Participants who consented were randomized to the HAV treatment arm of one of the two commercially available comparators.
- Conditions
- Renal Failure, End Stage Renal Disease, Hemodialysis, Vascular Access
- Being tested
- Human Acellular Vessel (HAV), ePTFE graft
- Medical subject headings

Measured: 2 to 18 Months post-implantation
Severity of Adverse Events
Severity Assessment Standard
- Mild: Events require minimal or no treatment and do not interfere with the subject's daily activities.
- Moderate: Events result in a low level of inconvenience or concern with the therapeutic measures. May cause some interference with functioning.
- Severe: Events interrupt a subject's usual daily activity and may require systemic drug therapy or other treatment. Severe events are usually incapacitating.
- Life-threatening: Any adverse event that places the subject or participant, in the view of the investigator, at immediate risk of death from the reaction as it occurred, i.e., it does not include a reaction that, had it occurred in a more severe form, might have caused death.
- Death: Death related to Adverse Event.
Measured: 24 months post-implantation

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Human Acellular Vessel (HAV) and ePTFE graft in people with Renal Failure and End Stage Renal Disease, run by Humacyte, Inc. at 38 sites in 6 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 38 sites in United States, Israel, United Kingdom, Poland, Germany and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 30 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Loss of Secondary Patency (time frame: 12 months post-implantation). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02644941, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2026.
