 0-4 and defined as Clear (0), Almost Clear (1), Mild (2), Moderate (3), Severe (4).
Overall Assessment of Erythema Score [ Time Frame: Baseline, Week 2, Week 4, Week 8 ]
Change from Baseline in Overall Assessment of Erythema score at each study visit. Achievement of an Overall Assessment of Erythema score of 0 or 1 plus a 2-grade improvement from Baseline. This assessment scale has four severity grades reported from 0-3 and defined as None (0), Mild (1), Moderate (2), Severe (3).
Overall Assessment of Scaling Score [ Time Frame: Baseline, Week 2, Week 4, Week 8 ]
Change from Baseline in Overall Assessment of Scaling score at each study visit. Achievement of an Overall Assessment of Scaling score of 0 or 1 plus a 2-grade improvement from Baseline. This assessment scale has four severity grades reported from 0-3 and defined as None (0), Mild (1), Moderate (2), Severe (3).
Change in WI-NRS pruritus score from Baseline. In subjects with a Baseline WI-NRS pruritis score of > 4, achievement of a > 4-point improvement from Baseline. WI-NRS is a subject-reported severity of itch at its highest intensity during the previous 24-hour period. The scale is from '0 to 10' ("no itch" to "worst imaginable itch")

Females who are pregnant, wishing to become pregnant during the study, or are breast-feeding.
A clinically relevant history of abuse of alcohol or other drugs, at the discretion of the Investigator.
Subjects who are unable to communicate, read or understand the local language, or who display another condition, which in the Investigator's opinion, makes them unsuitable for clinical study participation.
