Efficacy of ecabet sodium for Helicobacter pylori eradication triple therapy in comparison with a lansoprazole-based regimen

BACKGROUND: The cytoprotective agent, ecabet sodium, inhibits urease activity and growth of Helicobacter pylori. AIM: To evaluate the efficacy and safety of ecabet sodium-based eradication of H. pylori infection, compared with a lansoprazole-based regimen, in a randomized multicentre study. SUBJECTS AND METHODS: A total of 120 H. pylori-positive patients were assigned to one of two treatment regimens for 2 weeks: ecabet sodium 1 g b.d., amoxicillin 500 mg t.d.s. and clarithromycin 400 mg b.d. (EAC: 60 patients); or lansoprazole 30 mg (o.m.) with the same antimicrobial agents (LAC: 60 patients). Cure of infection was assessed by a 13C-urea breath test 1 month after completion of treatment. RESULTS: One patient in the EAC group and two in the LAC group did not complete therapy because of an adverse event, and three did not undergo the 13C-urea breath test. Cure rates for the intention-to-treat, all-patients-treated and per protocol analysis in the EAC group were 85%, 86% and 88%, respectively, whereas those in the LAC group were 85%, 88% and 91%. There were no significant differences in cure rate or adverse events between the two regimens. CONCLUSIONS: Ecabet sodium in combination with amoxicillin and clarithromycin is as effective as lansoprazole-based eradication therapy for H. pylori.
