– Four unique ICD-10-PCS codes, effective October 1, 2024, for replacement of arteries in the upper and lower extremities using Humacyte’s HAV – – BLA submission under Priority Review by FDA for the treatment of vascular trauma, supported by Phase 2/3 clinical trial results and real-world use treating wartime trauma injuries in Ukraine – DURHAM, N.C., June 17, 2024 (GLOBE NEWSWIRE) — Humacyte, Inc. (Nasdaq: HUMA), a clinical-stage biotechnology platform company developing universally implantable, Human Acellular Vessels (HAVs) at commercial scale, today announced the issuance of four new ICD-10-PCS codes by the U.S. Centers for Medicare & Medicaid Services (CMS) ICD-10 Coordination and Maintenance (C&M) Committee. These codes, effective for hospital discharges beginning October 1, 2024, cover procedures for replacing arteries in the upper or lower extremities using Humacyte’s HAV. Humacyte also announced that, based on guidance from the Food and Drug Administration (FDA), the common (non-brand) name for the HAV will be the “acellular tissue engineered vessel” (ATEV). The CMS ICD-10 C&M Committee issues ICD-10-PCS codes to facilitate accurate classification and tracking of procedures. The ICD-10-PCS is a classification for procedures performed during inpatient hospital admissions1. The codes are widely used by hospitals and insurers to support data collection, payment, and monitoring. Obtaining these codes marks a significant milestone as Humacyte advances toward submission of a New Technology Add-on Payment (NTAP) application to CMS planned for later in 2024. Obtaining an ICD-10-PCS code is necessary to file an NTAP application. The newly issued codes are: X2R50WA: Replacement of Right Upper Extremity Artery using Bioengineered Human Acellular Vessel, Open Approach, New Technology Group 10 X2R60WA: Replacement of Left Upper Extremity Artery using Bioengineered Human Acellular Vessel, Open Approach, New Technology Group 10 X2R70WA: Replacement of Right Lower Extremity Artery using Bioengineered Human Acellular Vessel, Open Approach, New Technology Group 10 X2R80WA: Replacement of Left Lower Extremity Artery using Bioengineered Human Acellular Vessel, Open Approach, New Technology Group 10 The ATEV is designed for urgent arterial repair following extremity vascular trauma when synthetic graft is not indicated, and when autologous vein use is not feasible. ATEVs, which are bioengineered human tissues, are under investigation as universally implantable vascular replacements that resist infection and do not require immune suppression. The ATEV is intended to be readily available – “off-the-shelf” – with the potential to save valuable time for surgeons, thereby improving patient outcomes and reducing complications. Humacyte has extensive experience with the ATEV, accumulating over 1,200 patient-years of worldwide use in clinical trials for vascular trauma repair, arteriovenous access for hemodialysis, and peripheral artery disease. The company’s manufacturing facilities are capable of producing ATEVs at commercial scale to meet the potential needs of thousands of patients. The Prescription Drug User Fee Act (PDUFA) date for the FDA’s regulatory decision on Humacyte’s Biologics License Application (BLA), is August 10, 2024. This is based on a Priority Review which was granted by the FDA. The BLA submission was supported by positive results from the V005 Phase 2/3 clinical trial, and real-world evidence from the treatment of wartime injuries in Ukraine. In these studies, Humacyte’s ATEV demonstrated higher patency (blood flow) rates and lower amputation and infection rates as compared to historic synthetic graft benchmarks. 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 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. 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 RMAT designation and has also received FDA Fast Track designation. Humacyte’s 6mm ATEV for urgent arterial repair following extremity vascular trauma also has received an RMAT designation. 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.
