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.
Potassium-competitive acid blockers
These drugs, including vonoprazan (FDA-approved in 2022), suppress acid faster and more completely than proton pump inhibitors. Trials are testing whether they work better for erosive esophagitis and nighttime reflux.
Minimally invasive procedures
Endoscopic techniques that tighten the valve between stomach and esophagus aim to control reflux without full surgery. Studies compare these approaches to long-term medication use.
Esophageal hypersensitivity
Some people have reflux symptoms without much acid exposure. Trials are testing neuromodulators and behavioral therapies for this group, who often don't respond to acid-blocking drugs.
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.
Recently added Gastroesophageal Reflux Disease trials
Vinegar and Heartburn
In this study, a popular home remedy, vinegar, will be tested for its efficacy to relieve the discomfort of heartburn possibly by inducing the esophageal clearing mechanisms. We plan to recruit 22 individuals who report regular heartburn, but not diagnosed with erosive reflux disease, for this randomized crossover trial. Enrolled participants will identify foods that consistently cause their heartburn, and two of these foods will be prepared and consumed during their visits. Participants will arrive at the testing center on two occasions following a 4-h fast (no food or beverage except water) and consume the targeted foods in a 10-minute period. On one visit liquid vinegar will be ingested with the meal, and on the other visit (order of visits will be randomly determined) a vinegar tablet (control) will be ingested with the meal. Starting prior to food ingestion and for 2 hours post meal, symptoms will be assessed at 10-to-15-minute intervals by the participant using a validated heartburn severity scale.
Efficacy and Safety of K-CAB(Tegoprazan) 25 mg as Maintenance Therapy Following the Treatment of GERD
This study aims to assess heartburn and acid regurgitation symptoms during long-term administration of K-CAB Tab/K-CAB ODT(Tegoprazan) 25 mg in patients with GERD in routine clinical practice. The study will also evaluate safety information, including important potential risks.
