Up to $40 Million Private Equity Financing into a New Entity Addressing Cardiac Genetic Diseases that Existing AAV Platforms are Unable to Treat

Lexeo Contributing Expertise and Know-How in Cardiac Genetic Medicines, Preclinical Intellectual Property, and Technology, in Combination with Novel Non-Viral RNA Delivery Platform

Represents Pipeline Diversification and Advancement of Leading-Edge Cardiovascular Science

NEW YORK, June 24, 2025 (GLOBE NEWSWIRE) -- Lexeo Therapeutics, Inc. (Nasdaq: LXEO), a clinical stage genetic medicine company dedicated to pioneering novel treatments for cardiovascular diseases, today announced a strategic partnership to develop therapies for genetic cardiac diseases utilizing a novel non-viral RNA platform. Combined with investment of up to $40 million from leading life-sciences investors Perceptive Xontogeny Venture Funds (“PXV Funds”) and venBio Partners (“venBio”), the partnership seeks to further revolutionize the treatment of cardiovascular diseases. The proceeds will be used to seed a new entity, the funding of which is non-dilutive to existing Lexeo shareholders.

“Delivery of DNA by adeno-associated virus has defined the first wave of genetic medicine, with potential to treat cardiovascular diseases that other modalities cannot address today. Over the next decade, however, new modalities will emerge allowing genetic medicines to treat an even broader range of cardiac diseases, and RNA therapeutics mediated by non-viral delivery are representative of this future,” said R. Nolan Townsend, Chief Executive Officer of Lexeo Therapeutics. “This partnership reflects an innovative approach to realize the therapeutic and economic value of promising preclinical science in a manner that benefits all stakeholders.”

Under the terms of the agreement, the new entity will be focused on advancing research for novel RNA-based therapeutics via non-viral delivery for the treatment of genetically mediated cardiac conditions. Lexeo will contribute its expertise in developing cardiac genetic medicines, certain existing preclinical intellectual property, and technology, which will be combined with a novel non-viral delivery platform.   As consideration for its contributions, at transaction close Lexeo has received a double-digit percentage equity position in the new entity and will be entitled to future milestone payments, royalties, and opt-in rights to certain program(s).

“The genetic and precision cardiology market is estimated to be worth over $13 billion this year, and it is expected to grow to almost $40 billion by 2033,” said Fred Callori, PXV Funds Managing Director. “We see this as one of the most promising areas in biotech, where there is both a significant need and clear opportunity for innovation through the development of RNA therapeutics for cardiac disease. This collaboration brings together the right expertise, science, and strategic areas of focus to pursue and advance these treatments.”

Corey Goodman, venBio Managing Partner, added: “Lexeo is a leader in cardiac genetic medicine and there is a significant unmet need for broadening precision approaches in this category. We look forward to working with Lexeo to launch this new entity and foster innovation that has the potential to fundamentally change the treatment paradigm for patients with devastating heart conditions.”
