enzyme replacement therapy

Patients with late-onset Pompe disease (LOPD) should be followed regularly and start on enzyme replacement therapy (ERT) if they develop symptoms, according to an analysis of available guidelines. The study, “Comparison of recent pivotal recommendations for the diagnosis and treatment of late-onset Pompe disease using…

Amicus Therapeutics received two U.S. patents for ATB200, a unique recombinant (lab-made) human acid alpha-glucosidase (rhGAA) enzyme, and the biologic component of the company’s investigational Pompe disease therapy AT-GAA. One patent covers the composition of matter for rhGAA; the second, the methods for making ATB200. The patents expire in 2035…

A research team in Korea has developed a new method using rice to produce lab-made human acid alpha-glucosidase (GAA) for the treatment of Pompe disease. Their findings were published in the study, “N-glycan Remodeling Using Mannosidase Inhibitors to Increase High-mannose Glycans on Acid α-Glucosidase in Transgenic Rice…

Early treatment with a four times higher dose of Myozyme (alglucosidase alpha) was safe and enabled normal motor development and normalization of markers of muscle damage and disease progression in a boy with classic infantile-onset Pompe disease, according to a study. The study, “Early…

Long-term interruption of enzyme replacement therapy (ERT) can lead to negative outcomes for late-onset Pompe disease patients, affecting their lung and exercise capacity as well as quality of life, a Swiss retrospective study shows. However, for most patients, resuming ERT can help restore the key clinical parameters that deteriorated during the pause…

Low-dose treatment with methotrexate can reduce the immune reaction that often accompanies enzyme replacement therapies in infants with Pompe disease, researchers report. Their study, “An immune tolerance approach using transient low-dose methotrexate in the ERT-naïve setting of patients treated with a therapeutic protein: experience in infantile-onset Pompe…

Amicus Therapeutics is planning to launch a pivotal trial to compare its investigational therapy AT-GAA (ATB200/AT221) to the current standard of care available for patients with Pompe disease. The new trial is expected to provide additional clinical data to support Accelerated Approval for AT-GAA by the U.S.

Clenbuterol as an add-on therapy appears to be safe and significantly improves the effectiveness of enzyme replacement therapy (ERT) in patients with late-onset Pompe disease, according to the results from a Phase 1/2 trial. The study, “Correction of Biochemical Abnormalities and Improved Muscle Function in a Phase…

Adding immunomodulatory medicines to enzyme replacement therapy (ERT) — Myozyme (alglucosidase alfa) — gives temporary but not long-term protection from antibodies that can block ERT’s effectiveness in patients with classic infantile Pompe disease. Better immunomodulatory regimens are needed to induce long-term…

Treatment with enzyme replacement therapy can help children with classic infantile Pompe disease reach adulthood. However, it fails to prevent the long-term effects of the disease in the brain and consequent   development of intellectual disabilities, a study shows. The study titled “Classic infantile Pompe patients…
