| Primary | Percentage of Participants With Improvement (Reduction) in Worst Itch Numeric Rating Scale (WI-NRS) Scores by Greater Than or Equal to (>=) 4 Points From Baseline to Week 24 | Baseline, Week 24 | 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 improvement (reduction) in WI-NRS scores by \>=4 points from Baseline to Week 24 is reported in this outcome measure. |

In this outcome measure, percentage of participants with IGA PN-S score of either 0 (clear) or 1 (almost clear) has been reported. |
