Phase 2
Completed
Conditions
Gastroesophageal Reflux Disease
Interventions
Drug: placebo
Registration Number

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.

Primary Outcome Measures
NameTimeMethod
Total Number of Reflux Episodes During 24 HoursMeasured 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
NameTimeMethod
Number of Weakly Acidic Reflux EpisodesMeasured 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.

Number of Weakly Alkaline Reflux EpisodesMeasured 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.

Number of Acid Reflux EpisodesMeasured 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.
