NGGT (Suzhou) Biotechnology Co. Ltd. has presented preclinical data on an AAV vector approach that expresses human PAH, rAAV8-PAH, also known as NGGT-002. NGGT-002 has liver tropism and it was codon-optimized for expressing PAH in the liver.
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.
The U.K. Medicines and Healthcare Products Regulatory Agency (MHRA) and the Gene Therapy Advisory Committee (GTAC) have approved a clinical trial application (CTA) submitted by University College London (UCL) to initiate a phase I/II trial of BGT-OTCD, Bloomsbury Genetic Therapies Ltd.’s liver-targeted AAV-LK03 gene therapy, in pediatric patients with ornithine transcarbamylase deficiency (OTCD).
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.
