A simple, noninvasive breathing intervention that briefly exposes the body to repeated bouts of low oxygen modestly improved breathing in a mouse model of Pompe disease, a study showed. Therapeutic acute intermittent hypoxia (tAIH) led to small but measurable increases in breathing rate, breath size, or the amount of…

GlycoNOE, a non-invasive form of MRI, detected glycogen accumulation in the muscles of a Pompe disease mouse model, demonstrating its potential as a noninvasive tool to directly assess disease severity and treatment response in patients, according to a study. The approach “holds great potential to facilitate pre-clinical and clinical studies…
Dyne Therapeutics has unveiled promising preclinical data for its enzyme replacement therapy (ERT) FORCE-GAA — part of the company’s propriety FORCE platform — designed to treat Pompe disease. The novel therapy has demonstrated the potential to deliver the treatment directly to skeletal and heart muscles, as well…
A powerful imaging technique called high-resolution intravital microscopy, or IVM, may be a useful tool for visualizing and quantifying the effectiveness of investigational treatments in mouse models of Pompe disease, according to recent research. The approach allows for cellular changes in muscles to be visualized in live animals. Using…
A stem-cell based gene therapy that’s modified for better entry into muscle cells was seen to normalize protein levels in the skeletal muscle tissue of a mouse model of Pompe disease, according to a new report. The Pompe mice exhibited altered levels of hundreds of proteins — including ones…
A new gene therapy for Pompe disease showed promise in a mouse model, researchers say, fully clearing in muscles the buildup of glycogen that characterizes the genetic disorder and also reducing it nearly completely in the brain. Glycogen is the stored form of glucose, or sugar — the body’s…
A diet combining an oral ketone precursor — a molecule being studied as a dietary supplement — and a cocktail of natural antioxidant molecules boosts the efficacy of enzyme replacement therapy (ERT) at maintaining muscle strength and motor function in a mouse model of Pompe disease, a study…
Certain protein modifications may enhance the ability of a therapeutically-delivered acid alpha-glucosidase (GAA) enzyme to be secreted and taken up by neighboring cells in models of Pompe disease, a study suggested. Such approaches could offer ways to improve the effectiveness of gene therapies for Pompe, although more work is…
Administrating a stem cell gene therapy before beginning enzyme-replacement therapy (ERT) prevented the development of antibodies against the acid alpha-glucosidase (GAA) enzyme, improved survival, and enhanced therapeutic benefits in a mouse model of Pompe disease, a recent study found. “Together, this study indicates that [stem cell] gene therapy induces…
AVR-RD-03, Avrobio‘s experimental blood stem cell gene therapy for classic infantile-onset Pompe disease, was found to be safe and effective in a mouse model of the disease. The findings, presented as a poster at the 2022 annual meeting of the American Society of Gene & Cell Therapy (ASGCT)…
