Lexeo Therapeutics, Inc. Provides Update on Cardiac Portfolio

Lexeo Therapeutics, Inc. provided business updates across its portfolio of programs. Business and Program Updates: LX2006 for the Treatment of FA Cardiomyopathy: Regulatory Update: Alignment on key elements of accelerated development pathway following a Type C meeting with the U.S. Food and Drug Administration (FDA): Increase in frataxin expression and reduction in left ventricular mass index (LVMI) as co-primary registrational endpoints to support accelerated approval; Target levels including 10% reduction in LVMI and 40% frataxin positive area as measured by immunohistochemistry (IHC); Histology-based measurement of frataxin and cardiac MRI as acceptable measurement tools; Use of secondary endpoints including left ventricular wall thickness and troponin as supportive measures of efficacy; Enrollment of participants with elevated LVMI in pivotal trial; Final dose selection and size of registrational trial alignment expected in 2025 guided by cohort 3 cardiac biopsy results; RMAT Designation: In October 2024, the FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation for LX2006 for the treatment of FA cardiomyopathy based on interim clinical data announced in July 2024. RMAT designation is granted for regenerative medicines that are intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition with preliminary clinical evidence that indicates the therapy has the potential to address unmet medical needs. This designation permits sponsor companies to have early and frequent interactions with the FDA through BLA filing. Completion of Enrollment of SUNRISE-FA: Completion of enrollment of SUNRISE-FA Phase 1/2 trial, with four participants administered LX2006 in cohort 3. To date, eight participants have received LX2006 in SUNRISE-FA and eight participants have received LX2006 in an ongoing Weill Cornell-sponsored investigator-initiated trial. International Congress for Ataxia Research (ICAR) Presentation: Lexeo will share new cardiac biopsy data from one participant in cohort 2 and functional scales from three participants in the Lexeo-sponsored SUNRISE-FA trial at ICAR on November 15, 2024. One Newly Reported Cardiac Biopsy Result from Cohort 2: Observed a 35% increase in frataxin protein expression from baseline as measured by liquid chromatography mass spectrometry (LCMS), and a 279% increase from baseline in frataxin positive area from 7% pre-treatment to 26% post-treatment from baseline as measured by IHC. The post-treatment average across cohort 1 and cohort 2 biopsy samples is 44% frataxin positive area as measured by IHC. Newly Reported Functional Results from July 2024 Interim Data Set: All three participants had more than a 5-point improvement in the Kansas City Cardiomyopathy Questionnare-12 (KCCQ-12) and at least a 1-point improvement in the modified Friedreich Ataxia Rating Scale (mFARS) as of their latest visit (2 participants at 12-months, and 1 participant at 6-months). LX2006 Continues to be Generally Well Tolerated: LX2006 has been generally well tolerated across both SUNRISE-FA and Weill Cornell investigator-initiated trials to date. One possibly treatment-related Grade 2 event of asymptomatic myocarditis was observed one year after dosing in a participant with multiple comorbidities and history of flu-like symptoms prior to diagnosis, which may have been a contributing factor. A biopsy was performed six weeks after initial diagnosis and results were negative for myocarditis; participant remains asymptomatic. LX2020 for the Treatment of PKP2-ACM: Completed enrollment of cohort 1 (n=3) of HEROIC-PKP2 Phase 1/2 trial. LX2020 has been generally well tolerated to date, with no evidence of complement activation and no unexpected safety events or toxicities associated with study drug observed. Anticipate proceeding to cohort 2 following data review by independent data safety and monitoring board. Initial data from cohort 1 with a focus on safety and biodistribution as assessed via cardiac biopsy expected in late First Quarter /early Second Quarter 2025. LX1001 for the Treatment of APOE4-associated Alzheimer’s Disease: Announced positive interim Phase 1/2 results for LX1001 at the CTAD conference. LX1001 was generally well tolerated to date across all dose cohorts with no reports of amyloid-related imaging abnormalities (ARIA). A dose and time-dependent increase in neuroprotective APOE2 expression was observed in all participants with ongoing durability at 12 months, and reductions in CSF tau biomarkers and tau PET were seen in a majority of participants.
