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…
enzyme replacement therapy
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…
Long-term use of Myozyme (alglucosidase alfa), marketed as Lumizyme in the U.S., helped individuals with late-onset Pompe disease (LOPD) maintain their ability to walk and breathe, while remaining generally safe and well tolerated over 15 years, according to a study in Italy. While responses varied, fewer than expected…
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…
Gene and enzyme replacement therapies for Pompe disease improved breathing and limb strength in a mouse model of the disease, a study showed. The researchers said the improvement was associated with glycogen clearance in the tongue, the lungs, and the diaphragm, the main muscle involved in respiratory control. Glycogen…
A desensitization protocol allowed doctors to successfully treat an infant with classic infantile-onset Pompe disease (IOPD) who developed an allergic reaction to Myozyme (alglucosidase alfa), according to a report. The protocol, which was also used when the patient switched to Nexviadyme (avalglucosidase alfa), involved delivering the Pompe…
Children with infantile-onset Pompe disease (IOPD) experienced reductions in disease-related biomarkers and stabilizations or improvements in clinical function after switching from Myozyme (alglucosidase alfa) — sold as Lumizyme in the U.S. — to Nexviazyme (avalglucosidase alfa), according to a new study from Taiwan. These functional improvements were…
The combination therapy Pombiliti + Opfolda (cipaglucosidase alfa/miglustat)Â may help overcome some of the limitations of standard enzyme replacement therapies (ERT) for treating late-onset Pompe disease (LOPD), according to a recent presentation. Like other ERTs, Pombiliti + Opfolda contains a lab-made version of the enzyme that LOPD patients…
Higher-than-approved doses of enzyme replacement therapy, or ERT, normalized several features of infantile-onset Pompe disease (IOPD), including motor and heart function, in the first patient enrolled in a pilot study. The patient began high-dose ERT as a newborn, and eventually met all developmental milestones by age 7. With…
