About this study

Official title: Comparison of the Nighttime Effects of Rabeprazole 20 mg to Pantoprazole 40 mg on Standard Meal Stimulated Gastric Acid Secretion and Intragastric pH in H. Pylori Negative Volunteer Subjects With GERD

The purpose of the study is to compare the effect of two different drugs, rabeprazole (20 mg) and pantoprazole (40 mg), and their effects on the amount of acid produced by your stomach on evening and at night after standard protein meal.

Read the detailed description

Gastric acid secretion can be divided into two phases: the daytime phase and the nocturnal phase. Nocturnal acid reflux is presumably more damaging because of loss of salivary neutralization. The present study is designed to measure effects of rabeprazole and pantoprazole on post-prandial and nocturnal gastric acid secretion and intragastric pH in H. pylori-negative volunteers with gastroesophageal reflux disease. These measurement will be used to compare the degree of inhibition of gastric acid secretion between the two drugs.

Being tested
rabeprazole, pantoprazole
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rabeprazoleDrug

  • pantoprazoleDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To test the hypothesis that during the hours 2000 through 0800 following a single dose administration of medication, the median change from baseline values in gastric acid secretion with 20 mg rabeprazole is significantly less than 40 mg pantoprazole

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing rabeprazole and pantoprazole in people with Gastroesophageal Reflux Disease, run by VA Greater Los Angeles Healthcare System at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Sep 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To test the hypothesis that during the hours 2000 through 0800 following a single dose administration of medication, the median change from baseline values in gastric acid secretion with 20 mg rabeprazole is significantly less than 40 mg pantoprazole. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Sep 2007.
