Study summary

The goal of this clinical trial is to compare the number of catheter-free days (CFD) and the rate and severity of any dialysis access-related infections between the ATEV and AVF groups over 12 months in patients with end-stage renal disease (ESRD) needing hemodialysis (HD).

Participants will be stratified by location of the vascular access (forearm versus upper arm) and by type of AVF creation procedure planned by the surgeon at randomization (1-stage AVF versus 2-stage AVF). The comparator is an upper extremity arterio-venous fistula (AVF) for HD access surgically created per the institution's Standard of Care (SoC).

Read the detailed description

This is a prospective, multicenter, randomized, two-arm, comparative Phase 3 study of female patients with ESRD, who are receiving clinically successful hemodialysis (HD) via a central venous dialysis catheter (DC).

Approximately 150 female patients will be randomized 1:1 to either the ATEV or the AVF treatment arm. Patients will be stratified by location of the vascular access (forearm versus upper arm) and by type of AVF creation procedure planned by the surgeon at randomization (1-stage AVF versus 2-stage AVF).

All patients will be followed through Month 12 regardless of SA patency status. Patients who have a patent SA at Month 12 will then be followed in the Long-Term Extension study for an additional 12 months with evaluation of exploratory long-term endpoints.

Inclusion criteria

  1. Female patients with ESRD, currently receiving hemodialysis via dialysis catheter and who are candidates for the creation of an AVF (see Inclusion Criterion #4 below) or implantation of an ATEV for HD access.
  2. Patients who plan to undergo HD at a dialysis unit of a participating dialysis provider for at least 12 months after SA creation.
  3. Patients aged ≥ 18 years at Screening.
  4. Suitable anatomy for creation of a forearm or upper arm AVF and for implantation of straight, curved, or looped ATEV in either the forearm or upper arm.

    NOTE: Suitable anatomy will be determined by both physical examination and ultrasound imaging or vessel imaging modality in addition to consideration of all vascular sites available, prior access failure, future access sites and possibilities to preserve patients' future alternate accesses. Vessel mapping is the preferred method to assess the vascular anatomy, and will evaluate the following attributes during Screening:

    • Vein diameter
    • Arterial diameter
    • Presence of arterial calcification
    • Depth of the intended fistula conduit from the surface of the skin
    • Central vein patency
    • Previous vascular access location The ultimate decision of anatomic suitability belongs to the surgeon and/or the investigator.
  5. ≥ 7 g/dL and count ≥ 100,000 /mm3
  6. Patients must either:

    1. Be of non-, which is defined as (at least 1 year without menses prior to Screening) or documented surgically sterile (i.e., total hysterectomy or tubal ligation, or complete bilateral oophorectomy) at least 1 month prior to Screening.
    2. Or, if of childbearing potential:

    Must have a negative serum pregnancy test at Screening, and

    Must agree to use at least one form of the following methods for the duration of the study:

    i. Established use of oral, injectable or implanted hormonal methods of contraception.

    ii. Placement of an intrauterine device or intrauterine system at least 5 days prior to Screening.

    iii. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/ gel/ film/ cream/ suppository.

  7. Patient or their legal representative can communicate effectively with investigative staff, is competent and willing to give written , and able to comply with entire study procedures including all scheduled follow-up visits.
  8. of at least 1 year confirmed by Charlson Comorbidity Index ≤ 9.

  3. Known serious allergy or intolerance to aspirin and alternative antiplatelet therapy.
  4. Pregnancy, or women intending to become pregnant during the course of the trial.
  5. Treatment with any drug or device within 60 days or 5 half-lives after taking the last dose (whichever is longer) prior to study entry (Day 1) or ongoing participation in a clinical trial of an investigational product.

  13. Employees of Humacyte and employees or relatives of an investigator.
Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 26, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
