At the recent ASGCT meeting, researchers from Exegenesis Bio Inc. presented preclinical data for EXG-102-031, a novel recombinant adeno-associated virus (rAAV)-gene therapy being developed for the treatment of neovascular age-related macular degeneration (AMD), also called wet AMD (wAMD).

Gene therapy technology makes it possible to select diseased or mutated cells from a patient, modify them in the laboratory and reintroduce them to the body to treat different disorders. This is known as ex vivo autologous gene therapy. The difference with allogeneic cell techniques is whether the donor is oneself (autologous) or a compatible person (allogeneic), which would provide healthy cells that do not need genetic modification.

Sania Therapeutics Inc. is setting out its stall at the American Society of Gene & Cell Therapy (ASGCT) conference in Los Angeles this week, after generating proof of concept for its chemogenetics approach to treating motor disorders. The company has engineered adeno-associated viral vectors that can be targeted to specific cell types. It will use these to deliver well-characterized ion channels to dysfunctional motor neurons.

The discovery of DNA was a milestone in the history of science that led to a breakthrough in biomedical research. By associating disease and genetics, genome correction techniques were ultimately developed that are supposed to work in the same way that antibiotics and antivirals block pathogenic microorganisms: by directly attacking the causes of disease.

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.
