Epigenetic silencing could prevent the production of proteins that cause pathologies. CHARM (coupled histone tail for autoinhibition release of methyltransferase), a DNA methylation-based editor, suppressed transcription of prion proteins in the brains of mice.

As the hunt goes on for a better treatment in wet age-related macular degeneration (AMD), landmark analyses of two batches of phase II gene therapy data billed as positive were disclosed during the American Society of Retina Specialists annual meeting in Stockholm, where 4D Molecular Therapeutics Inc. and Adverum Biotechnologies Inc. offered findings.

The industry is looking, with renewed hope, to the “promise” of messenger RNA (mRNA) therapeutics for a wide range of diseases beyond COVID-19, and not only in vaccine form but also for gene and cell therapies.

In denying Medicaid patients with sickle cell disease or transfusion-dependent beta-thalassemia access to Vertex Pharmaceuticals Inc.’s fertility preservation program, which is intended to counteract a side effect of the company’s gene-editing therapy, Casgevy, “the federal government now stands as the barrier between thousands of predominantly Black Americans and the necessary medical care that would protect their basic right to have biological children,” Vertex said in a lawsuit filed July 15.

Orum Therapeutics Inc. struck a potential $945 million (₩1.3 trillion) deal with Vertex Pharmaceuticals Inc. to discover novel degrader antibody conjugates (DAC) as targeted conditioning agents for use with gene editing, including Vertex’s gene therapy, Casgevy (exagamglogene autotemcel).

Interim data from two early stage Friedreich’s ataxia (FA) cardiomyopathy studies from Lexeo Therapeutics Inc. hit the mark by reducing heart muscle thickness, a key cause of death among patients with the rare disease. The results came from the Sunrise-FA phase I/II study and an investigator-initiated phase Ia study of LX-2006, an adeno-associated virus-mediated gene therapy encoding the human frataxin gene. The drug is designed to improve frataxin protein expression to improve mitochondrial cell function.

Rznomics Inc. has received clinical trial notification (CTN) from Australia’s Therapeutic Goods Administration (TGA) for the initiation of a phase I/IIa trial evaluating RZ-004, a gene therapeutic candidate for autosomal dominant retinitis pigmentosa with rhodopsin mutation.

Patients with congenital hearing loss could benefit from a gene therapy currently in development. Although there are approaches that could reverse the process in children and young people before it becomes severe, so far, adults do not have any treatment that prevents the progressive deterioration of auditory sensory cells caused by this disease.
