Publication number: 20210015906Abstract: The present disclosure relates to compositions and methods for treating Sanfilippo syndrome (also known as Sanfilippo disease type D, Sanfilippo D, mucopolysaccharidosis type IIID, MPS IIID). The method can entail injecting to the spinal fluid of a MPS IIID patient an effective amount of a composition comprising a recombinant human acetylglucosamine-6-sulfatase (GNS) protein comprising the amino acid sequence of SEQ ID NO: 1 or an amino acid sequence having at least 90% sequence identity to SEQ ID NO: 1 and having the enzymatic activity of the human GNS protein. The composition can be provided in an artificial cerebrospinal fluid. About 1 mg to about 100 mg of the recombinant polypeptide may be administered to the patient once every 2 weeks to 6 months.Type: ApplicationFiled: July 1, 2020Publication date: January 21, 2021Inventors: Patricia Dickson, Tsui-Fen Chou, Sean Ekins, Shih-Hsin Kan, Steven Le, Derek R.
