Early treatment with at least two cycles of bortezomib may help lower the levels of antibodies that can make enzyme replacement therapy (ERT) less effective, according to a report of two young children with infantile-onset Pompe disease. The cases add to earlier reports that bortezomib, an injectable medication…

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…

Sanofi’s Nexviazyme (avalglucosidase alfa), an enzyme replacement therapy approved for Pompe disease, doesn’t appear to be linked to new or worsening diabetes, a concern raised by the presence of dextrose, a simple sugar, in the solution for infusion. In a study funded by Sanofi, researchers also…

A gene therapy designed to travel into muscles resulted in widespread production of the enzyme that’s missing or faulty in Pompe disease, according to a study that also describes a new rat model of the infantile-onset form of the disease. Researchers also observed that rats given a single…

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…

An easy survey of 20 questions agrees well with other tools used in clinical practice to measure physical function in people with late-onset Pompe disease (LOPD), according to a study that suggests it may aid in measuring and tracking symptoms over time. Having a reliable way to measure physical…

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…

Despite being on enzyme replacement therapy (ERT) for a long time, some children with infantile-onset Pompe disease (IOPD) can still develop problems in the brain and spinal cord, a small study suggests. Manifestations such as overactive bodily reflexes, encephalopathy (damage to the brain), and…

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…
