About LIVMARLI

LIVMARLI (CAN108 (maralixibat)) is a minimally absorbed ileal bile acid transporter (IBAT) inhibitor that blocks the enterohepatic circulation of bile acids, reduces bile acid levels in the liver and serum, reduces the resultant liver injury and relieves pruritus (extreme itching). LIVMARLI is the first, and only medication approved in China, the US and EU to treat cholestatic pruritus associated with Alagille syndrome (ALGS).

In addition to ALGS, LIVMARLI is under clinical development by CANbridge for the treatment of other cholestatic liver diseases, including progressive familial intrahepatic cholestasis (PFIC) and biliary atresia (BA), and has been granted Orphan Drug designation by the FDA.

CANbridge acquired the exclusive right to develop, commercialize and manufacture, under certain conditions, LIVMARLI in Greater China from Mirum Pharmaceuticals, Inc. for ALGS, PFIC and BA, and select other indications. LIVMARLI has been approved for marketing by China’s National Medical Products Administration (NMPA) for the treatment of cholestatic pruritus in patients with Alagille syndrome (ALGS) I year of age and older.

About Alagille Syndrome (ALGS)

Alagille syndrome (ALGS) is an autosomal dominant multisystem disorder which can lead to end-stage liver disease and death. Its incidence is between 1/30,000 and 1/50,000 [1]. It has been registered in National Rare Diseases Registry System of China (NRDRS). This disease is characterized by dysplasia of bile ducts and involvement of extrahepatic organs, such as the kidneys and eyes, as well as bones and the cardiovascular system. 100% of patients experience liver involvement [2, 3], which often manifests as chronic cholestasis (slowed or stalled bile flow), usually in the neonatal period or within the first 3 months after birth. In addition to jaundice, skin xanthoma and hepatomegaly, patients will also experience severe pruritus [4], which can lead to skin disfigurement, emotional disorder, sleep deprivation and interruption of school learning, due to scratching in affected children [5]. It seriously affects the growth, development and quality of life of patients [6] and can lead to liver transplantation [7].
