Humacyte Announces Publication Highlighting the First Use of the Human Acellular Vessel (HAV™) as Arterial Bypass Conduit for Replacement of Infected Prosthetic Graft

Dec 15, 2021

-- Vanderbilt University Medical Center patient received the HAV under the U.S. Food and Drug Administration’s (FDA) Expanded Access Program (EAP) in April 2019 --

-- After replacement, the patient resumed regular physical activity with no signs of infection of the HAV implant observed --

-- Published in Journal of Vascular Surgery: Cases, Innovations and Techniques --

-- HAV used in 20 EAP cases to date, for treatment of severe vascular disease and trauma --

DURHAM, N.C., Dec. 15, 2021 (GLOBE NEWSWIRE) -- Humacyte, Inc. (Nasdaq: HUMA), a clinical-stage biotechnology platform company developing universally implantable bioengineered human tissue at commercial scale, today announced that results from a case study of a patient who received the human acellular vessel (HAV) as a replacement for an infected synthetic iliofemoral bypass graft have been published online in the Journal of Vascular Surgery: Cases, Innovations and Techniques (JVSCIT). The manuscript, entitled “Surgical management of an infected external iliac artery interposition graft with a bioengineered human acellular vessel,” reports the first use of the HAV in the treatment of a patient with an infected prosthetic vascular graft, a procedure performed in April 2019 under an expanded access use authorized by the FDA.

The case report describes a 42-year-old female patient with a medical history of a right external iliac artery endofibrosis (EIAE) who had ipsilateral claudication and a persistently infected synthetic iliofemoral bypass graft replaced with a bioengineered HAV. Twenty-two months post-implantation, the patient demonstrated significant clinical improvement and had resumed regular physical activity. In addition, no signs of infection of the HAV implant have been observed. The patient’s story can be viewed here:

“Very few techniques exist that provide durable long-term or permanent solutions to vascular reconstruction,” said Thomas Naslund, M.D., of Vanderbilt University Medical Center and co-author on the case study. “The potential of the investigational HAV to populate with the patient's own cells and become a part of the patient's own DNA and own tissue, and thereby be durable over time and free from complications that threaten other types of conduits, warrants further evaluation as a replacement for infected synthetic vascular grafts.”

“While the HAV is being evaluated in multiple international multicenter clinical trials in vascular trauma, arteriovenous access for dialysis, and peripheral arterial disease (PAD), with over 460 HAV implants to date and more than 900 years of cumulative patient exposure, this was the first use of the HAV to replace an infected synthetic graft,” said Laura Niklason, M.D., Ph.D., Chief Executive Officer of Humacyte. “We are pleased that the HAV has continued to function in this patient over an extended period of time. The challenging cases experienced under the EAP program continue to show the potential of our bioengineered tissue platform to redefine what’s possible in regenerative medicine.”

The patient received the HAV, following approval of the EAP from the FDA, at the Vanderbilt University Medical Center. The HAV has been used in other EAP cases for patients with peripheral arterial disease (PAD) and vascular trauma, for which there are limited treatment options. In October, the Mayo Clinic in Rochester, Minn. filed an Investigational New Drug application #27864 with FDA. This IND will allow Mayo Clinic surgeons access to the investigational HAV for treatment of severe PAD in up to 25 patients who lack options for surgical bypass to restore adequate blood flow to the leg, which if left untreated can lead to amputation. The HAV is an investigational product candidate and is not currently approved for sale by the FDA or any international regulatory authority. For more information on Humacyte’s EAP for HAV, visit

About HAV
Human Acellular Vessels (HAV) are engineered off-the-shelf replacement vessels initially being developed for vascular repair, reconstruction and replacement. HAV is intended to overcome long-standing limitations in vessel tissue repair and replacement – it can be manufactured at commercial scale, it eliminates the need for harvesting a vessel from a patient, and clinical evidence suggests that it is non-immunogenic, infection-resistant, and can become durable living tissue. HAV is currently being evaluated in two Phase 3 trials in arteriovenous access and a Phase 2/3 trial for vascular trauma, and has been used in more than 460 patient implantations. It is the first product to receive Regenerative Medicine Advanced Therapy (RMAT) designation from the U.S. Food and Drug Administration (FDA), and has also received FDA Fast Track designation.

About Humacyte
Humacyte, Inc. (Nasdaq: HUMA) is developing a disruptive biotechnology platform to deliver universally implantable bioengineered human tissues and organs 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 opportunity, a portfolio of human acellular vessels (HAVs), is currently in late-stage clinical trials targeting multiple vascular applications, including vascular trauma repair, arteriovenous access for hemodialysis, and peripheral arterial disease. Pre-clinical 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 HAVs were the first product to receive the FDA’s Regenerative Medicine Advanced Therapy (RMAT) expedited review designation and received priority designation for the treatment of vascular trauma by the U.S. Secretary of Defense.
