The UK-PBC Risk Score at endpoint is defined by the mean percentage risk that a PBC patient treated with ursodeoxycholic acid (UDCA) would develop liver failure requiring liver transplantation in 5, 10 and 15 years from diagnosis. The higher the score might indicate higher risk to death or live transplantation. Formula used for UK-PBC risk score = 1- 0.982 ^EXP(0.0287854*(ALP12 x ULN-1.722136304) - 0.0422873*(((TA12 xULN/10)^-1) - 8.675729006) + 1.4199 * (LN(BIL12 x ULN/10)+2.709607778)-1.960303*(Albumin x LLN-1.17673001)-0.4161954*(Platelet x LLN-1.873564875)). Where, Baseline survivor function = 0.982, 0.941, and 0.893 for 5 years, 10 years and 15 years respectively. ALP12, TA12 and BIL12 refers to the ALP, transaminases (ALT, AST), and total bilirubin assessments, respectively. The modified Intent-to-Treat (mITT) analysis set included all randomized subjects with confirmed PBC who received at least one study drug dose and had at least one post baseline ALP evaluation on treatment.
Change From Baseline in Pruritus Visual Analog Score (VAS) at Week 12 and Week 52
VAS is the commonly used graphic tool for self-reporting of pruritus intensity in patients. VAS is a simple to use, validated, reliable and widely applicable tool that does not determine the impact of pruritus to quality of life. It comprises of a 100-mm horizontal line labelled as "no symptom" on left end and "worst imaginable symptom" on right end. Based on the intensity of the itch patient is instructed to draw a vertical line on the horizontal scale having a range [VAS values (unit: mm) ranging from 0 to 100, where 0 represents "no itching" and 100 "worst possible itching"]. The modified Intent-to-Treat (mITT) analysis set included all randomized subjects with confirmed PBC who received at least one study drug dose and had at least one post baseline ALP evaluation on treatment.
Change From Baseline in PBC-40 Quality of Life (QoL) at Week 12 and Week 52
The PBC-40 QoL questionnaire is a disease-specific health-related tool developed for measuring the psychometric profile in PBC patients. It has 10 domains and 43 questions relevant to PBC, including Cognitive, Social, Emotional Function, Fatigue, Itch, and Other Symptoms. Questions in domains: 1) digestion and diet (questions 1-3); 2) experiences (questions 4-7); 3) itching (questions 8-10); 4) fatigue (questions 11-18); 5) effort and planning (questions 19-21); 6) memory and concentration (questions 22-27); 7) affects to you as person (questions 28-33); 8) affects to your social life (questions 34-37); 9) overall impact on your life (questions 38-40); 10) general health and well-being (questions A-C). Within a domain, items are scored from 1 to 5 and the individual item scores are summed to give a total domain score. High scores represent high impact and low scores low impact of PBC on QoL (mITT Population).
Percentage of Participants Meet Published PBC Response Criteria - Barcelona
Percentage of participants with response based on Barcelona risk scores was defined as Normalization of ALP or a Decrease of ALP ≥ 40%. The mITT analysis set included all randomized subjects with confirmed PBC who received at least one study drug dose and had at least one post baseline ALP evaluation on treatment.
Absolute Change in MELD Score From Baseline to 12 Weeks and 52 Weeks
Change from baseline to 12 weeks and 52 weeks in Model for End-stage Liver Disease (MELD) Score (mITT Population) The MELD score ranges from 6 to 40 and is a measure of how severe a patient's liver disease is. The higher the score, the more likely the patients will need a liver transplant. A calculated prognostic risk factor used to assess the potential need for a liver transplant. MELD(i) score = 10*[0.957*ln(creatinine mg/dL) + 0. 378*ln(total bilirubin mg/dL) + 1.120*ln (INR) + 0.643]. If MELD(i) is less than or equal to 11 then MELD = MELD(i). If MELD(i) is greater than 11 then MELD = MELD(i) + (1.32 *(137 - (Na)) - (0.033*MELD(i)*(137 - Na))
Change in GLOBE PBC Score From Baseline to 12 Weeks and 52 Weeks
Change from Baseline to 12 weeks and 52 weeks in Global PBC Study Group (GLOBE) score (mITT Population) The GLOBE score is a validated risk assessment tool providing an estimate of transplant-free survival for patients with PBC. It was developed by the Global PBC Study Group using Cox regression model on over 4,000 patients with PBC. Lower GLOBE score predicts lower risk. It is calculated from the following equation: GLOBE score = (0.044378 * age + 0.93982 * LN(total bilirubin/ULN) +(0.335648 * LN(alkaline phosphatase/ULN)) - 2.266708 * albumin /LLN -0.002581 * platelet count per 109/L) + 1.216865
Participants Meet Rotterdam Criteria
participants with Response Based on Rotterdam Criteria at Weeks 12 and 52 Rotterdam Published PBC Response Criteria by Visit (mITT Population) Rotterdam criteria: Early (normal total bilirubin and normal albumin), Moderately advanced (either abnormal albumin or abnormal total bilirubin), and Advanced (both abnormal albumin and abnormal total bilirubin). From Early stage to Moderate Stage and to Advanced Stage, it becomes worse and worse in abnormality.
Percentage of Participants Meet Composite Endpoint of AP and Total Bilirubin Criteria at Week 12 and Week 52
Percentage of participants with Response Defined by Composite Endpoint (ALP< 1.67 * Upper Limit of Normal [ULN] at Endpoint, Total Bilirubin [BIL] within Normal Limits at Endpoint, and Greater Than Equal To [≥] 15% ALP Reduction) from Baseline to Week 12 and Week 52 The mITT analysis set included all randomized subjects with confirmed PBC who received at least one study drug dose and had at least one post baseline ALP evaluation on treatment.
