L-carnitine — a molecule often taken as an oral dietary supplement — boosts the efficacy of enzyme replacement therapy (ERT), increasing by four times the activity of acid alpha-glucosidase (GAA), the faulty enzyme in Pompe disease, in patient-derived cells, a study shows. The molecule was found to stabilize…

Antioxidants can increase the effectiveness of enzyme replacement therapy (ERT) for Pompe disease caused by oxidative stress, the damage in cells or tissues by reactive oxygen molecules, according to a study in cells and mice. The findings also showed that enhancing autophagy — the destruction of damaged or redundant…
Nexviazyme (avalglucosidase alfa), a next-generation enzyme replacement therapy, has been approved by Health Canada for people with late-onset Pompe disease ages 6 months and older. “The Health Canada approval of Nexviazyme is an important milestone for Canadian Pompe patients and may represent a new standard of care,” Mark…
Getting a six-and-a-half-hour enzyme replacement infusion once a week can be stressful. And I’m not even the one getting it. My son, Cayden, 3, gets an infusion called Lumizyme (alglucosidase alfa) to treat his infantile-onset Pompe disease. While the infusions have become routine for…
A new enzyme replacement therapy (ERT) targeting specific cell types boosts the delivery of acid alpha-glucosidase (GAA) — the enzyme missing or defective in Pompe disease patients — to muscle and heart cells, a study shows. Compared to standard ERT, the targeted approach by Regeneron Pharmaceuticals normalized the…
Starting treatment with enzyme-replacement therapy (ERT) in the first days of life appears to lessen the risk of hearing impairments in children with infantile-onset Pompe disease (IOPD), researchers report. “Our study may enhance awareness of early intervention before hearing-related morbidities can develop in patients with IOPD,” its researchers…
Newly approved Nexviazyme (avalglucosidase alfa) is a next-generation, alternative enzyme replacement therapy for late-onset Pompe disease patients starting at age 1. In clinical trials that supported the Aug. 6 approval by the U.S. Food and Drug Administration (FDA), meaningful improvements in respiratory muscle strength and mobility were evident in patients given…
The U.S. Food and Drug Administration (FDA) has approved Nexviazyme (avalglucosidase alfa), a next-generation enzyme replacement therapy for late-onset Pompe disease. The medication, administered by infusion into the bloodstream every two weeks, is approved for patients 1 year or older and is expected to be available in the…
A committee of the European Medicines Agency (EMA) has recommended the approval of avalglucosidase alfa, a next-generation enzyme replacement therapy (ERT) developed by Sanofi Genzyme, for people with Pompe disease. That recommendation, by the Committee for Medicinal Products for Human Use (CHMP), paves the way for marketing authorization to be granted by…
Walking distance improved in late-onset Pompe disease patients on enzyme replacement therapy (ERT), while their lung function and muscle strength remained unchanged, a meta-analysis has found. More studies are, however, needed to confirm these findings and “to obtain more…
