SUNRISE-FA is a multicenter, 52-week, dose-ascending, open-label trial evaluating the safety and preliminary efficacy of LX2006 in patients who have FA cardiomyopathy. LX2006 is administered as a one-time intravenous infusion to patients in at least two ascending-dose cohorts with the potential to escalate to a third cohort at a dose of 1.2×10¹² vg/kg. Investigators at Weill Cornell Medicine are conducting a Phase 1A study of AAVrh.10hFXN, known as LX2006 at Lexeo, in a single-site, 52-week, dose-ascending, open-label trial evaluating the safety and preliminary efficacy of AAVrh.10hFXN in patients who have FA cardiomyopathy. In the Weill Cornell trial, AAVrh.10hFXN is administered as a one-time intravenous infusion to patients in two ascending-dose cohorts with five participants per cohort. In April 2024, Lexeo licensed certain intellectual property rights including rights to current and future data generated from the ongoing Phase 1A trial of AAVrh.10hFXN conducted by Weill Cornell Medicine.
