Management Comments

• We have made significant progress over the last few months across all our clinical stage programs, including reaching alignment with the FDA on registrational endpoints to support an accelerated approval pathway for LX2006, said R. Nolan Townsend, Chief Executive Officer of Lexeo Therapeutics.
• We believe this highly constructive feedback, along with RMAT designation, positions us to rapidly advance this promising potential treatment in a pivotal clinical study.
• With enrollment completed in the LX2006 SUNRISE-FA Phase 1/2 trial in Friedreich ataxia cardiomyopathy and in the first cohort of the LX2020 HEROIC-PKP2 Phase 1/2 trial in PKP2-ACM, we look forward to sharing meaningful updates across our cardiac gene therapy programs in 2025.

Industry Context

This announcement highlights Lexeo's progress in the competitive gene therapy space, particularly in addressing rare cardiovascular diseases and Alzheimer's. The RMAT designation and FDA alignment are significant milestones that could accelerate the development of LX2006, positioning Lexeo as a key player in this field.

Comparison to Industry Standards

• The RMAT designation for LX2006 is similar to other companies that have received this designation for their gene therapies, such as Sarepta Therapeutics for its Duchenne muscular dystrophy treatment.
• The use of LVMI and frataxin expression as co-primary endpoints is a novel approach in the treatment of FA cardiomyopathy, setting Lexeo apart from other companies in the space.
• The reported increase in frataxin protein expression of 35% and 279% increase in frataxin positive area in one participant is a positive result compared to other gene therapy trials targeting similar conditions.
• The cash runway into 2027 is a strong position compared to other clinical stage biotech companies that often require frequent capital raises.

Management Changes

Stakeholder Impact

• Shareholders will likely react positively to the clinical progress and RMAT designation.
• Employees may be encouraged by the company's progress and financial stability.
• Patients with Friedreich ataxia and PKP2-ACM may have increased hope for new treatment options.
