E.4 | Principal exclusion criteria |
A patient will be excluded from study participation if he/she meets any of the following criteria: 1. has exclusively atypical symptoms of GERD, such as coughing, sore throat, respiratory symptoms etc. (i.e. atypical symptoms in the absence of heartburn and / or regurgitation) 2. has symptoms that have been shown not to be associated with GERD, acid or non-acid 3. has a history of erosive oesophagitis as demonstrated by endoscopy within the previous 12 months of Grade B or worse (Los Angeles classification grading score) Patient's who have not had an endoscopy within the last 12 months are not eligible. 4. has a documented history of hiatus hernia > 3 cm 5. has a current diagnosis of co-existing psychiatric disease that, according to the investigator, could interfere with the conduct of the study 6. has a known clinically significant allergy or known hypersensitivity to drugs that, in the opinion of the investigator, may affect the patient’s safety 7. has clinically significant abnormal laboratory parameters at Screening, inparticular, liver or renal functions tests greater than twice the upper limit of normal (ULN) or any other clinically significant biochemical or haematological abnormality as determined by the investigator 8. has known or suspected human immunodeficiency virus (HIV) or hepatitis B or C 9. is pregnant or breast-feeding. Female patients who are of child-bearing potential must be using adequate contraceptive methods with a low failure rate of less than 1% per year (e.g. oral contraceptive, some intra-uterine devices, intra-muscular hormonal contraceptive), and have a negative pregnancy test at Screening and prior to randomisation on Day -1 10. is an habitual user of recreational drugs (including amphetamine, methamphetamine, cocaine and opiates), and who has used them within 14 days prior to Screening or has a positive test for drugs of abuse at Screening 11. has received sodium valproate or topiramate within 30 days of Screening 12. has a history of a significant medical condition that may affect the safety of the patient or preclude adequate participation in the study, including but not limited to coronary artery disease, chronic obstructive pulmonary disease, arrhythmias, diabetes and epilepsy 13. has received any investigational drug within 30 days of Screening |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy endpoint: The number of GERD symptom (heartburn and/or regurgitation) free days in week 2 of study medication (Days 8 to 14) adjusted for baseline will be evaluated. Baseline is defined as the last 7 days prior to randomisation (Day -8 to -2). |
