Pombiliti (cipaglucosidase alfa), a component of AT-GAA, a two-part investigational therapy, has been approved to treat adults with late-onset Pompe disease (LOPD) in the European Union. The European Commission (EC) ruling comes on the heels of a positive opinion issued by the Committee for Medicinal Products for Human…

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…

Researchers created and characterized an infantile-onset Pompe disease (IOPD) mouse model that carried a genetic defect commonly found among people with Southern Han Chinese ancestry, a study reported. The model recapitulated most of the signs and symptoms of IOPD and, according to researchers, is ideal to evaluate potential IOPD…

An MRI-based study found that progression of white matter involvement in the brain among patients with infantile-onset Pompe disease (IOPD) occurred at different rates and correlated with cognitive decline — despite ongoing treatment. White matter abnormalities also were tied to elevated bloodstream levels of the neurofilament light chain (NfL)…

A newborn boy was diagnosed with both infantile-onset Pompe disease (IOPD) and sickle cell disease (SCD) in the first case study to report two co-existing genetic disorders. The boy was given enzyme replacement therapy (ERT), a standard Pompe treatment, and regular blood transfusions to prevent heart damage…

Stem cell-mediated gene therapy normalized glycogen build-up in muscle, heart, and brain tissue of a Pompe disease mouse model, a study shows. Treatments also restored cellular defects and motor impairment associated with the condition. The researchers recommended stem cell-based gene therapy as a candidate for future clinical development. The…

In an interview study, mothers of children who tested positive for Pompe disease in genetic newborn screening programs — and would be diagnosed with the late-onset type, or LOPD — expressed uncertainty about the age of symptom onset for their sons and daughters, and concerns about their child’s future.

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…

Adults with late-onset Pompe disease in the U.K reported a long and distressing diagnostic process, with most patients calling in interviews for a reduced time to diagnosis, a shorter wait for a specialist appointment, and an earlier treatment start, a study found. At diagnosis — which often came only…

Based on a literature and database analysis, the predicted genetic prevalence of disease-related variants in the GAA gene — the underlying cause of Pompe disease — is higher in the Korean population than in Japanese, a study indicates. The study, “Two Approaches for a Genetic Analysis…
