Lafora disease (LD) is a devastating childhood epilepsy caused by intracellular, aberrant glycogen aggregates called Lafora bodies (LBs) in the brain and other tissues. Herein, Brewer et al. generated a first-in-class antibody-enzyme fusion, VAL-0417, that degrades LBs in vitro and in vivo in a pre-clinical model, showing promise as a LD drug.
