About this study
Official title: A Phase III Study to Assess the Efficacy and Safety of NEXIUM for Maintenance of Healing of Erosive Esophagitis in Pediatric Patients 1 to 11 Years of Age
The aim of the study is to compare the safety and efficacy of two doses of Nexium in maintaining healing of erosive esophagitis in patients 1 to 11 years of age.
Read the detailed description
Esomeprazole (NEXIUM™) is indicated for the maintenance of healing of endoscopy-verified erosive esophagitis (EE) in children 1 to 11 years of age in a number of countries worldwide, but not in the United States (US). The current study has been designed, in discussions with the Food and Drug Administration (FDA), to further evaluate the safety and efficacy of NEXIUM given as maintenance of healing of EE in children 1 to 11 years of age
Safety assessments will include the monitoring of adverse events throughout the study, clinical laboratory testing (including hematology, clinical chemistry, urinalysis), vital signs (including blood pressure and pulse), and physical examination including weight.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Nexium 20mg and Nexium 10mg in people with Erosive Esophagitis, run by AstraZeneca at 41 sites in 10 countries.
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 9 inclusion and 10 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 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 41 sites in United States, Portugal, Italy, Argentina, Spain and 5 more countries. 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 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?
Presence / absence of Erosive Esophagitis (time frame: Week 24 (end of 16-week maintenance phase)). 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 13 Oct 2026.
