Quantitative MRI (qMRI) imaging of the muscles is a useful technique for identifying signs of compromised muscle health in people with neuromuscular conditions like Pompe disease, according to a small study. The study identified specific patterns of qMRI changes in the thigh muscles of people with late-onset Pompe…

Dysfunction of the phrenic nerve, which is important for controlling breathing, was observed in a small study of late-onset Pompe disease (LOPD) patients who had ongoing respiratory dysfunction despite enzyme replacement therapy (ERT). “Our study provide new insights regarding respiratory mechanisms in LOPD,” the researchers wrote. Should their…

A powerful imaging technique called high-resolution intravital microscopy, or IVM, may be a useful tool for visualizing and quantifying the effectiveness of investigational treatments in mouse models of Pompe disease, according to recent research. The approach allows for cellular changes in muscles to be visualized in live animals. Using…

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…
