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…

Throughout 2025, the team at Pompe Disease News has brought readers updates on emerging treatments, scientific advances, and clinical findings in Pompe disease. Here is a list of the top 5 most-read news stories of this year. We are grateful to have had the opportunity to support people…

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…

Pompe disease patients bear a substantial burden from coexisting conditions and the ongoing need for supportive care, despite treatment with enzyme replacement therapy (ERT), a real-world study in the U.S. found. Researchers also found a relatively high rate of ERT discontinuation, particularly among people with late-onset Pompe…

The buildup of the complex sugar glycogen, the main cause of muscle damage in late-onset Pompe disease (LOPD), can be detected in people with the condition long before visible symptoms appear, researchers in Denmark found. Using an advanced imaging technique capable of measuring glycogen inside muscles —a test that…

A new noninvasive imaging tool called quantitative muscle ultrasound, or QMUS, can detect progressive muscle disease in people with infantile-onset Pompe disease (IOPD) who are on enzyme replacement therapy (ERT), according to a small study by U.S. researchers. The study found that QMUS correlated with functional status and…

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…

Wearable digital health technologies (DHTs) may help identify subtle walking and movement impairments in people with late-onset Pompe disease (LOPD) that are not evident in standard clinical evaluation, a recent study in Italy shows. These technologies “may have important implications for management, follow-up, and treatment decisions in clinical practice,”…

Scientists at Sanofi have developed a new type of enzyme replacement therapy (ERT) that can clear excess glycogen — the underlying cause of Pompe disease — from the cells in the brain and spinal cord, which are untouched by current ERTs. That’s according to a mouse…

Locations where antibodies bind to enzyme replacement therapy (ERT) and potentially reduce its effectiveness in treating Pompe disease can now be identified using a drop of blood, a study reports. Knowing where anti-ERT antibodies bind may help find interventions to diminish the immune responses that generate them and also…
