Odevixibat Outcomes in Patients With PFIC Versus an External Control Cohort (OvEC-PFIC)
brief summary
Progressive familial intrahepatic cholestasis (PFIC) is a rare inherited liver disease that causes a build-up of bile acids in the liver. This can lead to severe itching (pruritus), poor sleep, impaired growth, liver damage, and in some cases the need for surgery or liver transplantation. The purpose of this non-interventional, retrospective study is to compare long-term health outcomes in patients with PFIC. The comparison is between patients who received odevixibat in two odevixibat clinical trials (Studies A4250-005 and A4250-008) and an aligned, balanced external control cohort of patients with PFIC from the Natural course and Prognosis of PFIC and Effect of biliary Diversion (NAPPED) registry who were not treated with odevixibat (or other ileal bile acid transporter \[IBAT\] inhibitors). Outcomes such as liver transplantation, death, and surgical biliary diversion (SBD) will be examined to better understand how treatment with odevixibat compares to the natural course of PFIC. This study aims to provide a robust comparative evaluation of long-term clinical outcomes with odevixibat.
detailed description
This study analysis consists of two parts: Part A will evaluate the effect of odevixibat on clinical outcomes in patients without prior SBD (i.e., SBD-naïve) who were treated with odevixibat versus SBD-naïve external controls who were not treated with odevixibat; Part B will evaluate the effect of odevixibat on clinical outcomes by comparing outcomes in patients without prior SBD who were treated with odevixibat versus external controls who underwent SBD and were not treated with odevixibat.
