About Lexeo Therapeutics
Lexeo Therapeutics is a New York City-based, clinical stage genetic medicine company dedicated to reshaping heart health by applying pioneering science to fundamentally change how cardiovascular diseases are treated. The Company is advancing a portfolio of therapeutic candidates that take aim at the underlying genetic causes of conditions, including LX2006 in Friedreich ataxia (FA), LX2020 in plakophilin-2 (PKP2) arrhythmogenic cardiomyopathy, LX2022 in hypertrophic TNNI3 cardiomyopathy, and others in devastating diseases with high unmet need.

About LX2006
LX2006 is an AAV-based gene therapy candidate for the treatment of FA cardiomyopathy, the leading cause of death in individuals with FA which affects approximately 5,000 people in the United States. LX2006 is designed to systemically deliver a functional frataxin (FXN) gene to promote the expression of the frataxin protein and restore mitochondrial function in myocardial cells. LX2006 is being evaluated in two clinical trials, the Lexeo-sponsored SUNRISE-FA Phase 1/2 clinical trial (NCT05445323) and the Weill Cornell Medicine investigator-initiated Phase 1A trial (NCT05302271). LX2006 has been granted Breakthrough Therapy, Regenerative Medicine Advanced Therapy, Orphan Drug, Rare Pediatric Disease and Fast Track designations by the FDA, admitted into the FDA CMC Development and Readiness Pilot (CDRP) program, and granted orphan medicinal product designation by the European Commission.
