enzyme replacement therapy

While most adults on Myozyme (alglucosidase alfa) for late-onset Pompe disease develop antibodies to the replacement enzyme, these usually do not limit efficacy; however, high and sustained levels of neutralizing antibodies are linked to more infusion-associated reactions and may lead some patients to stop therapy, a study found. The…

When my daughter Caroline was diagnosed with late-onset Pompe disease as a baby, we started enzyme replacement therapy before her first birthday. I remember spending what felt like endless hours at our children’s hospital, meeting new doctors and nurses, going through test after test. At first, it was…

Newborn screening is uncovering signs of Pompe disease in infants months or even years before obvious symptoms appear, allowing for early treatment that can normalize markers of muscle damage, according to new research. A study tracking seven children with late-onset Pompe disease (LOPD) found that starting enzyme…

Children with infantile-onset Pompe disease (IOPD) who start enzyme replacement therapy (ERT) within the first month of life have healthier hearts than those who start the treatment later, a study found. “Our findings support the benefit of early ERT initiation in IOPD, particularly for cardiac outcomes,” the researchers…

Women with late-onset Pompe disease (LOPD) can safely use enzyme replacement therapy (ERT) during pregnancy and breastfeeding, according to a case series. Of the five reported pregnancies from three women, all were uneventful, and all five children breastfed by mothers receiving ERT exhibited normal growth and age-appropriate development.

In the first study of its kind, U.S. researchers showed that focused ultrasound (FUS) could be used to allow approved enzyme replacement therapies (ERTs) — which can not get past the brain’s protective barrier in humans — to enter the brain of a mouse model of Pompe disease.

Pompe disease patients bear a substantial burden from coexisting conditions and the ongoing need for supportive care, despite treatment with enzyme replacement therapy (ERT), a real-world study in the U.S. found. Researchers also found a relatively high rate of ERT discontinuation, particularly among people with late-onset Pompe…

Switching from Lumizyme (alglucosidase alfa) to Nexviazyme (avalglucosidase alfa) stabilizes or improves lung function in people with late-onset Pompe disease (LOPD). That’s according to new analyses from the COMET Phase 3 clinical trial and its open-label extension study, which showed the benefits of switching to Nexviazyme were…

Scientists at Sanofi have developed a new type of enzyme replacement therapy (ERT) that can clear excess glycogen — the underlying cause of Pompe disease — from the cells in the brain and spinal cord, which are untouched by current ERTs. That’s according to a mouse…

Locations where antibodies bind to enzyme replacement therapy (ERT) and potentially reduce its effectiveness in treating Pompe disease can now be identified using a drop of blood, a study reports. Knowing where anti-ERT antibodies bind may help find interventions to diminish the immune responses that generate them and also…
