Spinal muscular atrophy (SMA) is caused by mutations in the SMN1 gene, which encodes survival motor neuron 1, leading to reduced protein expression levels and degeneration of motor neurons in the spinal cord, with the consequent muscle atrophy. There is thus a need for new AAV gene therapies for SMA that confer better safety and efficacy.

Researchers from Skyline Therapeutics (Shanghai) Co. Ltd. presented preclinical data for the new recombinant AAV vector therapeutic SKG-0106, being developed for the treatment of neovascular (wet) age-related macular degeneration (AMD).

Fabry disease is a metabolic disease characterized by a deficiency in the lysosomal α-galactosidase enzyme caused by mutations in the GLA gene. This leads to substrate accumulation in the lysosomes, cellular dysfunction and organ damage.

In its bid to become, as Chairman and CEO David Hallal said, the “world’s most indispensable cell and gene therapy technology company,” Elevatebio LLC disclosed a $401 million series D round with support from new and existing investors. At the same time, the company’s Life Edit Therapeutics Inc. affiliate inked a potential billion-dollar collaboration focused on gene editing therapies.

LMU Klinikum recently presented data from studies of an intravitreal gene therapy for CNGA1-linked retinitis pigmentosa (CNGA1-RP).

One of the challenges in designing genetic and cellular strategies is getting the therapy to the right place. This is even more complicated when it comes to the nervous system. The brain is a complex organ that contains the most differentiated and inaccessible cells in human biology. It is an impassable safe, protected by the blood-brain barrier.

The most ambitious objective of any treatment is to eradicate the disease, acting on its origin to cure it instead of treating its symptoms. This is the purpose of the gene therapy against type 2 diabetes (T2D) and obesity that Fractyl Health Inc. is developing. Scientists from the Lexington, Mass.-based company have designed a strategy based on glucagon-like peptide-1 (GLP-1) to transform pancreatic cells and reverse the disease.
