Pantoprazole Magnesium 40 mg Versus Esomeprazole 40 mg in Patients With Erosive Gastroesophageal Reflux Disease

The aim of this trial is to evaluate the complete remission of erosive gastroesophageal reflux disease with pantoprazole magnesium 40 mg once daily versus esomeprazole 40 mg once daily during four-week treatment with an extension treatment for non-responding patients. The study includes a baseline period up to 14 days and a treatment period of either 4 weeks (28 -2 + 5 days), or 8 weeks depending on the cure of esophagitis due to gastroesophageal reflux. The study will provide further data on safety and tolerability of pantoprazole magnesium.

  • Systemic glucocorticoids and/or nonsteroidal anti-inflammatory drugs (including COX-2 inhibitors) for more than 3 consecutive days a week, within the last 28 days prior to start of study, with exception of regular intake of acetyl salicylic acid in dosages of up to 163 mg/day.

Treatment and study plan

Magnesium Pantoprazole

Drug

1 capsule daily, 40 mg, orally, 30 minutes before breakfast

Magnesium Esomeprazole

Drug

1 capsule daily, 40 mg, orally, 30 minutes before breakfast

Primary outcomes

  1. Comparatively evaluation of the clinical efficacy of pantoprazole magnesium and esomeprazole in the treatment of patients with erosive gastroesophageal reflux disease (GERD), considering the proportion of patients in complete remission.

    Time frame: After 4 treatment weeks

    A patient is considered at complete remission if he/she achieved symptoms relief and confirmed endoscopic healing at treatment end. A patient achieves symptoms relief if Reflux Questionnaire-GI score ((ReQuest™) stays below 1,73 for at least the three last consecutive treatment days, that can occur at visit V2 or visit V3 for those that did not achieve complete remission at V2 and repeated the treatment for 4 weeks more.

Secondary outcomes

  1. Treatments comparative evaluation for DRGE ReQuest™-GI and -WSO scores change with respect to baseline measured

    Time frame: After 4 and 8 treatment weeks

  2. Treatments comparative evaluation for the time interval from treatment start to the beginning of symptoms relief

  3. Treatments comparative evaluation for endoscopic healing rate

    Time frame: After 4 and 8 treatment weeks
