acid alpha-glucosidase

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…

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…

Lumizyme (alglucosidase alfa) is an enzyme replacement infusion therapy by Sanofi Genzyme for people with Pompe disease. In the European Union, it is available under the brand name Myozyme. Here are answers to some frequently asked questions about this treatment. How does Lumizyme work? Lumizyme works to replace…

A small molecule called 3-BrPA was able to lower levels of glycogen — a complex sugar that builds up to toxic levels in Pompe disease — and ameliorate muscle and heart structural defects in a new zebrafish model of the genetic disorder, a recent study has shown.

A molecular “tag” to improve distribution of the acid-alpha glucosidase (GAA) protein within cells enhanced the efficacy of gene therapy in a mouse model of Pompe disease, a recent study suggests. The study, titled “AAV Gene Therapy Utilizing Glycosylation-Independent Lysosomal Targeting Tagged GAA in the…

Long-term enzyme replacement therapy (ERT) to treat people with Pompe disease loses effectiveness in maintaining walking ability, muscle strength, and lung function, a new study shows. Despite these results, ERT improved lung function when compared to the predicted outcome without ERT, and some patients responded…
