Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy Endpoints-1-point IGA	Proportion of subjects with 1-point reduction on the Investigator's Global Assessment (IGA) from Baseline. The IGA assesses overall severity of a subject's NS based on a 5-point scale where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe.	Up to week 16
Primary	Efficacy Endpoints-2-point IGA	Proportion of subjects with 2-point reduction in IGA from Baseline.	Up to week 16
Primary	Efficacy Endpoints-NS Sign	Change from Baseline in each individual NS Sign (erythema and scaling). Severity of each NS sign is graded on a 5-point scale.	Up to week 16
Primary	Efficacy Endpoints-BSA	Change from Baseline in total Body Surface Area (BSA) affected by NS in the Treatment Area	Up to week 16
Primary	Efficacy Endpoints-WI-NRS score	Change from Baseline in the Worst Itch-Numeric Rating Scale (WI-NRS) score. Itch severity is graded on an 11-point scale where 0 represents "no itch" and 10 represents "worst itch imaginable".	Up to week 16
Primary	Efficacy Endpoints-TSQM	Assessment of subject satisfaction with treatment based on the Treatment Satisfaction Questionnaire for Medication (TSQM). The TSQM measures a subject's level of satisfaction or dissatisfaction with the treatment. Composite scores can range from 0 to 100; higher scores indicate better satisfaction.	Up to week 16
