The abstracts from the meeting are available on the Journal of Pediatric Gastroenterology and Nutrition website.

Virtual Symposium
"Solving the Puzzle of Pediatric Cholestasis"
November 2, 2020 – 4:30-6:00 p.m. ET

Mirum will be sponsoring a virtual symposium led by Dr. Philip Rosenthal with presentations on Alagille syndrome (ALGS), Progressive Familial Intrahepatic Cholestasis (PFIC) and Biliary Atresia (BA), by Dr. Binita Kamath and Dr. Richard Thompson. To attend the symposium, you must be registered for NASPGHAN. Once registered, the congress will email an invitation to the event.

"We are pleased to share data from our maralixibat studies at the NASPGHAN meeting as it provides a forum for scientific exchange with leaders in the pediatric gastroenterology and hepatology community who treat children with rare diseases like ALGS and PFIC," said Chris Peetz, president and chief executive officer of Mirum. "The data demonstrate long-term treatment success of more than five years for patients with pruritus associated with ALGS, based on findings from the ICONIC study. Also being shared are data highlighting five-year transplant-free survival in patients with PFIC2 who responded to maralixibat. These data underscore our confidence in maralixibat to be a medicine that has the potential to change the treatment paradigms for ALGS and PFIC2."

About Maralixibat

Maralixibat is a novel, minimally absorbed, orally administered investigational drug being evaluated in several rare 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 FDA has granted maralixibat Breakthrough Therapy designation for treatment of pruritus associated with ALGS in patients one year of age and older and for PFIC2. Maralixibat was generally well-tolerated throughout the studies. The most frequent treatment-related adverse events were diarrhea and abdominal pain. Until maralixibat is approved by the FDA and available for prescribing, the medication is available to eligible patients with ALGS through Mirum’s expanded access program.
