YONGIN, South Korea, April 4, 2019 /PRNewswire/ -- Clinigen K.K. and GC Pharma (formerly known as Green Cross Corporation) (KRX: 006280) today announced an exclusive licensing agreement in Japan to commercialize Hunterase (Idursulfase-beta) ICV, a human recombinant iduronate-2-sulfatase (IDS) used in enzyme replacement therapy for the treatment of Hunter syndrome. Used as one of the methods for Hunter syndrome treatment, intravenous injection does not penetrate the blood brain barrier in clinically adequate amounts. Hunterase (Idursulfase-beta) ICV developed by GC Pharma is delivered directly to cerebral ventricles by intracerebroventricular (ICV) administration, in order to reach the cells of the brain and central nervous system. Hunterase (Idursulfase-beta) ICV is expected to meet the unmet needs of severe patients in improving their quality of life, as a method that can achieve what previous intravenous injection could not. The Phase 1/2 clinical trial conducted as an investigator-initiated trial by Prof. Torayuki Okuyama in National Center for Child Health and Development in Japan showed a significant decrease in Heparan sulfate which causes mental retardation.

About Hunter syndrome
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 (ERT) or palliative care.
