Official Title: “The CONQUEST-Study. Evaluation of Clinical Endpoints for Treatment-Induced Changes in GERD-Related Symptoms”

The aim of the study is to compare two different endpoint measures: heartburn as assessed by the physicians versus gastroesophageal reflux disease (GERD)-related symptoms as assessed by the patient using the ReQuest™ questionnaire. The assessment is made in GERD-patients treated with a daily dose of 40 mg oral pantoprazole over an 8-week period.
