Primary Outcome Measures
NameTimeMethod
Change from baseline in mean itch Numerical Rating Scale (NRS) score at week 4Up to 58 weeks

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.

Secondary Outcome Measures
NameTimeMethod
Change from baseline in 5-D itch scale scoreWeek 4, 10, 18, 26, 34, 46, 58

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.

Change from baseline in mean itch scores based on the Shiratori severity criteriaUp to 58 weeks

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.

Percentage of subjects with 4-point improvement in mean itch NRS scoreUp to 58 weeks

Percentage of subjects with 4-point improvement whose change from baseline in mean itch NRS score is ≤ -4

Percentage of subjects with global symptoms in Patient Global Impression of Change (PGIC)Week 4, 10, 18, 26, 34, 46, 58

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.

Change from baseline in mean itch NRS scoreUp to 58 weeks

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.

Percentage of subjects with 3-point improvement in mean itch NRS scoreUp to 58 weeks

Percentage of subjects with 3-point improvement whose change from baseline in mean itch NRS score is ≤ -3

Change from baseline in Skindex-16 scoreWeek 4, 10, 18, 26, 34, 46, 58

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.
