Study Description
Brief Summary:
The purpose of the study is to estimate what effect 4 different doses of AZD3355 will have on the number of reflux episodes, in patients who have GERD and still experience symptoms despite proton pump inhibitor (PPI) treatment.

Condition or disease Intervention/treatment Phase
Gastroesophageal Reflux Disease Drug: AZD3355 Drug: placebo Phase 2

Study Design

Study Type : Interventional  (Clinical Trial)

Outcome Measures

Primary Outcome Measures :
  1. Total Number of Reflux Episodes During 24 Hours [ Time Frame: Measured during 24 hours at 4 different visits with a 7-28 days interval between ]
    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)


Secondary Outcome Measures :
  1. Number of Acid Reflux Episodes [ Time Frame: Measured during 24 hours at 4 different visits with a 7-28 days interval between ]
    Number of reflux episodes as defined for the primary outcome measure with an intraesophageal pH <4 (or a drop of at least 1 pH unit if pH is already <4) lasting more than 5 s.

  2. Number of Weakly Acidic Reflux Episodes [ Time Frame: Measured during 24 hours at 4 different visits with a 7-28 days interval between ]
    Number of reflux episodes as defined for the primary outcome measure with an intraesophageal pH 4.0-6.5 lasting more than 5 s.

  3. Number of Weakly Alkaline Reflux Episodes [ Time Frame: Measured during 24 hours at 4 different visits with a 7-28 days interval between ]
    Number of reflux episodes as defined for the primary outcome measure with an intraesophageal pH ≥6.5 lasting more than 5 s.
