What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if linaprazan glurate is more effective than the commonly used drug lansoprazole in healing and reducing symptoms of erosive esophagitis (damage to the esophagus) caused by GERD. Researchers will assess the safety of linaprazan glurate, its impact on heartburn, and whether its effectiveness varies with blood concentration or participants' genes. Individuals with confirmed esophageal damage from GERD, who have not recently received treatment for Helicobacter pylori infection, may be suitable for this study. Participants will take medication daily for up to 8 weeks and undergo regular health checks, including endoscopies and symptom questionnaires. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the opportunity to contribute to potentially groundbreaking treatment advancements.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, you cannot participate if you've taken antibiotics or bismuth-containing drugs in the past 6 weeks, or if you've been treated with lansoprazole within 2 months before the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that linaprazan glurate is generally safe. In earlier studies, patients tolerated it well and experienced high healing rates after four weeks of treatment. These studies suggest that linaprazan glurate is usually well-tolerated, with few side effects reported, indicating it may be safe to use.

Lansoprazole, already approved for treating acid reflux, is also known for its safety. It has been used for many years, and its side effects are well-known and usually mild.

In this trial, both treatments aim to reduce heartburn symptoms and heal damage to the esophagus. Evidence supports the safety of both linaprazan glurate and lansoprazole for treating acid reflux. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Linaprazan Glurate because it offers a potential new approach to treating acid reflux. Unlike standard treatments like lansoprazole, which primarily block acid production, Linaprazan Glurate works by targeting stomach acid secretion differently. This new mechanism could mean more effective relief for patients who don’t respond well to existing proton pump inhibitors (PPIs). Additionally, the flexibility in dosing—either once or twice daily—may improve patient adherence and convenience.

What evidence suggests that this trial's treatments could be effective for GERD?

This trial will compare Linaprazan Glurate with Lansoprazole for treating acid reflux. Studies have shown that Linaprazan Glurate, which participants in this trial may receive, effectively heals erosive esophagitis, a condition caused by GERD. One study found that 80% of patients who took Linaprazan Glurate experienced improvement, compared to 69% of those who took Lansoprazole, another treatment option in this trial. This suggests that Linaprazan Glurate might be more effective at healing the esophagus. Additionally, Linaprazan Glurate is generally well-tolerated, meaning it usually doesn't cause serious side effects. However, it hasn't always been more effective than other treatments when used long-term. Overall, early research is promising for Linaprazan Glurate, especially for short-term use. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-80 with erosive esophagitis due to GERD, confirmed by endoscopy. It's not suitable for those with active Helicobacter pylori infection, recent HP treatment, or recent use of antibiotics or bismuth drugs.

What Are the Treatments Tested in This Trial?

Interventions

• Lansoprazole
• Linaprazan Glurate

Trial Overview

The study compares the effectiveness and safety of linaprazan glurate (50 mg once or twice daily) against lansoprazole (30 mg daily) in healing EE from GERD. It's a randomized, double-blind trial where neither participants nor researchers know who receives which treatment.

How Is the Trial Designed?

Group I: Group 2: Linaprazan glurate 50 mg QD Experimental Treatment 1 Intervention

Group II: Group 1: Linaprazan glurate 50 mg BID Experimental Treatment 1 Intervention

Group III: Group 3: Lansoprazole 30 mg QD Active Control 1 Intervention
