– LIVMARLI PFIC primary analysis from MARCH study awarded prestigious Gerard Odell Prize for Excellence in Pediatric Hepatology Research
– 15 abstracts demonstrating robust clinical findings from LIVMARLI studies and real-world experience in ALGS and PFIC
FOSTER CITY, Calif.–(BUSINESS WIRE)–#alagillesyndrome–Mirum Pharmaceuticals, Inc. (NASDAQ: MIRM) today announced the presentation of a series of analyses demonstrating further benefit of LIVMARLI® (maralixibat) oral solution in patients with cholestatic pruritus associated with Alagille syndrome (ALGS) and for patients with progressive familial intrahepatic cholestasis (PFIC), two rare debilitating liver diseases. LIVMARLI is the first medication approved by the U.S. Food and Drug Administration (FDA) to treat cholestatic pruritus in patients with ALGS, and the only to be approved for patients three months of age and older.
Data presented during NASPGHAN demonstrated continued evidence of the impact of LIVMARLI for patients with PFIC as well as both clinical data and real-world use of LIVMARLI in patients with ALGS. Presentations included:
PFIC:
- Data from the MARCH PFIC Phase 3 Study was awarded the prestigious Gerard Odell prize for Excellence in Pediatric Hepatology Research. The MARCH PFIC clinical trial was conducted across the broadest range of PFIC types ever studied. Key data from the study demonstrated significant, rapid, and clinically meaningful improvements in pruritus and serum bile acids (sBA) along with significant improvements in bilirubin and weight z-scores.
- Other key PFIC data included analyses on bilirubin normalization, improvement in sleep, long term maintenance of efficacy from the MARCH-ON extension study, and results from the FIC1 genetic cohort.
ALGS:
- Real-world data in patients with ALGS was presented on adherence to LIVMARLI as well as reduction of other medications and vitamin supplementation while on LIVMARLI. In addition, case studies on delay of liver transplant due to significant reductions in pruritus, and quality of life were shown.
- Other key ALGS data included clinically meaningful reductions in the number and severity of xanthomas, and improvement in pruritus and maintenance of effect in adult patients with ALGS.
“The extensive data being presented at NASPGHAN continues to underscore the impact of LIVMARLI across these pediatric cholestatic indications, and we are excited about what this means for the patient community,” said Pam Vig, PhD, head of research and development at Mirum. “The body of research presented at this conference advances our understanding of LIVMARLI’s clinical effect, which is critical for disease management in the real-world setting.”

About LIVMARLI® (maralixibat) oral solution
LIVMARLI® (maralixibat) oral solution is an orally administered, once-daily, ileal bile acid transporter (IBAT) inhibitor and the only approved medication by the U.S. Food and Drug Administration for the treatment of cholestatic pruritus in patients with Alagille syndrome (ALGS) three months of age and older.
LIVMARLI is also the only approved IBAT inhibitor approved by the European Commission for the treatment of cholestatic pruritus in patients with ALGS two months and older, and by Health Canada for the treatment of cholestatic pruritus in ALGS.

Mirum has also submitted LIVMARLI for approval in the U.S. in cholestatic pruritus in PFIC patients three months of age and older, and in Europe, in PFIC for patients two months of age and older.
LIVMARLI is currently being evaluated in late-stage clinical studies in other rare cholestatic liver diseases including biliary atresia. LIVMARLI has received Breakthrough Therapy designation for ALGS and PFIC type 2 and orphan designation for ALGS, PFIC and biliary atresia.

IMPORTANT SAFETY INFORMATION
LIVMARLI can cause side effects, including:
Changes in liver tests. Changes in certain liver tests are common in patients with Alagille syndrome and can worsen during treatment with LIVMARLI. These changes may be a sign of liver injury and can be serious. Your healthcare provider should do blood tests before starting and during treatment to check your liver function. Tell your healthcare provider right away if you get any signs or symptoms of liver problems, including nausea or vomiting, skin or the white part of the eye turns yellow, dark or brown urine, pain on the right side of the stomach (abdomen) or loss of appetite.
Stomach and intestinal (gastrointestinal) problems. LIVMARLI can cause stomach and intestinal problems, including diarrhea, stomach pain, and vomiting during treatment. Tell your healthcare provider right away if you have any of these symptoms more often or more severely than normal for you.
A condition called Fat Soluble Vitamin (FSV) Deficiency caused by low levels of certain vitamins (vitamin A, D, E, and K) stored in body fat. FSV deficiency is common in patients with Alagille syndrome but may worsen during treatment. Your healthcare provider should do blood tests before starting and during treatment.
