About CAN108 (maralixibat)

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. Maralixibat is the first and, currently, only FDA-approved medication to treat cholestatic pruritus associated with Alagille syndrome (ALGS).

In addition to ALGS, Maralixibat is under clinical development for the treatment of other cholestatic liver diseases, including progressive familial intrahepatic cholestasis (PFIC) and biliary atresia (BA), and has been granted Breakthrough Therapy Designation by the FDA.

CANbridge acquired the exclusive right to develop and commercialize CAN108 in Greater China from Mirum Pharmaceuticals, Inc. for ALGS, PFIC and BA. CAN108’s New Drug Application (NDA) for ALGS has been accepted and granted priority review by China’s National Medical Products Administration (NMPA).
