Study Endpoints
Primary Endpoints
Part A: Mean Change From Baseline in Monthly Itch Scores Over 24 Weeks Using Numerical Rating Scale (NRS)
Baseline and up to Week 24

Itch Scores were assessed using a NRS twice daily, ranging from 0 to 10, where 0 represents no itching and 10 the worst imaginable itching. The worst daily itch score was defined as the worst of the two scores recorded daily. The weekly itch score was defined as the average of the worst daily itch scores in one week. The monthly itch score was defined as the worst weekly itch score for the month (4 weeks). Higher monthly itch scores indicate worse itching. Baseline is the worst weekly itch score in the 28 days prior to randomization (Day 1). Change from Baseline is defined as the post dose value minus baseline value. Least-squares (LS) means and the corresponding 95% confidence intervals are reported by taking average of LS means of change from baseline in monthly itch scores obtained over 24 weeks using equal weighting for all time points. Analyzed using Mixed Model Repeated Measures (MMRM) method.
