Primary	Change From Baseline in the Weekly Mean of the Daily 24-hour WI-NRS Score at Week 4 of the DB Period	From Baseline to Week 4	On a daily basis, participants recorded the intensity of the worst itching they experienced over the past 24 hours using a numerical rating scale (NRS) scale from 0 to 10, where 0 represents "no itching" and 10 was "worst itching imaginable". A higher score indicated a more severe outcome. The weekly mean of the daily values of the daily 24-hour WI-NRS was calculated for the analysis. The least square (LS) means of change from baseline to Week 4 in the weekly mean of the daily 24-hour WI-NRS score was estimated using the mixed model repeated measures (MMRM) method. The MMRM model included use of prior anti-itch medication (yes/no), presence of specific medical conditions at baseline (yes/no), treatment, visit, and treatment-by-visit-interaction as fixed categorical effects and baseline WI-NRS score as fixed continuous effects.
Secondary	Percentage of Participants Achieving Greater Than or Equal to (>=) 3-point Improvement From Baseline With Respect to the Weekly Mean of the Daily 24-hour WI-NRS in the DB Period	From Baseline, and at Weeks 4, 8, and 12	On a daily basis, participants recorded the intensity of the worst itching they experienced over the past 24 hours using a NRS scale from 0 to 10, where 0 represents "no itching" and 10 was "worst itching imaginable". A higher score indicated a more severe outcome. The weekly mean of the daily values of the daily 24-hour WI-NRS was calculated for the analysis. Missing weekly mean WI-NRS data were imputed using missing at random (MAR) multiple imputation (MI) approach, assuming that participants who do not have weekly mean WI-NRS score at a timepoint would have similar weekly mean WI-NRS scores as other participants in their respective treatment arm who have complete data. The percentage of participants were estimated using a logistic regression model with terms for treatment group, baseline WI-NRS score, use of anti-itch medication during the week prior to randomisation, and the presence of specific medical conditions at baseline.
Secondary	Percentage of Participants Achieving at Least 4-point Improvement From Baseline With Respect to the Weekly Mean of the Daily 24-hour WI-NRS in the DB Period	From Baseline, and at Weeks 4, 8, and 12	On a daily basis, participants recorded the intensity of the worst itching they experienced over the past 24 hours using a NRS scale from 0 to 10, where 0 represents "no itching" and 10 was "worst itching imaginable". A higher score indicated a more severe outcome. The weekly mean of the daily values of the daily 24-hour WI-NRS was calculated for the analysis. Missing weekly mean WI-NRS data were imputed using MAR-MI approach, assuming that participants who do not have weekly mean WI-NRS score at a timepoint would have similar weekly mean WI-NRS scores as other participants in their respective treatment arm who have complete data.
Secondary	Change From Baseline in the Weekly Mean of the 24-hour WI-NRS Score at Each Week of the DB Period	From Baseline to Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12	On a daily basis, participants recorded the intensity of the worst itching they experienced over the past 24 hours using a NRS scale from 0 to 10, where 0 represents "no itching" and 10 was "worst itching imaginable". A higher score indicated a more severe outcome. The weekly mean of the daily values was calculated for the analysis. The weekly mean of the daily values of the daily 24-hour WI-NRS was calculated for the analysis. The MMRM model included use of prior anti-itch medication (yes/no), presence of specific medical conditions at baseline (yes/no), treatment, visit, and treatment-by-visit-interaction as fixed categorical effects and baseline WI-NRS score as fixed continuous effects.
Secondary	Change From Baseline in Itch-related Quality-of-life (QoL) as Assessed by the 5-D Itch Scale Total Score (DB Period)	From Baseline to Weeks 4, 8, and 12	The 5-D itch scale is a questionnaire where participants assess the 5 dimensions of itch (degree, duration, direction, disability, and distribution). The scores of each of the 5 domains are achieved separately and then summed together to obtain a total 5-D score. 5-D itch scale scores can potentially range between 5 (no pruritus) and 25 (most severe pruritus) where a higher score indicates a more severe outcome. The LS means of change from baseline in itch-related QoL as assessed by the 5-D itch scale total score was estimated using the MMRM method. The MMRM model included use of prior anti-itch medication (yes/no), presence of specific medical conditions at baseline (yes/no), treatment sequence, visit, and treatment sequence-by-visit-interaction as fixed categorical effects and baseline 5-D Itch score (total score) as fixed continuous effects.
Secondary	Change From Baseline in Itch-related QoL as Assessed by the 5-D Itch Scale Total Score (OLE Period)	From Baseline to OLE Period - Weeks 4, 8, 12, and 14	The 5-D itch scale is a questionnaire where participants assess the 5 dimensions of itch (degree, duration, direction, disability, and distribution). The scores of each of the 5 domains are achieved separately and then summed together to obtain a total 5-D score. 5-D itch scale scores can potentially range between 5 (no pruritus) and 25 (most severe pruritus) where a higher score indicates a more severe outcome. The LS means of change from baseline in itch-related QoL as assessed by the 5-D itch scale total score was estimated using the MMRM method. The MMRM model included use of prior anti-itch medication (yes/no), presence of specific medical conditions at baseline (yes/no), treatment sequence, visit, and treatment sequence-by-visit-interaction as fixed categorical effects and baseline 5-D Itch score (total score) as fixed continuous effects.
Secondary	Change From Baseline in Itch-related QoL as Assessed by the Skindex-10 Scale Total Score (DB Period)	From Baseline to Weeks 4, 8, and 12	The Skindex-10 scale is a questionnaire that measures QoL in relationship to the itch intensity. Participants are asked the question "During the past week, how often have you been bothered by" and respond by filling in 1 of 7 circles numbered from 0 (labelled with the anchor phrase "never bothered") to 6 (labelled as "always bothered") for each of the 10 questions. The total score is the sum of the numeric value of each answered question. Here, a higher score indicated a severe outcome. The LS means of change from baseline in itch-related QoL as assessed by the Skindex-10 scale total score was estimated using the MMRM method. The MMRM model included use of prior anti-itch medication (yes/no), presence of specific medical conditions at baseline (yes/no), treatment, visit, and treatment-by-visit-interaction as fixed categorical effects and baseline skindex-10 scale score (total score) as fixed continuous effects.

Secondary	Patient Global Impression of Change	At Week 12	The Patient Global Impression of Change is a global participant reported outcome measure that assesses the change in itch (no change, improvement or worsening) overall relative to the start of the study. The scale has only 1 item, and the participant was asked to mark the category that best describes the change in itch ranging from "Very Much Improved" to "Very Much Worse". Number of participants within all individual categories are reported here.
Secondary	Number of Participants With Adverse Events (AEs)	Up to Week 27 (12 weeks in DB + 14 weeks in OLE +1 week of follow up)
Secondary	Number of Participants With Clinically Significant Abnormal 12-lead Electrocardiogram (ECG)	Up to Week 27 (12 weeks in DB + 14 weeks in OLE +1 week of follow up)
Secondary	Number of Participants With Clinically Relevant Change From Baseline in Vital Signs and Laboratory Evaluations	From baseline to Week 27 (12 weeks in DB + 14 weeks in OLE +1 week of follow up)
