Pompe disease is currently treated with enzyme replacement therapy (ERT) with recombinant human acid alpha-glucosidase (GAA). Here, the authors show hepatic-directed gene therapy with AAV vectors enhances GAA bioavailability compared with ERT, resulting in improved rescue of the disease phenotype in mice and broad enzyme distribution in mice and non-human primates.
