Further study details as provided by Eisai Inc. ( Eisai Co., Ltd. ):

Primary Outcome Measures:
  • Response rate of gastric low-grade MALT lymphoma by eradication of Helicobacter pylori [ Time Frame: Every 3 months within the 1st year and every 6 months ]
  • Transition rate to secondary therapy for eradication of Helicobacter pylori [ Time Frame: Every 6 months within the 1st year and every 12 months as needed ]

Enrollment: 108
Actual Study Start Date: January 13, 2011
Study Completion Date: November 17, 2016
Primary Completion Date: February 29, 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Treatment Arm 1 Rabeprazole Sodium Drug: Rabeprazole Sodium

The following 3 drugs are taken orally at the same time twice daily for 7 days: rabeprazole sodium 10 mg, amoxicillin hydrate 750 mg, and clarithromycin 200 mg.

The dose of clarithromycin may be properly increased as needed, although the upper limit is 400 mg twice daily.

If Helicobacter pylori eradication with proton pump inhibitor, amoxicillin, and clarithromycin fails, the following 3 drugs will be taken at the same time twice daily for 7 days as an alternative treatment for adults: rabeprazole sodium 10 mg, amoxicillin hydrate 750 mg, and metronidazole 250 mg.
