Comparative Efficacy of 14-Day Tegoprazan-Based Triple vs. 10-Day Tegoprazan-Based Concomitant Therapy for Helicobacter pylori Eradication
Abstract
Tegoprazan, a novel potassium-competitive acid blocker, is currently available for the treatment of Helicobacter pylori infection. We compared the efficacies of tegoprazan-based triple and concomitant therapies in a real-world practice. Data of patients treated with a 14-day tegoprazan-based triple therapy (50 mg of tegoprazan + 1000 mg of amoxicillin + 500 mg of clarithromycin twice daily) or 10-day tegoprazan-based concomitant therapy (50 mg of tegoprazan + 1000 mg of amoxicillin + 500 mg of clarithromycin + 500 mg of metronidazole twice daily) were retrospectively reviewed. Primary endpoint was eradication rate in the intention-to-treat (ITT) population. Of the 928 included patients, 551 and 377 were treated with triple and concomitant therapies, respectively. Eradication rate from ITT analysis was 76.4% (95% confidence interval [CI], 72.7−79.8%) in the triple therapy group and 85.9% (95% CI, 82.2−89.2%) in the concomitant therapy group (p < 0.001). Eradication rate in the per-protocol analysis was also higher in the concomitant therapy group than in the triple therapy group (triple vs. concomitant therapy: 84.5% [81.1−87.5%] vs. 91.1% [87.8−93.8%]). Overall adverse event rate was 29.0% in the triple therapy group and 45.9% in the concomitant therapy group (p < 0.001). Adherence rate was similar between the two groups (triple vs. concomitant therapy: 90.0 vs. 92.6%, p = 0.180). Overall, the 10-day tegoprazan-based concomitant therapy had superior efficacy than the 14-day…
