A therapeutic approach designed to correct the cellular defect caused by a common mutation in people with late-onset Pompe disease (LOPD) worked as intended to increase activity of the acid alpha glucosidase (GAA) enzyme in lab studies, according to a study. People with Pompe disease are lacking in…
Note: This story has been updated March 6, 2025, to correct a quote from Mindy Henderson, MDA vice president of disability outreach and empowerment. The Muscular Dystrophy Association (MDA) is once again hosting its annual gathering, the MDA Clinical & Scientific Conference. The 2025 event will take place…
Several cellular processes, particularly those related to lysosome function and autophagy, are altered in the muscles of people with late-onset Pompe disease (LOPD), and supplementation with an amino acid as a regulator could be a “promising therapeutic approach,” according to a study. Levels of L-arginine, an amino acid that…
Combining a symptom-based scoring tool with healthcare provider education may help identify patients who have an increased risk of having a missed diagnosis of late-onset Pompe disease (LOPD), a study in the U.S. shows. A LOPD diagnosis should be considered in patients with progressive muscle weakness and at least…
The benefits seen with Nexviazyme (avalglucosidase alfa) treatment in three people in Japan with Pompe disease matched those found among the overall patient population of two global clinical trials, a new case series analysis by researchers in that country has found. This trio of Japanese patients — two…
The U.S. Food and Drug Administration (FDA) has cleared Aro Biotherapeutics to conduct a Phase 1 clinical trial to test ABX1100, its experimental substrate reduction therapy, in people with late-onset Pompe disease (LOPD). The clearance of Aro’s investigational new drug (IND) application comes as the company is…
Young patients with late-onset Pompe disease (LOPD) who do not yet show disease symptoms should be regularly monitored for timely identification of symptoms so that treatment can be started early, a study suggested. Current diagnostic procedures enable early diagnosis of LOPD even in pre-symptomatic stages, said the researchers, who…
Many adults with late-onset Pompe disease (LOPD) see their own health status as declining over time, with difficulty swallowing and speaking, and scoliosis (sideways curvature of the spine) being burdensome symptoms for those on enzyme replacement treatment (ERT) for more than 15 years, a survey study has found.
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…
Scientists at Sanofi created digital counterparts of people with Pompe disease to support drug development and advance Pompe disease treatment. In a simulated clinical trial of digital twins with infantile-onset Pompe disease (IOPD), Sanofi’s Nexviazyme (avalglucosidase alfa), an enzyme replacement therapy, outperformed its first-generation Lumizyme (alglucosidase alfa)…
