Radiofrequency ablation	Experimental	Step-wise endoscopic RFA with the Barrx™ Flex Radiofrequency Ablation System using will be performed in 3 month intervals up to 12 months. Receives: Device: Radiofrequency ablation

What is being measured

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

Percentage of Subjects With Complete Response (CR)
The primary endpoint is the percentage of subjects with "complete response (CR)", defined as complete eradication of squamous histological abnormalities (MGIN or worse) within the treatment area (TA) at 12 months after the initial treatment session
Measured: 12 month

Secondary outcomes (3)

Complete Response at Three Months
Number of patients with a CR after primary RFA, defined as absence of MGIN or worse in any of the biopsies from the treatment area at the three months visit
Measured: 3 Months
Complete Response Within the Treatment Area
Number of patients demonstrating complete response within the treatment area (TA), defined as detection of ESCC in biopsy or resection specimen at any time within the first 12 months.
Measured: 3, 6 and 12 Month
Disease Progression Outside the Treatment Area
Proportion of patients demonstrating MGIN or worse outside the TA during treatment phase or follow-up
Measured: Initial, 3, 6, 9 and 12 month

Primary outcome: Percentage of Subjects With Complete Response (CR)

Time frame: 12 month. Count of participants. Unit: Participants

Measure	Radiofrequency Ablation n = 8
Value	8

Population analysed: As the study was terminated early, only 8 subjects completed 12 month follow up.

3 secondary outcomes are reported in the full results.

Adverse events

Time frame: Safety data was evaluated throughout the entirety of follow up, after the study was terminated safety was evaluated for 90 days post RFA procedure.. Other adverse events reported at 0% frequency or more

Group	Serious adverse events	Other adverse events	Deaths
Radiofrequency Ablation	3 of 34 (8.8%)	1 of 34 (2.9%)	0 of 34

Limitations and caveats (from the sponsor): The study was terminated early, therefore there was a limited data set for analysis.

What does the primary outcome measure?

Percentage of Subjects With Complete Response (CR) (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 NCT02953418.

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 12 Aug 2020; AzTrials last refreshed its copy on 27 Oct 2026.
