Pursuant to the License Agreement, Cornell has granted the Company an exclusive license to practice under certain patent rights generated in animal studies conducted by Cornell on behalf of the Company and a non-exclusive license to know-how concerning a gene therapy for Friedreich’s ataxia (“FA”) cardiomyopathy and current and future data generated in an ongoing investigator-initiated Phase 1A trial of AAVrh.10hFXN to treat FA cardiomyopathy. Both licenses are worldwide and cover products with human and non-human prophylactic and therapeutic uses. Cornell has also granted the Company a right of reference to Cornell’s Investigation New Drug application for a gene therapy for FA cardiomyopathy.
The License Agreement provides that Company will pay a license issue fee and an initial data transfer fee to Cornell totaling $600,000 and thereafter pay an annual data transfer fee of $50,000 until data is no longer being gathered. The Company has agreed to pay annual license maintenance fees ranging from $2,500 to $25,000 until such time Company commercializes a licensed product. In addition, the Company will pay Cornell up to an aggregate of $2.1 million in regulatory milestones and up to an aggregate of $100 million in commercial milestones, plus low single digit royalties on net sales.
The License Agreement contains other customary license terms including terms related to sublicensing, development, commercialization, milestones, royalties, intellectual property, and termination. Upon expiration of the applicable royalty term for a product in a given country, the Company shall retain a non-exclusive, royalty free license to the data and know-how, including to continue selling such product in that country.
Cornell may terminate the License Agreement if the Company (a) breaches the License Agreement (subject to a cure period), (b) participates in any proceeding challenging the validity of the licensed patents, (c) publishes the licensed data without Cornell’s prior written consent, or (d) does not reach certain milestones. Cornell may also terminate the License Agreement in part on product-by-product basis if the Company does not diligently develop and sale a product. The Company may terminate the License Agreement, in whole or in part with respect to the right of reference, or the licensed data, know-how, or patent rights, with 90 days’ prior written notice to Cornell.
The foregoing summary of the material terms of the License Agreement is qualified in its entirety by the terms of the License Agreement, a copy of which will be filed as an exhibit in a subsequent periodic report to be filed under the Securities Exchange Act of 1934, as amended.

Lexeo Therapeutics Announces License Agreement to Accelerate Development of LX2006 for the Treatment of Friedreich Ataxia Cardiomyopathy
Lexeo Therapeutics gains intellectual property rights including current and future clinical data from ongoing Weill Cornell Medicine investigator-initiated trial of gene therapy candidate AAVrh.10hFXN (LX2006) to support regulatory discussions
Together with Lexeo Therapeutics’ ongoing study of LX2006, a total of 11 participants have been treated to date; includes patients at treatment durations out to 18-months with no treatment-related serious adverse events observed across either study
Interim readout of combined data set at multiple doses expected mid-year 2024
NEW YORK – April 22, 2024 (GLOBE NEWSWIRE) – Lexeo Therapeutics, Inc. (Nasdaq: LXEO), a clinical stage genetic medicine company, today announced an in-license agreement with Cornell University to expedite development of the investigational gene therapy candidate LX2006 for the treatment of Friedreich ataxia (FA) cardiomyopathy.
Under the license agreement, Lexeo has acquired certain rights1including rights to current and future data generated in an ongoing investigator-initiated Phase 1A trial of AAVrh.10hFXN to treat FA cardiomyopathy (NCT05302271). The agreement will support Lexeo’s efforts to develop a potentially life-changing therapy for this unmet need.
The investigator-initiated trial is being conducted by Weill Cornell Medicine, which has pioneered groundbreaking research on the potential of gene therapy in FA, published preclinical data that supported the first ever gene therapy IND clearance for FA, and sponsored a natural history study for almost a decade to better characterize the condition and its progression. Lexeo previously licensed know-how relating to AAVrh.10hFXN from Weill Cornell Medicine and collaborated with researchers there to further study the candidate, which Lexeo refers to as LX2006. Lexeo is studying LX2006 in the company-sponsored, open label, dose-ascending, multicenter SUNRISE-FA Phase 1/2 trial (NCT05445323), in which four patients have been dosed to date across cohorts 1 & 2. Weill Cornell Medicine has dosed seven patients to date with LX2006 across dose cohorts 1 & 2 and is collecting biomarker, structural, and functional cardiac data akin to SUNRISE-FA.
“The larger aggregate data set, combined with Orphan Drug, Rare Pediatric Disease, and Fast Track designations from FDA, is anticipated to facilitate an accelerated path to regulatory engagements for LX2006,” said R. Nolan Townsend, Chief Executive Officer of Lexeo Therapeutics. “We are excited about the opportunity to advance research in FA cardiomyopathy, which is the leading cause of death in FA and has no approved treatment options today.”
The interim clinical data readout of LX2006 is expected mid-year 2024. With the newly-licensed data, the readout will now include participants across the two studies, approximately doubling the number of evaluable patients and including patients with a treatment duration out to 18-months. Lexeo also expects to provide an analysis of natural history data and baseline characteristics for study participants from both studies to characterize the cardiovascular disease phenotype seen in FA cardiomyopathy ahead of the interim readout.
“This agreement with Lexeo Therapeutics builds upon years of collaboration between Weill Cornell Medicine and Lexeo to benefit patients with FA cardiomyopathy. It is our intention that this license agreement will accelerate the clinical investigation and development of LX2006 as a potential life-saving therapy for patients with FA,” said Dr. Lisa Placanica, Senior Managing Director, Center for Technology Licensing at Weill Cornell Medicine.

Note: Cardiac biopsies are performed only in the SUNRISE-FA trial; one patient in dose cohort 1 and three patients in dose cohort 2 have undergone cardiac biopsies.
The Phase 1A study of AAVrh.10hFXN conducted by investigators at Weill Cornell Medicine is a single-site, 52-week, dose-ascending, open-label trial evaluating the safety and preliminary efficacy of AAVrh.10hFXN in patients who have FA cardiomyopathy. AAVrh.10hFXN is administered as a one-time intravenous infusion to patients in two ascending-dose cohorts with five participants per cohort. While cardiac biopsies are not collected in this study, key cardiac disease measures are collected at 3, 6 and 12-month intervals and complement data collected in SUNRISE-FA.
SUNRISE-FA is a multicenter, 52-week, dose-ascending, open-label trial evaluating the safety and preliminary efficacy of LX2006 in patients who have FA cardiomyopathy. LX2006 is administered as a one-time intravenous infusion to patients in at least two ascending-dose cohorts with the potential to escalate to a third cohort at a dose of 1.2x1012 vg/kg. Long-term safety and efficacy will be evaluated for five years following dosing in both trials.
About LX2006
LX2006 is an AAV-based gene therapy candidate delivered intravenously for the treatment of FA cardiomyopathy, the most common cause of mortality in patients with FA affecting approximately 5,000 patients in the United States. LX2006 is designed to target the cardiac manifestations of FA by delivering a functional frataxin gene to promote the expression of the frataxin protein and restore mitochondrial function in myocardial cells. In preclinical studies, LX2006 reversed the cardiac abnormalities in FA disease models and showed improvement in cardiac function and survival while demonstrating a favorable safety profile. The FDA has granted Rare Pediatric Disease designation, Fast Track designation, and Orphan Drug designation to LX2006 for the treatment of FA cardiomyopathy.
