  Purpose

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.

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
  • Histological clearance rate for intestinal metaplasia--Percentage of patients with no histological evidence of intestinal metaplasia at 1 year follow-up [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Histological clearance rate for dysplasia--percentage of patients with baseline dysplasia who have no histological evidence of dysplasia at 1 year follow-up [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Sub-squamous intestinal metaplasia--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 [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Patient quality of life questionnaire results comparing baseline versus 12 month [ Time Frame: 12 month ] [ Designated as safety issue: No ]
  • Adverse event incidence [ Time Frame: 12 month ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 10000
Study Start Date: July 2007
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment
All Patients with Barrett's esophagus or Intestinal metaplasia which is visible endoscopically or histologically may be treated with the Radiofrequency ablation system.
 Device: Radiofrequency Ablation (HALO Ablation Systems)
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.
Other Names:
  • HALO 90
  • HALO 360

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.
