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 1-year-old boy with infantile-onset Pompe disease (IOPD) showed improved muscle strength and signs of less heart inflammation four months after receiving gene therapy, according to a case report. The findings in this case were confirmed with cardiac MRI, a noninvasive test that uses radio waves and magnets to…
A gene therapy designed to travel into muscles resulted in widespread production of the enzyme that’s missing or faulty in Pompe disease, according to a study that also describes a new rat model of the infantile-onset form of the disease. Researchers also observed that rats given a single…
Throughout 2023, Pompe Disease News brought you coverage of the latest developments in research into Pompe disease and clinical trials of potential new treatments. Here is a list of the 10 most-read stories we published across that year. We hope to continue being a source of information…
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…
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…
