New study analyzes Odevixibat's impact on rare liver disease outcomes

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Part A Eligibility: Comparisons to Evaluate the Effect of Odevixibat Versus SBD-naïve Odevixibat Cohort: * Patients treated with odevixibat in A4250-005 with at least one post-odevixibat assessment and who did not have prior LT or SBD. OR * Patients treated with placebo in A4250-005, first received odevixibat in Cohort 1 of A4250-008 with at least one post-odevixibat assessment, and meet the additional eligibility criteria OR * Patients treated with odevixibat in Cohort 2 of A4250-008 with at least one post-odevixibat assessment and who meet the additional eligibility criteria External Control Cohort: * A male or female patient in NAPPED registry not enrolled in A4250-005 or A4250-008. * The patient must be IBAT inhibitor-naïve (has not received prior treatment with odevixibat, maralixibat, or other IBAT inhibitors). * Patients must have clinical genetic confirmation of PFIC (any type), excluding known pathologic variations of the ABCB11 gene that predict complete absence of the BSEP protein. * The patient has at least one visit in NAPPED (the first of which becomes the Day 1 visit for this cohort) where they meet the eligibility criteria * Patients must be in the regions that participated in A4250-008. Part B Eligibility: Comparisons to Evaluate the Effect of Odevixibat Versus SBD Odevixibat Cohort * Same as Part A External Control Cohort: * A male or female patient in NAPPED registry with clinical diagnosis of PFIC (any type) and not enrolled in A4250-005 or A4250-008. * The patient must be IBAT inhibitor-naïve (has not received prior treatment with odevixibat, maralixibat, or other IBAT inhibitors). * Patient must have clinical genetic confirmation of PFIC (any type), excluding known pathologic variations of the ABCB11 gene that predict complete absence of the BSEP protein; * The patient underwent SBD (the date of surgery becomes the Day 1 visit for this cohort) but did not previously undergo a LT. * The patient meets the additional eligibility criteria. * Patients must be in the regions that participated in A4250-008.
