late-onset Pompe disease

A better understanding of Pompe disease-causing genetic mutations may help with early treatment intervention, even if symptoms are subtle, a small Hungarian study suggests. Researchers found that the precise localization of a mutation determines the impact on GAA enzyme activity, which in turn has been associated with disease onset.

Four new mutations in the GAA gene have been identified in a group of people with late-onset Pompe disease (LOPD), according to a study in Spain. The study “Genotype–phenotype correlation of 17 cases of Pompe disease in Spanish patients and identification of 4 novel GAA variants” was published in the Orphanet…

The type of genetic mutation carried by a Pompe disease patient appears to predict whether the disease is infantile- or late-onset, according to a study. However, newly diagnosed patients should still undergo complete genetic, cardiac, and neurological tests, scientists stated. The study, “Phenotypic implications of pathogenic…

Strength training exercises did not aggravate muscle damage in people with late-onset Pompe disease (LOPD), although patients with significant changes in certain markers of muscle damage should be monitored while determining their best training regime. This result comes from the study “Muscle damage in response to a…

AT-GAA, an investigational therapy by Amicus Therapeutics for late-onset Pompe disease, will be available to select patients in the U.K. through an early access program before its potential regulatory approval. Eligible patients are adults who have received the enzyme replacement therapy (ERT) alglucosidase alfa — the…

Amicus Therapeutics anticipates completing a rolling application by mid-year to seek approval of its investigational therapy AT-GAA for late-onset Pompe disease in the U.S. The announcement follows a pre-filing meeting with the U.S. Food and Drug Administration (FDA). The rolling biologics license application (BLA), initiated in…

Fat replacement of back, abdominal, and trunk muscles in late-onset Pompe disease (LOPD) correlates with diaphragm weakness and worsening respiratory function, a long-term clinical study has determined. “These results suggest that identification of fat replacement in these areas … should…

A Phase 1/2 trial is recruiting adults in the U.S. who have late-onset Pompe disease to test a gene therapy, AT845, being developed by Audentes Therapeutics, according to an update from the Muscular Dystrophy Association. The company-sponsored FORTIS trial (NCT04174105) will be evaluating the safety…

Patients with late-onset Pompe disease (LOPD) usually develop breathing problems as the disease progresses. If you have LOPD, you may eventually need ventilation to aid your breathing. Here is more information about how Pompe affects breathing and about ventilators that may help to ease the disease’s symptoms. How…

Spark Therapeutics has dosed the first patient in the Phase 1/2 RESOLUTE clinical trial of SPK-3006, an experimental gene therapy for people with late-onset Pompe disease (LOPD). “Dosing the first participant in the Phase 1/2 RESOLUTE trial of investigational SPK-3006 for late-onset Pompe disease is an important milestone and…
