Data from the Phase 2 INDIGO study evaluating maralixibat for pediatric patients with PFIC2 served as the basis of the MAA submission. Mirum recently announced data showing five-year transplant-free survival for patients who achieved serum bile acid control. The data also demonstrated improvements across multiple parameters including pruritus control, improvements of liver enzyme and bilirubin levels, and improvement in growth. These data were presented at the annual meeting of the

About Maralixibat
Maralixibat is a novel, minimally absorbed, orally administered investigational drug being evaluated in several cholestatic liver diseases. Maralixibat inhibits the apical sodium-dependent bile acid transporter (ASBT), resulting in more bile acids being excreted in the feces, leading to lower levels of bile acids systemically, thereby potentially reducing bile acid mediated liver damage and related effects and complications. More than 1,600 individuals have received maralixibat, including more than 120 children who have received maralixibat as an investigational treatment for Alagille syndrome (ALGS) and progressive familial intrahepatic cholestasis (PFIC). In the ICONIC Phase 2b ALGS clinical trial, patients taking maralixibat had significant reductions in bile acids and pruritus compared to placebo, as well as reduction in xanthomas and accelerated growth long-term. In a Phase 2 PFIC study, a genetically defined subset of BSEP deficient (PFIC2), patients responded to maralixibat. The
