Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, multicenter, multi cohort, non-randomized phase 2/3 study in adult patients with life or limb threatening vascular trauma which requires surgical repair.

There will be an extremity cohort and a torso cohort. The extremity cohort will include patients who require repair of a vessel contained to the upper or lower extremity. The torso cohort includes patients who require repair of vessels within the thorax (excluding the heart), abdomen, and retroperitoneum. Subjects will be implanted with an ATEV as an interposition vessel or bypass using standard vascular surgical techniques. There is no control arm.

The active study duration for each study participant will be 36 months from implantation or until ATEV failure/ removal/ death, if earlier. Follow up after month 12 will involve the capture of information on assessments performed at "standard of care" routine clinic visits or by telephone follow up with the patient or his/her physician with physical exam and ultrasound at month 24 and month 36.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

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 6 mm Acellular Tissue Engineered Vessel (ATEV) 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

    • 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)
  • ATEV 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 ATEV
  • Previous exposure to ATEV
  • 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

  • Human Acellular Vessel (HAV)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Time Frame: 30 days from time of implantation
Rate of primary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.
30 days from time of implantation
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the Extremity Community-Acquired Trauma Subgroup
Time Frame: 30 days from time implantation
Rate of primary patency at 30 days post-implantation, evaluated strictly within the sub-cohort of participants presenting with non-iatrogenic, community-acquired extremity vascular trauma. Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the 30-day evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.
30 days from time implantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Secondary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Time Frame: 30 days from time of implantation
Rate of secondary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Secondary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, including vessels that became occluded but were successfully restored to patency via intervening endovascular or surgical re-intervention (e.g., thrombectomy, thrombolysis, or patch angioplasty).
30 days from time of implantation
