The Food and Drug Administration (FDA) has granted Orphan Drug designation to Sangamo’s genome editing product candidate, SB-913, for the treatment of Mucopolysaccharidosis Type II (MPS II).

MPS II is a rare lysosomal storage disorder caused by mutations in the gene encoding the iduronate 2-sulfatase (IDS) enzyme. Sangamo is utilizing its proprietary zinc finger nuclease (ZFN) in vivo genome editing technology to develop SB-913 as a single treatment approach to provide a lifetime, stable, continuous production of the IDS enzyme.
