Background and Aim This was a prospective, randomized trial of the efficacy of vonoprazan-based and proton-pump inhibitor-based 7-day triple regimens with amoxicillin and sitafloxacin as a third-line therapy for eradicating Helicobacter pylori after failure of clarithromycin-based and metronidazole-based first-line and second-line therapy. Methods We enrolled 63 patients positive for H. pylori in whom first-line and second-line regimens for eradicating failed. Patients were randomized to the V-AS group (vonoprazan 20-mg bid, amoxicillin 750-mg bid, and sitafloxacin 100-mg bid for 7 days) or PPI-AS group (esomeprazole 20-mg bid, rabeprazole 10-mg bid, or lansoprazole 30-mg bid; amoxicillin 750-mg bid; and sitafloxacin 100-mg bid for 7 days). We assessed the outcome of eradication therapy using the C-13-urea breath test. We evaluated safety using patient questionnaires. This study was registered in the UMIN Clinical Trials Registry (UMIN000016336). Results The intention-to-treat and per-protocol eradication rates of V-AS were 75.8% (95% confidence interval [CI]: 57.7-88.9%) and 83.3% (95% CI: 65.3-94.4%), respectively. The respective eradication rates of PPI-AS were 53.3% (95% CI: 34.3-71.7%) and 57.1% (95% CI: 37.2-75.5%). In per-protocol analyses, the eradication rate of the V-AS group was significantly higher than that of the PPI-AS group (P = 0.043); however, no significant differences were observed in intention-to-treat analyses (P = 0.071). Questionnaire scores did not differ significantly between the groups. Conclusions The findings suggest that 7-day triple therapy with vonoprazan, amoxicillin, and sitafloxacin is more effective than proton-pump inhibitor, amoxicillin, and sitafloxacin as a third-line regimen for eradicating H. pylori.
