Summary

This study tested an oral drug called venglustat in adults and children with late-onset Tay-Sachs or Sandhoff disease, rare genetic disorders that damage the nervous system. The goal was to see if the drug could reduce harmful substances in the brain and slow disease progression. The trial was terminated early, but data collected may help understand how to treat these conditions.
