enzyme replacement therapy

A baby boy with infantile-onset Pompe disease and a severely enlarged heart was treated early with Nexviazyme (avalglucosidase alfa), a next-generation enzyme replacement therapy from Sanofi, leading to rapid and sustained improvement of heart function, according to a case report from Japan. “These findings may support the…

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.

I still remember the phone call as if it were frozen in time. It was mid-morning, and I was in bed feeding my newborn, Caroline. With the shades slightly drawn, just a sliver of light crept in, letting us both cozy up and drift off. Caroline was only a week…

A new noninvasive imaging tool called quantitative muscle ultrasound, or QMUS, can detect progressive muscle disease in people with infantile-onset Pompe disease (IOPD) who are on enzyme replacement therapy (ERT), according to a small study by U.S. researchers. The study found that QMUS correlated with functional status and…

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…

I remember the day my 6-year-old son, Cayden, was diagnosed with infantile-onset Pompe disease like it was yesterday. Hearing the news broke me, and I was scared half to death. I had no idea what to expect, and searching the internet didn’t help because I came across a…

Dyne Therapeutics has unveiled promising preclinical data for its enzyme replacement therapy (ERT) FORCE-GAA — part of the company’s propriety FORCE platform — designed to treat Pompe disease. The novel therapy has demonstrated the potential to deliver the treatment directly to skeletal and heart muscles, as well…

Note: This column describes the author’s son’s experiences with Nexviazyme and Lumizyme. Not everyone will have the same response to treatment. Consult your doctor before starting or stopping a therapy or changing its dose. My 6-year-old son, Cayden, has received infusions of enzyme replacement therapy for the entirety…

Switching to Nexviadyme (avalglucosidase alfa) from Myozyme (alglucosidase alfa) can help to halt the worsening of motor function in adults with late-onset Pompe disease (LOPD), according to a recent study in France. However, no significant differences in lung function were reported after patients switched these enzyme…
