LX2006 Gene Therapy for Friedreich Ataxia Cardiomyopathy (FA-CM)
Official title: A Phase 2, Multicenter, Open-label, Randomized, Controlled Study of LX2006 Gene Therapy in Participants With Friedreich Ataxia Cardiomyopathy (SUNRISE-FA 2)
Run by Lexeo Therapeutics · NCT07721025 · Data updated 2026-11-12
A Phase 2 study tests LX2006 gene therapy in people with Friedreich ataxia who also have cardiomyopathy to see if it helps heart function and safety.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 6 years or older with confirmed Friedreich ataxia and cardiomyopathy meeting the specified cardiac and antibody criteria.
✕Probably not a fit
Patients with non-FA cardiomyopathy, uncontrolled comorbidities, or high anti-AAVrh.10 antibodies may derive less or no benefit.

What this trial studies
This multicenter, open-label, randomized, controlled Phase 2 trial evaluates the safety and potential benefit of LX2006 gene therapy in FA patients with cardiomyopathy. Participants must have FA with LV hypertrophy and an LV ejection fraction of at least 30%, and be eligible for AAVrh.10–based treatment. The intervention is LX2006 alongside usual care, with enrollment limited to institutions including University of South Florida under Lexeo Therapeutics leadership.
Why it matters
Potential benefit: If successful, LX2006 could improve heart function or slow disease progression in FA-CM.
How similar studies have gone: Previous gene therapy approaches in cardiomyopathy have yielded mixed results; this study explores a targeted gene therapy in a specific FA-related heart condition.
