Recruitment & Eligibility

• Status: Authorised-recruitment may be ongoing or finished
• Sex: All
• Target Recruitment: 161

Inclusion Criteria

1)Must have provided written informed consent and agree to comply with the study protocol
2)Males or females age of 18 to 75 years inclusive at first Screening Visit (SV)
3)PBC diagnosis as demonstrated by the presence of = 2 of the following 3 diagnostic criteria:
a.History of elevated ALP levels for = 6 months prior to randomization (V1)
b.Positive anti-mitochondrial antibodies (AMA) titers (> 1/40 on immunofluorescence or M2 positive by enzyme-linked immunosorbent assay [ELISA]) or positive PBC-specific antinuclear antibodies (ANA)
c.Liver biopsy consistent with PBC
4)ALP = 1.67 x ULN
5)TB = 2x ULN
To ensure inclusion of a relevant ratio of patients with substantial risk of
long-term clinical outcomes or moderate disease stage, approximately 10% of randomized patients will be moderately advanced per Rotterdam Criteria (TB > ULN or Albumin < lower limit of normal [LLN]) and approximately 20% will have a TB > 0.6 x ULN (patients at risk of progression)
6)Must have at least 4 available values for PBC Worst Itch Numeric Rating Scale (NRS) during each of the 7 day intervals in the 14 days prior to randomization (V1), for a total of at least 8 values for PBC Worst Itch NRS in the last 14 days prior to randomization (V1)
7)UDCA for at least 12 months (stable dose = 3 months) prior to screening, or unable to tolerate UDCA treatment (no UDCA for = 3 months) prior to screening (per country standard-of-care dosing)
8)If on colchicine must be on a stable dose for = 3 months prior to screening
9)Medications for management of pruritus (e.g., cholestyramine, rifampin, naltrexone or sertraline) must be on a stable dose for = 3 months prior to screening
10)Patients taking statins or ezetimibe must be on a stable dose for = 2 months prior to screening
11)Females participating in this study must be of non-child bearing potential or must be using highly effective contraception for the full duration of the study and for 1 month after the last drug intake:
•Non-child bearing potential: Cessation of menses for at least 12 months
due to ovarian failure or surgical sterilization such as bilateral oophorectomy, or hysterectomy
•Highly effective contraception methods include:
a.Combined (estrogen and progrestogen containing) hormaonal contraception associated with inhibition of ovulation, oral, intravaginal or transdermal
b.Progestogen-only hormonal contraception associated with inhibition of ovulation, oral, injectable or implantable
c.Intrauterine device (IUD)
d.Intrauterine hormoine release system (IUS)
e.Bilateral tubal occlusion
f.Vasectomized partner
g.Sexual abstinence, if required by local IRB/IEC regulations and/or considered adequate by National laws (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient)
12)For patients who consent to have liver biopsy samples collected, patients in whom it is safe and practical to proceed with a liver biopsy, and who agree to have:
a.1 liver biopsy during the Screening Period (if no historical biopsy within 6 months before screening is available)
b.1 liver biopsy after 52-weeks of treatment
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 119
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 42

Exclusion Criteria

1)History or presence of other concomitant liver disease including:
a)Positive anti-hepatitis A virus (HAV) immunoglobulin M (IgM) antibodies or positive hepatitis B surface antigen (HBsAg) or positive anti-hepatitis C virus (HCV) ribonucleic acid (RNA) (tested for in case of known cured HCV infection or positive HCV Ab at screening)
b)Primary sclerosing cholangitis (PSC)
c)Alcoholic liver disease (ALD)
d)Autoimmune hepatitis (AIH) or if treated for an overlap of PBC with AIH, or if there is suspicion and evidence of overlap AIH features, that cannot be explained alone by insufficient response to UDCA
e)Nonalcoholic steatohepatitis (NASH)
f)Gilbert’s Syndrome (exclusion due to interpretability of bilirubin levels)
g)Known history of alpha-1 antitrypsin deficiency
2)Clinically significant hepatic decompensation, including:
a)History of liver transplantation, current placement on a liver transplant list, current Model for End-Stage Liver Disease-Sodium (MELD-Na) score = 12 linked to hepatic impairment

4)Patient has a positive test for Human Immunodeficiency Virus (HIV) Type 1 or 2 at screening, or patient is known to have tested positive for HIV
