Pantoprazole Magnesium 40 mg Versus Esomeprazole 40 mg in Patients With Erosive Gastroesophageal Reflux Disease (PAMES 0109)

June 24, 2012 updated by: Takeda

Evaluation of Complete Remission of Erosive Gastroesophageal Reflux Disease Following Four-week Treatment With Pantoprazole Magnesium 40 mg Versus Esomeprazole 40 mg With Eight-week Extension Treatment in Non-responding Patients - Multicenter, National, Prospective, Randomized, Double-blind, Parallel-group, Phase III

The aim of this trial is to evaluate the complete remission of erosive gastroesophageal reflux disease with pantoprazole magnesium 40 mg once daily versus esomeprazole 40 mg once daily during four-week treatment with an extension treatment for non-responding patients. The study includes a baseline period up to 14 days and a treatment period of either 4 weeks (28 -2 + 5 days), or 8 weeks depending on the cure of esophagitis due to gastroesophageal reflux. The study will provide further data on safety and tolerability of pantoprazole magnesium.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparatively evaluation of the clinical efficacy of pantoprazole magnesium and esomeprazole in the treatment of patients with erosive gastroesophageal reflux disease (GERD), considering the proportion of patients in complete remission.
Time Frame: After 4 treatment weeks
A patient is considered at complete remission if he/she achieved symptoms relief and confirmed endoscopic healing at treatment end. A patient achieves symptoms relief if Reflux Questionnaire-GI score ((ReQuest™) stays below 1,73 for at least the three last consecutive treatment days, that can occur at visit V2 or visit V3 for those that did not achieve complete remission at V2 and repeated the treatment for 4 weeks more.
After 4 treatment weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Treatments comparative evaluation for DRGE ReQuest™-GI and -WSO scores change with respect to baseline measured
Time Frame: After 4 and 8 treatment weeks
After 4 and 8 treatment weeks
Treatments comparative evaluation for the time interval from treatment start to the beginning of symptoms relief
Treatments comparative evaluation for endoscopic healing rate
Time Frame: After 4 and 8 treatment weeks
After 4 and 8 treatment weeks
