LEXEO Message to the Friedreich Ataxia Community

Message to the Friedreich Ataxia Community. October 7, 2025​.

This morning, we were pleased to share positive interim clinical data for LX2006, our investigational gene therapy, that includes both cardiac and neurological outcome measures. LX2006 (AAVrh10hFXN) is currently being studied in the Lexeo-sponsored SUNRISE-FA Phase 1/2 clinical trial and the Weill Cornell Medicine investigatorinitiated Phase 1A trial for the treatment of Friedreich ataxia cardiomyopathy.

Frataxin depletion leads to decreased soma size and activation of AMPK metabolic pathway in dorsal root ganglia sensory neurons

Frataxin depletion leads to decreased soma size and activation of AMPK metabolic pathway in dorsal root ganglia sensory neurons Olivier Griso, Deepika Mokkachamy Chellapandi, Amelie Weiss, Ioannis Manolaras, Helene Puccio. bioRxiv 2025.10.07.680891; doi:10.1101/2025.10.07.680891 

Our findings uncover AMPK-mTOR dysregulation as a key driver of neuronal growth impairment in FA. This robust neuronal model provides new insights into proprioceptive neuron vulnerability and offers a platform for therapeutic discovery.
