About this study
Official title: The Effect Of Pantoprazole 40 mg Once Daily Versus Placebo On The Power Spectral Analysis Of The Sleep Electroencephalogram (EEG) Of Patients With Gastroesophageal Reflux Disease (GERD)
The purpose of this research study is to determine if treatment with pantoprazole 40 mg daily versus a placebo improves sleep quality in patients with gastroesophageal reflux disease (GERD). Another purpose is to determine if treatment with pantoprazole 40 mg once daily versus a placebo improves sleep outcomes in patients with gastroesophageal reflux disease using spectral analysis of sleep electroencephalogram (EEG).
Read the detailed description
It appears that the presence of intraesophageal stimuli alone may not be sufficient to elicit symptoms of heartburn. Most acid reflux events (>80%-90%) do not reach conscious level and thus are not perceived.[3] It is yet to be determined what factors enhance our perception of esophageal stimuli and may help to elevate them to the conscious level. In recent years, central and peripheral factors that may enhance our perception of intraesophageal stimuli have been evaluated. Intraduodenal fat infusion was shown to enhance perception of intraesophageal acid in patients with GERD.[4] This study suggested that fat is an important modulator of postprandial GERD symptoms. Central factors, such as stress and psychological comorbidity, also appear to have an important role in symptom generation in patients with GERD, regardless if esophageal inflammation is present or absent.[5-8] Thus, by modulating brain-gut interactions, perception of pathological and probably physiological events in the esophagus of patients with GERD may be altered.
Poor sleep is a central factor that may enhance perception of intraesophageal stimuli and thus elevate them to the conscious level. Several studies have demonstrated that patients with fibromyalgia or irritable bowel syndrome report increased symptoms due to sleep abnormalities.[9, 10] Similar reports in patients with GERD are not available. A subset of patients with GERD experience nocturnal heartburn that may awaken them during the night. In others, despite lack of nocturnal symptoms, sleep abnormalities may occur due to acid reflux events. In both cases, GERD leads to poor sleep, and that in turn may enhance perception of intraesophageal stimuli, leading to reports of increased frequency and severity of perceived GERD symptoms. Thus, poor sleep may be a crucial factor in symptom generation and exacerbation of patients with GERD.
Recently, we have used a novel technique, power spectral analysis of the sleep electroencephalogram (EEG), to assess patients with heartburn and erosive esophagitis and those with heartburn but without erosive esophagitis.[11] We were able to show that among heartburn patients with GERD, EEG spectral power during sleep is shifted towards higher frequencies as compared to heartburn patients without GERD despite similar sleep architecture.
Several recent therapeutic trials in GERD patients have failed to demonstrate improvement in polysomnographic studies despite improvement in GERD-related symptoms and subjective reports of sleep quality.[12] Spectral analysis of the sleep EEG might be a more sensitive tool than polysomnographic study in assessing objective improvement of sleep in patients receiving antireflux treatment.
In summary, sleep disturbances in patients with GERD are poorly recognized and rarely elicited during clinic visits despite their significant impact on patients' quality of life and probably perception of disease severity. Several studies have demonstrated improvement of subjective reports of sleep quality in patients with GERD receiving antireflux treatment. However, the effect of potent antireflux therapy on objective sleep parameters has yet to be demonstrated.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Pantoprazole in people with Gastroesophageal Reflux Disease, run by Southern Arizona VA Health Care 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 4 inclusion and 7 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 19 Aug 2010. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
Symptom control after 4 weeks of treatment. (time frame: April 2008 to July 2010). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00674245, which also lists 6 linked publications.
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 19 Aug 2010; AzTrials last refreshed its copy on 8 Nov 2026.
