Nearly three years of treatment with Nexviazyme (avalglucosidase alfa) led to long-term improvements in walking ability and lung function for people with late-onset Pompe disease (LOPD), according to new data from the Phase 3 clinical trial COMET. …

Three siblings with Pompe disease caused by the same mutations were described in a recent report. Despite all having the same disease-causing mutations, the clinical presentation of the three children differed dramatically — one began showing symptoms in infancy, while another had not shown clinical abnormalities at the age…
Single and multiple ascending doses of MZE001, Maze Therapeutics‘ experimental oral substrate reduction treatment for Pompe disease, were well tolerated and reduced glycogen levels in healthy volunteers in a Phase 1 trial, data show. These findings support a Phase 2 trial of MZE001 in people with Pompe disease,…
Regulatory authorities in the U.S. and the U.K. are expected to decide in the third quarter of this year whether or not to approve AT-GAA as a treatment for late-onset Pompe disease, according to its developer, Amicus Therapeutics. The U.S. Food and Drug Administration (FDA) had previously…
Late-onset Pompe disease (LOPD) patients exhibit significant gene activity changes in their skeletal muscles compared with healthy people, some of which were normalized after six months of Nexviazyme (avalglucosidase alfa) treatment, a study found. Pathways involved in lysosome function, energy metabolism, and inflammation appeared to be most altered,…
Anaphylaxis, a severe allergic reaction, occurred in nearly one-third of children with Pompe disease treated with the enzyme replacement therapy Myozyme (alglucosidase alfa) in a small study. However, rapid desensitization regimens — using small doses initially and then increasing the doses — safely re-established tolerance to Myozyme in…
Nexviadyme, (avalglucosidase alfa), Sanofi’s next-generation enzyme replacement therapy for Pompe disease, will now be available in the U.K. through the National Health Service (NHS). That’s according to a review from the National Institute for Health and Care Excellence that deemed Nexviadyme as an option for treating people —…
Researchers in Taiwan have developed new molecules that can stabilize the acid alpha-glucosidase (GAA) enzyme, a strategy they say might improve the effectiveness of treatments for Pompe disease. Their study, “Harnessing polyhydroxylated pyrrolidines as a stabilizer of acid alpha-glucosidase (GAA) to enhance the efficacy of enzyme…
FORTIS, a Phase 1/2 clinical trial of an experimental gene therapy called AT845, is due to restart in adults with late-onset Pompe disease (LOPD), thanks to a decision by the U.S. Food and Drug Administration (FDA). The trial was put on hold mid-2022 after one of its…
Researchers created and characterized an infantile-onset Pompe disease (IOPD) mouse model that carried a genetic defect commonly found among people with Southern Han Chinese ancestry, a study reported. The model recapitulated most of the signs and symptoms of IOPD and, according to researchers, is ideal to evaluate potential IOPD…
