Who We Are

Mirum is a Latin word that means extraordinary, amazing or remarkable. We chose Mirum as our company name because it speaks to the impact we hope we can make for patients and their families.


About Mirum

Our pipeline consists of two apical sodium-dependent bile acid transporter (ASBT) inhibitors which are being studied across six cholestatic liver diseases in children and adults.

Maralixibat is an orally administered medication in clinical development for children with Alagille syndrome (ALGS), progressive familial intrahepatic cholestasis (PFIC), and biliary atresia.

In addition, we are evaluating volixibat, also an oral drug, in clinical studies for the treatment of cholestatic diseases including primary sclerosing cholangitis (PSC), intrahepatic cholestasis of pregnancy (ICP), and primary biliary cholangitis (PBC).

Each of these conditions, if left untreated, can lead to serious complications including a significant impact to the quality of life for both patients and their families.

Working closely with patients and caregiver communities, we intimately understand the challenges of living with cholestatic liver diseases. Based on a wealth of data from clinical trials spanning many years and patients, we believe our approach can address the underlying cause of symptoms and liver damage. Our goal is to give families their lives back.


Mirum has assembled some of the world’s top experts in liver disease and pharmaceutical development with significant experience in liver and rare diseases and progressing products from early stage research to clinical trials and ultimately to regulatory approval and commercialization.
