Fourteen-Day Vonoprazan-Based Dual Therapy With Amoxicillin as First-Line Helicobacter Pylori Treatment in Comparison With Extended Sequential Therapy: A Randomized Controlled Trial in Taiwan
Abstract
Background：Helicobacter pylori infection is a well-established risk factor for peptic ulcer disease and gastric cancer. It's now a consensus of experts that H.pylori infection should be treated once it is recognized. Extended proton pump inhibitor (PPI)-based sequential therapy as one of the most commonly used first-line regimens provides a satisfactory eradication rate of 90.7% (95% CI, 87.4% - 94.0%). Nevertheless, its complexity of the "sequential" usage is sometimes confusing to the patients and may lead to treatment failure. The emerging new regimen - vonoprazan-based dual therapy, on the other hand, is another appealing choice with simplicity, and low pill burden. However, there's still no evidence regarding the use of vonoprazan-based dual therapy with high-dose amoxicillin (1000mg twice daily) as the first-line regimen in Taiwan. This study aimed to compare the efficacy of the current standard first-line regimen, sequential therapy, with that of vonoprazan-based dual therapy with high-dose Amoxicillin.
Objectives: To compare the efficacy of the current standard first-line regimen, sequential therapy, with that of vonoprazan-based dual therapy, through a randomized controlled trial.
Methods: Patients with H.pylori infection who was over 20 years old and agree to participate in the trial will be recruited. Those who had received H.pylori eradication before, are known to be allergic to any drug used in this trial, are pregnant, or refuse to participate in the trial for…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 337 participants or records.
