Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in mean itch Numerical Rating Scale (NRS) score at week 4	The most severe itching within the day will be recorded in integers on a scale ranging from 0 to 10, where 0 represents no itching and 10 represents worst itching imaginable.	Up to 58 weeks
Secondary	Change from baseline in mean itch NRS score	The most severe itching within the day will be recorded in integers on a scale ranging from 0 to 10, where 0 represents no itching and 10 represents worst itching imaginable.	Up to 58 weeks
Secondary	Change from baseline in mean itch scores based on the Shiratori severity criteria	The symptoms during the day and the night will be recorded on a scale ranging from 0 to 4, where 0 represents no symptoms and 4 represents severe itching.	Up to 58 weeks
Secondary	Percentage of subjects with 3-point improvement in mean itch NRS score	Percentage of subjects with 3-point improvement whose change from baseline in mean itch NRS score is = -3	Up to 58 weeks
Secondary	Percentage of subjects with 4-point improvement in mean itch NRS score	Percentage of subjects with 4-point improvement whose change from baseline in mean itch NRS score is = -4	Up to 58 weeks
Secondary	Change from baseline in Skindex-16 score	The frequency of bothered by itching will be recorded based on scale ranging from 0 to 6, where 0 represents never bothered and 6 represents always bothered.	Week 4, 10, 18, 26, 34, 46, 58
Secondary	Change from baseline in 5-D itch scale score	Five components of condition of itching (duration, degree, direction, disability, distribution) will be recorded based on scale ranging from 5 to 25, with higher scores indicating worse itch-related QOL.	Week 4, 10, 18, 26, 34, 46, 58
Secondary	Percentage of subjects with global symptoms in Patient Global Impression of Change (PGIC)	Subjects will record the overall symptom of itching from the screening period based on a 7-level scale consisting of very much improved, much improved, minimally improved, no change, minimally worsened, much worsened, and very much worsened.	Week 4, 10, 18, 26, 34, 46, 58
