Co-primary endpoint #1: Proportion of subjects with functional patency at 6 months post study access (SA) creation The definition of "functional patency" is: Dialysis with "2 needles for ≥75% of dialysis sessions over a continuous 4-week period and either: (1) 4 consecutive sessions during the 4-week period in which 2 needles are used and the mean dialysis machine blood pump speed is ≥300 mL/min, or (2) a measured spKt/Vurea is ≥ 1.4 or urea reduction ratio \>70% during any session in which 2 needles are used within the 4-week period. SpKt/Vurea is calculated from pre and post-treatment serum urea nitrogen concentrations, body weight, and dialysis session duration." The functional patency ascertainment period will take place between the 1st day of Week 21 (Day 140) and the last day of Week 26 (Day 181) after AVF creation or HAV placement. The endpoint is met when the functional patency criteria are satisfied within any consecutive 4 week period within this ascertainment period.
Co-primary endpoint #2: Proportion of subjects with secondary patency of SA at 12 months post SA creation. The SA maintains secondary patency until it is abandoned, irrespective of interventions to maintain or restore patency. Abandonment is defined as AVF or HAV that can no longer be used for 2-needle, prescribed dialysis as it may be unable to provide adequate flows and/or is deemed unsafe for the subject, and the associated problem cannot be corrected by any intervention, including medical, surgical, or radiological interventions or rest.
1. Defined as 'the interval from the time of access placement until access abandonment', i.e., patent with or without interventions (Sidawy et al. 2002). 2. "Abandonment" defined as no remaining segment of the study conduit was incorporated into the vascular access circuit used for dialysis (conversely, if some portion of the study conduit was still being used for dialysis it was not considered abandoned).
Primary patency = patent ("open" to blood flow) without any interventions; Primary-assisted patency = patent without an intervention to clear a thrombus; Secondary patency = patent with or without interventions

| Arteriovenous fistula (AVF) | PROCEDURE | Surgical creation of an autologous arteriovenous fistula and subsequent use of the implanted vascular conduit for hemodialysis vascular access. |
| Hemodialysis | OTHER | Procedure that filters a person's blood when their kidneys are no longer functioning properly |
| ePTFE graft | DEVICE | One of two commercially available comparators (Bard Impra® and Gore PROPATEN®) |
Inclusion Criteria: 1. Subjects with end-stage renal disease (ESRD), receiving HD via DC and are suitable for the creation of an AVF or implantation of AVG for HD access. 2. Subjects who plan to undergo HD at a dialysis unit of a participating dialysis provider for at least the first 6 months after...
Human Acellular Vessel is an investigational vascular conduit being studied for use in Peripheral Artery Disease and Renal Failure, specifically as a conduit for hemodialysis access in patients with end stage renal disease. It is developed by Humacyte, Inc. (NASDAQ: HUMA) and is currently in clinical development.
Human Acellular Vessel is a monoclonal antibody modality designed to serve as a vascular graft. It is being evaluated as an alternative to synthetic grafts or fistulas for hemodialysis access and for femoro-popliteal bypass in peripheral artery disease. The vessel is intended to provide a biocompatible conduit for blood flow.
Human Acellular Vessel is developed by Humacyte, Inc., a biotechnology company traded on NASDAQ under the ticker symbol HUMA. The company is conducting clinical trials to evaluate the vessel for hemodialysis access and peripheral artery disease treatment.
Human Acellular Vessel is in Phase 2 clinical development for Peripheral Artery Disease, with completed Phase 3 trials for hemodialysis access in renal failure. It has received FDA designations including Regenerative Medicine Advanced Therapy (RMAT) and Priority Review, but it remains investigational and is not yet approved.
Human Acellular Vessel has completed three clinical trials: NCT02644941, a Phase 3 study comparing it with ePTFE grafts for hemodialysis in 355 patients; NCT02887859, a Phase 2 study for femoro-popliteal bypass in 15 patients with peripheral artery disease; and NCT03183245, a Phase 3 study comparing it with fistulas for hemodialysis in 242 patients.
Yes, Human Acellular Vessel is commonly referred to as HAV in clinical trial titles and medical literature. The abbreviation HAV is used in studies such as NCT02644941 and NCT03183245, which evaluate the vessel as a conduit for hemodialysis access.
