Gene editing holds promise for treating neuromuscular disorders such as limb-girdle muscular dystrophy, but its clinical translation remains challenging due to a lack of complementary delivery tools for the extensive network of skeletal muscles in the human body. A team at University of Massachusetts Chan Medical School compared editing outcomes mediated by either Cas9 mRNA and RNP delivery to skeletal muscle via local injection in the context of the previously described selective organ targeting (SORT) lipid nanoparticles (LNPs) platform.
Tessera Therapeutics Inc. has received a grant from the Gates Foundation to support early-stage research exploring multiple genetic approaches aimed at developing a scalable cure for HIV. This research will evaluate several potential strategies leveraging Tessera’s Gene Writing platform to engineer immune cells in vivo.
GM1 gangliosidosis is a lysosomal storage disease caused by mutations in the human GLB1 gene, encoding the ubiquitous lysosomal β-galactosidase. GM1 causes a rapidly progressing neurodegeneration, which can be lethal in the first 2 years of life in the most severe cases.
Glucocerebrosidase (GCase), encoded by the gene GBA1, is a ubiquitous lysosomal enzyme that breaks down lipid substrates, glucosylceramide (GL-1) and glucosylsphingosine (Lyso-GL1), into glucose and ceramide. Loss-of-function mutations in GBA1 reduce GCase activity, resulting in lipid accumulation within lysosomes and subsequent lysosomal dysfunction.
Friedreich’s ataxia (FA) is an inherited neurodegenerative disorder caused by GAA repeat expansions in the FXN gene, which produces a mitochondrial protein vital for iron-sulfur cluster assembly and energy metabolism. Researchers at Solid Biosciences Inc. presented preclinical data supporting the first-in-human trial on SGT-212 gene therapy in FA models.
Entering its first major cardiovascular disease collaboration with a biopharma company, while it advances two internal gene therapies, Tenaya Therapeutics Inc. signed on with Alnylam Pharmaceuticals Inc. to deliver up to 15 novel genetic targets that could lead to new heart disease medicines. The deal comes with $10 million up front, and up to $1.13 billion is available to South San Francisco-based Tenaya if all targets meet certain milestones, leading to approved therapeutics that Alnylam develops and commercializes.
Cure Rare Disease has entered into a multiyear partnership with the LGMD2L Foundation to develop a gene replacement therapy for anoctamin 5 (ANO5)-related disease, a rare genetic disorder.
Tessera Therapeutics Inc.’s lead in vivo gene editing program, TSRA-196, has been awarded orphan drug and fast track designations by the FDA for adults with α-1 antitrypsin deficiency (AATD).
A new study by researchers at Stanford University and collaborating institutions aimed to investigate the safety and efficiency of lipid nanoparticle-mediated Cas13d mRNA delivery to uveal melanoma cells.
