About this study

Official title: Evaluation of the GORE® ACUSEAL Vascular Graft for Hemodialysis Access (ACUSEAL, AVG 08-06)

This study is a prospective, non-randomized, multi-center evaluation of the performance of the GORE® ACUSEAL Vascular Graft. The study will enroll patients with End-Stage Renal Disease (ESRD), who are either currently receiving or expected to require hemodialysis through a prosthetic vascular graft within 30 days. Gore proposes to demonstrate that the 6 month cumulative patency of the GORE® ACUSEAL Vascular Graft is similar to that of other arteriovenous grafts (AVGs). > >>

>> A total of 138 Subjects will be enrolled. Once the study procedure has been successfully completed, cannulation may occur at any time at the Investigator's discretion. >

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cumulative Patency at 6 Months

    Percentage of subjects free from loss of access for hemodialysis at the study access site, assessed at 6 month.

    Measured: 6 Months

  2. Freedom From Bleeding at 6 Months

    Percentage of subjects free from both major and minor bleeding events, assessed at 6-months

    Measured: 6 Months

Secondary outcomes (4)
  1. Primary Unassisted Patency at 6 Months

    The primary unassisted patency is defined as the percentage of subjects free from the first occurence of either access thrombosis or an access procedure performed to maintain access patency.

    Measured: 6 Months

  2. Time to Event Analysis (Cumulative Patency)

    The cumulative patency at 6 months and time-to-loss of cumulative patency will be estimated using the Kaplan-Meier survival curve for time-to-event analysis to obtain estimates accounting for censoring.

    Measured: 6 Months

  3. Time to First Cannulation

    The time to first cannulation is defined as the time from access placement to the first cannulation of the GORE® ACUSEAL Vascular Graft.

    Measured: Time of access placement to first cannulation, assessed up to one week

  4. Time to Potential Central Venous Catheter Removal

    The time to potential central venous catheter removal is defined as the time from the initial study procedure to the third consecutive cannulation through the GORE® ACUSEAL Vascular Graft in which hemodialysis is carried out. The third consecutive cannulation is a surrogate endpoint for time to CVC removal. Typically, CVC removal is ordered after the third consecutive cannulation.

    Measured: Initial study procedure to the third consecutive cannulation, assessed from day 3 thru day 123

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing GORE® ACUSEAL Vascular Graft in people with End Stage Renal Disease, run by W.L.Gore & Associates.

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 49 inclusion and 0 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 26 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 2 Jul 2013). 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?

Cumulative Patency at 6 Months (time frame: 6 Months). The study lists 2 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 NCT01173718, 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 26 Jul 2013.
