Enzyme replacement therapy (ERT) was effective in a newborn with infantile-onset Pompe disease (IOPD) who developed treatment antibodies and had low blood levels of a type of immune cell called neutrophils, according to a case report. Researchers stressed the importance of including Pompe disease in newborn screening programs…

Enzyme replacement therapy (ERT) given as early as possible may lead to better outcomes in children with classic infantile-onset Pompe disease (IOPD), according to a long-term study conducted in Taiwan. “Our study demonstrates that administering ERT as soon as feasible and employing short-term hydrocortisone premedication leads to better…

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…

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…

Adding L-alanine supplements to standard enzyme replacement therapy (ERT) for a young girl with Pompe disease led to improvements in several metabolic and body composition measures, a case report shows. According to researchers, this was the first known report of oral supplements of L-alanine — an amino acid,…

Macroglossia, or an abnormally enlarged tongue, caused difficulty swallowing, speech abnormalities, and reduced breathing during sleep for five people with late-onset Pompe disease (LOPD), according to a recent French study. Treatment with enzyme-replacement therapy (ERT), a standard of care for Pompe patients, did not alleviate the debilitating symptoms,…

A program of supervised resistance exercise can improve muscle function — including in muscles needed to breathe — for adults with late onset Pompe disease (LOPD), a small study suggests. “Our findings encourage use of supervised exercise and inspiratory muscle training for improving physical function and health to improve…

Interruptions to Myozyme enzyme replacement therapy (ERT) regimens during the COVID-19 pandemic led to worsened motor symptoms and poorer respiratory function in patients with Pompe disease, a French study found. These decreases in motor and respiratory function — seen after just a couple of months — were not…

Long-term treatment with Nexviazyme (avalglucosidase alfa) safely and effectively improves lung function and walking ability in children and adults with late-onset Pompe disease (LOPD), according to nearly two years of data from the Phase 3 COMET trial. These findings, along with positive long-term results from the Phase 2…

Long-term treatment with Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — results in variable but satisfactory motor and respiratory outcomes among older adults recently diagnosed with late-onset Pompe disease (LOPD), a study from Germany reported. According to its researchers, these findings were…
