extremity arterial injury medical

"patients with extremity arterial injury. The average hospital charge"

An extremity arterial injury is damage to a major blood vessel in an arm or leg that disrupts blood flow, causing severe bleeding, pain, or risk of tissue death and possible amputation if not fixed quickly. For investors, it matters because treatment often requires urgent surgery, specialized devices, or long rehabilitation—events that drive demand for medical products, affect hospital costs and reimbursement, and can change the financial outlook for healthcare providers and device makers, much like a sudden breakdown forcing expensive repairs.

autologous vein medical

"Patients undergoing extremity arterial injury repairs using autologous vein, synthetic grafts"

An autologous vein is a blood vessel taken from a patient’s own body and reused in a medical procedure, such as bypass surgery or vascular grafting. For investors, its use matters because procedures that rely on a patient’s own tissue can affect demand for surgical devices, influence clinical outcomes and complication rates, and shape regulatory and reimbursement decisions—much like choosing to repair a car with original parts versus aftermarket ones.

synthetic grafts medical

"repairs using autologous vein, synthetic grafts, and other biological conduits"

Synthetic grafts are man‑made medical implants used to replace, repair or bridge damaged body tissues such as blood vessels, skin or bone; think of them as a factory‑made patch or scaffold that helps the body restore function. Investors watch them because approval, safety, durability and cost determine how widely doctors will use the products, which directly affects sales, liability exposure and reimbursement in the healthcare market.

generalized linear models technical

"Healthcare costs were analyzed using logit and generalized linear models."

Generalized linear models are a family of statistical tools that link one or more input factors (like economic indicators or company metrics) to an outcome (such as returns, default risk, or demand) while allowing for different types of relationships and error behavior. Think of them as flexible recipes that choose the right cooking method for different ingredients; they matter to investors because they turn raw data into testable predictions and risk estimates that guide trading, valuation, and portfolio decisions.

rhabdomyolysis medical

"amputation, and rhabdomyolysis (severe ischemic damage to muscles)."

Rhabdomyolysis is a condition where muscle fibers break down and release proteins and salts into the bloodstream, like a burst pipe leaking debris into a home's plumbing. It can damage the kidneys and require hospitalization. For investors, reports of rhabdomyolysis tied to a drug, medical device, supplement or procedure can lead to safety warnings, regulatory action, costly recalls or legal liability, any of which can significantly affect a company’s finances and stock price.

anastomotic failure medical

"Anastomotic failure has occurred in patients treated with Symvess."

Anastomotic failure is when a surgical connection between two bodily structures—most often sections of intestine—is unable to hold and leaks, separates, or closes. For investors, it matters because such failures can increase patient complications, lengthen hospital stays, raise treatment costs, trigger product recalls or lawsuits, and slow or block regulatory approvals and market adoption of surgical devices, materials, or therapies designed to create or protect these joins.

thrombosis medical

"Thrombosis has occurred in patients treated with Symvess."

Thrombosis is the formation of a blood clot inside a blood vessel that can block normal blood flow, like a plaster clogging a pipe. It matters to investors because clotting events affect the safety profile and regulatory review of drugs, medical devices and treatments, can drive costly litigation or recalls, and influence healthcare demand and company valuations tied to patient outcomes and product approvals.

antiplatelet therapy medical

"preclude long-term antiplatelet therapy (such as aspirin or clopidogrel)"

Antiplatelet therapy uses medicines that make blood platelets less likely to stick together, lowering the chance blood clots will form. Think of platelets as tiny workers or glue patches that seal leaks in blood vessels; these drugs reduce that “glue” to prevent heart attacks, strokes, or clots on medical devices. For investors this matters because safety, trial results, approvals, and prescribing patterns directly affect demand, market size, and regulatory risk for related drugs and devices.

- Data is from comprehensive review of hospital charges and all-payer claims over five years - 

- Preventable complications such as amputation and conduit infection increased initial hospital charges by approximately $493,000 and $590,000 per patient respectively –

- Humacyte’s Symvess® has consistently demonstrated low rates of infection and high rates of limb salvage –

DURHAM, N.C., Jan. 08, 2026 (GLOBE NEWSWIRE) -- Humacyte, Inc. (Nasdaq: HUMA), a commercial-stage biotechnology platform company developing universally implantable, bioengineered human tissues at commercial scale, today announced the results of a five-year retrospective analysis of hospital charges, payer costs, and healthcare resource utilization in patients with extremity arterial injury. The average hospital charge for extremity arterial injury repair during initial hospitalization was $316,600 per patient, and amputations and infections increased the average hospital charge per patient by $492,986 and $589,921, respectively. Humacyte’s Symvess (acellular tissue engineered vessel) has consistently demonstrated low rates of conduit infection and high rates of limb salvage in the treatment of extremity arterial injury.     

Data from two linked databases (Premier Inc. Healthcare Database and Inovalon all-payer claims database) included hospital charges and reimbursed costs in 964 adult patients with extremity arterial injuries that required surgical repair. Patients undergoing extremity arterial injury repairs using autologous vein, synthetic grafts, and other biological conduits were included, from 2018-2023. All data were collected prior to Food and Drug Administration approval of Symvess for extremity arterial injury repair and so reflect healthcare economics prior to Symvess commercialization. Healthcare costs were analyzed using logit and generalized linear models. 

The extremity arterial injury patient cohort had an average age of 36.5 years, and 26% were treated with conduits other than autologous vein. The average hospital charge for extremity arterial injury repair during initial hospitalization was $316,600, and the average reimbursed cost was $75,947. Preventable complications had enormous impacts on hospital charges, in particular graft infection, amputation, and rhabdomyolysis (severe ischemic damage to muscles). However, incremental reimbursement for these complications was substantially less than the increased hospital charges. Vascular graft infection resulted in an average of $589,921 in additional hospital charges, and the average reimbursed cost was $84,598. Amputation resulted in an average of $492,986 additional hospital charges, and the average reimbursement was $116,611.

Symvess offers an alternative to the high costs of complications from extremity arterial injury that occur when vein is not feasible for repair.  As previously reported in JAMA Surgery, in clinical study Symvess’s rate of infection was one-ninth that of synthetic graft historical controls, and Symvess’s amputation rate was one-fifth that of historical controls.

“This analysis of a real-world population of patients with vascular trauma showed that the high costs often stem not from the initial injury, but rather from preventable complications such as conduit infection, amputation, and rhabdomyolysis. In addition, post-discharge health care resource use was the lowest among the different graft types and remained stable over time for autologous vein-treated patients; for patients treated with other graft types, rates of outpatient, ER visits, and hospital stays were higher at 6 months and further increased through 18 months post-injury,” said Fulton Velez, MD, MS, MBA, Humacyte’s Head of Field Value & Market Access. “For the sizeable number of patients who cannot be repaired using their own vein, Symvess can help reduce these expensive complications and save healthcare dollars while improving patient outcomes.”

Recently published positive three-year results from the V005 Phase 2/3 study of Symvess in extremity arterial injury repair represent the first-ever prospective long-term data in traumatic arterial repair using an off-the-shelf biologic conduit. Extremity arterial injury wounds are challenging for surgeons to treat, and autologous vein grafts have traditionally served as the standard of care due to their durability and low infection rates. However, autologous grafts are not always feasible in trauma settings where veins are damaged or there is little time to harvest - as evidenced by the fact that 26% of reported repairs of such injuries are not performed with vein. Symvess is designed to be immediately available off-the-shelf — saving critical surgical time in emergency situations — and has also consistently demonstrated low rates of infection and high rates of limb salvage.

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.
