J-LINX: Japan LINerixibat eXtension Study

• Participants with a diagnosis of PBC and a history of associated pruritus as evidenced by randomization into an eligible linerixibat clinical study prior to LLSAT (GLIMMER or GLISTEN)
• Participants must have completed the main treatment period in LLSAT

• A Female participant is eligible to participate if she is not pregnant or breastfeeding and one of the following applies:

  • Is a woman of non-childbearing potential (WONCBP), OR
  • Is a woman of childbearing potential (WOCBP) and using an acceptable contraceptive method during the study intervention period (at a minimum until 4 weeks after the last dose of study intervention). The investigator should evaluate the potential for contraceptive method failure (e.g., noncompliance, recently initiated in relationship to the first dose of study intervention, etc.)

• WOCBP must have a negative highly sensitive urine pregnancy test (or serum, as required by local regulations) within 7 days before the baseline visit

  • If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive
• Capable of giving signed informed consent

Exclusion Criteria:

• Participants who met LLSAT protocol-defined Liver Monitoring or Liver Stopping criteria and who remain off study treatment or where Liver Event is not resolved at the Final Visit in LLSAT
• Presence of hepatic decompensation (e.g., current and unresolved variceal bleeding, encephalopathy, or ascites)
• Presence of confirmed hepatocellular carcinoma or biliary cancer
• Current clinically significant diarrhea in the investigator's medical opinion
• Any current medical condition (e.g., psychiatric disorder, senility, or dementia) which, in the investigator's opinion, may affect the participant's ability to comply with protocol-specified procedures
• Current enrollment or participation in any other clinical study (except for LLSAT) involving an investigational study treatment within 8 weeks prior to the Screening Visit
• Corrected QT Interval (QTc) >480 milliseconds (msec) at screening (12-lead Electrocardiogram [ECG]), subject to rescreening
