late-onset Pompe disease

Age and the use of an assistive device like a walker may tell how well a patient with late-onset Pompe disease will do in a six-minute walk test (6MWT), a small study suggests. The 6MWT is considered a gold standard for determining, through difficulties in walking, the severity of…

The levels of BNIP3, a protein implicated in muscle fiber atrophy and increased autophagy — two features of late-onset Pompe disease (LOPD) — are increased in muscle samples from LOPD patients relative to healthy people, a small study shows. Autophagy is a pathway by which cells break down damaged…

Pain is relevant but appears to be unrelated to damage to small nerve fibers in the skin of late-onset Pompe disease patients who are using enzyme replacement therapy, a study found. The study, “Small fiber involvement is independent from clinical pain in late-onset Pompe disease,” was published in…

The investigational gene therapy ACT-101 overall was well-tolerated among three people with late-onset Pompe disease (LOPD) who were treated in a Phase 1/2 clinical trial. Moreover, the trial results also showed that treatment markedly increased levels of the GAA enzyme — deficient in Pompe disease — in the patients’ muscle…

Interruptions to Myozyme enzyme replacement therapy (ERT) regimens during the COVID-19 pandemic led to worsened motor symptoms and poorer respiratory function in patients with Pompe disease, a French study found. These decreases in motor and respiratory function — seen after just a couple of months — were not…

Infection by the virus that causes COVID-19 led to mild-to-moderate symptoms in four people with late-onset Pompe disease (LOPD) and pulmonary involvement, despite the increased risk of severe complications in such cases, scientists reported. “COVID-19 infection can result in a benign course in some patients with LOPD. However, individuals with LOPD…

Long-term treatment with Nexviazyme (avalglucosidase alfa) safely and effectively improves lung function and walking ability in children and adults with late-onset Pompe disease (LOPD), according to nearly two years of data from the Phase 3 COMET trial. These findings, along with positive long-term results from the Phase 2…

Acceptable safety is being seen to date in four adults with late-onset Pompe disease (LOPD) given the one-time gene therapy  AT845 in the FORTIS Phase 1/2 trial, its developer, Astellas Gene Therapies, announced. Interim study data in these four enrolled patients, as of the Dec. 3 cutoff date, shows…

Long-term treatment with Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — results in variable but satisfactory motor and respiratory outcomes among older adults recently diagnosed with late-onset Pompe disease (LOPD), a study from Germany reported. According to its researchers, these findings were…

People with late-onset Pompe disease (LOPD) do not show significant brain abnormalities or general cognitive impairment, in contrast with some patients with the classical infantile-onset form, a study shows. The study, “Is the brain involved in patients with late-onset Pompe disease?,” was published in the…
