入选标准

  • Participants are eligible to be included in the study only if all of the following criteria apply:
  • Sex and Age
  • 1. Male and female participants must be between 18 to 80 years of age inclusive, at the time of signing the informed consent.
  • Note: if country/site age requirements for consent differ, the more stringent (e.g., higher age) restriction will be required for that country/site.
  • Type of Participant and Disease Characteristics
  • 2. Participants who have proven PBC, as demonstrated by historically having at least 2 of the following:
  • Documented history of sustained increased ALP levels greater than ULN first recognized at least 6 months prior to the Screening Visit (Note: Sustained ALP elevations at the time of Screening is not required, recognizing that the ALP may have decreased after initiation of UDCA therapy).
  • Documented positive anti-mitochondrial antibody (AMA) titer (>1:40 titer on immunofluorescence or M2 positive by enzyme linked immunosorbent assay [ELISA]) or PBC-specific antinuclear antibodies (antinuclear dot and/or nuclear rim positive).
  • Liver biopsy (documented at any time in the past) consistent with PBC.
  • 3. Participants who, during the Screening period, record their daily itch score by entering at least 40 of the 56 required itch entries, with an entry on at least 4 days in each week, during the 4-week period immediately preceding Randomization at Day 1 and have a Monthly Itch Score of =4 (i.e., at least 1 of the 4 weekly Mean Worst Daily Itch Scores must be =4), and no Mean Worst Daily Itch Score can be <3 for any other week.
  • Contraceptive/Barrier Requirements
  • 4. Contraceptive/Barrier Requirements (applicable for female participants only): A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies:
  • o Is not a woman of non-childbearing potential
  • o Is a woman of childbearing potential (WOCBP) and using an acceptable contraceptive method as described in Section 10.4 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.
  • A WOCBP must have a negative highly sensitive urine pregnancy test (or serum as required by local regulations) within 7 days before the first dose of study intervention, see Section 8.2.5 Pregnancy Testing.
  • Additional requirements for pregnancy testing during and after study intervention are located in Section 8.2.5.
  • The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy
  • Note: Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
  • Full requirements for pregnancy testing during and after study intervention are located in Section 10.4 Appendix 4.
  • Informed Consent
  • 5. Capable of giving signed informed consent as described in Section 10.1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 175
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Numbe

排除标准

  • 1. Participants with symptoms suggestive of active COVID-19 infection (i.e. fever,cough, loss of taste or smell etc.) are excluded whilst symptoms persist.
  • 2. Total bilirubin >2.0 x ULN using the average of two baseline measures.
  • 3. Screening ALT > 6x ULN in a single baseline measure or ALT > 5x ULN using the average of two baseline measures.
  • 4. Participants with abnormal liver biochemistry (ALT, aspartate aminotransferase [AST], ALP, or total bilirubin) during the Screening period (at Visit 1 or Visit 2) and the variance between these two samples for the abnormal parameter is >40%.
  • 5. Screening estimated glomerular filtration rate (eGFR) <30 mL/min/1.73m2 based on CKD-EPI equation.
  • 6. History or presence of hepatic decompensation (e.g., variceal bleeding, hepatic encephalopathy or ascites).
  • 7. Presence of actively replicating viral hepatitis B or C (HBV, HCV) infection, primary sclerosing cholangitis (PSC), alcoholic liver disease and/or confirmed hepatocellular carcinoma or biliary cancer.

  • 13. Primary sleep disorders such as but are not limited to sleep apnea,narcoleptsy,hypersomnia
  • 14. Any current malignancies (including hematologic and solid malignancies).

  • 18. Any current medical condition (e.g. senility or dementia), which may affect the participant's ability to comply with the protocol specified procedures.
  • Prior/Concomitant Therapy

  • 20. Use of obeticholic acid: within 8 weeks prior to Screening
  • 21. Initiation, discontinuation or change in dose of bezafibrate or fenofibrate at any time during the 8 weeks prior to Screening.
  • 22. Initiation, discontinuation, or change in dose of any of the following in the 8 weeks prior to Screening: bile acid binding resins, rifampicin, naltrexone, naloxone, nalfurafine, pregabalin, gabapentin, sertraline or other SSRIs.
  • 23. Initiation, discontinuation or change in dose of opioids, regardless of indication, in the 8 weeks prior to Screening.
