Comparison of linaprazan glurate versus lansoprazole for healing of erosive esophagitis in adults with gastroesophageal reflux disease

3 1 1

What is this study about?

This study focuses on treating erosive esophagitis, a condition where the lining of the food pipe becomes damaged due to gastroesophageal reflux disease (GERD). GERD occurs when stomach acid frequently flows back into the tube connecting the mouth and stomach. The study will compare two medications: linaprazan glurate and lansoprazole, which are both drugs that reduce stomach acid production.

The purpose of this research is to determine if linaprazan glurate is more effective than lansoprazole in healing erosive esophagitis. Some participants will receive linaprazan glurate tablets, while others will receive lansoprazole capsules. Some participants will receive placebo. The treatment will continue for up to 8 weeks.

During the study, doctors will examine the healing of the food pipe using a thin, flexible tube with a camera that allows them to see the condition of the esophagus. Participants will also need to keep track of their symptoms, particularly heartburn, using an electronic diary. The study will monitor any side effects that occur during the treatment period.

1 Initial examination and medication assignment

You will undergo an endoscopy examination to confirm the presence of erosive esophagitis (EE), a condition where the esophagus becomes inflamed due to acid reflux.

You will be randomly assigned to receive either linaprazan glurate tablets (50mg) or lansoprazole for treatment.

2 First treatment period

You will take the assigned medication orally for 4 weeks.

During this period, you will need to complete an electronic diary each day to record any heartburn symptoms.

The diary will help track how many days you are free from heartburn symptoms.

3 Week 4 assessment

After 4 weeks of treatment, you will undergo another endoscopy to check if your condition has improved.

The medical team will evaluate the healing of your esophagus.

Your electronic diary entries will be reviewed to assess changes in heartburn symptoms.

4 Extended treatment period

If needed, treatment will continue for an additional 4 weeks (8 weeks total).

You will continue recording daily symptoms in your electronic diary.

5 Final assessment

At week 8, you will have a final endoscopy to evaluate the overall healing of your esophagus.

The medical team will review your complete symptom diary and assess any side effects experienced during the treatment.

Your participation in the study will end after this assessment.

Trial locations

Linaprazan glurate is a new medication being studied for treating erosive esophagitis, a condition where stomach acid damages the esophagus. It belongs to a class of drugs that reduce stomach acid production through a different mechanism than traditional acid-reducing medications.

Lansoprazole is a well-established medication commonly used to reduce stomach acid production. It belongs to a class of medications called proton pump inhibitors (PPIs), which help heal damage to the esophagus caused by acid reflux. It is often used to treat conditions like erosive esophagitis and GERD (gastroesophageal reflux disease).

Erosive Esophagitis (EE) – A condition where stomach acid causes inflammation and damage to the lining of the esophagus, resulting in erosions or ulcers in the esophageal tissue. It occurs as a complication of gastroesophageal reflux disease (GERD), where stomach contents flow back into the esophagus. The condition typically develops gradually, with the esophageal lining becoming increasingly damaged over time. Symptoms include burning pain in the chest, difficulty swallowing, and discomfort when eating.

Gastroesophageal Reflux Disease (GERD) – A digestive disorder that occurs when stomach acid frequently flows back into the esophagus, causing irritation of the esophageal lining. The condition develops due to weakness or improper functioning of the lower esophageal sphincter, which normally prevents stomach contents from moving upward. Common symptoms include heartburn, chest pain, regurgitation of food or sour liquid, and difficulty swallowing. The condition can be chronic, with symptoms occurring regularly over time.
