PRIMARY outcome

Timeframe: Measured during 24 hours at 4 different visits with a 7-28 days interval between

Population: Efficacy Analysis Set (EAS). From the safety analysis set with 27 patients, the EAS excludes 2 patients; 1 due to a positive drug of abuse screen and 1 due to poor quality of the impedance/pH tracings during all 4 study periods. Additionally, 3 patients were partly excluded from the EAS due to poor quality of the tracings during 1 study period.

Number of reflux episodes assessed during ambulatory impedance-pH recording (defined as starting with a drop in impedance to below 50% of baseline and ending when impedance recovers to above 50% of baseline)
