What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Worst-itching 11-point Numerical Rating Scale (NRS)
The subject indicated the number on the line from left (0:no itching) to right (10:worst itch I have ever experienced). Assessments was made twice daily using an electronic Patient Reported Outcomes (ePRO) device from the Screening Visit to the Follow-up Visit (Week 9). The 2 daily assessments was separated by 12 h, at approximately 8 am and at approximately 8 pm. Subjects selected the number that best described the worst itch during the day (assessed at approximately 8 pm) or during the night (assessed at approximately 8 am). The day or night score, whichever was greater, was used to calculate the weekly average score and changes from baseline (average over the Run-in Phase [Days -7 to -1]) score in weekly average at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 week
Change From Baseline in Worst-itching Visual Analog Scale (VAS)
The subject placed a single vertical mark on the line of a VAS corresponding to degree of itching intensity from left (no itching) to right (worst itch I have ever experienced). The VAS represents a 100 mm line. It consists of 101 selectable regions and the subject's score on the VAS will correspond to the region (0 to 100) selected on the line. Assessments was made twice daily using an ePRO device from the Screening Visit to the Follow-up Visit (Week 9). The 2 daily assessments was separated by 12 h, in the morning at approximately 8 am and in the night at approximately 8 pm. Subjects put a single vertical mark on the line to show the intensity of your worst itching during the day or during the night. The day or night score, whichever was greater, was used to calculate the weekly average score and changes from baseline in weekly average at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 weeks
Change From Baseline in Itch Severity Score
The subject performed an assessment on day and nighttime symptoms of itch and effect of itch on sleep using a 5-point ordinal scale of itchiness (0 = none, 1 = mild, 2 = Moderate, 3=Severe, 4 = very severe). Assessments was made during each dialysis treatment (3x/week) and recorded on paper from the Screening Visit to the Follow-up Visit (Week 9). Change from Baseline (average over the Run-in Phase [Days -7 to -1]) in Weekly Averages of Itch Severity Score were assessed and score at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 weeks
Change From Baseline in Sleep Quality Assessment
The PSQI has a minimum possible score of 0 (better sleep quality) and a maximum possible score of 10 (worse sleep quality). Subjects was asked to rate their sleep experience during the previous week. Pittsburgh Sleep Quality Index (PSQI) modified assessment was made during the dialysis treatment 1x/week every week and recorded on paper from the Screening Visit to the Follow-up Visit (Week 9).Change from Baseline (the Run-in Phase [Days -7 to -1]) were assessed and score at 2, 4 and 8 weeks as specified in the protocol are reported. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 weeks
Change From Baseline in QoL Assessment (Skindex-10)
The Skindex-10 has a minimum possible score of 0 (itching not bothersome) and a maximum possible score of 60 (itching very bothersome). The Skindex-10 is a self-administered questionnaire used to evaluate the health-related QoL in UP. It is comprised of 10 questions, adopted for pruritus from the Skindex-16, a widely used instrument for a variety of skin disease. Subjects was asked to identify on paper at Baseline and Weeks 2, 4, and 8 (EOT) what has bothered them most during the past week by marking along a scale 0 to 6 boxes from "never bothered" to "always bothered. Change from Baseline (the Run-in Phase [Days -7 to -1]) were assessed. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 weeks
The Mean Value in Treatment Satisfaction (Patient's Global Impression of Change )
The PGIC has a minimum possible score of 1 (very much improved) and a maximum possible score of 7 (very much worse). Subjects was asked to use a categorical scale with 7 categories to describe their global impression of change (PGIC) with study drug treatment. Subjects recorded their impression of change on paper at Weeks 2, 4, and 8 (EOT).
Although the change from baseline (run-in phase [Days -7 to -1]) was specified as an outcome in this study, it was not calculated because the target enrollment was not met and no meaningful statistical analysis could be expected. Therefore, the mean value of patients at each point is shown instead.
Measured: 2 weeks, 4 weeks and 8 weeks
Change From Baseline in QoL Assessment (5-D-Itch Scale)
The 5-D-Itch scale has a minimum possible score of 5 (better) and a maximum possible score of 25 (worse). Subjects was asked to assess QoL by means of the 5D-Itch-Scale at Baseline, Weeks 2, 4, and 8 (EOT). The 5D-Itch Scale is a 5-item (duration, degree, direction, disability, and distribution) multidimensional measure of pruritus itch. Change from Baseline (the Run-in Phase [Days -7 to -1]) were assessed. Amount of change score of plus indicates worsening, and minus indicates improvement.
Measured: 2 weeks, 4 weeks and 8 weeks
The Number of Patients in Excoriation
Investigator and/or the designated medically qualified staff assessed the subject's excoriation at Baseline, and weekly thereafter, by completing the subject's answers to the following questions:
Excoriation present? Yes/No If yes, please rate the severity: Mild/Moderate/Severe
Although the change from baseline (run-in phase [Days -7 to -1]) was specified as an outcome in this study, it was not calculated because the target enrollment was not met and no meaningful statistical analysis could be expected. Therefore, the number of patients at each point is shown instead.
Measured: 2 weeks, 4 weeks and 8 weeks
