About this study

Official title: A Single-center Trial of Endoscopic Radiofrequency Ablation of Moderate and High-grade Intra-epithelial Squamous Neoplasia and Early Flat-type Squamous Cell Carcinoma Using the HALO Ablation System

Patients with MGIN, HGIN or flat-type early SCCA of the esophagus will be treated on 3 month intervals with Radiofrequency Ablation (RFA) until complete eradication (CR: no MGIN or worse in the biopsies) will be achieved. All patients will undergo an endoscopy at 12 months after baseline, and the patients with CR will undergo annual endoscopy with biopsies for 5 years.

Read the detailed description

A patient population with a histopathological diagnosis of moderate-grade intra-epithelial neoplasia (MGIN), high-grade intra-epithelial neoplasia (HGIN) and/or early flat-type SCCA of the esophagus, in lesions measuring 3 to 12cm in length, will be treated with radiofrequency ablation (RFA) using the HALO ablation system. Additional RFA sessions will be performed on 3 month intervals until complete response (CR; no MGIN or worse in biopsies) will be achieved. All patients will then undergo an endoscopy at 12 months after baseline. Patients with CR at 12 months will be followed-up for 5 years with annual endoscopy and biopsies, and additional treatment if necessary. Patients with no CR at 12 months are considered failures.

What participants receive

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

  • Radiofrequency AblationDevice

    Also called RFA, Barrx ablation system, HALO ablation system

    Patients with a histopathological diagnosis of moderate-grade intra-epithelial neoplasia (MGIN), high-grade intra-epithelial neoplasia (HGIN) and/or early flat-type SCCA of the esophagus, are treated with radiofrequency ablation, with repeat endoscopy and follow-up treatment at 3 month intervals.

What is being measured

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

  1. Complete Response

    The percentage of subjects demonstrating complete response (CR) defined as complete histological clearance of MGIN, HGIN and SCCA in the treatment area at 12 months after the initial ablation procedure

    Measured: 12 Month

Questions about this trial

What is this clinical trial studying?

A study testing Radiofrequency Ablation in people with ESOPHAGEAL SQUAMOUS CELL CARCINOMA, run by Covidien, GI Solutions at 1 site in China.

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 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 21 May 2020. 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 China. 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 21 May 2020). 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?

Complete Response (time frame: 12 Month). 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 NCT02047305, which also lists 3 linked publications.

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 21 May 2020.
