Primary: Mean change from Baseline at Week 16 in the Mean Worst Daily Itch Score

End point title

Mean change from Baseline at Week 16 in the Mean Worst Daily Itch Score

End point description

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. Intent-to-Treat (ITT) Population comprised of all randomized participants who received at least one dose of study treatment, had a Baseline and at least one on-treatment assessment. Only those participants with data available at the specified data points were analyzed.

End point title

Mean change from Baseline at Week 16 in Primary Biliary Cholangitis-40 (PBC-40) scale

End point description

PBC-40 questionnaire consists of 40 questions arranged in 6 domains with 3 to 11 questions in each domain. Each question is scored from 1 (least impact) to 5 (greatest impact). All questions within a domain are summed to obtain individual domain score. Domains were: Symptoms (7 questions) with score range 7-35, Itch (3 questions) with score range 3-15, Fatigue (11 questions) with score range 11-55, Cognitive (6 questions) with score range 6-30, Emotional (3 questions) with score range 3-15, and Social (10 questions) with score range 10-50. Higher scores for individual domains represent a poor quality of life. Baseline is the assessment performed at Week 4 (V3) which is conducted prior to first dosing of randomized medication that evening. Change from Baseline was calculated as post-Baseline value minus Baseline value. Analysis was performed using ANCOVA including treatment group and Baseline. Only those participants with data available at the specified data points were analyzed.

Mean change from Baseline at Week 16 in serum alkaline phosphatase (ALP) concentrations, in participants with high risk of PBC progression

End point description

Criteria for high risk of PBC progression is defined as serum ALP concentrations more than or equal to (>=)1.67 times upper limit of normal (ULN) range and/or total bilirubin concentrations more than (>)ULN at Day 1. Baseline is the assessment performed at Week 4 (V3), or if missing then Visit 2 (Day 1) or Visit 1 (Screening), excluding unscheduled visits. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Analysis was performed using ANCOVA including treatment group and Baseline. High Risk Population comprised of subset of the ITT population who were assigned to the High Risk stratum for randomization (based upon serum ALP concentrations >=1.67 times ULN and/or total bilirubin concentrations >ULN at Day 1 (Visit 2). Only those participants with data available at the specified data points were analyzed.

Number of participants with clinical chemistry data of potential clinical importance

End point description

Blood samples were collected to measure analyze the following parameters: albumin, calcium, Glomerular filtration rate (GFR) from creatinine, glucose, potassium and sodium. Participants were counted in the worst case category that their value changes to (low, within range [w/in] or no change, or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (for example [e.g.], high to high), or whose value became within range, were recorded in the "To w/in Range or No Change" category. Participants were counted twice if the participant had values that changed "To Low" and "To High", so the percentages may not add to 100 percent (%). Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles). Only “To Low” and/or “To High” categories with potential clinical importance data have been presented.

Number of participants with hematology data of potential clinical importance

End point description

Blood samples were collected to analyze the following parameters: hematocrit, hemoglobin, leukocytes, lymphocytes, neutrophils and platelets. Participants were counted in the worst case category that their value changes to (low, w/in or no change, or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., high to high), or whose value became within range, were recorded in the "To w/in Range or No Change" category. Participants were counted twice if the participant had values that changed "To Low" and "To High", so the percentages may not add to 100%. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles). Only “To Low” and/or “To High” categories with potential clinical importance data have been presented.

Number of participants with abnormal 12-Lead Electrocardiogram (ECG) parameters

End point description

A 12-lead ECG was recorded with the participant in a semi-supine position. 12-lead ECGs were obtained by using an automated ECG machine. Data for abnormal, not clinically significant (NCS) and clinically significant (CS) ECG findings are presented. CS abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

Change from Baseline in Gastrointestinal Symptom Rating Scale (GSRS) assessment

End point description

GSRS was measured for all 5 domains: Average Diarrhea Syndrome Score, Average Indigestion Syndrome Score, Average Constipation Syndrome Score, Average Abdominal Pain Syndrome Score, Average Reflux Syndrome Score. All individual domains are scored on a 7-point Likert scale ranging from 1(not at all) to 7(extremely). Higher score indicate more severe symptoms. The Average Total GSRS score was mean of these 5 domains and ranges from 1 to 7. Higher score indicates worst possible degree of symptoms. The responses summarized at each visit are those given during the week prior to the visit, with exception of Day 1. Baseline is the most recent assessment completed by participant prior to randomization. Change from Baseline was calculated as post-Baseline value minus the Baseline value. Data has been presented for each domain along with the average Total GSRS score. Only those participants with data available at the specified data points were analyzed.

Percentage of responder days with improvement of >= 30% in the Mean Worst Daily Itch Score at Week 16 from Baseline

End point description

Percentage of Responder Days with Worst Daily Itch score was calculated as: (number of days response from Visit 3+1 to Visit 6-1 divided by number of days from Visit 3+1 to Visit 6-1 with worst daily itch scores available) times 100. Days for which no worst daily itch score was available did not contribute to either the numerator or the denominator. Analysis was performed using ANCOVA model including treatment group. Baseline is the most recent assessment completed by the participant prior to randomization. Percentage of responder days with improvement of >= 30% in the Mean Worst Daily Itch Score at Week 16 from Baseline is presented.

Change from Baseline in the Five Dimensional (5-D) Itch Scale at Week 16

End point description

The 5-D itch scale is instrument for multidimensional quantification of itch that is sensitive to change over time. It has data to support its validity in pruritus participants and covers five dimensions of itch: duration, degree, direction, disability and distribution. Each domain was scored on a 5-point scale, ranging from 1 (Not present/resolved/never) to 5 (unbearable/getting worse/always), higher scores indicates worst itching. The scores of each of five domains were achieved separately and then summed together to obtain a total 5-D score. A total 5-D scores ranged between 5 (no pruritus) and 25 (most severe pruritus) where higher score indicates worse possible itching. Baseline is assessment performed at Week 4 (V3) which is conducted prior to first dosing of randomized medication that evening. Change from Baseline was calculated as post-Baseline value minus Baseline value. Only those participants with data available at the specified data points were analyzed

End point title

Mean change from Baseline in Monthly Itch Score

End point description

Participants were required to score severity of their itching each morning and evening using a 0-10 NRS where 0(no itching) and 10(worst imaginable itching). The worst of these 2 scores was Worst Daily Itch Score. For each week, mean Worst Daily Itch Score was calculated to form Mean Worst Daily Itch Score. The Monthly Itch Score was defined as worst weekly score (e.g., Mean Worst Daily Itch Score) for that month. The monthly itch score ranges from 0 to 10, higher score indicates worst imaginable itching. Baseline is average of scores in the 7 days prior to Week 4 (Visit 3 [V3]). Change from Baseline was calculated as post-Baseline value minus Baseline value. Analysis was performed on change in Monthly Itch Scores over 12 week treatment period using Mixed model repeated measures (MMRM) with Baseline itch, treatment group, visit and a treatment group*visit interaction as covariates in the model. Only those participants with data available at the specified data points were analyzed.

Ratio to Baseline in Total Serum Bile Acid Concentration

End point description

Baseline is the assessment performed at Week 4 (V3), or if missing then Visit 2 (Day 1) or Visit 1 (Screening), excluding unscheduled visits. Ratio to Baseline was defined as the geometric mean of post-Baseline visit value divided by the geometric mean of Baseline value. Values were log-transformed and mean change from Baseline on the log-scale was calculated over the 12 week treatment period. Analysis was performed on change in total serum bile acid concentration on the log-scale over the 12 week treatment period using MMRM with log-transformed Baseline total serum bile acid, visit, treatment group, a log-transformed Baseline total serum bile acid*visit interaction, and a treatment group*visit interaction used as covariates in the model. Afterwards, values were back-transformed to the original scale. Ratios of geometric means are presented. Only those participants with data available at the specified data points were analyzed.
