Receives Best of Liver Meeting distinction.\n- RISE study in infants with ALGS shows safety and tolerability of LIVMARLI for ages ≥2 months.\n- Real-world evidence highlights LIVMARLI’s safety and tolerability in patients with ALGS.\n- Post-AASLD conference call to discuss MARCH data on November 9, 2022 at 8am ET/5am PT\n\n FOSTER CITY, Calif.--(BUSINESS WIRE)--\nMirum Pharmaceuticals, Inc. (Nasdaq: MIRM), today presented new data from LIVMARLI® (maralixibat) oral solution studies, including two late-breaker presentations, at The Liver Meeting® of the American Association for the Study of Liver Diseases taking place November 4-7, 2022 in Washington, D.C.\n\n“The MARCH-PFIC data provides comprehensive evidence that LIVMARLI is a potentially meaningful treatment option for patients with progressive familial intrahepatic cholestasis (PFIC). The statistically significant reduction in pruritus and serum bile acids, as well as improvements in bilirubin and growth, demonstrate a magnitude of treatment effect which exceeded expectations, suggesting higher doses not only improves response rates, but is also effective across PFIC types,” said Pam Vig, PhD, head of R&D at Mirum. “We look forward to discussing these data with regulatory agencies soon. In addition, interim safety data in Alagille syndrome (ALGS) underscores LIVMARLI’s safety and tolerability profile in infants as young as two months of age. We are thrilled to expand the growing body of clinical evidence for LIVMARLI in both PFIC and ALGS and to present our late breaking data at the AASLD conference.”\n\nOral session #5001: Efficacy and safety of maralixibat in patients with progressive familial intrahepatic cholestasis (MARCH-PFIC): a randomized placebo-controlled study\n**Nominated for Best of Liver Meeting**\nLate-breaker oral presentation by Professor Richard J. Thompson, King’s College, London\n\nThe Phase 3 MARCH study evaluated LIVMARLI 570 µg/kg BID in 93 patients across a broad range of PFIC types between ages one to 17 years old.

The full-study population of 93 patients wa...
