Amplo Biotechnology Inc. has been awarded a fast track phase I/II Small Business Technology Transfer (STTR) grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) of the National Institutes of Health (NIH) to fund further development of AMP-201, an AAV-ColQ gene therapy designed to address congenital myasthenic syndrome caused by collagen Q (ColQ) deficiency.

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.

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.

Rocket Pharmaceuticals Inc. has received IND clearance from the FDA for RP-A601, an AAV.rh74-based gene therapy candidate for the treatment of arrhythmogenic cardiomyopathy due to plakophilin 2 pathogenic variants (PKP2-ACM). RP-A601 offers the potential for a one-time, curative alternative to medical therapy, implantable cardioverter defibrillators and ablations.

A proof of concept of ex vivo genetic modification of cells from patients and their transplantation in mice has demonstrated, for the first time, the therapeutic possibilities of prime editing in sickle cell disease (SCD).
