Efficacy and Safety of Tegoprazan-Based Dual, Triple, and Quadruple Therapies as First-Line Regimens for Helicobacter Pylori Eradication: A Prospective Randomized Controlled Trial

ClinicalTrials.gov · COMPLETED, 2026

640 participants

Abstract

Current first-line Helicobacter pylori eradication protocols involve multidrug regimens comprising a proton pump inhibitor (PPI) or bismuth agent combined with dual antibiotics (e.g., clarithromycin, amoxicillin, quinolones, furazolidone, nitroimidazoles, or tetracycline) administered for 7-14 days. In China, the bismuth-containing quadruple therapy (BQT) remains the standard first-line treatment for H. pylori infection. However, BQT implementation is challenged by polypharmacy burdens, substantial adverse events, and suboptimal treatment adherence. Emerging evidence suggests that simplified dual therapies pairing acid suppressants (PPIs or potassium-competitive acid blockers \[P-CABs\]) with high-dose amoxicillin achieve comparable eradication rates to BQT while demonstrating superior tolerability and adherence profiles. Notably, the comparative efficacy of tetracycline-based versus amoxicillin-based dual regimens remains unexamined in controlled clinical trials. Our preliminary investigations established that optimized PPI-amoxicillin dual therapy achieves \>90% eradication rates in treatment-naïve populations. Building on these findings, this prospective randomized controlled trial will comparatively assess the effectiveness of tegoprazan-a novel P-CAB exhibiting potent acid inhibition-when co-administered with either amoxicillin or tetracycline in H. pylori-positive adults. The investigation aims to establish an evidence framework for streamlining eradication protocols…

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: 640 participants or records.
