[1] The RDQ is a 12 item survey that asks the patient to rate the frequency and severity of GERD symptoms. Each item is scored from 0 to 5 where a score of 0 is equivalent to an asymptomatic state and 5 indicates the worst severity of GERD symptoms. The total RDQ is a sum of all 12 items, and can range from 0 to 60.

  Outcome Measures

1.  Primary:   Percentage of Time Esophageal pH< 4   [ Time Frame: Days 1 and 2 ]

2.  Secondary:   Reflux Disease Questionnaire Score on Day 1 After Therapy Completion   [ Time Frame: Day 1 after therapy period completion ]

  Serious Adverse Events

  Other Adverse Events

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The limitations included the small sample size, a cohort of patients with primarily short-segment BE, and the fact that the study relied on comparison of intraoesophageal pH levels on Ome-NaBic to other PPIs based on historical controls.
