Infantile-onset Pompe disease (IOPD) patients who develop antibodies against enzyme replacement therapy (ERT) exhibit a distinct immune profile from those who don’t, according to recent research. Patients who developed these so-called high and sustained antibody titers, or HSAT, were skewed toward a type 2 immune profile, which the…

People with late-onset Pompe disease (LOPD) treated with Nexviazyme (avalglucosidase alfa) may be more than twice as likely to benefit from treatment than those on Lumizyme (alglucosidase alfa), a new analysis of data from the Phase 3 COMET trial suggests. The analysis employed a method called the…

More late-onset Pompe disease (LOPD) patients treated with Nexviazyme (avalglucosidase alfa) achieved clinically meaningful improvements in patient-reported outcome (PRO) measures related to symptoms, daily life impacts, and life quality than those treated with Lumizyme (alglucosidase alfa). That is according to new analyses from the COMET Phase 3 clinical…

A stem-cell based gene therapy that’s modified for better entry into muscle cells was seen to normalize protein levels in the skeletal muscle tissue of a mouse model of Pompe disease, according to a new report. The Pompe mice exhibited altered levels of hundreds of proteins — including ones…

Pombiliti (cipaglucosidase alfa) plus Opfolda (miglustat), a combination therapy formerly known as AT-GAA, has been approved by the U.S. Food and Drug Administration (FDA) to treat certain adults with late-onset Pompe disease (LOPD) who are not improving on their current enzyme replacement therapy (ERT). Its developer, Amicus…

Among children with classic infantile-onset Pompe disease (IOPD), enzyme replacement therapy (ERT) was associated with prolonged survival, but mortality rates remained high, according to a recent French study. In general, while mortality rates were high in the first three years of life, patients then stabilized on ERT for…

Treatment with AT-GAA, Amicus Therapeutics’ experimental two-part therapy for Pompe disease, has now been shown to improve motor function, and to stabilize or improve lung function, for up to four years in adults. That’s according to new analyses from the ongoing Amicus-sponsored Phase 1/2 ATB200-02 trial…

Cardiac function normalized within a year of starting enzyme replacement therapy (ERT) for children with classic infantile-onset Pompe disease (IOPD) and remained stable over about 10 years, a study found. The findings were confirmed with standard and more advanced techniques to look at cardiac function. In light of the…

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,…

Astellas Gene Therapies has obtained the rights to develop medication that could help reduce preexisting immune responses against the viral carrier used in ATA845, its investigational gene therapy for adults with late-onset Pompe disease (LOPD). Called IdeXork, or Xork, the investigational medication was developed by Selecta Biosciences,…
