FOSTER CITY, Calif.–(BUSINESS WIRE)–
Mirum Pharmaceuticals, Inc. (Nasdaq: MIRM), a biopharmaceutical company focused on the development and commercialization of novel therapies for debilitating liver diseases, today announced financial results and a corporate update for the quarter ended September 30, 2020.

“This quarter marked several milestones toward providing better treatment options for Alagille syndrome and PFIC, with the initiation of our rolling NDA submission, the launch of an expanded access program, and presentation of five-year transplant free survival data in PFIC2,” said Chris Peetz, president and chief executive officer of Mirum. “Looking forward to next year, we are planning for the U.S. launch of maralixibat in Alagille syndrome and the expansion of our programs, with upcoming study starts in biliary atresia, primary sclerosing cholangitis and intrahepatic cholestasis of pregnancy, all settings with high disease burden and no currently approved therapies.”

Key Operational Highlights

  • Presented five-year transplant-free survival data for patients with PFIC2 at Digital International Liver Congress (EASL).
  • Initiated rolling submission of New Drug Application (NDA) to U.S. Food and Drug Administration (FDA) for maralixibat for the treatment of cholestatic pruritus in patients with Alagille syndrome (ALGS).
  • Launched maralixibat Expanded Access Program (EAP) for the treatment of cholestatic pruritus associated with ALGS in United States, Canada, Australia, and 10 countries in Europe.
  • Announced partnership with EVERSANA™ to support the planned launch and commercialization of maralixibat in ALGS in the United States, if approved.
  • Received Orphan Drug Designation from the U.S. FDA for maralixibat in biliary atresia; Phase 2 study initiation planned for the first quarter of 2021.
  • Received rare pediatric disease designation for maralixibat for the treatment of PFIC.

Third Quarter 2020 Financial Results

  • Total operating expenses for the quarter ended September 30, 2020 were $21.7 million, compared to $15.9 million for the third quarter of 2019.

    • Research and development expenses were $16.0 million, compared to $12.2 million for the comparable prior-year period. This increase was primarily due to increased personnel related expenses, manufacturing activities to support Mirum’s NDA, and higher consulting expenses.
    • General and administrative expenses were $5.7 million, compared to $3.7 million for the comparable prior-year period. The increase was primarily due to personnel and other compensation related expenses.
  • For the quarter ended September 30, 2020, Mirum reported a net loss of $21.5 million, or $0.86 per share, compared with a net loss of $15.1 million, or $0.84 per share for the same period in 2019.

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, 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. In a Phase 2 PFIC study, a genetically defined subset of BSEP (bile salt export pump) deficient (PFIC2), patients responded to maralixibat. The FDA has granted maralixibat Breakthrough Therapy designation for 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 adverse events were diarrhea and abdominal pain.
