Rznomics Inc. scored a potential ₩1.9 trillion (US$1.35 billion) global license option agreement with Eli Lilly and Co. to codevelop a novel RNA editing gene therapy to treat hereditary hearing loss.
Using a customized gene editing therapy, researchers at the Children’s Hospital of Philadelphia have reported success in treating an infant with a severe metabolic disorder. Kiran Musunuru, Barry J. Gertz Professor for Translational Research in the University of Pennsylvania’s Perelman School of Medicine, presented the case at the American Society of Gene and Cell Therapy’s 2025 annual meeting. The case study was simultaneously published in The New England Journal of Medicine.
Metabolic disorders such as argininosuccinic and glutaric aciduria, methylmalonic acidemia, homocystinuria or primary hyperoxaluria require specific diets to prevent the accumulation of substances that the body can’t process. Current treatments mainly focus on managing symptoms and metabolite levels, and do not always prevent the progressive deterioration caused by mutations associated with the condition. However, emerging gene therapies hold promise for transforming these diseases by targeting their underlying causes, as presented in the oral abstract session, “Gene and cell therapy for metabolic diseases” of the ongoing 28th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) meeting in New Orleans.
Mavrix Bio has received IND clearance from the FDA for MVX-220, an investigational AAV gene therapy for the treatment of Angelman syndrome. The company expects to initiate its first-in-human study, ASCEND-AS, in the second half of this year.
Capsida Biotherapeutics Inc. has gained IND clearance from the FDA for CAP-002, its first-in-class, intravenously administered gene therapy for syntaxin-binding protein 1 developmental and epileptic encephalopathy (STXBP1-DEE). Dosing in the phase I/IIa SYNRGY trial will begin in the third quarter of this year.
Following last fall’s $1 billion development deal with Eli Lilly and Co., precision medicine company Haya Therapeutics SA has raised $65 million in a series A. It’s all part of increased validation from big pharmas that long noncoding RNAs, such as those being developed by Haya, have a strong future.
Genprex Inc. and University of Pittsburgh have entered into a new sponsored research agreement (SRA) to study GPX-002, Genprex’s gene therapy for diabetes in animal models of type 1 and type 2 diabetes.
“I’m a pediatrician in metabolic diseases, and every day in my clinical work I’m confronted with our lack in effective therapies for our patients.” That was the sobering introduction by Sabine Fuchs in her talk at the 2025 Congress of the European Association for the Study of the Liver in Amsterdam this week. The nature of metabolic diseases makes it difficult to develop treatments for them. “There are over 1,500 diseases known by now, and it is just very difficult to develop therapies for each and every individual rare disease.”
