Orchard Therapeutics Announces New OTL-201 Clinical Data in Sanfilippo Syndrome Type A (MPS-IIIA) Accepted for Oral Presentation at 62nd American Society of Hematology Annual Meeting
BOSTON and LONDON,
“MPS-IIIA is a progressive, life-threatening metabolic disease with no approved treatment options,” said Professor
Preliminary results from the first patient treated with OTL-201 show evidence of engraftment of gene-modified cells, supra-physiological N-sulphoglucosamine sulphohydrolase (SGSH) enzyme expression in multiple lineages, and reduction of heparan sulfate in plasma, cerebrospinal fluid and urine over an initial three-month follow-up period. Additional follow-up data and an update on the trial status will be shared at the time of the oral presentation.
Oral Presentation Details:
Ex-Vivo Autologous Stem Cell Gene Therapy Clinical Trial for Mucopolysaccharidosis Type IIIA: Trial in Progress – NCT04201405
Publication number: 676
Session: 801. Gene Editing, Therapy and Transfer I

About OTL-201 and MPS-IIIA
Mucopolysaccharidosis type IIIA (MPS-IIIA, also known as Sanfilippo syndrome type A) is a rare and life-threatening metabolic disease. People with MPS-IIIA are born with a mutation in the N-sulphoglucosamine sulphohydrolase (SGSH) gene, which, when healthy, helps the body break down sugar molecules called mucopolysaccharides, including heparan sulfate. The buildup of mucopolysaccharides in the brain and other tissues leads to intellectual disability and loss of motor function. MPS-IIIA occurs in approximately one in every 100,000 live births. Life expectancy of children born with MPS-IIIA is estimated to be between 10-25 years.1 There are currently no approved treatment options for MPS-IIIA. OTL-201 is an investigational ex vivo autologous hematopoietic stem cell gene therapy being studied for the treatment of MPS-IIIA. It uses a modified virus to insert a functional copy of the SGSH gene into a patient’s cells.
