Participants were required to score the severity of their itching using a 0-10 numerical rating scale (NRS) where 0 represents no itching and 10 indicates the worst imaginable itching. The Worst Daily Itch Score is the most severe (highest) NRS recorded on a given day. Mean Worst Daily Itch score was calculated as the average of the worst daily itch scores provided in the 7 days prior to the Week 16 visit. Baseline is the average of the scores in the 7 days prior to the Week 4 (Visit 3 \[V3\]). Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Analysis was done using Analysis of covariance (ANCOVA) including treatment group and centered Mean Worst Daily Itch score at Baseline.

The change from Baseline was calculated by subtracting the Baseline values from the individual post-Baseline values. Baseline was defined as pre-dose Day -1 value. It was assessed on Baseline, Day 7 and 14. Data for fasting and weighted mean (WM) AUC(0-24 hour) glucose is provided. Statistics for least square mean is provided and participants withdrawing early were excluded. Results were based on an analysis of covariance (ANCOVA) model: change from Baseline = Baseline + treatment.
