CANbridge Pharmaceuticals’ Hunterase® Granted Priority Review by the Chinese National Medical Products Administration


Beijing, Shanghai, China, September 10, 2019—CANbridge Pharmaceuticals Inc., a biopharmaceutical company developing innovative drug candidates to treat underserved medical conditions in China and other markets, announced that the National Medical Products Administration (NMPA) of China granted Priority Review to Hunterase (idursulfate beta), a human recombinant iduronate-2-sulfatase (IDS) enzyme replacement therapy, for the treatment of Hunter syndrome (mucopolysaccharidosis type II). Hunter syndrome is a rare, disabling and life-threatening genetic disease, which has a higher prevalence in Asia than in other parts of the world. CANbridge recently submitted a Hunterase New Drug Application (NDA) to the NMPA. The Chinese government has included mucopolysaccharidosis on the “First National List of Rare Diseases” as a disease group to target. There is no approved treatment for Hunter syndrome in China.

“The Priority Review designation, solely granted to therapies that address unmet medical conditions with some level of clinical urgency, validates our choice of Hunterase as the first rare disease candidate we plan to commercialize,” said James Xue, Ph.D., Founder, Chairman and CEO, CANbridge Pharmaceuticals Inc. “Hunterase is approved in 10 countries. We are now one step closer to being able to bring the same treatment option to Hunter syndrome patients, and their families, in China.”


About Hunter syndrome

Hunter syndrome (MPS II) is an inherited lysosomal storage disease that is X-linked and occurs primarily in boys. It causes an enzyme deficiency that interferes with the body’s ability to break down certain complex sugar polymers, called glycosaminoglycans, resulting in serious skeletal, tissue, neurological and multi-organ complications and, ultimately, a shortened lifespan. Hunter syndrome occurs in approximately 1 in every 149,000 to 162,000 live births in Caucasian countries. The rate in East Asian countries, however, is higher, occurring in approximately 1 in 51,000 to 93,000 live births in Taiwan. There is no cure currently. The standard treatments are enzyme replacement therapy (ERT) or palliative care. Mucopolysaccharidosis is one of the 121 diseases on the “First National List of Rare Diseases” published by the Chinese government.
