About this trial

This is an interventional treatment trial for Progressive Familial Intrahepatic Cholestasis (PFIC) focused on measuring Cholestasis, Maralixibat, Mutation

Eligibility Criteria

undefined - 18 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Informed consent and assent (as applicable for participants less than or equal to (<=) 18 years per Institutional Review Board/Ethics Committee (IRB)/Ethics Committee (EC) as appropriate.

    a. Primary cohort: i. Participants with 2 documented mutant alleles in ABCB11 (PFIC2); participants without bile salt export pump (BSEP) function (biallelic truncating mutations in ABCB11) will not be enrolled into the primary cohort. b. Exploratory cohort: i. Participants with PFIC1/3/4 or PFIC2 with biallelic truncating mutationsiii.Infants from birth to <12 months of age with PFIC ii.
