Recently initiated formal engagements with FDA on surrogate endpoints for LX2006 registrational study;

expects to provide update by end of year

Phase 1/2 clinical trial of LX2020 (HEROIC-PKP2) currently recruiting patients; data update from Cohort 1 on track for 2H 2024

Cash and cash equivalents of $175.0 million expected to provide operational runway into 2027

NEW YORK – August 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 to date 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.
  • Appointment of Tim Van Hauwermeiren to Board of Directors: In July 2024, Lexeo announced the appointment of Tim Van Hauwermeiren to its Board of Directors. Mr. Van Hauwermeiren currently serves as the co-founder and CEO of argenx SE, a global immunology company focused on severe autoimmune diseases, and he brings over 20 years of life sciences business development and general management experience to Lexeo.

Expected Upcoming Milestones

  • LX2006 for the treatment of Friedreich ataxia cardiomyopathy
  • Previously disclosed data, and one additional cardiac biopsy from Cohort 2, will be shared at a scientific conference in Fall 2024
  • Update on ongoing regulatory engagements expected by end of 2024

Words such as “may,” “might,” “will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “design,” “estimate,” “predict,” “potential,” “develop,” “plan” or the negative of these terms, and similar expressions, or statements regarding intent, belief, or current expectations, are forward-looking statements. While Lexeo believes these forward-looking statements are reasonable, undue reliance should not be placed on any such forward-looking statements. These forward-looking statements are based upon current information available to the company as well as certain estimates and assumptions and are subject to various risks and uncertainties (including, without limitation, those set forth in Lexeo’s filings with the U.S. Securities and Exchange Commission (SEC)), many of which are beyond the company’s control and subject to change. Actual results could be materially different from those indicated by such forward-looking statements as a result of many factors, including but not limited to: risks and uncertainties related to global macroeconomic conditions and related volatility; expectations regarding the initiation, progress, and expected results of Lexeo’s preclinical studies, clinical trials and research and development programs; the unpredictable relationship between preclinical study results and clinical study results; delays in submission of regulatory filings or failure to receive regulatory approval; liquidity and capital resources; and other risks and uncertainties identified in Lexeo’s Annual Report on Form 10-K for the annual period ended December 31, 2023, filed with the SEC on March 11, 2024, Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2024, filed with the SEC on May 9, 2024, and subsequent future filings Lexeo may make with the SEC.
