What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Pruritus Using Adult Itch Reported Outcome (ItchRO) Weekly Sum Score at Week 13/ Early Termination (ET)
Pruritus was assessed using ItchRO measure, administered as an electronic diary (eDiary) which was completed by the participants twice daily (morning and evening). (ItchRO) scores ranged from 0 to 10, with 0 representing no itch and 10 representing very severe itching. The highest score between the morning and evening ItchRO reports represented the daily score: a measure of the worst itching over the previous 24-hour period. The weekly sum score was calculated as the sum of the daily scores for the 7 days prior to the time point being reported: 7 days prior to randomization or 7 days prior to Week 13/ET visit.
Measured: Baseline and Week 13/ET
Secondary outcomes (6)
Change From Baseline in Pruritus Using Adult ItchRO Weekly Sum Scores at Weeks 4, 8 and 13
ItchRO scores had a range from 0 to 10, with 0 representing no itch and 10 representing very severe itching. The highest score between the morning and evening ItchRO reports represented the daily score: a measure of the worst itching over the previous 24-hour period. The weekly sum score was calculated as the sum of the daily scores for the 7 days prior to the time point being reported: 7 days prior to randomization or 7 days prior to Week 13/ET visit.
Measured: Baseline, Weeks 4, 8 and 13
Change From Baseline in Pruritus Using Adult ItchRO Average Daily Scores at Weeks 4, 8, 13, and Last Post-baseline Visit (Week 13/ET)
ItchRO scores had a range from 0 to 10, with 0 representing no itch and 10 representing very severe itching. The highest score between the morning and evening ItchRO reports represented the daily score: a measure of the worst itching over the previous 24-hour period. Adult ItchRO average daily score was the sum of daily scores divided by the number of days adult ItchRO was completed, using the 7 days prior to the reported visit date.
Measured: Baseline, Weeks 4, 8, 13 and Last Post-baseline visit (Week 13/ET)
Change From Baseline in Alkaline Phosphatase (ALP) at Weeks 4, 8, 13, and Last Post-baseline Visit (Week 13/ET)
Laboratory serum ALP enzyme levels were evaluated using blood samples collected.
Measured: Baseline, Weeks 4, 8, 13 and Last Post-baseline (Week 13/ET)
Change From Baseline in 5-D Itch Score at Weeks 4, 8, 13, and Last Post -Baseline Visit (Week 13/ET)
The 5-D itch (validated instrument to measure pruritus) scale was developed for the multidimensional quantification of pruritus that is sensitive to change over time. The 5-D itch scale included 5 domains (duration, degree, direction, disability, and distribution of pruritus). The total 5-D score was obtained by scoring each of the domains separately and then summing them together. 5-D total scores ranged between 5 (no pruritus) and 25 (most severe pruritus).
Measured: Baseline, Weeks 4, 8, 13 and Last Post-baseline visit (Week 13/ET)
Change From Baseline in Fasting Serum Bile Acid Level at Weeks 4, 8, 13, and Last Post -Baseline Visit (Week 13/ET)
Laboratory serum bile acid level levels were evaluated using blood samples collected.
Measured: Baseline, Weeks 4, 8, 13 and Last Post-baseline visit (Week 13/ET)
Change From Baseline in Bile Acid Synthesis as Measured by Serum 7 Alpha-Hydroxy-4-Cholesten-3-One C4 Level [7 Alpha C4]) at Weeks 4, 8, 13, and Last Post -Baseline Visit (Week 13/ET)
C4 7 alpha-hydroxy-4-cholesten-3-one is an intermediate in the biochemical synthesis of bile acids from cholesterol and its concentrations reflect the activity of the bile acid synthetic pathway. Elevated levels of C4 indicate bile acid malabsorption. Laboratory C4 levels were evaluated using blood samples collected.
Measured: Baseline, Weeks 4, 8, 13 and Last Post-baseline Visit (Week 13/ET)

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
