FDA Fast Track for Sangamo Therapies
FDA has granted Sangamo Therapeutics a fast track designation for SB-318 and SB-913, two clinical stage in vivo genome editing product candidates for treating Mucopolysaccharidosis Type I (MPS I) and MPS II, respectively. MPS I and MPS II are caused by mutations in the genes encoding alpha-L-iduronidase (IDUA) and iduronate 2-sulfatase (IDS) enzymes, respectively, according to the company. The products were designed using Sangamo’s zinc finger nuclease genome editing technology as single treatments intended to provide stable, continuous production of the enzymes for the lifetime of the patient, it says. They both have already received orphan drug and rare pediatric disease designations from the agency.
