A middle-aged woman with late-onset Pompe disease (LOPD) developed damage to her sensory nerve cells after receiving the gene therapy candidate AT845 — in development as a Pompe disease treatment — in a clinical trial, according to a new case report. While the woman’s symptoms, particularly reduced sensations…

The first patient has been dosed in a Phase 1/2 clinical trial testing AB-1009, Askbio’s investigational gene therapy for late-onset Pompe disease (LOPD), the company said. The trial, PROGRESS-GT LOPD (NCT07282847), primarily aims to assess the therapy’s safety in up to 12 adults with LOPD, aged 18 and…
A single dose of a specialized gene therapy has successfully normalized muscle function for more than a year in a mouse model of Pompe disease. By using “data-mined” genetic sequences designed to supercharge enzyme production specifically in muscle cells, researchers achieved protein levels up to 30 times higher than…
The U.S. Food and Drug Administration (FDA) has cleared AskBio’s investigational new drug application for AB-1009, a potential one-time gene therapy being developed for late-onset Pompe disease (LOPD). The clearance enables the therapy to proceed to a Phase 1/2 clinical trial (NCT07282847)…
A viral vector engineered from a duck virus, called AAV.div3A, may offer a way to safely give patients more than one dose of gene therapyaccording to a study. This is something that is largely impossible today, yet critical for diseases requiring early treatment and that may need additional doses over…
The activity levels of Myozyme (alglucosidase alfa) measured in blood and white blood cells may help indicate how well gene therapies are working in people with classic infantile Pompe disease who are receiving enzyme replacement therapy (ERT). That’s according to a study that analyzed the pharmacokinetics of…
An experimental gene therapy known as GC301 improved motor function and cardiac outcomes for three out of four infants with infantile-onset Pompe disease (IOPD) in a small clinical trial. The treatment was also well tolerated. One year after treatment, these three participants had reached milestones such as…
Gene and enzyme replacement therapies for Pompe disease improved breathing and limb strength in a mouse model of the disease, a study showed. The researchers said the improvement was associated with glycogen clearance in the tongue, the lungs, and the diaphragm, the main muscle involved in respiratory control. Glycogen…
A genomic medicine designed to correct the genetic defect found in up to 90% of people with late-onset Pompe disease (LOPD) worked as intended in patient-derived muscle cells and a mouse model, according to a study. The study, “Splicing correction by peptide-conjugated morpholinos as a novel…
A therapeutic approach designed to correct the cellular defect caused by a common mutation in people with late-onset Pompe disease (LOPD) worked as intended to increase activity of the acid alpha glucosidase (GAA) enzyme in lab studies, according to a study. People with Pompe disease are lacking in…
