ERT

Two girls in Colombia with early-onset Pompe disease saw their symptoms improve after methotrexate treatment reduced the levels of antibodies they had developed against enzyme replacement therapy (ERT), according to a case report. ERT antibodies can cause the therapy to stop working. Methotrexate, a chemotherapy, can work as an…

A group of experts in Europe published updated recommendations for late-onset Pompe disease (LOPD) treatment, including for the first time guidance about switching between different approved treatments. The recommendations were published in the European Journal of Neurology in a paper titled, “Start, switch and stop (triple-S)…

An immune system modulatory regimen effectively reduced levels of antibodies against Myozyme (alglucosidase alfa), an enzyme replacement therapy (ERT) for Pompe disease, in patients with low levels of acid alpha-glucosidase (GAA) enzyme. That’s according to data from a Phase 4 study (NCT02525172), which assessed such a regimen…

Most people with classic infantile-onset Pompe disease (IOPD) develop brain abnormalities despite treatment with Myozyme (alglucosidase alfa), and these abnormalities are associated with poorer results on cognitive tests. That’s according to a study, “Long term survival in patients with classic infantile Pompe disease reveals a…

Early treatment with at least two cycles of bortezomib may help lower the levels of antibodies that can make enzyme replacement therapy (ERT) less effective, according to a report of two young children with infantile-onset Pompe disease. The cases add to earlier reports that bortezomib, an injectable medication…

The COVID-19 pandemic affected the treatment, as well as the physical and mental health, of people with Pompe disease, according to a recent survey of patients in 25 countries. More than 50% of respondents reported interruptions in enzyme replacement therapy (ERT) and physical therapy, affecting their disease, and…

Enzyme replacement therapy (ERT) for Pompe disease can be safely implemented at home, according to a study in the Netherlands. “Insights from this study can be used as a base for implementing home-based ERT in other countries and to further optimize patient care,” researchers wrote. The study, “Home-based…

Anaphylaxis, a severe allergic reaction, occurred in nearly one-third of children with Pompe disease treated with the enzyme replacement therapy Myozyme (alglucosidase alfa) in a small study. However, rapid desensitization regimens — using small doses initially and then increasing the doses — safely re-established tolerance to Myozyme in…

Nexviadyme, (avalglucosidase alfa), Sanofi’s next-generation enzyme replacement therapy for Pompe disease, will now be available in the U.K. through the National Health Service (NHS). That’s according to a review from the National Institute for Health and Care Excellence that deemed Nexviadyme as an option for treating people —…

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…
