Humacyte’s Human Acellular Vessel for Vascular Replacement or Reconstruction in Patients with Life or Limb-threatening Vascular Trauma

Overview

About this study

The purpose of this study is to evaluate the safety and tolerability of the Humacyte HAV in vascular trauma patients undergoing surgery for vascular replacement or reconstruction and to determine the rate of primary patency at 30 days.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Patients with life or limb threatening traumatic injury to an arterial vessel in the limb or torso, other than the heart, which requires replacement or reconstruction.
  • Preoperative imaging or clinical examination indicates the damaged vessel has a defect length of ≤ 38cm and is appropriately size matched to the 6mm Human Acellular Vessel (HAV) per the judgment of the treating surgeon taking into account vasoconstriction and situational inflow and outflow considerations.
  • Autologous vein graft is either not feasible in the judgment of the treating surgeon (e.g., because of lack of availability of suitable conduit, presence of severe venous insufficiency) or is not desirable because of the urgency of revascularization.
  • Aged 18 to 85 years old, inclusive.
  • Able to communicate meaningfully with investigative staff, and able to comply with entire study procedures. If the patient is unconscious, then information from a reliable witness indicates that the patient would normally be able to comply with study procedures.
  • Patient or relative is able, willing and competent to give informed consent.
  • Life expectancy of at least 1 year.

Exclusion Criteria:

  • Mangled Extremity Severity Score (MESS) of ≥ 7.
  • Limb at high risk of amputation despite vascular reconstruction (e.g., because of crush injury).
  • Catastrophic injuries that make survival unlikely (e.g., Abbreviated Injury Scale (AIS) > 5 or Injury Severity Score (ISS) > 60).
  • HAV may not be used for coronary artery repair.
  • Known pregnant women.
  • Known medical condition which would preclude long term antiplatelet therapy after resolution of acute injuries.
  • Any other condition which in the judgment of the investigator would preclude adequate evaluation of the safety and efficacy of the HAV.
  • Previous exposure to HAV.
  • Known participation in any investigational study within the last 30 days.
  • Employees of the sponsor or patients who are employees or relatives of the investigator.

Eligibility last updated 3/22/22. Questions regarding updates should be directed to the study team contact.
