BEIJING & CAMBRIDGE, Mass.–(BUSINESS WIRE)–EdiGene, Inc., which develops genome editing technologies to accelerate drug discovery and develop novel therapeutics for a broad range of diseases, will present data on its lead therapeutic program for patients with the most severe form of mucopolysaccharidosis type I (MPS I), known as Hurler syndrome, at the 23rd American Society of Gene & Cell Therapy (ASGCT) Annual Meeting on Tuesday, May 12, 2020 at 10:15 a.m. EDT.
MPS I is a rare and potentially fatal lysosomal storage disorder that can affect organs and tissue throughout the body. It is a genetic condition that results in a deficiency of the enzyme α-L-iduronidase (IDUA). As a result, metabolic waste accumulates in cells and cause progressive damage. There is no cure for MPS I. Patients today are either treated with a bone marrow transplant or enzyme replacement therapy.
Over 40% of the patients with Hurler syndrome, are caused by presence of W402X (c1205 G ->A point mutation) in IDUA. EdiGene’s therapeutic program for these patients uses LEAPER™(Leveraging endogenous ADAR for programmable editing of RNA), a novel RNA base editing technology. Oligonucleotides of various design, called arRNA, were developed to produce precise and sequence specific A-to-I conversion in the mRNA sequence for codon 402, leading to generation of the wild type IDUA mRNA and protein. Data showed significant IDUA enzymatic activity with long duration in MPS I patient-derived cells.
“Even with the current standard of care, unmet needs remain for patients with Hurler Syndrome,” said Dong Wei, Ph.D., CEO of EdiGene, “The pre-clinical data suggest encouraging progress for our program, and we hope to further develop it into a potential treatment for these patients.”
LEAPER™ is developed by Professor Wensheng Wei’s lab at Peking University. Professor Wei, who is also the founder of EdiGene, commented: “LEAPER™ is a robust, precise and efficient editing technology with versatility across multiple delivery platforms. It is uniquely positioned for in vivo genome editing treatment for selected diseases and we will dedicate ourselves to turning this technology into therapies for patients in need.”
