Twins do well on high-dose ERT plus immune tolerance induction

Early immune tolerance induction with rituximab, methotrexate, and intravenous (into-the-vein) immunoglobulin may have prevented twin babies with infantile-onset Pompe disease (IOPD) from developing antibodies against enzyme replacement therapy (ERT), according to a case report from the U.S. The report, “Optimizing clinical outcomes: The journey of twins with CRIM-negative…

Stem Cell Gene Therapy Blocks Anti-GAA Immune Response in Mice

Administrating a stem cell gene therapy before beginning enzyme-replacement therapy (ERT) prevented the development of antibodies against the acid alpha-glucosidase (GAA) enzyme, improved survival, and enhanced therapeutic benefits in a mouse model of Pompe disease, a recent study found. “Together, this study indicates that [stem cell] gene therapy induces…

Early ERT Key in Severe Classic Infantile Pompe

Early treatment with enzyme replacement therapy (ERT) and immune tolerance induction (ITI) greatly improved clinical outcomes for infants with the severe, frequently ERT-nonresponsive, CRIM-negative infantile Pompe disease (IPD), a study has found. “Our data suggest that the first few weeks after birth…
