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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Percentage of symptom-free days of heartburn symptoms
Time Frame: Week 4
Heartburn symptoms will be collected by participant diaries.
Week 4
Cumulative symptom improvement rate of heartburn symptoms
Time Frame: Week 4
Heartburn symptoms will be collected by participant diaries.
Week 4
Severity of heartburn symptoms
Time Frame: Week 4
Heartburn symptoms will be collected by participant diaries.
Week 4

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
Measure Description
Time Frame
Heartburn symptoms stratified by response (improvement or non-improvement) at Week 2
Time Frame: Week 4
Heartburn symptoms will be collected by participant diaries. Percentage of symptom-free days, cumulative symptom improvement rate, and severity of heartburn symptoms are evaluation parameters.
Week 4
Heartburn Symptoms Stratified by Baseline Endoscopic Findings (Grade N or M)
Time Frame: Week 4
Heartburn symptoms collected by participant diaries. Percentage of symptom-free days, cumulative symptom improvement rate and severity of heartburn symptoms=evaluation parameters. Participants with Non-Erosive Gastroesophageal Reflux Disease divided into Grade N (endoscopically normal) and M (minimal change) by modified Los Angeles Classification System. Grade definitions: Grade N (endoscopically normal), M (minimal change), A (Mucosal break <5 mm) B (Mucosal break ≥5 mm) C (Mucosal break continuous between 2 or more folds and <75% of circumference) and D (Mucosal break ≥75% of circumference).
Week 4
Heartburn symptoms stratified by combination of response at Week 2 and baseline endoscopic findings (improvement and grade N, improvement and grade M, non-improvement and grade N, non-improvement and grade M.)
Time Frame: Week 4
Heartburn symptoms will be collected by participant diaries. Percentage of symptom-free days, cumulative symptom improvement rate, and severity of heartburn symptoms are evaluation parameters.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
