Application Title:
A Human Acellular Vessel in Patients Needing Renal Replacement Therapy: A Comparison with ePTFE Grafts as Conduits for Hemodialysis (HUMANITY)
Public Abstract:
Therapeutic Candidate or Device
Human Acellular Vessel (HAV)
Indication
Conduit for Vascular Access for Hemodialysis
Therapeutic Mechanism
Mechanism of action: the HAV is comprised of intact extracellular matrix constructed by human smooth muscle cells (SMC) in a biomimetic bioreactor system. The manufacturing process is designed to create a biologic matrix similar in protein composition and 3 dimensional structure with biomechanical properties that are observed with native tissue. Once implanted, the HAV is remodeled by the host resulting in a vascular structure more similar in histological appearance to native vascular tissue.
Unmet Medical Need
Current vascular access technologies for hemodialysis are fraught with complications associated with thrombosis, infection and abandonment. Compared to conventional vascular access treatments for dialysis the HAV has the potential for less frequent clotting, abandonment and infection.
Project Objective
Completion of Phase III Clinical Program

Project Objective
Completion of Phase III Clinical Program
Major Proposed Activities
- Manufacturing & Distribution of the HAV for clinical testing in dialysis patients
- Enrollment in Phase III Clinical Trial and Implantation of HAV into patients requiring vascular access for hemodialysis
- Longitudinal test subject follow-up, data collection and analysis, regulatory approval of HAV for widespread clinical use
Statement of Benefit to California:
The research proposed in this application will directly benefit California citizens by advancing medical/surgical therapies in the area of vascular access for hemodialysis. Further, through this clinical program widespread clinical experience will be developed with the HAV for a broader application of vascular reconstruction in all anatomic areas. Finally, this work will economically benefit citizens in California by pursuing clinical research activities and manufacturing processes within CA.
