Humacyte Announces Expansion of Intellectual Property for Pipeline Products with Granting of New U.S. Patent for Bioengineered Esophagus

– Patent covers esophagus produced using Humacyte’s proprietary bioengineered regenerative tissue platform, designed for implant in patients with damaged esophagus –

– Patent provides coverage into 2041 for the composition of novel bioengineered esophagus –

DURHAM, N.C., Sept. 29, 2025 (GLOBE NEWSWIRE) -- Humacyte, Inc. (Nasdaq: HUMA), a commercial-stage biotechnology platform company developing universally implantable, bioengineered human tissues at commercial scale, today announced the allowance of a U.S. Patent covering the composition of a bioengineered esophagus that can be produced using the Company’s proprietary regenerative tissue engineering platform. The patent, titled “Tubular Prostheses (Esophagus),” provides protection into 2041 of key structural and mechanical attributes for its designed use as an esophageal replacement including size, strength, and methods of production. Humacyte’s Tubular Prostheses patent family encompasses composition and methods claims for advanced tissue constructs intended to replace damaged airways, upper digestive, and urinary tracts in patients.

“Bioengineered trachea, esophagus, and urinary conduits represent novel treatment programs that target high unmet patient needs as well as highlight the versatility of our regenerative tissue engineering platform and the breadth of our product pipeline,” said Rob Kirkton, Ph.D., Executive Director of New Product and Process Development at Humacyte.   With the most recent grant of patent, Humacyte has now secured coverage for composition of matter for bioengineered trachea, esophagus, and urinary conduits in the United States, Europe, Canada, and Australia.   This represents an important expansion of the patent coverage for Humacyte’s platform.

Advanced tissue constructs for tracheal, esophageal, and urinary conduit replacement have been evaluated in early preclinical models with plans for future optimization and testing in large animal models. The advanced tissue construct product candidates are one component of Humacyte’s broad product pipeline that also includes acellular tissue engineered vessels (ATEV™), Coronary Tissue Engineered Vessels (CTEV) and the BioVascular Pancreas™ (BVP™). Each of these products can be produced using the same bioengineering technology and manufacturing platform as Humacyte’s Symvess™ product.

“We are pleased to continue to expand the protection surrounding our bioengineered tissue platform and related novel product candidates,” said Laura Niklason, M.D., Ph.D., Founder and Chief Executive Officer of Humacyte. “We plan to align ourselves with corporate partners where appropriate to accelerate the development of these programs.”

The esophageal replacement and other advanced tissue constructs are investigational products and have not been approved for sale by the FDA or any other regulatory agency.

About Humacyte

Humacyte, Inc. (Nasdaq: HUMA) is developing a disruptive biotechnology platform to deliver universally implantable bioengineered human tissues, advanced tissue constructs, and organ systems designed to improve the lives of patients and transform the practice of medicine. The Company develops and manufactures acellular tissues to treat a wide range of diseases, injuries, and chronic conditions. Humacyte’s initial product candidates, a portfolio of acellular tissue engineered vessels (ATEVs), are currently in late-stage clinical trials targeting multiple vascular applications, including vascular trauma repair, arteriovenous (AV) access for hemodialysis, and peripheral artery disease. A Biologics License Application for the ATEV in the vascular trauma indication was approved by the FDA in December 2024. Preclinical development is also underway in coronary artery bypass grafts, pediatric heart surgery, treatment of type 1 diabetes, and multiple novel cell and tissue applications. Humacyte’s 6mm ATEV for AV access in hemodialysis was the first product candidate to receive the FDA’s Regenerative Medicine Advanced Therapy (RMAT) designation and has also received FDA Fast Track designation. Humacyte’s 6mm ATEV for urgent arterial repair following extremity vascular trauma and for advanced PAD also have received an RMAT designations. The ATEV received priority designation for the treatment of vascular trauma by the U.S. Secretary of Defense. For more information, visit .

For uses other than the FDA approval in the extremity vascular trauma indication, the ATEV is an investigational product and has not been approved for sale by the FDA or any other regulatory agency.
