Eligibility | Inclusion Criteria: 1. Patient with a primary diagnosis of symptomatic GORD in accordance with the Montreal definition. Patients must have experienced frequent troublesome heartburn and / or regurgitation (with or without dyspepsia symptoms) of mild/moderate intensity. If the patient also has other symptoms, the heartburn, regurgitation or dyspepsia should be the predominant symptoms. 2. Patient that are healthy (with the exception of a diagnosis of GORD) as determined by past medical history and vital signs at screening. Exclusion Criteria: 1. Patients with a history or active gastrointestinal disease (gastroduodenal ulcer, gastrointestinal haemorrhage, mechanical obstruction or perforation) or hiatus hernia which is greater than 3 cm or a history of conditions that can lead to abnormal oesophageal pH. 2. Patients experiencing frequent troublesome heartburn and / or regurgitation (with or without dyspepsia symptoms) of severe intensity 3. Patients who are unwilling to refrain from using antacids or alginates 24 hours prior to the start of the treatment visit. 4. Patients who are unwilling to refrain from using proton pump inhibitors (PPIs), H2 antagonists, motility stimulants or other medicines for relief of symptoms of acid reflux disease 2 weeks prior to the start of treatment period. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | To measure efficacy of the calcite chewing gum versus unmatched placebo by measurement of the mean percentage of time (%) that the pH of the oesophagus is greater or equal to 4 up to 1 hour post dosing | The mean percentage of time (%) that pH is greater or equal to 4 within the oesophagus during the 0-1 hour post dose monitoring period. | 0 to 1 hour post dose | |
Secondary | To evaluate the efficacy of the test product versus the unmatched placebo by measurement of the time (mins) taken to observe the first non-acidic reflux event (pH greater or equal to 4 throughout event) immediately after the start of dosing | Time (mins) to first non-acidic reflux event (pH greater or equal to 4 throughout event) | 0 to 2 hours post dose | |
Secondary | To evaluate the efficacy of the test product versus the unmatched placebo by recording the number of acid reflux events (pH is below pH 4) for up to 2 hours post dose | The number of acid reflux events (pH is below pH 4) for up to 2 hours post dose | 0 to 2 hours post dose | |
Secondary | To evaluate the efficacy of the test product versus the unmatched placebo by recording the total number of reflux events up to 2 hours post dose | The total number of reflux events for up to 2 hours post dose | 0 to 2 hours post dose | |
Secondary | To evaluate the efficacy of the test product versus the unmatched placebo by recording the mean percentage of time (%) that the pH within the oesophagus is raised greater or equal to 4 over the period 1-2 hour post dose | The mean percentage of time (%) that pH is greater or equal to 4 within the oesophagus during the 1-2 hour post dose monitoring period. | 1 to 2 hours post dose | |
Secondary | To evaluate the efficacy of the test product versus the unmatched placebo by recording the mean percentage of time (%) that the pH within the oesophagus is raised greater or equal to 4 over the period 0-2 hour post dose | The mean percentage of time (%) that pH is greater or equal to 4 within the oesophagus during the 0-2 hour post dose monitoring period. | 0 to 2 hours post dose |
