late-onset Pompe disease

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.

I remember the day vividly. It was an overcast morning on Saturday, Nov. 17, 2018. My wife and I hopped in the car and headed north toward Marina del Rey, California, giving me an hour to contemplate all the thoughts racing through my mind. A few months earlier, my neurologist…

The U.S. Food and Drug Administration (FDA) has granted orphan drug designation to MZE001, Maze Therapeutics‘ investigational oral treatment for Pompe disease. “Pompe disease is a serious and often fatal disorder, and MZE001 has the potential to offer patients an oral, disease-modifying option that improves clinical outcomes and…

I can remember my 4-year-old son’s first surgery like it was yesterday. Cayden was just shy of 2 months old when I watched the anesthesia team wheel away my tiny baby. It was the first of many surgeries for him, but also one of the hardest. We opted to…

A woman was diagnosed with advanced late-onset Pompe disease after three decades of being misdiagnosed, according to a recent case report. After diagnosis, the woman began treatment with Myozyme (alglucosidase alfa), which led to marked improvements that enabled her to live independently. The findings underscore a need for…

A report describes the unusual case of a man with late-onset Pompe disease (LOPD) that manifested with abnormalities in blood flow in the brain causing stroke-like symptoms. Abnormalities affecting blood vessels in the brain may be an under-recognized complication of LOPD, the researchers said. The study, “…

Recently, my 4-year-old son, Cayden, made the long-awaited change to Nexviazyme (avalglucosidase alfa) infusions, a new treatment option for Pompe disease. We have wanted to switch treatments for a while, but faced some insurance challenges that caused a delay. Nevertheless, we finally managed to get him switched, and…

A small study in the U.K. is evaluating a noninvasive MRI-based tool that could potentially detect late-onset Pompe disease (LOPD) without the need for invasive muscle biopsies. This specialized muscle MRI also would monitor glycogen buildup — a hallmark of the condition — in muscles over time. The…

The U.S. Food and Drug Administration (FDA) has placed a clinical hold on the FORTIS Phase 1/2 trial of AT845, a single-dose gene therapy for adults with late-onset Pompe disease (LOPD). The decision was due to a study participant developing peripheral sensory neuropathy — nerve damage outside the brain…

The European Commission has approved the next-generation enzyme replacement therapy Nexviadyme (avalglucosidase alfa) to treat both late-onset and infantile-onset Pompe disease. This is the first time a new treatment for Pompe has been approved in Europe since 2006, according to Nexviadyme’s developer Sanofi Genzyme. “For more than…
