(Nasdaq: HUMA), a commercial-stage biotechnology platform company developing universally implantable, bioengineered human tissues at commercial scale, today announced the presentation of research providing evidence of self-repair of the acellular tissue engineered vessel (ATEV) after cannulation for dialysis access at the Vascular Access Society of the Americas (VASA) 2026 Vascular Access for Dialysis Symposium in Salt Lake City, Utah. The presentation, titled “Self-repair of Acellular Tissue Engineered Vessels (ATEV) after Cannulation for Dialysis Access,” was delivered by Maisha Clancy, MA, Process Development Engineer at Humacyte. Research demonstrated that despite repeated cannulations for dialysis access, the ATEV was observed to maintain long-term structural integrity self-repair with smooth muscle cell repopulation in explants up to 5.5 years post-implantation. Arteriovenous (AV) fistulas remain the standard of care for vascular access in patients undergoing dialysis, with arteriovenous grafts, including ePTFE grafts, also used as alternatives. Both types require frequent cannulation to provide access to the patient’s blood for dialysis, often exceeding 300 needle punctures annually. Repetitive cannulation can damage the conduit wall and endothelium, contributing to hematoma, pseudoaneurysm, infection, thrombosis, and stenosis. Under the research program presented at the VASA meeting, histological characterization of cannulation tracts was performed in explanted ATEV and ePTFE samples that had been used as AV access conduits for up to 5.5 years. Researchers observed that despite repeated cannulations, ATEVs maintained long-term structural integrity in explants up to 5.5 years post-implantation. Repeated cannulation sites in the ATEVs showed evidence of self-repair, with smooth muscle cell repopulation of the graft wall and access tracts. Functional tissue remodeling occurred at the ATEV cannulation sites, including capillary ingrowth and organized collagen deposition with predominant collagen III expression. Growth factor, glycoprotein, and proteoglycan presence was observed, evidencing matrix regeneration in the ATEVs. In cannulation sites and cannulation adjacent walls, ATEVs were observed to have greater resistance to bacterial infection than ePTFE grafts. "These findings support the continued evaluation of ATEVs as a potential durable, self-repairing, and infection-resistant vascular access solution for long-term hemodialysis in patients at high risk for AV fistula failure," said Clancy. "The observations of lower grade injury in ATEVs, together with evidence of active cellular repair and bacterial containment, highlights their regenerative capacity and ability to support improved host defenses." Humacyte anticipates that top-line interim results from its ongoing V012 Phase 3 study in dialysis access will be available for reporting on June 11, 2026 at the Society of Vascular Surgery’s (SVS) Vascular Annual Meeting (VAM) in Boston. The V012 study is specifically focused on female patients with end-stage renal disease (ESRD) requiring dialysis, a population in which results from the completed V007 Phase 3 trial already showed meaningful advantages for ATEV over AV fistulas. Subject to results from the V012 study, Humacyte plans to submit a supplemental Biologics License Application (sBLA) for a second indication in AV access for hemodialysis during the second half of 2026. 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. 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 Biologics License Application for the acellular tissue engineered vessel (ATEV) in the vascular trauma indication was approved by the FDA in December 2024. ATEVs are also currently in late-stage clinical trials targeting other vascular applications, including arteriovenous (AV) access for hemodialysis and peripheral artery disease (PAD). 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 RMAT designations. The ATEV received priority designation for the treatment of vascular trauma by the U.S. Secretary of Defense.
