Study Endpoints
Primary Endpoints
Percentage of Participants With Greater Than or Equal to (>=) 4 Points Improvement (Reduction) From Baseline in Worst-Itch Numeric Rating Scale (WI-NRS) Scores at Week 12
Baseline, Week 12

WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch). Higher scores indicated more severity. Percentage of participants with \>=4 points improvement (reduction) from baseline in WI-NRS scores at Week 12 is reported in this outcome measure.
