Outcomes
Primary outcome [1] 2216 0
The primary objective of this study is to compare in a non-inferiority design, the number of subjects with heartburn and regurgitation symptom resolution after 4 weeks of treatment with either rabeprazole 20mg, esomeprazole 20mg or esomeprazole 40mg. The degree of resolution will be defined as follows:
1. Complete resolution is the absence of symptoms for any 7 consecutive days within the 4 week period
2. Satisfactory resolution is a reduction in symptom severity from moderate, severe or very severe to mild, very mild or none at any time within the 4 week period.
Timepoint [1] 2216 0
Subjects assess symptom response daily with degree of resolution measured at week 4
Secondary outcome [1] 3862 0
1. Comparison of the number of subjects in each treatment group with resolution of other GORD symptoms, measured daily (fullness/ early satiety, nausea/ vomiting, bloating, upper abdominal pain and lower abdominal pain) where the degree of resolution will be defined as Complete or Satisfactory Resolution.
Timepoint [1] 3862 0
Measured at week 4
Secondary outcome [2] 3863 0
2. Comparison of the median time to first symptom resolution
Timepoint [2] 3863 0
Measured on a daily basis through patient self-evaluation until week 4.
Secondary outcome [3] 3864 0
3. Comparison of the number of heartburn and regurgitation symptom free days

7. Analysis of factors predictive of outcomes·
Timepoint [7] 3868 0
patients will be evaluated once at baseline and once at the end of the 4 weeks. The patients will self-evaluate symptom resolution on a daily basis throughout the 4 weeks.
Secondary outcome [8] 3869 0
8. Evaluation of safety and tolerability of treatments
Timepoint [8] 3869 0
patients will be evaluated once at baseline and once at the end of the 4 weeks.

Summary
Brief summary
The primary purpose of the TREAT study is to compare the number of subjects in which heartburn and regurgitation symptoms resolve after being treated with either PARIET 20mg, NEXIUM 20mg or NEXIUM 40mg. All 3 medications are commonly prescribed for Gastro-oesophageal Reflux Disease (GORD). It is hypothesised that PARIET 20mg will be non-inferior to NEXIUM 40mg in resolving GORD symptoms.
