Inclusion criteria

* Prior to the run-in period, a history of heartburn or acid regurgitation for 3 months or longer or any history of EE; * Prior to the run-in period, nighttime heartburn averaging at least 2 or 3 times per week; * Prior to the run-in period, a history of sleep disturbances associated with GERD for 1 month or more;

Exclusion criteria

* Any condition other than GERD that is either the primary cause of, or a significant contributor to, the patient's sleep disturbance * Sleep medication (including over-the-counter), antihistamine, benzodiazepine, or anti-anxiety medication use that has not been stable (either in dose or regularity) for at least 3 months or is not expected to remain stable during the patient's participation in the study. Patients on a stable regimen, whose regimen is also expected to remain stable throughout the study, are eligible for participation; * Proton Pump Inhibitor (PPI) use within 1 week prior to Screening. The only allowable acid modifying rescue medication is GELUSIL® during the run-in period. Only study medication and rescue medication (GELUSIL®) is allowed during the treatment period for treatment of acid mediated symptoms

The baseline figures shown will be for the modified intention to treat population. One patient in each treatment group did not receive study drug; therefore, the safety population has one less patient in each treatment than does the randomized study population.
