Outcomes
Primary Outcomes
Percent Change From Baseline in Weekly Mean of the Daily 24-hour Worst Itch-Numeric Rating Scale (WI-NRS) Score at Week 4.
Time Frame: Baseline, Week 4 (28 days).
The WI-NRS is a tool used to assess the intensity of the most severe (worst) pruritus (itch), as experienced by the subject, in the last 24 hours. WI-NRS scale score ranges from 0 to 10, with 0 indicating no itch and 10 indicating the worst itch imaginable.
