Trial to Assess the Effectiveness of Maintaining Patency and Safety of the Vascular Wrap Paclitaxel-Eluting Mesh After Surgical Implantation With the Lifespan® ePTFE Vascular Graft in the Upper Extremity for Hemodialysis Vascular Access

Inclusion Criteria:

1. be ≥ 18 years of age;

2. if female of childbearing potential, provide evidence of a negative pregnancy test
within 3 days prior to graft placement (Day -3 to Day 0);

3. be a candidate for a new end-to-side arteriovenous anastomosis graft placed in the
upper extremity;

4. have an outflow vein of greater than or equal to 3 mm in diameter;

5. be able to effectively communicate with study personnel;

6. be considered by the physician to be available for subsequent visits;

7. be willing to comply with all aspects of the treatment and evaluation schedule over a
52 week duration;

8. allow representatives of the sponsor, designated CRO, Institutional Review Board
(IRB), the Ethics Committee, and U.S. Food and Drug Administration (FDA) to review
his/her relevant medical records;

9. sign and date an IRB-approved written informed consent prior to initiation of any
study procedures, including screening procedures;

10. must agree to participate in protocol 014-VWAV07, a safety study to run consecutively
for an additional 4 years or until Post-Market Approval (PMA), whichever is longer;

11. have the Lifespan® ePTFE Vascular Graft successfully implanted.

Exclusion Criteria:

1. pregnant, breast-feeding, or female of childbearing potential who do not agree to
remain abstinent or to use a contraceptive method during the study period.
Non-childbearing potential is defined as either post-menopausal (amenorrheic for at
least 1 year) or surgically sterile. Surgically sterile is defined as tubal ligation
or the absence of the uterus and/or ovaries;

2. male of childbearing potential, who does not agree to remain abstinent or to use
contraception to prevent fathering a child during the course of the study.
Non-childbearing potential is defined as vasectomy or bilateral orchiectomy;

3. a central venous stenosis on the ipsilateral side is documented;

4. a hypercoagulable state is documented;

5. life expectancy is less than one year;

6. an organ transplant is expected within 6 months of test or control product (study
products) placement;

7. hypersensitivity to any component of the study products or procedural materials or
medications is known;

8. concurrently involved in another investigational study;

9. a study product being investigated by others has been received within 30 days prior
to randomization in this trial;

10. the study product being studied in this trial has previously been received;

11. uncontrolled hypertension with systolic BP >200mmHg or diastolic BP >115mmHg is
present at screening;

12. currently receiving chemotherapy or radiation therapy; or

13. placement of a new end-to-end arteriovenous anastomosis graft is required.

Type of Study:


Study Design:

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

Outcome Measure:

Time-to-loss of Target Site Primary Patency

Outcome Description:

Subjects had primary patency at the target site from graft placement until an intervention on the target site occurred. The duration between graft implantation and graft abandonment due to loss of patency at the target site was the "time-to-loss of primary patency." Note: The study was halted early and therefore became underpowered to analyze efficacy as detailed in the protocol.

Outcome Time Frame:

1 year
