Parents face significant anxiety and uncertainty after their newborn screens positive for a lysosomal storage disorder (LSD) like Pompe disease, but these emotions usually resolve over time once families receive clear, comprehensive information, a new study finds. However, researchers warn that this anxiety often persists in parents whose children…

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…

Switching to Nexviazyme (avalglucosidase alfa) was safe and effective in a 12-year-old boy with infantile-onset Pompe disease (IOPD) who developed a strong immune response against Lumizyme (alglucosidase alfa) that affected treatment efficacy. That’s according to a case study in South Korea, which supports the use of Nexviazyme…

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…

Orthodontic treatment successfully addressed speech and swallowing problems in a young girl with infantile-onset Pompe disease (IOPD), according to a case report from Italy. “The approach outlined in this paper serves as an illustrative example of orthodontic treatment for addressing speech and swallowing difficulties in patients with Pompe Disease,”…

A 43-year-old woman who was experiencing breathing problems and muscle weakness was eventually diagnosed with late-onset Pompe disease (LOPD) through genetic testing, highlighting the challenges of diagnosing the condition due to its rarity and nonspecific symptoms, according to a study. “It is important to consider late-onset Pompe disease in…

Researchers defined a threshold for improvements in lung function that adults with late-onset Pompe disease (LOPD) perceive as clinically meaningful when treated with enzyme replacement therapies. A study found that when thresholds were applied to data from the Phase 3 COMET study, more Pompe patients treated with the…

Switching from Lumizyme (alglucosidase alfa) to Pombiliti + Opfolda (cipaglucosidase alfa and miglustat) improved or stabilized motor function, muscle strength, and lung function in adults with late-onset Pompe disease (LOPD). That’s according to a new analysis from the Phase 3 PROPEL trial (NCT03729362) that also showed…
