ABSTRACT
BACKGROUND & AIMS:
Previous studies confirm vonoprazan-amoxicillin effectiveness for Helicobacter pylori. This study aims to investigate vonoprazan with varying amoxicillin dose and duration.METHODS:
This multicenter, prospective, randomized controlled, noninferiority trial enrolled patients with treatment naive H pylori infection from 5 clinical centers. Eligible participants were randomly assigned to H-VA-10 (vonoprazan 20 mg twice a day (b.i.d.) + amoxicillin 750 mg 4 times a day, 10 days), L-VA-10 (vonoprazan 20 mg b.i.d. + amoxicillin 1000 mg b.i.d, 10 days), and H-VA-14 (vonoprazan 20 mg b.i.d + amoxicillin 750 mg 4 times a day, 14 days) in a 111 ratio. The eradication rate was assessed using the 13C-urea breath test at least 28 days after treatment.RESULTS:
Of the 623 eligible patients, 516 patients were randomized. In both the intention-to-treat and per-protocol analyses, eradication rates were comparable between H-VA-10 and H-VA-14 groups (86.6% vs 89.5% and 90.9% vs 94.5%, P = .021 and .013 for noninferiority, respectively). However, eradication rates were significantly lower in the L-VA-10 group than the H-VA-14 group (79.7% vs 89.5% and 82.0% vs 94.5%, P = .488 and .759, respectively). Rates of study withdrawal, loss to follow-up, and adverse events were similar across study groups.CONCLUSIONS:
H-VA-10 and H-VA-14 regimens provide satisfactory efficacy for H pylori infection, and the L-VA-10 regimen was inferior. CLINICALTRIALS gov number NCT05719831.Palavras-chave
