During the study, WI-NRS assessments were reported by the participant via eDiary once daily from screening/mid-screening visit through the follow-up visit. The Itch NRS is a validated, self reported, instrument for measurement of itch intensity and participants were asked to rate the intensity of their itch on an 11- point scale ranging from 0 (no itch) to 10 (worst itch imaginable); higher scores indicated greater itch intensity. A participant was a 4-point responder if their change from baseline is ≤ -4 (i.e. a decrease of at least 4).
During the study, Worst Itch Numeric Rating Scale (WI-NRS) assessments were reported by the subject via eDiary once daily from screening/mid-screening visit through the follow-up visit. The Itch NRS is a validated, self-reported, instrument for measurement of itch intensity and subjects were asked to rate the intensity of their itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable); higher scores indicated greater itch intensity. Subjects were considered responders if they had at least a 4-point reduction from baseline in weekly average WI-NRS at Week 10.
During the study, Worst Itch Numeric Rating Scale (WI-NRS) assessments was reported by the subject via eDiary. The daily NRS results were summarized. The daily results were averaged to create weekly measures. The Itch NRS is a validated, self-reported, instrument for measurement of itch intensity. It used a 24-hour recall period and asked subjects to rate the intensity of their itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable), higher scores indicated greater itch intensity. A subject was a 4-point responder if their change from baseline is ≤ -4 (i.e. a decrease of at least 4).

It used a 24-hour recall period and asked subjects to rate the intensity of their itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable), higher scores indicated greater itch intensity. A subject was a 3-point responder if their change from baseline is ≤ -3 (i.e. a decrease of at least 3). Results presented below is of subjects who were a 3-point responder but not a 4-point responder.

The Itch Visual Analog Scale (VAS) is a validated, self-reported instrument for measurement of itch intensity. It used a 24-hour recall period and asked subjects to rate the worst intensity of their itch on a 100-mm horizontal line ranging from 0 mm (no itch) to 100 mm (worst itch imaginable). Higher scores indicated greater itch intensity. The VAS measurement were summarized in centimeters. WI-VAS assessments were reported by the subject via a paper form administered at study visits.
Worst Itch Numeric Rating Scale (WI-NRS). 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable). Higher scores indicate greater itch intensity. A 4-point responder is a subject who had at least a 4-point reduction in score between Baseline and Week 8.
Worst Itch Numeric Rating Scale (WI-NRS). 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable). Higher scores indicate greater itch intensity. The primary outcome is the change in WI-NRS score between the visit and Baseline.
