New Treatments & Clinical Trials for Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) affects roughly 20% of adults in the U.S., causing heartburn when stomach acid flows back into the esophagus. Most people manage symptoms with over-the-counter antacids or proton pump inhibitors, but chronic GERD can lead to esophageal damage, Barrett's esophagus, or strictures. Surgery remains an option when medications fail.

What's actually going on in research

Trials are testing potassium-competitive acid blockers that work faster than proton pump inhibitors, minimally invasive procedures that tighten the lower esophageal sphincter, reflux sensors that guide treatment, and drugs targeting esophageal hypersensitivity. Researchers are also studying the microbiome's role in GERD and whether certain probiotics reduce symptoms.

What to know before you search

Eligibility typically depends on symptom frequency, severity of esophageal damage, response to proton pump inhibitors, and whether you have complications like Barrett's esophagus.

What types of trials are currently open

• Medication trials — Testing new acid-blocking drugs or comparing them to proton pump inhibitors to see which controls symptoms and heals esophageal damage better.
• Procedure trials — Studies of endoscopic or surgical techniques to strengthen the lower esophageal sphincter and reduce reflux.
• Device trials — Testing implants or magnetic devices placed around the esophagus to prevent acid from flowing back up.
• Symptom management trials — Testing treatments for people whose GERD symptoms persist despite acid suppression, often targeting nerve sensitivity.
• Prevention trials — Studies of lifestyle changes, weight loss programs, or medications to prevent GERD complications like Barrett's esophagus.
