About this study

Official title: HALO Patient Registry: Ablation of Barrett's Esophagus, A Multi-Center Patient Registry

The HALO Patient Registry is a prospective/retrospective, multi-center patient registry. It provides a framework for treatment and follow-up of patients with Barrett's esophagus (non-dysplastic IM, LGD and HGD). The primary objective is to provide a tool for participating physician investigators to collect outcomes data related to the use of the HALO Ablation Systems.

Read the detailed description

Summary The HALO Patient Registry provides a framework for treatment and follow-up of patients with Barrett's esophagus (non-dysplastic IM, LGD and HGD). The primary objective is to provide a tool for participating physician investigators to collect outcomes data related to the use of the HALO Ablation Systems.

Protocol Design:

This is a prospective, multi-center patient Registry. Sites may choose to also retrospectively enroll previously treated patients (after obtaining informed consent) and enter retrospective data into case report forms on-line. "Retrospective data collection" is defined as any data other than patient history collected prior to signing of the informed consent. A set of case report forms (CRFs) is provided along with this protocol to track outcomes. The CRFs may be completed and retained on site, but the site is recommended to utilize the internet-based data entry system.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radiofrequency Ablation (HALO Ablation Systems)Device

    Also called HALO 90, HALO 360

    Subjects undergo ablation procedures (circumferential or focal) plus standard anti-secretory drug therapy (proton pump inhibitor, PPI). All Patients undergo endoscopy with biopsy in a Physician prescribed surveillance pattern after a negative biopsy.

What is being measured

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

  1. Endoscopic Clearance Rate for Barrett's Esophagus-Percentage of Patients With no Endoscopically Visible Barrett's Esophagus at 1 Year Follow-up

    % of patients with 100 % resolution at 1 year follow-up. This endpoint is a visual and not reliable or accurate. A better measure of clearance of Barrett's esophagus is based on biopsies.

    Measured: 1 year

  2. Histological Clearance Rate for Intestinal Metaplasia (CE-IM)

    Percentage of patients with no histological evidence of intestinal metaplasia at 1 year follow-up

    Measured: 1 year

  3. Histological Clearance Rate for Dysplasia (CE-D)

    percentage of patients with baseline dysplasia who have no histological evidence of dysplasia at 1 year follow-up

    Measured: 1 year

  4. Percentage of Patients With Sub-squamous Intestinal Metaplasia at 1 Year Follow up

    Percentage of patients at 1 year follow-up with sub-squamous intestinal metaplasia, with or without dysplasia, that is covered completely by an intact layer of squamous epithelium with no communication with the surface

    Measured: 1 year

  5. Patient Quality of Life Questionnaire Results: Change From Baseline to 12 Month

    Patient who completed both baseline and follow-up Quality of Life: Scores (0-10) of quality of life at baseline and 12 month follow-up were measured and changes were calculated ( 12 months minus baseline) in: concerns about the condition of esophagus, negative impact on life and esophageal cancer worry. Scale range is 0-10, 0 is min and 10 is max. Higher value represent worse outcome (such as higher concern about the condition of esophagus, negative impact on life and higher esophageal cancer worry).

    Measured: 12 month

  6. Adverse Event Incidence

    Adverse and Serious Adverse event with Definite device relationship

    Measured: 12 month

Questions about this trial

What is this clinical trial studying?

A study testing Radiofrequency Ablation (HALO Ablation Systems) in people with Barrett Esophagus, run by Medtronic - MITG at 1 site in United States.

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 2 inclusion and 4 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 5 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Feb 2016). 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?

Endoscopic Clearance Rate for Barrett's Esophagus-Percentage of Patients With no Endoscopically Visible Barrett's Esophagus at 1 Year Follow-up (time frame: 1 year). The study lists 6 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 NCT00848237, 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 5 Feb 2016.
