Using self-reported outcomes by adults with Pompe disease, researchers were able to estimate the minimal clinically important difference or MCID — the smallest outcome change that a patient perceives as important following treatment — after one year of enzyme replacement therapy (ERT). The differences reported by patients as clinically…

Long-term treatment with Pombiliti plus Opfolda (cipaglucosidase alfa/miglustat) safely improved motor function and stabilized or enhanced lung function in adults with late-onset Pompe disease (LOPD), according to newly published data from two clinical trials. Pompe disease is marked by a deficiency in an enzyme called acid alpha-glucosidase…

Switching from Lumizyme (alglucosidase alfa) to Nexviazyme (avalglucosidase alfa) was shown to improve breathing and motor function for most people with late-onset Pompe disease (LOPD) in a small real-world study. Many of the improvements, such as those seen in walking ability, were minimal, and did not reach…

Children with classic infantile-onset Pompe disease (IOPD), who were first treated as infants with Myozyme (alglucosidase alfa) — sold as Lumizyme in the U.S. — continue to experience heart, breathing, and cognitive deficits, as well as motor problems, despite long-term use of the older therapy, a small German…

Disease severity varied widely among adults with late-onset Pompe disease who underwent screening to assess their eligibility to participate in a gene therapy clinical trial, a study reports. Elevated levels of antibodies against the viral delivery vector were one of the exclusion criteria, suggesting that future studies may use…

Hypersensitive reactions to infusions of enzyme replacement therapies (ERT) to treat late-onset Pompe disease (LOPD) were primarily mild and nonallergic, a small study reported. Many reactions were reported after a year of well tolerated ERT and most of them occurred in women, data showed. After the reactions, the ERT…

Motor problems in people with Pompe disease may be explained by damage to muscle spindles, which are sensory receptors that detect muscle movement and help regulate muscle tone and maintain posture, a mouse study suggested. Muscle spindle structure and function were “severely compromised” in Pompe mice, resulting in a…

Pombiliti (cipaglucosidase alfa), a component of AT-GAA, a two-part investigational therapy, has been approved to treat adults with late-onset Pompe disease (LOPD) in the European Union. The European Commission (EC) ruling comes on the heels of a positive opinion issued by the Committee for Medicinal Products for Human…

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…

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…
