DURHAM, N.C., Feb. 26, 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 commercial launch of Symvess (acellular tissue engineered vessel-tyod) for use in adults as a vascular conduit for extremity arterial injury when urgent revascularization is needed to avoid imminent limb loss, and when autologous vein graft is not feasible. The U.S. Food and Drug Administration (FDA) granted a full approval for Symvess on December 19, 2024. The FDA has now completed its required review of commercial batch information and has authorized Humacyte to commence commercial shipments.
Shortly after FDA approval, Humacyte began receiving requests for quotations for Symvess from hospitals. Twenty-one hospitals have already initiated the VAC approval process, with additional hospitals expected to commence the process. These hospitals are a mix of leading trauma centers that were participants in Humacyte clinical studies combined with institutions newly introduced to Symvess. Additionally, the hospitals span the range of individual institutions to centers providing access to larger hospital networks. Although the VAC process often takes three to six months to complete, two hospitals have already completed their review and approved the purchase of Symvess in advance of market launch. Humacyte has also been notified that a number of hospitals will purchase Symvess while the VAC process remains underway.
"This is a great moment for Humacyte but, more importantly, for patients in urgent need of arterial repair options to help save their limbs or lives." said Laura Niklason, M.D., Ph.D., Founder and Chief Executive Officer of Humacyte. "After more than 20 years of research and development, we are thrilled to be able to deliver Symvess to hospitals and surgeons who are committed to improving patient outcomes. This commercial launch signifies a new era in vascular surgery and patient care and is the next growth phase for Humacyte. Our commercial team will continue to work closely with health care providers to ensure that Symvess is available to patients nationwide."
Symvess, or the ATEV™ (acellular tissue engineered vessel), is a first-in-class bioengineered human tissue that is designed to be a universally implantable vascular conduit for use in arterial replacement and repair. In clinical studies, Symvess has been utilized by vascular and trauma surgeons in Level 1 Trauma centers throughout the U.S. and Israel to repair severe limb-threatening and life-threatening injuries, and in front-line hospitals in Ukraine to treat wartime injuries. In contrast to harvesting a vein from the patient, which causes further injury and takes valuable time, Symvess is available off-the-shelf, and does not require further injuring the patient. Humacyte's BLA included positive results from the V005 pivotal Phase 2/3 clinical study, as well as real-world evidence from the treatment of wartime injuries in Ukraine under a humanitarian aid program. Symvess has been used to treat many types of injuries arising from car accidents, gunshot wounds, blast wounds, and industrial accidents. Results from these civilian and wartime trauma studies were published in JAMA Surgery on November 20, 2024. In the clinical studies, Symvess was observed to have high rates of patency, or blood flow, and resulted in low rates of limb amputation and infection.
To communicate the health economic value of Symvess, Humacyte has developed a Budget Impact Model (BIM) based on the clinical results supporting the BLA, and the estimated reduction in clinical complications potentially achievable with the use of Symvess versus the current standard of care. Based on the BIM, the overall per-patient cost of treating patients with Symvess is estimated to be less than the cost of treating trauma patients with synthetic grafts, cryopreserved allografts, or xenografts. The major drivers of cost savings associated with Symvess stemmed from reductions in the rates of amputation and vascular conduit infection. A paper describing the BIM has already been accepted for publication in a major medical journal.
INDICATION
SYMVESS is an acellular tissue engineered vessel indicated for use in adults as a vascular conduit for extremity arterial injury when urgent revascularization is needed to avoid imminent limb loss, and autologous vein graft is not feasible.
IMPORTANT SAFETY INFORMATION
BOXED WARNING: GRAFT FAILURE
Loss of SYMVESS integrity due to mid-graft rupture or anastomotic failure can result in life threatening hemorrhage.
CONTRAINDICATIONS
DO NOT use SYMVESS in patients who have a medical condition that would preclude long-term antiplatelet therapy (such as aspirin or clopidogrel) after resolution of acute injuries.
WARNINGS AND PRECAUTIONS
Graft Rupture
Vascular graft rupture has occurred in patients treated with SYMVESS. Advise patients that arterial bleeding can be life-threatening and to seek emergent medical evaluation for any signs or symptoms of graft rupture such as bleeding, pain and swelling in the extremity, or signs of extremity ischemia.
Anastomotic Failure
Anastomotic failure has occurred in patients treated with SYMVESS. In clinical studies of SYMVESS, anastomotic failure occurred within the first 36 days post-implantation. Monitor patients for signs of anastomotic failure such as pain and swelling at the surgical site, decreasing hemoglobin or other signs and symptoms of bleeding. Advise patients to seek urgent medical evaluation if they have any signs or symptoms that may be indicative of anastomotic failure such as bleeding, swelling or worsening pain at the surgical site or changes in color of overlying skin.
Thrombosis
Thrombosis has occurred in patients treated with SYMVESS. In clinical trials of SYMVESS, patients received antiplatelet therapy following implantation of SYMVESS to reduce the risk of thrombosis. The risk of thrombosis may increase in patients who discontinue antiplatelet therapy. Anti-platelet therapy is recommended following treatment with SYMVESS.
Transmission of Infectious Diseases
SYMVESS is manufactured using cells and reagents that may transmit infectious diseases or infectious agents. The cells used in the manufacture of SYMVESS are derived from a donor who met the donor eligibility requirements for transmissible infectious diseases which includes screening and testing of risks associated with human immunodeficiency virus 1 (HIV-1), human immunodeficiency virus 2 (HIV-2), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis (Treponema pallidum). The cell banks are tested negative for human and animal viruses, retroviruses, bacteria, fungi, yeast, and mycoplasma. While all animal-derived reagents are tested for animal viruses, bacteria, fungi, and mycoplasma before use, these measures do not eliminate the risk of transmitting these or other transmissible infectious diseases and disease agents. Fetal bovine serum is sourced to minimize the risk of transmitting a prion protein that causes bovine spongiform encephalopathy and the cause of a rare fatal condition in humans called variant Creutzfeldt-Jakob disease. No transmissible agent infections have been reported during clinical testing.
ADVERSE REACTIONS
The most common adverse reactions (occurring at = 10%), were vascular graft thrombosis, pyrexia (fever) and pain.
