About this study
Official title: Anti-Reflux Endoscopic Therapy Using Argon Plasma Coagulation (AREA) in Gastroesophageal Reflux Disease (GERD) Patients: A Single Center, Randomized, Sham, Controlled Trial (The AREA Study)
This will be a randomized clinical trial examining the efficacy and safety of ARAT (intervention group) in patients with chronic GERD symptoms (typical symptoms of GERD, i.e. heartburn or acid reflux/regurgitation at least twice a week) for the last 6 months.
Patients must have a positive pH test and a negative manometry (no treatment) procedure.
- Conditions
- Gastro Esophageal Reflux
- Being tested
- ARAT, Sham intervention (control)
- Medical subject headings
- Gastroesophageal Reflux
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ARATProcedure or surgery
Also called Anti-reflux mucosal ablation
For patients randomized to ARAT intervention, the area of cardia, along greater curvature will be cleaned followed by demarcation of a 1-1.5 cm area of non-ablation zone with two vertical lines by use of Pulsed APC (30W, Effect 2) using the H-APC catheter. Next, the area of cardia, on either side will be injected in sequence using a methylene blue (0.5%) and normal saline (0.9%) using the H-APC catheter jet system (Effect 30-70). Next, the mucosa, starting below the z-line and up to 3 cm below will be treated by Pulsed APC 50W-80W till golden-brown discoloration of the ablated tissue in 270-320 degree. For patients randomized to control or sham intervention, upper endoscopy with procedural sedation was performed followed by markings of landmarks followed by gastroscope retroflexion in the gastric cardia with at least 15 minute of examination time. No H-APC or submucosal injection or other intervention will be performed.
Sham intervention (control)Procedure or surgery
Patients randomized to the control arm, will undergo a sham intervention. This will include performing upper endoscopy with procedural sedation followed by markings of landmarks as described. This will be followed by gastroscope retroflexion in the gastric cardia with at least 15 minute of examination time spent in retroflexion to reciprocate the H-APC intervention. No H-APC or submucosal injection or other intervention will be performed during the upper endoscopy with sham intervention. All Patients will also continue their PPI daily for 4 weeks.
| Study group | Role | What they receive |
|---|---|---|
| Anti-reflux mucosal ablation (ARAT) | Active comparator | ablation in the gastric cardia using hybrid argon plasma coagulation Receives: Procedure: ARAT |
| No treatment | Sham comparator | no ablation Receives: Procedure: Sham intervention (control) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in GERD health related quality of life (GERD-HRQL) score
The primary outcome of quality of life will be measured using the validated GERD related quality of life questionnaire (GERD-HRQL). The total score is 50, and a higher score is associated with more severe symptoms.
Measured: At 3, 6 and 12 months
Secondary outcomes (6)
Change in Reflux disease questionnaire (RDQ) score
RDQ scores will be assessed using a validated questionnaire scale. The total score is 40, and a higher score is associated with more severe symptoms.
Measured: At 3, 6 and 12 months
Change in Proton pump inhibitor (PPI) use
Frequency of PPI medication use
Measured: At 3, 6 and 12 months
Acid exposure time (AET)
Ambulatory acid reflux testing (wireless pH monitoring system) for measurement. Acid exposure time measures amount of time spent in pH <4. A time >4% is considered positive for acid reflux.
Measured: At 3 and 12 months
Adverse events
Frequency of any adverse event including chest pain, bleeding, dysphagia, hospitalization
Measured: Post-randomization (Day 1, Day 30, 3rd, 6th and 12th month)
Change in Hiatal hernia grading
Hill grade for hiatal hernia assessment during endoscopy. There are 4 grades: I, II, III and IV depending on the appearance of the hiatus on endoscopy.
Measured: At 3 and 12 months
Esophagitis incidence
LA grade esophagitis at the time of endoscopy
Measured: At 3 and 12 months

Questions about this trial
What is this clinical trial studying?
A study testing ARAT in people with Gastro Esophageal Reflux, run by Midwest Veterans' Biomedical Research Foundation 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 11 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: looking for participants now, as of the sponsor's last update on 27 Feb 2026. 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. Some participants in this study may receive a placebo. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact April Higbee, BSN (816-861-4700, april.higbee@va.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in GERD health related quality of life (GERD-HRQL) score (time frame: At 3, 6 and 12 months). 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 NCT05570448, which also lists 19 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 27 Feb 2026.
