About this study
Official title: Double-Blind Placebo-Controlled Randomized Withdrawal Trial Assessing the Efficacy and Tolerability of "On-Demand" Maintenance Therapy With 10mg o.d. Rabeprazole for 6 Months in Non-Erosive Reflux Disease Patients With Complete Symptom Relief After 4 Week Open Acute Phase
The purpose of this study is to assess the efficacy and safety of long-term, "on-demand" maintenance therapy with rabeprazole in patients with non-erosive reflux disease (NERD).
Read the detailed description
More than half of patients with typical gastroesophageal reflux symptoms such as heartburn are considered to have non-erosive reflux disease (NERD), which is characterized by a lack of clinically defined damage to the esophagus. One approach to maintain control of these symptoms is to have medication available "on-demand." This is a double-blind, placebo-controlled study of the effectiveness of "on-demand" rabeprazole in the long-term maintenance of heartburn control in NERD patients, for whom heartburn was resolved with short-term, daily rabeprazole therapy. The study has two phases: an acute phase (4 weeks) during which patients receive rabeprazole medication daily, and an "on-demand" phase (6 months) during which patients take medication (rabeprazole or placebo) as needed. Only patients who have complete resolution of heartburn at the end of the acute phase are eligible to continue in the "on-demand" phase. Efficacy assessments include the proportion of patients discontinuing treatment in the "on-demand" phase because of insufficient heartburn control, and the severity of heartburn and patient satisfaction determined at the beginning and end of "on-demand" phase. Safety assessments include incidence of adverse events throughout the study, physical examination at study initiation, and vital signs at the beginning and the end of the study. The study hypothesis is that "on-demand" therapy with rabeprazole is superior to placebo in maintaining heartburn control and is well tolerated by the patients with NERD. Rabeprazole tablet (10 milligrams[mg]) once daily in the morning for 4 weeks. Rabeprazole tablets (10mg) once daily on an "on-demand" basis for the following 6 months.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing rabeprazole in people with Gastroesophageal Reflux and Heartburn, run by Janssen Pharmaceutica N.V., Belgium.
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 3 inclusion and 8 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 30 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.
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 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?
Proportion of patients discontinuing treatment in "on-demand" phase (6 months) because of insufficient heartburn control.. 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 NCT00236392, which also lists 1 linked publication.
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 30 Nov 2010.
