Recently, my 4-year-old son, Cayden, had an appointment with his metabolic specialist. This doctor manages everything related to his Pompe disease and is part of a team of doctors that diagnosed him when he was just 1 month old. They also oversee everything related to his enzyme replacement infusions.

Most children with Pompe disease in a small study developed antibodies against the enzyme replacement therapy Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — but their presence did not limit treatment efficacy, its researchers reported. Children with the highest levels of antibodies also experienced most of…
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 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…
Patients with classic infantile-onset Pompe disease could benefit from increased dosing of Myozyme (alglucosidase alfa), an enzyme replacement therapy (ERT) marketed as Lumizyme in the U.S., according to a real-world European study. Benefits were seen in improved survival and ability to walk. “On the basis of our results,…
Gene therapy given with chaperones — specific molecules known to stabilize the structure of proteins — was found to enhance the availability of acid alpha-glucosidase, known as GAA, the missing or defective enzyme in Pompe disease (PD), in a mouse model. The treatment subsequently eased disease symptoms, with the…
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…
