Study summary

This study is being carried out to see whether AZD3355 is an effective treatment as an add-on to PPI therapy in patients with Gastroesophageal Reflux Disease (GERD) with a partial response to PPI and to compare this with Proton Pump Inhibitor (PPI) treatment alone. Another goal of the study is to examine which of the investigated doses of AZD3355 is optimal for treatment of these patients. This study will also measure levels of drug in the blood and see how well it is tolerated.

What researchers measure

Primary outcomes

  1. Number of Participants With a Change in GERD Symptoms Corresponding to at Least Three More Days of Not More Than Mild Symptoms on Average Per Week During Treatment (Approximately 4 Weeks) Than During Baseline (the 7 Days Before Randomisation)

    Symptom intensity rated by participants twice daily on a six-graded Likert scale (Did not have; Very mild; Mild; Moderate; Moderately severe; Severe) using an electronic Reflux Symptom Questionnaire diary. (GERD = Gastroesophageal Reflux Disease)

    Time frame: The 7 days before randomisation (baseline) and during 26-30 days of treatment

Secondary outcomes

  1. Absolute Change From Baseline to Treatment Period in Percent Days With at Most Mild GERD Symptoms.

    Symptom intensity rated by participants twice daily on a six-graded Likert scale (Did not have; Very mild; Mild; Moderate; Moderately severe; Severe) using an electronic Reflux Symptom Questionnaire diary (GERD = Gastroesophageal Reflux Disease)

    Time frame: The 7 days before randomisation (baseline) and during 26-30 days of treatment

The record gives a start of Oct 2009, a primary completion of Jul 2010 and a completion of Jul 2010. It does not say whether these dates are actual or estimated.

Results were first posted in Apr 2011, 9 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 25, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
