What is being measured
The primary outcome is the main question the study is designed to answer.
To compare rates of remission (non re-appearance of erosive esomeprazole) when treated with esomeprazole or lansoprazole; in patients in with erosive esomeprazole (EE) that is in remission (i.e. previously healed EE).
Measured: Symptoms will be assessed by the investigator at each visit and the patients will undergo an endoscopy at Months 3 and 6
Secondary outcomes (3)
To compare endoscopic remission rates through 6 months of treatment with E20 and L15, after initial healing of EE.
Measured: Symptoms will be assessed by the investigator at each visit and the patients will undergo an endoscopy at Months 3 and 6
The assessment of symptoms in the two treatment groups after 1, 3 and 6 months.
Measured: patients will undergo an endoscopy at Months 3 and 6
To assess the safety and tolerability of up to 6 months of treatment with E20 and L15 after initial healing of EE.
Measured: Symptoms will be assessed by the investigator at each visit and the patients will undergo an endoscopy at Months 3 and 6

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Esomeprazole and Lansoprazole in people with Erosive Esophagitis, run by AstraZeneca.
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 2 inclusion and 3 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 26 Mar 2009. 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 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 compare rates of remission (non re-appearance of erosive esomeprazole) when treated with esomeprazole or lansoprazole; in patients in with erosive esomeprazole (EE) that is in remission (i.e. previously healed EE). (time frame: Symptoms will be assessed by the investigator at each visit and the patients will undergo an endoscopy at Months 3 and 6). 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 26 Mar 2009.
