Anti-Reflux Endoscopic TX Using APC (AREA) in GERD Patients: (The AREA Study)
(AREA21)
What this study is about
This will be a randomly assigned clinical trial examining the effectiveness 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.
View original scientific description
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.
Interventions
PROCEDURE
ARAT
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.
PROCEDURE
Sham intervention (control)
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.
Primary outcome measures
Change in GERD health related quality of life (GERD-HRQL) score
Time frame: At 3, 6 and 12 months
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
