Brief summary
An 8-week, dose ranging, open label, randomized, Phase 2 study with a 44-week extension, to evaluate the safety and efficacy of MBX-8025 in subjects with Primary Biliary Cholangitis (PBC) and an inadequate response to or intolerance to ursodeoxycholic acid (UDCA)
Detailed description
Primary: To evaluate the safety and efficacy of MBX-8025 2 mg, 5 mg, and 10 mg over 8 weeks of treatment Secondary: To evaluate the safety and efficacy of MBX-8025 2 mg, 5 mg, and 10 mg over 12 and 26 weeks of treatment To evaluate the safety and efficacy of MBX-8025 2 mg, 5 mg, and 10 mg over 52 weeks of treatment To evaluate the pharmacokinetics (PK) of MBX-8025 Exploratory: To evaluate the effect of MBX-8025 on bile acids, additional markers of inflammation and renal function MBX-8025 doses of 1 mg and 15 mg may be evaluated if dose adjustment occurs
Interventions
Initial 8-week treatment: • MBX-8025 2 mg Extension: The 2 mg group will be started after safety and efficacy review of the 5 mg and the 10 mg groups has been completed. Subjects will initially enter the extension on their assigned dose. The dose might be up- or down-titrated after safety and efficacy data review of the first 8 weeks of treatment. During the extension, a subject's dose might be re-adjusted for safety or efficacy reasons.
Initial 8-week treatment: • MBX-8025 5 mg Extension: Subjects will initially enter the extension on their assigned dose. The dose might be up- or down-titrated after safety and efficacy data review of the first 8 weeks of treatment. During the extension, a subject's dose might be re-adjusted for safety or efficacy reasons.
Initial 8-week treatment: • MBX-8025 10 mg Extension: Subjects will initially enter the extension on their assigned dose. The dose might be up- or down-titrated after safety and efficacy data review of the first 8 weeks of treatment. During the extension, a subject's dose might be re-adjusted for safety or efficacy reasons.

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 |

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.
Time frame: 12 weeks and 52 weeks
Population: mITT Population. The mITT population is defined as any enrolled subject who receives at least one dose of medication and has at least one post-baseline AP evaluation and who have confirmed PBC.

Population: mITT Population. The mITT population is defined as any enrolled subject who receives at least one dose of medication and has at least one post-baseline AP evaluation and who have confirmed PBC.

UK-PBC Risk Score Value
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.
Time frame: 12 weeks and 52 weeks
Population: mITT Population. The mITT population is defined as any enrolled subject who receives at least one dose of medication and has at least one post-baseline AP evaluation and who have confirmed PBC.
