NEW YORK, Aug. 12, 2024 (GLOBE NEWSWIRE) -- Lexeo Therapeutics, Inc. (Nasdaq: LXEO), a clinical stage genetic medicine company dedicated to pioneering treatments for genetically defined cardiovascular diseases and APOE4-associated Alzheimer’s disease, today reported second quarter 2024 financial results and provided operational highlights.

“We were proud to present the recent interim data of LX2006 for the treatment of FA cardiomyopathy, the first ever to show promise of treating this rare and fatal condition,” said R. Nolan Townsend, Chief Executive Officer of Lexeo Therapeutics. “Based on the favorable evidence to date, we have initiated engagements with FDA on surrogate endpoints for a registrational study so we can work to bring this potentially transformative gene therapy to patients as quickly as possible.”

Business and Program Updates

• LX2006 for the Treatment of FA Cardiomyopathy: In July 2024, Lexeo announced positive interim data of LX2006 across both the Lexeo SUNRISE-FA Phase 1/2 clinical trial (NCT05445323) and the Weill Cornell Medicine investigator-initiated Phase 1A trial (NCT05302271).
  • Safety and Tolerability: Interim safety results showed LX2006 was well tolerated with no treatment-related serious adverse events in either study.
  • Efficacy and Protein Expression: Sustained and consistent improvements were observed across multiple cardiac biomarkers associated with outcomes in FA cardiomyopathy, and increased frataxin protein levels were observed in all SUNRISE-FA participants post-treatment.
  • Regulatory Plans: In light of the evidence of treatment effect with improvements across multiple cardiac measures, Lexeo recently initiated formal engagements with FDA to discuss surrogate endpoints for a future registrational study and expects to provide an update on ongoing regulatory engagements by end of 2024. LX2006 was also granted Orphan Medicinal Product designation for the treatment of Friedreich ataxia by the European Commission in July 2024.
