The Company submitted manufacturing comparability data showing similar frataxin expression between its current HEK293 process and the future Sf9-baculovirus platform. Interim data from 16 participants showed sustained improvements in cardiac and neurologic measures.

Low-dose participants showed stable or improved cardiac parameters.
