Gastroesophageal reflux disease affects roughly 20% of adults in the U.S., causing heartburn and damage when stomach acid flows back into the esophagus. Most people manage symptoms with proton pump inhibitors like omeprazole or procedures that tighten the valve between stomach and esophagus. Research now focuses on alternatives to daily pills and on people who don't respond to standard treatment.
What's actually going on in research
Trials are testing potassium-competitive acid blockers that work faster than proton pump inhibitors, devices that strengthen the lower esophageal sphincter without surgery, and treatments for refractory reflux that persists despite medication. Studies are also examining the link between reflux and esophageal cancer risk, testing surveillance strategies and drugs that might prevent progression to Barrett's esophagus.
Potassium-competitive acid blockers
Vonoprazan and similar drugs block stomach acid by a different mechanism than proton pump inhibitors. They may work faster and help people whose symptoms don't fully respond to standard treatment.
Endoscopic devices
Several devices can tighten the esophageal sphincter during an outpatient procedure, offering an option between medication and surgery. Studies are comparing them to long-term proton pump inhibitor use.
Barrett's esophagus prevention
Research is testing whether better acid control or ablation of early changes can prevent the progression from chronic reflux to esophageal cancer. Biomarkers may help identify who needs closer monitoring.
What to know before you search
Eligibility typically depends on symptom frequency and severity, response to proton pump inhibitors, presence of Barrett's esophagus or esophagitis on endoscopy, and whether complications like strictures exist.
What types of trials are currently open
- Drug trials — Testing new acid-blocking medications or different dosing strategies for proton pump inhibitors to improve symptom control.
- Device trials — Studies of magnetic beads, radiofrequency ablation, or suturing devices that strengthen the lower esophageal sphincter without major surgery.
- Refractory GERD trials — Testing treatments for people whose reflux persists despite maximum medication, often combining drugs with devices or surgery.
- Prevention trials — Studies examining whether treating reflux early or ablating Barrett's esophagus can prevent esophageal cancer.
- Diagnostic studies — Research on better ways to measure acid exposure, identify who needs treatment, and predict treatment response.
Recently added Gastroesophageal Reflux Disease trials
Receive a new surgical technique to repair your heart valve
The purpose of this study is to assess the safety and effectiveness (usefulness) of an investigational technique used to repair the mitral valve for patients with mitral regurgitation due to a defective valve leaflet. This procedure is called trans-ventricular off-pump mitral valve repair (TRANSOM) and it repairs the mitral valve by replacing some of the cords that support the mitral valve. This type of repair is minimally-invasive since it is performed through a small incision and avoids making a breast-bone-splitting incision.
Receive surgery to repair a hiatal hernia and reduce reflux
This randomized controlled trial compares laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication in patients undergoing surgical treatment for hiatal hernia associated with gastroesophageal reflux disease. Participants will be randomly assigned to one of two surgical groups. The study will evaluate postoperative pain, health-related quality of life, hospital stay, recurrence of reflux symptoms, gas-bloat symptoms, operative time, fundoplication time, and postoperative complications.
