Humacyte, Inc: Humacyte Announces Presentation of Positive Results from V007 Phase 3 AV Access Clinical Trial at the American Society of Nephrology's Kidney Week 2024

- ATEV demonstrated superiority at six and 12 months (co-primary endpoints) compared to autogenous fistula, the current standard of care for hemodialysis access -

- ATEV also showed superior function and patency in female, obese and diabetic patients, subgroups with historically poor outcomes with autogenous fistula procedures -

DURHAM, N.C., Oct. 28, 2024 (GLOBE NEWSWIRE) -- Humacyte, Inc. (Nasdaq: HUMA), a clinical-stage biotechnology platform company developing universally implantable, bioengineered human tissue at commercial scale, announced the presentation of positive results from the V007 Phase 3 clinical trial of the acellular tissue engineered vessel (ATEV) in arteriovenous (AV) access for patients with end-stage renal disease at the American Society of Nephrology's (ASN) Kidney Week 2024, the premier nephrology meeting, in San Diego.

In the Phase 3 trial, the ATEV demonstrated superior function and patency at six and 12 months (co-primary endpoints) compared to autogenous fistula, which is the current standard of care for hemodialysis patients, and also showed superior function and patency in female, obese and diabetic patients, each of which is a high-need subgroup with historically poor outcomes with AV fistula procedures. The late-breaking podium presentation, titled "Prospective Randomized Trial of Humacyte's Acellular Tissue Engineered Vessel Versus Autologous Arteriovenous Fistula for Hemodialysis Access," was presented on Saturday, October 26, 2024 by Mohamad A. Hussain, MD, PhD, RPVI, FAHA, FRCSC, FACS, Vascular and Endovascular Surgeon-Scientist at Brigham and Women's Hospital, Core Faculty at the Center for Surgery and Public Health, and Assistant Professor of Surgery at Harvard Medical School.

"These results show that availability of the ATEV, a biologic conduit, could be game changing in improving arteriovenous access in many hemodialysis patients," said Dr. Hussain. "I was particularly pleased to see positive results in female, obese, and diabetic patients, groups which typically have poor outcomes with autogenous fistula procedures and historically limited treatment alternatives for hemodialysis access. The significantly higher duration of access over one year in these underserved patients could greatly reduce reliance on catheters for arteriovenous access."

The V007 Phase 3 trial (NCT03183245) is a prospective, multi-center, randomized clinical study in 242 hemodialysis patients in the United States. Enrolled individuals were randomly assigned to receive either the ??ATEV or an AV fistula for hemodialysis access and are being followed for up to 24 months. Under the statistical analysis plan for the trial, the primary efficacy assessment compared functional patency (usability for hemodialysis access) at six months and secondary patency (blood flow through the conduit) at 12 months, as co-primary endpoints. At six months, 81.3% of the patients implanted with the ATEV had functional patency compared to 66.4% of the patients receiving an AV fistula. At 12 months, 68.3% of the patients implanted with the ATEV had secondary patency, compared to 62.2% of the patients receiving an AV fistula. The joint test for superiority of the ATEV versus AV fistula at six and 12 months was statistically significant (p=0.0071). Patients receiving an ATEV also achieved a significantly longer duration of hemodialysis over the first 12 months, as compared to AV fistula (p=0.0162).

Sub-group analysis was also performed in patient groups that historically have poor outcomes with AV fistula procedures. In female patients (n=70), patients implanted with the ATEV had significantly higher six-month and one-year patency rates than female patients receiving an AV fistula (p<0.0001). Female patients receiving an ATEV also achieved a significantly longer duration of hemodialysis over the first 12 months compared to AV fistula, 8.3 months versus 5.0 months, respectively (p=0.0011). In obese patients (body mass index or BMI of at least 30) (n=93), patients implanted with the ATEV had significantly higher six-month and one-year patency rates than diabetic patients receiving an AV fistula (p=0.0001). Obese patients receiving an ATEV also achieved a significantly longer duration of hemodialysis over the first 12 months compared to AV fistula, 7.7 months versus 4.5 months, respectively (p=0.0020). In diabetic patients (n=165), patients implanted with the ATEV had significantly higher six-month and one-year patency rates than diabetic patients receiving an AV fistula (p=0.0024). Diabetic patients receiving an ATEV also achieved a significantly longer duration of hemodialysis over the first 12 months compared to AV fistula, 7.4 months versus 5.5 months, respectively (p=0.0155).

Rates of infection were low in both treatment arms, with 9.1% of patients implanted with the ATEV experiencing access-related infections (12 total events) compared to 9.9% of patients treated with AV fistula (14 total events). Treatment-Emergent Adverse Events (TAEEs) occurred in 98.3% of patients implanted with the ATEV (1,211 total events) compared to 96.7% of patients treated with AV fistula (828 total events). The largest area of difference in adverse events was in thrombosis, occurring in 52.1% of patients implanted with the ATEV (126 total events) compared to 9.1% of patients treated with AV fistula (12 total events). The majority of ATEV patients with thrombosis, 94%, were successfully treated.

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. Humacyte develops and manufactures acellular tissues to treat a wide range of diseases, injuries, and chronic conditions. Humacyte's initial product candidates, a portfolio of 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 is currently under review by the FDA and was granted Priority Review. 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 www.Humacyte.com.
