9 January 2019 - - Chinese biopharmaceutical company CANbridge Pharmaceuticals Inc. and South Korea-based GC Pharma (formerly known as Green Cross Corp.) (KRX:006280), have inked an exclusive licensing agreement in the greater China area to commercialise Hunterase, a human recombinant iduronate-2-sulfatase enzyme replacement therapy for the treatment of Hunter syndrome. Developed by GC Pharma, Hunterase is marketed in more than ten countries worldwide, the company said.

There is no approved treatment for Hunter syndrome in China, unlike in some parts of the world.

Hunter syndrome (Mucopolysaccharidosis type II) is an inherited lysosomal storage disease that occurs primarily in boys. It causes an enzyme deficiency that interferes with the body's ability to break down certain complex sugars, resulting in serious skeletal, tissue, neurological and multi-organ complications and, ultimately, death.

It occurs in approximately 1.3 out of 100,000 male newborns.

There is no cure. The standard treatments are enzyme replacement therapy or palliative care. Mucopolysaccharidosis is one of the 121 diseases on the China Rare Disease List recently published by the Chinese government.

GC Pharma is a biopharmaceutical company that delivers life-saving and life-sustaining protein therapeutics and vaccines.

Headquartered in South Korea, GC Pharma is one of the largest protein products manufacturers in the world and has been dedicated to quality healthcare solutions more than half a century. Green Cross Corp. updates its corporate brand as GC Pharma in early 2018.

Green Cross Corp. remains the company's registered, legal name.
